Thesis (MBA (Business Management))--University of Stellenbosch, 2009.ENGLISH ABSTRACT: This research report discusses the development of a decision-making matrix during power crises. South Africa comes from a situation of excess supply and is currently in a situation where electricity demand exceeds supply. This report will provide the background of how the current electricity crisis came to be and what the future of the industry will look like. As electricity shortages is a worldwide issue, the study will explore international countries' experience of supply shortages and extract lessons learnt and best practices that can be applied in the South African context. The study reviews available solutions that exist to address the electricity crisis in South Africa and explores alternative energy sources that could be applied in South Africa. To establish an effective decision making tool for electricity shortage response mechanisms, the key decision making criteria are discussed and explained. A decision making matrix brings together all the available solutions and decision-making criteria based on the decision maker's relative importance placed on the considerations and the resultant impact on these considerations. The results of the decision-making matrix directs the decision maker to the least negative impact solution and provides a basis on which to make sound decisions during a time when quick and effective decisions will determine the success and sustainability of the power system.
AFRIKAANSE OPSOMMING: Hierdie navorsingsverslag bespreek die ontwikkeling van 'n besluitnemingsmodel wat aangewend kan word tydens kritiese tekorte in elekrisiteitsvoorsiening op 'n nasionale basis. Die elektrisiteits- ontwikkelingsvermoë in Suid-Afrika het beweeg vanaf 'n oorskot na 'n posisie waar daar nie in die aanvraag voorsien kan word nie. Hierdie navorsingsverslag skets die agtergrond van wat aanleiding gegee het tot die huidige elektrisiteitskrisis en wat die toekoms inhou vir elektrisiteitsvoorsiening in die algemeen. Die gebrek aan elektrisiteitsontwikkelingsvermoë is 'n wêreldwye tendens en die lesse wat ander lande geleer het tesame met hul beste praktyke word oorweeg binne die Suid-Afrikaanse konteks. Beskikbare oplossings wat op die manier geidentifiseer word, word ontleed, tesame met moontlike alternatiewe energiebronne wat in Suid-Afrika aangewend kan word. Die kern besluitnemingskriteria word bespreek en ontleed om sodoende 'n proses daar te stel waarvolgens die besluitnemingsmodel wat die mees effektiewe oplossing in tye van kritiese elektirsiteitstekorte sal voortbring te ontwikkel. Al die beskikbare en werkbare opsies tydens die periode van elektristeitstekorte word saamgevoeg binne die besluitnemingsmodel om die toepaslikheid daarvan op te weeg teenoor die relatiewe gewig wat die besluitnemer toeken aan al die onderliggende faktore. Die besluitnemingsmodel ondersteun die besluitnemer om, tydens 'n krisis in elektrisiteitsvoersiening, 'n vinnige en doeltreffende besluit te neem wat die minste negatiewe impak het op ekonomiese aktiwiteite en die sukses en stabiliteit van die elektrisiteitsvoorsieningsnetwerk waarborg.

Purpose of this treatise: The aim of this research is to determine, if the skilled labour shortage has had any impact on how construction projects are executed. If there is an impact the study aims to determine the nature and extent of the problem. Design/methodology/approach: A review of related literature was conducted, mainly to ensure that existing research is not replicated, in order to generate new ideas. The quantitative research approach was applied for this research. The questionnaire was designed so that scores can be easily summed in order to obtain an overall measure of the attitudes and opinions of the respondents. Findings: The results revealed that the skilled labour shortage has a negative effect on how construction projects are executed. The results further revealed that the biggest concern amongst employers and management of construction companies was the negative impact the shortage of skilled labour has on the levels of workmanship. Research limitations: The sample (construction companies) is mostly situated in the Gauteng province of South Africa. Practical implications: The research is of importance to managers and supervisors of construction companies of all sizes. The findings of this study will assist in ensuring that projects are efficiently managed irrespective of the current skills crisis in the construction industry.

Thesis (MBA)--Stellenbosch University, 2000.ENGLISH ABSTRACT: The South African Electricity Distribution Industry is riddled with tariffs. Every utility in South Africa probably uses some method for allocating cost, whether it is theoretically founded or not. There are currently over 2000 different tariffs in South Africa and the need for rationalisation has been widely recognised and acknowledged. Many of these tariffs have not been the outflow of accepted methodologies but rather a function of individual utility policy and practices. There is however a dire need to standardise such methodologies in the future. A standardised methodology might be the only way to eventually rationalise the thousands of tariffs that exist in the electricity industry. Government has emphasised the importance of tariffs to be cost reflective in the future. The only possible way to reach this objective would be to determine clear and concise methods of allocating cost that can be utilised by the entire industry. This study project describes a standardised methodology for determining the cost to supply different customer categories in an electricity distributor. The methodology offers enough flexibility not to bind any party into laboursome, complex and time consuming costing activities. It does however require that the costs of a distributor are carefully investigated and all functions performed in the utility are isolated. This is referred to as ringfencing of costs.
AFRIKAANSE OPSOMMING: Die Suid-Afrikaanse Elektrisiteitverspreidingsbedryf het veelvuldige tariewe. Elke utiliteit in Suid-Afrika gebruik waarskynlik 'n metode vir kostetoedeling, wat nie noodwendig teoreties gebaseer is nie. Huidiglik is daar meer as 2000 verskillende tariewe in Suid-Afrika en dit word alom besef en erken dat gronde vir rasionalisering bestaan. Baie van die tariewe het nie ontstaan uit die gebruik van aanvaarbare berekeningsmetodes nie, maar was eerder die gevolg van individuele beleid en praktyke van utiliteite. Daar is 'n dringende behoefte om hierdie berekeningsmetodes in die toekoms te standardiseer. 'n Standaard metode mag die enigste manier wees om uiteindelik die duisende tariewe wat in die elektrisiteitsbedryf bestaan te rasionaliseer. Die regering het die belangrikheid dat tariewe in die toekoms koste reflekterend moet wees benadruk. Die enigste moontlike manier om hierdie doelwit te bereik, is om helder en duidelike metodes vir koste toedeling te bepaal vir gebruik deur die hele bedryf. Hierdie verhandeling beskryf 'n standaard metodologie om die koste te bepaal om verskillende klantegroepe in 'n elektrisiteitsverspreider van krag te voorsien. Die metodologie bied voldoende plooibaarheid om geen party aan arbeidintensiewe, kompleks en tydrowende kostebepalings te verbind nie. Dit vereis egter dat die koste van 'n verspreider noukeurig ondersoek word en dat alle funksies wat verrig word uitgelig word. Hierna word verwys as afbakening van kostes.

Thesis (MPhil)--Stellenbosch University, 2010.ENGLISH ABSTRACT: South Africa has a mean annual precipitation far lower than the global average. This is a fundamental constraint to development, especially when the country has already run out of surplus water and dilution capacity. To add further pressure, Southern Africa’s water resources are expected to decrease as a result of climate change. Despite the potential devastation, the country’s response to climate change has been limited. South Africa’s energy sector is dominated by coal power stations and is the country’s primary emitter of carbon dioxide. Given the significantly higher water usage of coal-fired power plants compared to that of most renewable energy power plants, the transition to a clean energy infrastructure might be more successfully motivated by water scarcity than by the promise of reduced carbon emissions. This article analyses more critically the impact of coal-fired electricity generation on South Africa’s water resources, by estimating a water-use figure that extends backwards from the power plant to include water used during extraction of the coal. This figure can then be compared to the water usage of alternative electricity generation options. It is then possible to estimate how much water could be saved by substituting these alternatives in place of additional coal-fired plants.
AFRIKAANSE OPSOMMING: Suid-Afrika se gemiddelde jaarlikse neerslag is baie laer as die wêreldwye gemiddelde. Dit plaas ’n wesenlike beperking op ontwikkeling, veral aangesien die land se surplus water- en verdunningskapasiteit reeds uitgeput is. Om die saak verder te vererger, word verwag dat Suidelike Afrika se waterbronne gaan kleiner word as gevolg van klimaatsverandering. Ten spyte van die potensiële ramp, was die land se reaksie op klimaatsverandering tot dusver baie beperk. Steenkoolkragstasies, wat Suid-Afrika se energiesektor oorheers, is die land se primêre bron van koolstofdioksieduitlating. Gegewe die beduidend hoër waterverbruik van steenkoolkragstasies teenoor dié van die meeste kragstasies wat met hernubare energie werk, kan die verandering na ’n skoonenergie-infrastruktuur meer suksesvol gemotiveer word deur waterskaarste as deur die belofte van verminderde koolstofuitlatings. Hierdie artikel analiseer die impak van steenkoolgedrewe elektrisiteitsopwekking op Suid-Afrika se waterbronne meer krities deur te beraam hoeveel water verbruik word van die kragstasie terug tot by die ontginning van die steenkool. Hierdie syfer kan dan vergelyk word met die waterverbruik van alternatiewe kragopwekkingsopsies. Dit is dan moontlik om te beraam hoeveel water gespaar kan word deur hierdie alternatiewe op te rig in plaas van bykomende steenkoolkragstasies.

Full textAbstract:
In a research study, which focused on a strategy to link informal and formal motor mechanic artisan training, a number of constraints leading to the shortage of artisans in general were identified in the literature. Disparities between big businesses and the informal sector were highlighted. Emphasis was placed on the need for a growth initiative, which would include the informal practising motor mechanic, to address the key constraints and obstacles encountered in the development and implementation of artisan training for South Africa. The study was explorative and a qualitative research design followed. The researcher used semi-structured interviews to collect data from 16 (n = 16) experts in the field of training automotive artisans. A purposive snowball sampling method was applied to select participants from educational sectors (public and private FET colleges), automotive organisations and organised labour with the common characteristic of involvement in the training of motor mechanic artisans. The key themes identified in the different participants’ responses formed the data for the study, which was analysed by means of the ATLAS.ti 7.0 version data analysis program. The research confirmed that a strategy could be developed to successfully link the informal and formal motor mechanic artisan communities.

Bibliography: p. 173-182.The objective of this dissertation was to investigate compressed air energy storage as an alternative generation capacity for the South African electricity industry. In chapter one, an introduction to energy storage, electrical energy storage was introduced as an alternative generation option. Various energy storage technologies were discussed with their characteristics and applications. Compressed air energy storage was identified as a competitive energy storage option to pumped hydro in particular, and a suitable contender for the South African electricity market. In chapter two, the literature review, an in-depth study into compressed air energy storage was conducted. Many aspects of CAES were covered including CAES variants, underground pressurised air storage, projects and pre-feasibility studies, and operational plants. Due to the additional fuelling that certain CAES variants require, a Charge Energy Factor and a Fuel Heat Rate were defined. From the literature review it was seen that to date, only two CAES plants are still in operation. They are both of the conventional CAES type and use fuel-oil or alternatively natural gas for combustion In chapter three, an analysis of Eskom's demand, Eskom's future demand growth was analysed. A prediction in load growth, based on several economic scenarios, was made and the capacity of a suitable CAES plant, to meet this future demand, was determined. Chapter four, underground air storage reservoirs, focused on the aspects and prospects of storing compressed air underground in South Africa. Past underground air storage in South Africa was discussed and unused goldmines were identified as the most convenient and cost effective storage volumes available. The uniqueness of individual underground air storage volumes in mines were discussed as well as techniques necessary for the conversion of existing cavities. Both constant volume and constant pressure systems were investigated and mine cavern conversion costs where estimated per electric energy generated (R/kWh). Two of the most likely CAES turbo-machinery configurations suitable for South Africa were evaluated in chapter five, conceptual designs and cost analysis. The two types of CAES were conventional CAES and CAES with pressurised fluidised bed combustors (CAESIPFBC). Available plant was discussed and future generating capacities of individual CAES turbo-machinery trains were predicted. Costs per kW for CAES plants, excluding the cavern, were estimated through the escalation of costs from other plants and sources.

Bibliography: leaves 65-70.Low access to electricity is a problem in Africa. Apart from South Africa and Mauritius access to electricity generally falls below 30% of the population. The situation is even worse in the rural areas which housed about 70% or more of the population and whose access to modern energy services in these areas is between 5%-10%. Hence, this work aims at providing means of increasing access to electricity for the larger portion of the continent. This work looked at the potential of using bagasse, a waste from sugar production, to produce electricity beyond the sugar factory to the national grid. It shows that bagasse generated electricity can contribute to increasing this access in Africa as a whole by as much as 9.4 TWh, using Condensing Extraction Steam Turbines. However, this increase varies among countries with the highest being Swaziland, 67%, and the lowest South Africa, 1.5%, due to the current capacity. The actualization of this technical potential, however, can only come about with proper application of relevant policies and measures that need to be in place for Africa in general and South Africa in particular as more detailed work was done on the latter. Due to limitation in scope, this work did not cover the social, financial and agronomic aspects and neither was optimization of sugar considered in evaluating electricity from bagasse.

Full textAbstract:
Since 1994, with many of its sanctions lifted, South Africa became a stronger economic power house in Africa leading the continent‘s industrial output and mineral production and generating a large proportion of Africa‘s electricity. The South African economy has since been growing at a fast pace which has also led to an increase in the demand for electricity. South Africa‘s generating capacity has remained constant through a consistently increasing demand, leading to an electricity shortfall. An immediate threat to South Africa‘s continued economic growth is a capacity constraint in terms of energy supply. Increasing economic growth coupled with the rapid industrialisation and mass electrification programme of the last decade, as well as planned and unplanned maintenance and coal stock pile problems led, in January 2008, to demand out stripping supply. With electricity being an important component of economic development, it is vital that the impact of the supply of electricity on the economic growth of the country be well understood. Currently few studies have been done on the analysis of this relationship in South Africa specifically and how this relationship impacts specific sectors of the economy that contributes to the total GDP of the country. This study has assumed rigorous application of Granger technique with proper statistical verification of assumptions, selection of relevant variables and provides trusted statistical forecasts. In an attempt to understand this relationship, an Econometric model has been developed to assess the impact of electricity supply and price on the economic growth of South Africa. In the empirical analysis section of this study it was found that with a forecast for GDP, past values of electricity prices and coal sales may be used to forecast electricity supply. It was also found that if we have a forecast value of future electricity price we can use past values of electricity supply and coal sales to forecast GDP for the next quarter. We also found that electricity supply is granger caused by GDP; electricity price; and total coal sales. And that economic growth is granger caused by electricity supply; electricity price; and total coal sales. It was concluded that in order for government to improve the economic growth of South Africa, a major focus on the energy industry is needed to ensure sustainable supply capacity. The energy sector, as was shown in the study, has a major impact in the functioning of the Gross Domestic Product of the country.

Includes bibliographical references (leaves 132-135).Integrated resource planning aims to fulfil electricity requirements with supply and demand resources. Least cost resources are optimised as supply expansions compete with measures to modify the load in meeting energy services. A demand side study is conducted to determine representative load profiles for electricity use within South Africa. Analysis of electricity consumption us in g load profiles of each sector ' s end-use electrical loads is essential for determining the appropriate supply technologies as well as the impact of demand side management and energy efficiency measures . A supply side study considers all existing and future power generation options required for expected electricity growth and system load characteristics. Energy model, TIMES, provides time-slices for adequate load profile representation TIMES is a Partial Dynamic Equilibrium Model as constraints are placed on the investment, usage and availability of technologies. All optimisations are for the least cost to the system. Demand and supply options are integrated into a single plan using the TIMES model and the supply expansion plan is changed when demand reduction targets are achieved using DSM and EE. The base case us in g a business-as-usual approach is compared with a low and medium impact DSM and EE scenario. Demand resources are estimated from the industrial, commercial and residential economic sectors. The scope of the plan is 22 years and there is full utilisation of all existing supply capacity with small amounts of decommissioning. Mothballed power stations are recommissioned initially. Peak-load plants are needed from 2007 and OCGT are selected using natural gas or LNG. Intermediate-load capacity is needed by 2011 using CCGT. Base-load capacity demands are met using new coal PF power stations in 2014. FBC stations using discard coal begin operation in 2016. The capacity expansion plan anticipates 2. 93GW of OCGT, 2.5 GW of CCGT, 7. 2GW of coal PF, 2. 8 GW of FBC plants and 2 GW of pump storage stations to be in use by 2020. Imported hydroelectric capacity of0.9 G W and PBMR capacity of3 GW is expected to be commissioned by 2024. Approximately 4 % less installed capacity is needed when a medium impact DSM and EE strategy is implemented. The marginal cost of energy gradually increases from 0. 06 R/kWh in 2002 to 0. 175 R/kWh in 2016 and to 0.325 R/kWh in 2024 as supply capacity is added. Compound load profiles from all national electricity usage provide an effective means whereby appropriate supply technologies are selected whilst incorporating load modifications due to DSM and EE.

The increasing demand for electricity, the rising price of energy from conventional sources and limited electricity supply are a global concern. The demand on electricity generation could be alleviated by diversifying the sources from which electricity is obtained to achieve the goals of long-term electricity supply. Diversification implies finding alternative sources of energy such as renewable energy for the production of electricity. The South African electricity system is under increased pressure to provide and maintain electricity supply to its users. Electricity production may be regarded as a key contributor to the social and economic development of South Africa. The challenges are so serious that it will gradually become increasingly difficult to extract sufficient resources to satisfy increasing electricity demand. Growth in the electricity and industrial sectors signifies profound changes in the entire energy industry. The South African power utility Eskom, supplies 94% of South Africa’s electricity but the risk of inadequate supply because of increasing electricity demand is mitigated through the employment of Independent Power Producers (IPPs) which supply to the grid. However, although a limited number of IPP entrepreneurs sell electricity to the Eskom grid, there is no enabling entrepreneurial environment in which they can thrive. There is no positive movement to inaugurate policies and processes. This has created an opportunity for Smart Grid access as a viable option to accommodate IPP entrepreneurs into the grid. Investing in renewable electricity sources may provide feasible alternatives for the electricity industry, it would alleviate pressure on current supply whilst creating an enabling entrepreneurial environment for IPP entrepreneurs and increase entrepreneurial activity. This study investigates a proposed model for an enabling entrepreneurial environment for IPPs in the RE sector that can be utilised to ensure increased entrepreneurial activity within the electricity industry. Establishing such an enabling environment would contribute positively to the alleviation of the electricity demand crisis, result in lower carbon emissions and create a sustainable, more diverse electricity generation mix. This proposed IPP industry model for an enabling entrepreneurial environment is presented to address the problems experienced at the different levels of the electricity industry. The model can be utilised to increase entrepreneurial activity while eradicating major electricity challenges at different levels in the South African electricity industry. The results indicate that that RE, in the form of solar and wind, has the potential to expand the South African electricity industry significantly. Therefore, in order to reform the South African electricity industry, stakeholders need to embrace entrepreneurship as IPP entrepreneurs. This can be done effectively by the incorporation of IPP entrepreneurs into the electricity network. However, an enabling entrepreneurial environment in which to operate must be ensured. In this study, five important variables support the establishment of an enabling entrepreneurial environment for IPP entrepreneurs. These have been identified as; Smart Grids, Entrepreneurship, Renewable electricity environment, SA policy and Stakeholder theory. An important contribution has been made towards Stakeholder Theory. This has proven to be instrumental within the RE sector of the electricity industry in South Africa, as the mentioned role players have a reciprocal role to play. Three surveys were conducted at three levels of the electricity industry, namely, at organisational, legislative and entrepreneurial levels and included Eskom Management, National Energy Regulator (NERSA) Management and Approved and Non-approved IPPs. Both qualitative and quantitative research methods were utilised in this research study. The results indicate that SA Policy is instrumental in assisting stakeholders to facilitate the IPP process and feed the power from RE generation into the network. Most respondents were positive about the role of Smart Grids in future electricity generation and their contribution towards creating an enabling entrepreneurial environment for IPP entrepreneurs. Respondents indicated that by policy decisions, greater emphasis can be placed on the results of climate change and environmental challenges. Emphasis on the incorporation of stakeholders proved imperative to this group (IPPs). The results indicated that stakeholder management is a key factor contributing to the establishment of an enabling entrepreneurial environment. The major contribution of this study is a proposed entrepreneurial model that can improve future sustainability of the electricity supply.

Full textAbstract:
Since democratisation of South Africa in 1994, the economy of South Africa underwent significant structural changes. Among these structural changes was electrification for the poor rural areas. During the apartheid era, about two-thirds of the nation lacked access to electricity and hence, provision for electricity to everyone was considered a crucial part of the economic development, post 1994. Since then economic growth and the demand for electricity in South Africa have been increasing at an unprecedented rate. The electricity supply did not increase proportionally to the increase in the consumption of electricity. In responding to the high increase in the demand for electricity, the electricity utility planned to build new power stations and put back in use the ones which were mothballed. But unfortunately the plan for investment in these power stations was late and in 2008, the existing power stations could not manage to supply enough electricity. The demand for electricity was such that it nearly damaged the power generating circuit and the electricity supply utility had to resort to load shedding. The imbalance between electricity supply and demand led to industrial sectors losing on production and as a result led to a downturn in economic growth. It also led to an increase in electricity prices which had a negative effect on individual and private sectors’ purchasing power. It is against this background that this study is designed to investigate the long term relationship between economic growth and electricity supply. The additional variables such as electricity prices, trade openness, capital and employment were included as intermittent variables to form a multivariate framework. This study also assesses the Granger causality between these variables to determine which variable supersedes the other. Two models were applied in this study: The Auto-regressive Distributed Lag (ARDL) bounds approach and the Vector Error Correction Model (VECM) Granger-causality. The ARDL bounds technique was used to detect the long term relationship between economic growth, electricity supply, electricity prices, trade openness, capital and employment using annual data from 1985 to 2014. The ARDL technique was chosen over the conventional models such as Engle and Granger (1987) and Johansen (1988) for the research for the following reasons: Firstly, the ARDL technique uses a single reduced form of equation to examine the long term relationship of the variables as opposed to the conventional Johansen test that employs a system of equations. Secondly, it is suitable to use for testing co-integration when a small sample data is used. Thirdly, it does not require the underlying variables to be integrated of similar order e.g. integrated of order zero I(0), integrated of order one I(1) or fractionally integrated, for it to be applicable. Lastly, it does not rely on the properties of unit root datasets and this makes it possible for the Granger-causality to be applied in testing the long term relationships between the variables. The VECM Granger-causality is used to examine the Granger-causality between the chosen variables. It was chosen for its ability to develop longer term forecasting when dealing with an unconstrained model. The unit root results confirmed that the variables were stationary at first difference using Augmented Dickey Fuller (ADF), Phillips and Perron (PP) and Kwiatkowski-Phillips-Schmidt-Shit (KPSS). The ARDL bound approach outcomes revealed that economic growth, electricity supply, trade openness, electricity prices, employment and capital move together in the long term. There were three co-integrated equations under the export and trade models while under the import model there was one co-integrated equation. The results are such that electricity prices have a negative impact on economic growth. The results further evidenced that; electricity supply, trade openness, employment and capital have a positive impact on economic growth in the long term. The VECM Granger causality findings suggested a unidirectional causality flowing from electricity supply, trade, exports, electricity prices, employment and capital to economic growth in the long term. There was another unidirectional causality established flowing from economic growth, trade openness, electricity prices, employment and capital to electricity supply. A one-way causality flowing from economic growth, electricity supply, electricity prices, employment and capital to export was evidenced. Overall, the study’s results of bidirectional Granger-causality between electricity supply and economic growth have a number of implications for forecasters and policy makers. This feedback hypothesis implies that the high level of economic growth leads to a high level of electricity supply, which would stimulate economic growth. Hence, South Africa demonstrates a kind of electricity dependence in a manner that a sufficiently large supply of electricity seems to ensure high economic growth. Electricity supply is a vitally important factor for economic growth in South Africa. It is therefore necessary that South African policy makers formulate investor friendly policies that will encourage, promote and attract capital inflows to stimulate electricity supply. The South African government needs to primarily deregulate the electricity supply industry which is owned by Eskom (a monopoly), and allow more investors into this industry. The government should promote a change to other forms of energy sources such as renewable energy sources which will play an important role in restoring the balance between electricity supply and consumption. Moreover, it is recommended that the electricity regulator should take steps to curb the severe electricity price increases and to ensure prices affordable to the poor communities. The policy makers need to implement some investor friendly policies that will encourage and promote capital formation. Furthermore, the government should invest towards more job creating sectors such as (Small and Medium Enterprises) SMEs. Finally, the government should take into consideration the importance of trade openness to attract international investments into the economy. It is hoped that the findings of this study would prove beneficial to policy makers in South Africa and elsewhere in the world where power outages are experienced, and assist them in combating the problem.

Full textAbstract:
Efficiency analysis in the public sector assesses the performance of municipal and government entities in their provision of services to the public. South Africa, in particular, has experienced a large degree of negative feedback with respect to the ability of the government and its municipal departments to provide basic services to citizens. This has led to a number of service delivery protests throughout the country. To remedy this, the ability of the municipality to provide basic services needs to be assessed in order for improvements to be made. A first step in this process would be to determine the efficiency with which municipalities are providing these services. This study focuses on a particular municipal service, namely electricity distribution. Primarily, the efficiency with which municipalities provide electricity to consumers is determined. This is achieved using the parametric cost frontier approach, which is appropriate since municipalities aim to reduce the costs incurred in distributing electricity. The municipalities are compared to a frontier (theoretical best practice) from which inferences on their performances can be made. Those municipalities whose performances are not optimal, deviate from the frontier. The deviations (errors) are then assumed to be caused by two factors, namely stochastic random noise and inefficiency. This composition accounts for effects for which municipalities cannot control (stochastic random noise) and those for which it can (inefficiency). The parametric nature of the cost frontier approach allows for distributional assumptions to be made on these factors. Stochastic random noise is always assumed to be normally distributed, while inefficiency is assumed to be one-sided and positively skewed.

This would entail the merging of the national electricity utility, Eskom Distribution with municipalities to consolidate skills and to improve on efficiencies. This integration would involve the assimilation of not only physical assets but also various organisational cultures into a separate organisation responsible for supplying electricity services within its designated geographical area. A separate challenge facing Eskom is an intensive capital expansion program to increase generation capacity which will require a committed workforce to execute. Organisational culture has been regarded as leading to greater productivity and generating commitment to the values and philosophies of the organisation. The purpose of the research was to determine whether there was a significant relationship between the organisational culture, organisational commitment and employee performance in Eskom Southern Region. In order to achieve this purpose a survey was undertaken (N=83) which measured perceptions regarding the existing organisational culture, preferred organisational culture as well as organisational commitment. Performance rating scores were linked to each respondent and were obtained from the performance management process of Eskom Southern Region. The main findings of this research can be summarised as follows: • The dominant existing organisational culture in Eskom Southern Region is the power culture, while the dominant preferred organisational culture is the achievement culture. • There is a significant organisational culture gap between the existing and the preferred organisational culture in Eskom Southern Region. • The dominant organisational commitment within Eskom Southern Region is affective commitment together with normative commitment. • The findings related to the employee performance include: o A slight but significant negative relationship was measured between the existing achievement culture and employee performance. o No significant relationships were measured between the preferred cultures and employee performance. o No significant relationships were measured between the organisational commitment scales and employee performance. • The findings pertaining to the relationship between organisational culture and organisational commitment can be stated as follows: o A significant positive linear relationship between the existing achievement culture and affective commitment was measured. A strong, significant negative linear relationship between the existing power culture and the affective commitment was also measured. o No significant relationships were measured between the preferred organisational cultures and organisational commitment. o The organisational culture gap has a significant effect on the organisational commitment of employees. • The findings pertaining to the relationship between the biographical variables and the organisational culture, organisational commitment and employee performance can be stated as follows: o There exists a strong significant relationship between the years of service and the existing organisational culture scales. o No significant relationships exist between the preferred organisational culture scales and any of the biographical variables. There was a common agreement across all respondents on the preferred organisational culture. o A significant relationship was found between organisational commitment and the number of people supervised. o A slight but significant positive linear relationship between the age of respondents and employee performance ratings was measured. It can therefore be concluded that the type of organisational culture has a significant impact on the level of affective commitment of the employees within Eskom Southern Region. No significant positive relationship was found between organisational commitment and organisational performance in Eskom Southern Region.

Full textAbstract:
Electricity supply industries (ESI) around the world are subject to structural and regulatory change. The environmental implications of these changes will depend, largely, on future investment within cleaner technologies. As developing countries (Des) increase levels of electricity supply, the incentives for investment in clean technologies is particularly important. Policy-makers wishing to promote renewable electricity technologies (RETs) in Des need to understand the nature of technological change in large technical systems (LTS). Broadly this thesis adopts the view that technological change is the outcome of the complex interaction of technical, economic and political factors. Initially technological change in LTS is shaped by social and political factors. As the system increases in both size and complexity driven by economies of scale and scope, and through co-evolution of technical and institutional features, it exhibits 'momentum,' whereupon technological change tends to be 'incremental' and autonomous. Through problem-solving activities to address 'reverse salients' the system evolves on a 'technological trajectory,' its path confined by technological and economic boundaries defined by the prevailing 'techno-economic' paradigm. Subsequently new technologies such as RETs, with characteristics different to those of the 'Traditional Electricity System Trajectory' (TEST) are unlikely to be favoured. Restructuring the electricity system provides a discontinuity in its momentum, allowing the drivers and interactions of different stakeholders to be more transparent. During such periods of instability there are important opportunities for systemic change through meaningful policy input. The socio-economic importance of electricity supply in Des further increases the 'technoinstitutional complexity' within the electricity system, and so resistance to restructuring. The thesis argues that restructuring of the ESI is a necessary, but not sufficient requirement for commercialisation of RETs. Rather policies supported by legislation should ensure that conservative techno-institutional mechanisms are replaced by ones that encourage a 'Balanced Electricity System Trajectory.' The BEST framework incorporates 'economies of the system' as a driver and is characterised by distributed technologies including small-scale and modular generation and sophisticated control technologies. As well as being characterised by flexible control in the technical sense, the BEST model is also characterised by flexible institutional arrangements.

This study analyses the relationship between electricity prices, consumption and economic growth at national and per sector levels in South Africa over the period from 2006 to 2017 using the auto-regressive distributed lag (ARDL) bounds testing approach and error correction model (ECM). With regards to electricity consumption, in the mining and residential sectors, the relationship between electricity consumption and GDP is insignificant and thus adheres to the neutrality hypothesis. In contrast, in the services, transportation and industrial sectors, there is a positive relationship between GDP and electricity consumption, which adheres to the conservative hypothesis. Lastly, the agricultural sector has a positive relationship between electricity consumption and economic growth in the short run, and thus adheres to the growth hypothesis. In the case of electricity prices and electricity consumption, the results find that the relationship is insignificant on a national basis and this is true for the services, transport, residential and agricultural sectors too, whereas there is a negative association with electricity consumption in the mining sector while the industrial sector has a negative association with electricity prices. The results for the relationship between electricity prices and electricity consumption show that in the national, services sector, transport sector, residential and agricultural sectors, electricity consumption has an insignificant relationship with the electricity prices. This is in contrast to the mining sector, whose electricity consumption is negatively associated with electricity prices while the industrial sector electricity consumption has a positive and significant relationship with electricity prices. With regards to the relationship between electricity prices and GDP, the results find that there is an elastic association in the national, services, mining, and industrial sectors with a negative impact on the GDP in the long run. In contrast, the relationship between electricity prices and GDP in the transport and residential sectors is insignificant.

Thesis (MDF)--Stellenbosch University, 2014.ENGLISH ABSTRACT: Coal export mines in the Mpumalanga Highveld region of South Africa generate growing volumes of discard coal estimated to be in excess of a billion tonnes. It presents a significant pollution hazard. Discard coal has a usable carbon content that can be used in the generation of power through the application of fluidized bed combustion technology. The objective of this study was to evaluate its potential as an economically viable fuel source for generation of electricity at the Witbank coalfields. This study was motivated by advances in fluidized combustion technology and significant changes in the South African electricity market in recent years. A holistic approach was adopted considering regulatory policy, market, technical, environmental and economic factors in the use of discard coal as an alternative fuel source. The policy and regulatory environment was assessed from the perspective of the private sector as project developer and the most likely source of funding, given government’s funding constraints. An evaluation of the future pricing structure of electricity, energy resource mix, demand growth, future development of the coal market, production of discard coal and the cost of coal was conducted. Levelised cost of electricity methodology was used to conduct the economic feasibility for comparison with the cost of Eskom’s pulverised coal technology for its new power stations. The study found that generating electricity from discard coal presents a significant commercial opportunity as its levelised cost of electricity was found to be lower than Eskom’s levelised cost of electricity for its new power stations. Plant sizes of 125 MW to 1 000 MW were considered. For plant capacities of about 500 MW and larger, the cost of electricity was found to be competitive with the current average electricity price taking into account the cost of transmission/distribution and interest charges. This is on condition that the electricity is sold to Eskom or wheeled through Eskom’s grid and sold to third parties. Otherwise, plant capacity will be limited to the maximum demand from large local users, which is expected to be considerably less than 500 MW. Currently there is no regulatory certainty on wheeling mechanisms and charges and it is an area where major policy development is required. The development of a project could be hampered by policy uncertainty and because of Eskom’s monopoly position as single buyer. The favourable results and findings of the economic evaluation conducted during this study warrant further detailed feasibility studies.

Thesis (MBA)--Stellenbosch University, 2002.ENGLISH ABSTRACT: The energy sector of the South African economy is poised to change in extraordinary ways. In just a few short years from now, the days will be gone when generators are guaranteed of their income and where regional distributors have the monopoly in the regions that they are servicing. Other energy markets in the world, such as oil and gas, have been free of regulation for many years. More recently, local policymakers have been focussing on increasing competition in the electricity sector and in so doing, liberate electric utilities from government's long established control. The shift away from government regulation of energy will lead to something even more important than placing downward pressure on the price of a MWh. It will instigate the development of multiple trading centres and platforms that are dedicated to competition in the free trade of electricity and related products. With the deregulation of the electricity supply industry and the inevitable introduction of competition, the real risks of energy trading will be faced by generators and distributors alike. This research investigates the changes that are set to occur within the next few years, based on developments that have unfolded in countries where electricity supply industries have been privatised and utilities and distributors are managing their risks in this new competitive environment. It explains how the South African Electricity Supply Industry may change with respect to the develop of markets which provide risk cover to industry players, the practices assumed by utilities in international electricity supply industries to minimise their risk exposure, and how industry players can use derivative instruments to manage their risks better.
AFRIKAANSE OPSOMMING: Die elektrisiteitsvoorsieningssektor is gereed om groot veranderings te maak. Binne 'n paar jaar, sal ons die einde sien van die dae waar kragstasies gewaarborg is van hulle inkomste en waar streeksvoorsieners die monopolie het in die streke waarin hulle verskaf. Ander energie markte in die wêreld, soos die van olie en natuurlike gas, is al sonder regulering vir baie jare. Meer onlangs het beleidsrade hul tyd toegewy aan die instelling van kompetisie in die elektrisiteitsvoorsieningssektor om utiliteitsmaatskappye vry te maak van staatsbeheer. Hierdie beweging weg van staatsbeheer sal lei na iets meer as net die afwaardse druk op die prys van 'n MWh. Dit sal die begin merk van die ontwikkeling van veelvoudige verhoë wat toegewyd is aan kompetisie in die vrye handel van elektrisiteit en soortgelyke produkte. Met die deregulering en die onvermydelike indiening van kompetisie, sal die ware risikos van energie handel aanvaar word deur voortbrengers en verskaffers van elektrisiteit. Hierdie navorsing stel ondersoek in die veranderings wat van plan is om te gebeur in die volgende paar jaar en is gebaseer op die ontwikkelinge wat in lande afgespeel het waar elektrisiteitsvoorsieningsnywerhede geprivatiseer is en waar voortbrengers en verskaffers van elektrisiteit hulle risikos bestuur in hierdie nuwe mededingende sektor. Dit verduidelik hoe die Suid-Afrikaanse elektrisiteitsvoorsieningsnywerheid mag verander teen opsigte van die ontwikkeling van markte wat risiko versekering aanbied vir utiliteitsmaatskappye, die praktyke wat deur hierdie spelers toegepas word om hulle blootstelling aan risikos te verminder, en ook hoe hulle afgeleide instrumente gebruik om hulle risikos beter te bestuur.

Thesis (MPhil)--Stellenbosch University, 2008.Towards the end of 2007, South Africa started experiencing widespread rolling electricity blackouts as the electricity demand exceeded the supply from energy giant Eskom. The crisis reached its tipping point when industries, including Sasol, were requested to reduce their electricity consumption by 10%. The purpose of this research was to identify alternative futures for Sasol in the light of the current electricity crisis. The scenario process was used to develop the following independent scenarios for Sasol: • Fuel to the fire. The country is amidst an ongoing nationwide electricity crisis and Sasol is still dependent on Eskom for more than 50% of its electricity demand. The end result is reduced turnover, shortage of liquid fuels and a decrease in Sasol’s contribution to the economy. • Ignorance is bliss. This is a world where Sasol is independent of Eskom for electricity supply despite the country’s continuing electricity crisis. Independence is ideal but unfortunately it comes at a cost. It is about taking painful action in the near term to forestall even more painful consequences in the future. • Blessing in disguise. Sasol is dependent on Eskom for the majority of its electricity requirement. The reliability of electricity supply in South Africa recovered and there is an overall awareness regarding energy efficiency and a positive adoption of alternative energy technologies. • Icing on the cake. Sasol is completely independent of Eskom and Eskom managed to restore the integrity of electricity supply. The end result, Sasol can continue with its planned growth and expansion. In order for the scenarios to be useful for Sasol, it is necessary to incorporate them into the strategic agenda. Some considerations include the gradual replacement of traditional fossil fuels, carbon capture and sequestration, advanced coal electricity generation (clean coal technology), increasing the use of renewable energy sources and developing the hydrogen economy.

Racially discriminatory apartheid-era policies, population growth, and high unemployment have given South Africa a severe shortage of urban low-income housing. This thesis evaluates the sites and services approach as a means to reduce the housing shortage. The limited success of the new democratic government's efforts to provide the urban poor with formal low-income housing suggests that sites and services housing's reliance on self-help labor may reduce the housing shortage more effectively than formal housing. This study will assess the sites and services approach in terms of several basic factors. They include: government costs per housing unit, speed of construction, affordability for the poor, and the degree to which the method can produce a standard of housing that could be acceptable to the poor.Master of Science

Thesis (MBA) --University of Limpopo, 2010Management of electricity usage by household plays an important role in the growth of the country’s economy, and the avoidance of load shedding from Eskom. Electricity usage is very important for the growth of the economy and creation of job opportunities. The management of electricity usage by household’s customers will play a very critical role in the growth of the country’s economy and the creation of jobs. The contribution of households in applying the electricity saving techniques will reduce the risk of load shedding from Eskom during summer and winter. The save usage of electricity will give Eskom enough chance to build power stations to keep up with the demands and the growth of the South African economy. For the household customers to contribute positively, Eskom and the municipalities should conduct road shows to educate customers about the save usage of electrical appliances and the saving techniques that can be applied by households. Customer awareness campaigns should be conducted in both rural, urban and semi-urban areas. It will be very important for Eskom to communicate with the municipalities to run the awareness campaigns in the urban areas due to the high demand of electricity by households coming from the urban areas. The majority of households who are using the high consuming appliances of electricity reside in the urban areas and can play a vital role in minimizing the risk of load shedding that affected the country negatively in 2008. The quantitative research method was followed for this research. A questionnaire was used to collect the data from the household’s participants. Forty households from the five areas of Polokwane took part in the research totalling 200 participants. It was discovered that the customer awareness campaigns were conducted by Eskom in the areas where they service customers, although there are some gaps in other areas where the customers are complaining about lack of road shows to teach households about the electricity saving tips. Municipalities in all the five areas of Polokwane where the research was conducted are still lagging behind with the customer’s awareness campaigns. However Eskom customer services and the municipalities can work together and conduct road shows to reach more customers in order to reduce the risk of load shedding and power interruptions.

Thesis (MComm (Economics)--Nelson Mandela Metropolitan University, 2011.ENGLISH ABSTRACT: Renewable energy technology has received much attention over recent years. The depletion of known fossil fuel reserves and the volatility of international fuel prices require that society looks beyond the current coal-dominated electricity generation methods. Wind energy is an internationally well-established technology with large markets in major countries around the world, such as the USA and Germany. South Africa has the potential to generate large amounts of electricity from the wind because of the strength of the country’s wind resource. The long coast line and open areas are ideal for the exploitation of wind energy.

Full textAbstract:
South African electricity tariffs were relatively low compared to the rest of the world. The average South African business has for long taken this advantage for granted and is now surprised to realise that electricity is becoming an expensive and scarce commodity. The South African electricity supply industry is far more complex than the average person may think. The infrastructure supporting this industry is extremely costly; takes long to develop and build and requires careful planning and management. There are many sources of energy and many technologies for generating electricity. However, many of these do not appear quite ready to serve the needs of the industry. The manufacturing industry depends heavily on electricity. The recent power outages and tariff increases have served as a cruel reminder of this fact. The automotive sector has lost many days of production and the increasing electricity costs erode the profitability of the affected companies. The automotive suppliers and vehicle manufacturers have expressed their concerns. Indications are that some have reduced the number of employees and may even face bankruptcy. This research aims to gain the perspective of senior managers in the automotive industry regarding the impact of the increased electricity tariffs on their manufacturing costs. Naturally, all electricity consumers will be affected by this. However, this research aims to investigate the significance of the effect on the automotive industry as well as obtain some indication of which factors determine the level of dependency. Each company has to react strategically to the situation and apply those measures which are available to them. This research determines how strongly the industry feels about reacting and which strategic measures they will apply. The outcome is descriptive of the circumstances in the industry and indisputably serves as an indication of the financial impact of electricity tariff increases.

Full textAbstract:
The economic boom in South Africa following the 1994 democratisation led to increased welfare of the citizens and their purchasing power. This further resulted in increase in electricity consumption. The electricity supply did not increase proportionally to the increase in electricity consumption leading to the 2008 shortage of electricity which nearly damaged the power generating circuit. The literature review has shown that electricity supply and consumption have a positive impact on economic growth. It further showed that employment enhances economic growth. Conversely, it showed that power outages negatively affect economic growth. The research serves to investigate the relationship between electricity supply and economic growth in South Africa and to examine the impact of power outages on economic growth. It also seeks to find the appropriate structure for electricity supply industry that will lead to increase in economic growth. The autoregressive distributed lag (ARDL) bounds approach was used to find the relationship between economic growth, electricity supply, power outages and employment using quarterly data from 2000 to 2012. The ARDL technique was chosen over the conventional models such as Johansen technique for the research because it uses a single reduced form of equation to examine the long run relationship of the variables as opposed to the conventional Johansen test that employs a system of equations. The ARDL technique is also suitable to use to test co-integration when a small sample data is used and does not require the underlying variables to be integrated of similar order. The Vector Error Correction Model (VECM) Granger causality was also employed in the study to establish the causality between economic growth and electricity supply. It was chosen for its ability to develop longer term forecasting, when dealing with an unconstrained model. The results from the ARDL bounds test showed that there is a long run relationship between economic growth, electricity supply, power outages and employment. Based on the causality tests, the findings showed a unidirectional causality flowing from electricity supply to economic growth. This implies that electricity supply affect economic growth in South Africa. The results further showed no causality flowing from economic growth to electricity supply which indicates that when economic growth is booming fewer funds are used for improvement of the electricity generation. Lastly, the results showed that power outages negatively affect economic growth in the long run. To sum up, electricity supply is an important factor for economic growth in South Africa. It is therefore necessary that South Africa must put in place measures aimed at stimulating electricity supply. One of the measures aimed at increasing output of electricity is to unbundle the electricity sector. This process involves allowing entry of the Independent Power Producers (IPPs), Independent System Operator (ISO) and Regional Electricity Distributors (REDs). This will lead to increased supply of electricity and competitively lower prices of electricity. The study further recommends that renewable energy sources should be used to produce electricity instead of coal and nuclear fuels as they failed to produce enough electricity for the nation.

Tito Mboweni (2011) said one of South Africa’s biggest tests is the overwhelming the skills shortage. He was echoing the views of Higher Education Minister Blade Nzimande who himself said “South Africa could not afford to have an economy "constrained by a severe lack of skills". There are numerous initiatives that having been undertaken by government in an attempt to solve the skills shortage problem. However, these initiatives are not aimed at the tertiary education system. The tertiary education system is the focus of this study as the author investigates how the NMMU Business School can play a significant role in addressing the skills shortage in the credit risk management sector. Following a literature review, surveys were completed by the NMMU Business School MBA students (ninety of them completed it) and personal interviews were conducted with three Provincial HR managers from South Africa’s “four big banks” in Nelson Mandela Bay (Nedbank, Standard Bank and ABSA). The study found that the skills shortage is indeed a problem. The study found that reasons including the legacy left by apartheid and students pursuing the wrong degrees were highlighted as some of the reason for this skills shortage. An opportunity for the NMMU Business School was identified to support the banking industry in addressing credit risk management skills shortage. The benefits include financial reward and more importantly an opportunity to differentiate the Business School and the courses offered at the school from the rest. Some of the recommendations included sourcing of the best practices from institutions like the Millpark Business School on effective partnering with the banking industry as well as a proactive approach to be adopted by the banking industry in terms of lobbying support from other potential role players for example but not limited to, student bodies, BankSeta and the smaller banks in the industry.

The study was premised on the truism that men have historically served in higher echelons of organizational management structures and women are under-represented. The principal objective was to explore the constraints faced by women in accessing higher leadership and senior management positions in public, private and non-governmental organisations in Zimbabwe. This study adopted the triangulation method, that is, qualitative and quantitative approaches. These mixed research methods, were upgraded by the feminist research methodologies, thereby making a contribution in the field of research. The study found out that the constraints that mostly hinder women from accessing leadership and senior management positions in public, private and NGOs were cultural practices, which represent levels of power and control that in turn hinder reforms; and women's socialisation into feminised roles. The study also found out that in most organisations, most females work under male leadership, and this traditional organisational culture, needs to be deconstructed and reversed in order to achieve gender equality. The study recommended for a human centric and integrated organizational management strategy for public, private and NGOs in Zimbabwe. The adoption of a human centric and integrated management approach should aim at gender equity and reduce women's under-representation. A human centred organizational culture has to be practiced, that would create organisational ethos that guide organizational management. An integrated organizational management approach should integrate all systems and processes into one complete framework, enabling people to work as a single unit, unified by organizational goals, shared vision and common values. The system should depend on a balanced mix of the masculine and feminine attributes. The approach should put its weight towards adoption of measures to attract, advance and empower women so as to benefit from their qualifications, experience and talent in a highly competitive environment.

Thesis (MBA)--Stellenbosch University, 2014.The government of South Africa aspires to achieve a six percent economic growth per annum. The scarcity of qualified and experienced people that are crucial in contributing to economic growth and creating job opportunities, poses a problem for the country. The current demand for skills that are out of reach for many workers and the prevailing unemployment that is caused by the mismatch between what an organisation seeks and what a potential candidate can provide, have been highlighted as a critical cause for the scarcity of skills. The aim of this research assignment was to examine the current crisis of the skills shortage in the South African economy, with the focus on the manufacturing sector within the FMCG industry. Semi-structured and open-ended interviews with human resource, training and development, as well as technical managers in manufacturing organisations in Cape Town, South Africa were conducted. Data was obtained from a sample of six managers. According to all respondents interviewed, it takes approximately two to six months to replace an employee who has the appropriate technical skills. All the respondents are concerned with the situation of the technical skills shortage in the country. Consequently, these respondents’ companies engage in a talent war in order to recruit the best talent. It is therefore obvious that the market dynamics of supply and demand are out of equilibrium with regard to technically skilled employees in the manufacturing segment of the South African FMCG industry. The interviews that were conducted identified some companies that train new employees in technical skills. However, the majority of the companies are not doing much to improve the situation. In addition, the companies in this sector also compete with the other industries in the South African and the global economy regarding technical skills.

At the start of 2010, the National Energy Regulator of South Africa (NERSA) announced that electricity tariffs would increase at an average rate of 25 percent per year over a three year period (Njobeni, 2010). This raised fears within the economy and specifically within the agricultural sector that these increases would negatively impact the agricultural sector. Various stakeholders within the agricultural sector also raised opinions on what the true impact will be on agricultural production and market prices. The main objective of this study was to quantify the true impact of higher electricity tariffs on production and market prices within the potato industry. The study focused on the potato producing regions of the Sandveld, Limpopo and South Western Free State. On-farm data were collected in an attempt to capture the electricity consumption and costs associated with potato farming in these specific regions. An effort was also made to calculate and capture production costs in these three regions which, together with the collected electricity costs, formed the basis of the analysis. The study applied a supply response model developed by the Bureau for Food and Agricultural Policy to evaluate the impact of increased electricity tariffs on potato production and prices in South Africa. The supply response model used is a standard econometric recursive dynamic model that has the purpose to model policy analysis, iv with short, medium and long term projections on an annual baseline basis (van Tongeren et al, 2000). However, in order to conduct analysis on electricity tariff increases, this supply response model required adaptation and improvement in order to incorporate electricity costs. Before this adjustment, the model applied the producer price / fertilizer price ratio as a proxy for production costs. Since detailed production costs (including electricity costs) were acquired through this study it was now possible to alter this ratio to a producer price / production costs ratio which included the electricity costs. To illustrate the impact of the electricity price increase the electricity cost component in production cost was shocked to reflect an increase at the set rate of an average of 25 percent per annum for the 2010, 2011 and 2012 production years. The results demonstrated that these three regions will see a decrease in hectares planted over the period between 2013 and 2020 as a result of the increased electricity tariffs, but that this decrease in hectares planted will be very small. The Sandveld region had the highest impact as it was calculated that on average, over the period between 2013 and 2020, a total of 35 hectares of potato production will be lost due to this higher electricity tariff. It can further be expected that the market price in the Sandveld region would increase slightly by 52c/10kg over the same period. The South Western Free State region was least effected by the higher electricity tariffs as a mere 1.6 hectares of potato production land could be lost due to the higher electricity tariffs which will lead to an increase of around 36c/10kg in market prices over the period between 2013 and 2020. The study further introduced a cost saving technique that farmers can use to counter the higher electricity tariffs. The majority of farmers consume electricity under the Landrate and Ruraflex tariff structure. It is this Ruraflex tariff structure that farmers can use to their advantage by consuming electricity during specific periods of the day that would result in a lower c/kWh cost. By reviewing the irrigation scheduling and activities of farmers the study established that most farmers pay far too much for electricity since their peak usage are during the periods of the day where higher rates apply. The study calculated that farmers, by applying this technique, could save between R190 and R455 on electricity costs per hectare in the Sandveld region. The study concluded that the impact of higher electricity tariffs on potato production and market prices in the Sandveld, Limpopo and South Western Free State regions are of a small nature which will most likely be absorbed by the farmers. The claims by various industry participants that the potato industry would be adversely negatively impacted were unfounded in this study. Nevertheless, in the event that electricity tariffs continue to increase in the future, farmers have to their disposal a cost saving technique that will aid them in countering some of the negative effects of electricity price hikes.Dissertation (MCom)--University of Pretoria, 2012.

Thesis (MBA)--University of Stellenbosch, 2010.Climate change is one of the most serious issues the world is facing today. With an economic slowdown globally, huge food shortages and record-high fuel prices, it has never been so important for countries to guard their natural resources to ensure future sustainability. The South African energy generation industry, of approximately 40 000 Mega Watt (MW), consists largely (90%) of coal-fired power stations, with the remainder comprising of nuclear and pumped storage schemes which are regarded as environmentally neutral. It is only recently that Eskom and independent power producers (e.g. Darling Independent Power Producer Wind farm with an estimated 10 MW) embarked on utilising South Africa's natural resources to generate electrical power. South Africa's access to inexpensive coal and paid off coal-fired power stations has made it difficult to justify the investment in renewable energy. However, on 31 March 2009 South Africa became the first African country to introduce a feed-in-tariff for renewable energy (Gipe, 2009). The hope is that this initiative would stimulate the investment in green energy generation. Eskom and municipalities are currently the only entities that have licences from the National Energy Regulator of South Africa (NERSA) to buy bulk electricity from power producers. The question therefore arises: if green electricity is more expensive to generate and is sold at a price premium to Eskom and municipalities, would they pass the premium on to consumers; can they differentiate the green electricity product and will consumers be willing to buy at a premium price? This research study aims to answer if businesses would be willing to pay a premium for green electricity, why they would be willing to buy it, which factors influence the purchasing decision and what barriers exist that will deter a purchase. A survey was conducted on businesses in the Western and Northern Cape of South Africa. The businesses sampled have a notified maximum demand of 50kVA or higher and excludes the re-distributor (City of Cape Town) customers. Approximately ten per cent of businesses would be willing buy green electricity. Most of these businesses have indicated that they are willing to pay a premium of five to nine per cent for green electricity. The businesses that are willing to pay the largest premiums (>10%) are in the electricity, gas, water, finance, insurance, real estate, business services, manufacturing, transport, storage and communications sector. Businesses that are willing to buy green electricity: • Have a strategy to reduce their carbon footprint; • Want to be community leaders (altruistic motivators); • Have as their biggest barrier the additional cost of green electricity; and • Feel that power utilities should be required to include a minimum percentage of green energy in their energy mix.

At the beginning of 2008, South Africa faced its most severe electricity supply crisis to date. The crisis led to a severe contraction of mining industry output and had a knock on effect on the rest of the economy. This dissertation aimed to explore how such a crisis could occur in a South Africa, when in the years leading up to the crisis, the state owned electricity utility, Eskom, had won awards as one of the lowest cost, most efficient and technologically innovative electricity companies internationally. In order to explore this, the method of the analytic narrative was used, this was supported by process tracing that identified the key period of research as the years 1998- 2004. The paper explored themes of administrative complexity, competing stakeholders and multiple objectives. It was found that the crisis could be credibly explained as having stemmed from the interaction of complex power relations across the public service in a climate of unresolved political conflict and time sensitive decision making.

Full textAbstract:
A key economic issue for government is the ability to effectively match electricity supply to electricity demand, because of the substantial economic losses in the case of where there is too little supply, or the waste of scarce resources where there is too much supply. In the case of South Africa, this issue, the importance of which was highlighted by the power shortages and associated “rolling blackouts” experience in 2008, has led to the creation of the Integrated Resource Plan (IRP) as a means to decide how energy policy will be developed. Recently, however, the IRP 2010 and its subsequent 2013 and 2016 (draft) updates have been criticised as being too optimistic in regards to their projections of economic growth and electricity demand, making the recommendations in these documents to be flawed. Using monthly data from January 1990 to May 2017, together with Autoregressive Distributed Lag (ARDL) bounds testing for cointegration, this paper measures changes in the elasticity of electricity demand as a result of the massive price hikes over the past decade. Thereafter, the implications of changed electricity as well as possibly lower Gross Domestic Product (GDP) growth in the future for forecasts of possible future demand for electricity are examined. From these revised forecasts, it is possible to make appropriate recommendations in regards to electricity supply policy for South Africa including what possible energy mix is needed as well as the requirements for creating new supply to meet possible future demand. It is concluded that future electricity demand is likely to be much lower than forecast in the IRP 2010 and IRP 2013 documents. The degree of uncertainty in electricity demand growth suggests that large-scale increases in supply capacity taking years to construct, such as coal or nuclear, should be avoided. Small, incremental increases in supply that are able to come on stream swiftly, such as gas, solar and wind power, are likely to be more appropriate for meeting South Africa’s future needs.

Full textAbstract:
This study concentrates specificaUy on assessing those elements of private and external costs and benefits which need to be accounted for in analyzing the role of electricity supply in a developing region. To facilitate this aim, three interrelated questions are addressed. The first question examines the reasons why a critical need for electrification in developing areas exists. In this regard, a selective review of the literature on development economics is offered, illuminating the previous neglect of the rural dimension in development and the associated problems of poverty and inequality, a lack of infrastructure and the general inability to fulfill basic needs. The second question is devoted exclusively to an economic analysis of the supply of electricity in developing areas. A broad theoretical review on whether an unregulated or regulated (private or public) sector should be responsible for the provision of electrification is presented. This evaluation highlights the various welfare implications and efficiency considerations that appear to be relevant in the present context. The final question, which constitutes the central proposition of the thesis, establishes how electrification should be supplied in developing areas. To this end, the conditions specific to a region in Venda are discussed. An attempt is made to identify the private and external costs and benefits relating to electricity supply and the corresponding costs and benefits pertaining to alternative sources of energy. Since the incidence and nature of these costs and benefits could only be ascertained from individual households, it was deemed necessary to undertake a questionnaire study of residents in Makwarela township and its periurban settlement of Lufule-Tshisele. A number of basic trends were evident from the research results. As far as the various benefits are concerned, respondents tended to place a much higher value on both the private and external benefits associated with electricity than its alternatives. At the same time, the survey found that although the private (or monetary) cost of electricity far exceeded the corresponding cost of alternative energy sources, the external costs were significant in the case of alternative energy sources, but virtually non-existent in the case of electricity. On the whole, the Venda survey seems to suggest that an economic case can be made for involving the broader community in subsidising the supply of electricity in Makwarela, Lufule-Tshisele and other areas. While such a subsidy can perhaps be justified on distribution grounds alone, and more specifically in terms of the rapid and pronounced effect it is likely to have on the quality of life in the region, its real worth lies in the fact that it may confer certain external benefits on the community.

Bibliography: pages 163-172.This study examines the involvement of public and private sector institutions in the provision of electricity in urban areas of South Africa. Access to electricity in South Africa is highly unequal and little progress is currently being made to bring electricity to all, mainly due to institutional and financial problems. The focus on public and private sector roles is adopted because of the social importance and economic nature of electricity provision, the global and national significance of privatisation policies, and the current importance of allocating appropriate roles to the public and private sectors in widening access to services, including electricity, in South Africa. The distribution sector of the South African electricity supply industry (ESI) is highly fragmented. Municipal electricity departments, which mostly serve white residential, commercial and industrial areas, are generally highly profitable and provide an effective service, but are not highly efficient by international standards. These departments are self-sufficient in the implementation of electrification projects, and have access to adequate capital to finance such projects. Electricity distribution authorities set up to serve black areas, especially electricity departments of black local authorities, are ineffective, and often financially unsound. Due to the weakness of public authorities charged with the task of undertaking electrification projects in black areas, the implementation of these projects is dependent on the involvement of private electrical consultants and contractors. However, few such projects are currently being undertaken due to inappropriate planning and shortages of concessionary finance. After close consideration of the benefits and drawbacks of public and private involvement in range of activities that arise from electricity provision, it is concluded that the key challenges facing the ESI in South Africa will best be met if the distribution sector is restructured on a regional basis in order to utilise existing expertise, and retained within the public sector. Accelerated electrification initiatives, planned and co-ordinated by these distribution authorities, would draw upon the experience and capabilities of private electrical consultants and contractors. Public sector leadership in mobilising both public and private investment would also be necessary. Thus, whilst public institutions would be dominant, important roles would remain for the private sector in the provision of electricity in urban areas. The results of this study suggest that far from privatising service provision in South Africa, it will be essential to allocate a dominant role to the public sector in widening access to services to all.

Thesis (Mathematics) -- University of Limpopo, 2010Forecasting electricity consumption is a challenge for most power utilities. In South Africa the anxiety posed by electricity supply disruption is a cause for concern in sustainable energy planning. Accurate forecasting of future electricity consumption has been identified as an essential input to this planning process. Forecasting electricity consumption has been widely researched and several methodologies suggested. However, various methods that have been proposed by a number of researchers are dependent on environment and market factors related to the scope of work under study making portability a challenge. The aim of this study is to investigate models to forecast short term electricity consumption for operational use and medium term electricity consumption for tactical use in the Ferrochrome sector in South Africa. An Autoregressive Moving Average method is suggested as an appropriate tool for operational planning. The Holt-Winter Linear seasonal smoothing method is suggested for tactical planning.

This paper investigates the details behind aggregate shifts in household electricity access in South Africa. More specifically, when viewed from a cross-sectional perspective, we note a significant (and surprising) decline in electricity access between 2008 and 2010, followed by a substantial improvement in access between 2010 and 2012. In order to further investigate these interesting dynamics and move beyond a limited cross-sectional analysis, we then set up the National Income Dynamics Study (NIDS) in a novel form that allows one to track household units in a longitudinal fashion. Using this data, we identify the initial drop in electricity access to have come as a result of a large number of household disconnections, as well as a significant degree of "misdirected" household formation (with people leaving household with access and setting up households in locations without access). We also identify the subsequent improvement in aggregate access to have come primarily as a result of a significant fall in the number of households that lose access over the period, an increase in the number of households that gain access, and favourable household formation processes (with people leaving households without access and moving into households with access). It is therefore vital that those involved in coordinating service delivery take into account that, if one's aim is to improve aggregate electricity access, preventing loss of access is just as important as expanding access. Policy makers should also take note of household formation and dissolution processes when considering service delivery expansion - to prevent government from needlessly chasing a moving target.

2012This research focused on investigating perceptions of the socio economic impact of skills shortage on the community of Khayelitsha, Western Cape. The objectives of this study were to critically investigate the causes of skills shortage in the community of Khayelitsha; to assess the perceived social impacts that it has on the community; and to critically investigate whether skills shortage is one of the causes of unemployment. The research also went as far as examining measures, which were taken by government and other stakeholders to address skills shortage. Chapter One of the study provides information related to a background of the research under study. Chapter Two briefly considers skills shortage, globally, prior to looking thoroughly at the causes for skills shortage in Khayelitsha. It further presents evidence of skills shortage in South Africa by considering different sectors. Furthermore, the research details the social and the economic impact of skills shortage, the state of poverty and inequality, as well as the state of unemployment. Chapter Two also details the role of government and other stakeholders to address skill shortage. Chapter Three introduces the research design and methodologies that were used, while Chapter Four presents an analysis and assessment of data that was collected. Chapter Five concludes the research by making recommendations. Two types of methodologies were employed by the researcher, namely qualitative and quantitative research methodology. The researcher employed two types of data analysis, namely content analysis and descriptive statistics. These techniques were helpful for the study because they explored perceptions and evidence of skills shortage in South Africa and Khayelitsha, in particular. The study further explores the impact of skills shortage on the economic development of the country, unemployment poverty and the society at large. Finally, the research shows that respondents perceive that skills shortage does indeed have a negative impact on South Africa by being one of the causes of unemployment and poverty, and hence economic growth. While socially, respondents believe that skills shortage is the main driver of issues such as crime, violence, teenage pregnancy, prostitution, HIV/AIDS poverty and other social issues, which are prevalent nationwide.

Absenteeism can be a major problem for organisations. As pressures increase on the budgets and competitiveness of companies, more attention is being given to reduce workplace absenteeism and its cost. Job satisfaction has been noted as one of the factors influencing an employee's motivation to attend. Studies on the relationship between absenteeism and job satisfaction seem to be inconsistent. Some research has found no correlation between these two variables whereas other studies indicate a weak to moderate relationship between these two variables. The aim of this study was to determine whether there is a relationship between job satisfaction and absenteeism in a selected department within and Electricity Unit in the Western Cape.

Full textAbstract:
Thesis (PhD (Electrical Engineering))--Cape Peninsula University of Technology, 2019As far back as 2008 the demand for electricity in South Africa (SA) has exceeded the supply of electricity (Joffe, 2012). Electricity generation in SA is a monopolistic industry driven by Eskom with most of its electricity generated by large coal-fired plants and one nuclear plant. This is in line with most countries where electricity is generated by these large power-generating plants and then transmitted via high voltage transmission systems. This situation in SA however came to a head during 2008 with a power crisis which the majority of South Africans will not easily forget. This crisis shook the South African nation and at the same time made the consumers realise that they can no longer rely on Eskom as a sole supplier of electricity and that they, the consumer will have to invest in ways to alleviate this crisis. The months of blackouts reminded every consumer how important it is to have access to electricity. Since 2008, the electricity provision in SA has seen some changes but in spite of these changes SA’s power system remains under huge strain and will continue to be under strain until Eskom manage to complete and add their latest two large power stations, Medupi and Kusile to their network to deliver the capacity needed to relieve the shortage of supply. Recovering from the effect that the 2008 crisis had on the South African industries and the public as a whole is without doubt the most pressing and immediate challenge for South Africans. As this is to the long term prospects for the economy a secure supply of electricity is essential. This will have to be done at a cost which South Africans can afford if the economy is to sustain better and faster rates of investment and economic growth whilst providing access to electricity for all. It is therefore absolutely critical that the dependence on Eskom as a sole supplier of electricity should diminish. The South African government and policymakers will, therefore, need to consider measures on how to transform Eskom to allow its current grid to integrate alternate power generation sources such as renewable energy to open up opportunities for independent power producers (IPPs) to compete and stabilise the country’s electricity supply market. In addition to the inputs from the South African government and the policymakers South African industries and potential power generators will have to expand the energy supply mix in SA. This is important if the industry is committed to addressing the challenges of climate change. New players in the energy generation fields will have to be brought in together with new investors, technology and skills. One of the biggest challenges is to convince the South African government that an energy generation monopoly is no longer sustainable and that an energy generation mix can be perhaps more sustainable, reliable and “cleaner” if the right balance between IPPs and SA’s monopoly energy generator is carefully orchestrated and properly governed. Affordable cost structures will attract investments from IPP’s and have already started doing so. Fin24 (Lameez Omarjee (Fin24), 2019) reported that South Africa’s Energy Minister Jeff Radebe explained; “The National Energy Regulator of SA (Nersa) issues a licence to all IPPs, based on a full disclosure of information required, tariff and tariff escalation. A public participation process also takes pace to scrutinise the tariff before a licence is granted, before Eskom signs purchase power agreements (PPAs), Nersa will issue an approval for Eskom to enter into PPAs and confirm in writing that Eskom will be allowed the full associated cost under the cost recovery mechanism. Radebe further stated that the cost of buying energy from IPPs through purchase power agreements (PPAs) was included as expenditure, before the calculation of Eskom's operating profit” (Appendix A provides more insight). With the many renewable energy resources being developed, distributed power generation is an alternative way of diversifying the energy mix to satisfy most of the above requirements. The challenge here is how South Africans ensure that distributed power generation as an integrated energy mix between existing generation and new renewable energy generating resources are optimally utilised. In light of the growing global population which is driving an even greater increase in the demand for electricity and governments around the world focusing on reducing carbon dioxide (CO2) emissions by increasing the utilization of renewable energy sources in the power, chain seems to be the ultimate answer. In addition, these complex challenges are indeed driving the evolution of smart grid (SG) technologies which come with a whole host of new challenges and questions that needs to be answered. One of the most important challenges and questions to be answered is how effective communication systems will be deployed within smart grids (SGs) that will have highly efficient, fast very reliable and very secure characteristics to transmit and respond to any type of fault conditions which may occur within SG’s. There are many wireless technologies available such as Cognitive Radio Networks (CRNs), 3rd Generation Partnership Project (3GPP) release, Universal Mobile Telecommunications System (UMTS) and Long-Term Evolution (LTE) etc. Cognitive radios are intelligent software-defined radios (SDRs) that efficiently utilize the unused regions of the frequency spectrum, to achieve higher data rates. The CRNs however is an unlicensed technology which suffers from lower Quality of Service (QoS) (Ekström, 2009) and high latency problems. LTE and 3GPP releases is a promising licensed technology which addresses issues of QoS and latency, one of the technologies which can address all these issues (Patel et al., 2016). The potential of utilising existing LTE networks could reduce the cost of operation and expansion during the introduction phase of SG deployment in SA. Some work is available in literature to ascertain the viability of LTE as a communication technology for SG applications (Peng Cheng et al., 2011). For the purpose of this thesis, different communication networks will be studied, compared and modelled to determine their suitability for deployment within SG’s for rural areas in South Africa. In this thesis, the work is done mostly on communication technologies that can automate and manage the increased degree of complexity when the present grid system will be replaced by a smart grid. The digital technology that will allow a swift communication between the user and the utility, along with sensing along the transmission lines. The research considered smart metering, different interruptions, power outage and disturbances as a type of call that might originate in smart grids. These calls are handled using cognitive radio networks first and which are replaced by LTE networks due to the problem of license in cognitive radio networks.

Thesis (MBA (Business Management)) -- University of Stellenbosch, 2009.AFRIKAANSE OPSOMMING: Hierdie navorsingstudie het ’n telefoniese vraelys behels wat aan die einde van 2007 deur 405 respondente voltooi is. Die doel van die vraelys was om die opinies van ’n verteenwoordigende steekproef Kaapstadse residensiële elektrisiteitsverbruikers te bepaal ten opsigte van kwessies wat verband hou met die opwekking, verkoop en gebruik van hernubare of groen elektrisiteit. Dit is gedoen ten einde ’n ingeligte formulering te kan doen van toepaslike groen elektrisiteitsprodukte vir verkoop aan die residensiële elektrisiteitsmark. Response is op Likert-skale aangedui en is geanaliseer deur middel van nie-parametriese statistiese metodologie. Daar is bevind dat ’n groot proporsie (90.6 persent) van die Kaapstadse verbruikers bewus is van en besorg is oor die huidige klimaats- en omgewingsuitdagings en dat ’n soortgelyke proporsie (86.9 persent) bekommerd is oor die gevaar van aardse verwarming. Daar is ook bevind dat 85.0 persent van respondente gebruik maak van energiebesparende gloeilampies. Daar kon egter geen beduidende verwantskappe gevind word tussen die algemeen-aanvaarbare groener tegnologieë en die verbruikers se bereidheid om meer te betaal vir groen elektrisiteit nie. Daar is bevind dat 61.7 persent van die respondente bereid sou wees om tot 15.4 persent as ’n premie te betaal ten einde groen elektrisiteit te koop. Daar is verder bevind dat van die drie voorgestelde aankoopmetodes, groen notas (green tags) of groen kwitansies vir voorafbetaalde elektrisiteit die mees praktiese is en waarskynlik die mees algemeen aanvaar sal word. Verbruikers verkies om elke keer wat hulle elektrisiteit koop die keuse te kan uitoefen tussen groen elektrisiteit en konvensionele krag en dan is die voorafbetaalde manier van koop die mees geskikte opsie om die aankoop van groen elektrisiteit te bestuur. ENGLISH ABSTRACT: This study comprised of a telephonic questionnaire conducted in late 2007 with 405 respondents. The aim of the questionnaire was to derive the opinions of a representative sample of Cape Town’s residential electricity consumers on matters relating to the generation, sale and use of renewable or green electricity. This was done in order to inform the formulation of appropriate green electricity products for sale into the residential electricity market. Responses were noted on Likert scales and were analysed using nonparametric statistical methodology. It was found that a high proportion (90.6 per cent) of the Capetonian consumers were concerned about the environment and a similarly highly number (86.9 per cent) are concerned about the environmental challenges that are currently faced as a result of global warming. It was found that 85.0 per cent of households in the respondent population currently make use of energy-saving light bulbs. However no significant links could be found between the use of generally-accepted greener technologies and the consumers’ willingness to pay more for green electricity. It was found that 61.7 per cent of the respondents were willing to spend an average of 15.4 per cent more as a premium in order to buy green electricity. It was further found that of the three purchasing methods suggested that green tags, or green receipts for pre-paid electricity were the most practical and the most likely to be widely accepted. Consumers preferred the option of choosing at every purchase whether they opt for green electricity or conventional power and this would be most easily managed via a pre-paid receipt system.

The electric power policies in Nigeria and South Africa are considered the governments’ intention to provide quality and affordable electricity to the people. A comparative study on the electric power policies focuses on the similarities and differences in the policy approaches, the policy issues that affect electrification, and the impact of the policy issues in achieving the goal of universal access to quality and affordable electricity power in both countries. The methodological approach allows for an in depth textual study on the electric power policy documents in both countries. In Nigeria, the government intends to address the massive demand-supply imbalance and achieve the goal of electrification through reforms that focus on private sector-led growth in the sub-sector. In South Africa, the identification of electrification as a public problem by the post apartheid government leads to an integrated policy framework that focuses on balancing economic concerns with social and environmental considerations. The study identifies electricity provision as a social welfare responsibility of the governments in both countries and examines the policy issues in the context of public welfare. In Nigeria, the policy issues are found to be self serving and not in line with sustainable public interest, given the socio-economic challenges. As a result they, exert less impact on achieving the goal of universal access to quality and affordable electricity in the country. In South Africa, good governance in the sub-sector has enabled the identification of policy issues in line with sustainable public interests of social equity, poverty alleviation and environmental sustainability; and government using public administration agencies to play a key role in service delivery. Recommendations of the study mainly derive from the South African experience on electrification, and are intended to offer some policy-lessons to Nigeria in the sub-sector. The study contributes to new knowledge in the discipline of public administration by opening up new vistas for a comparative analysis of electric power policy issues in both countries in the context of public welfare. Besides, a comparative study on electrification in Nigeria and South Africa from a policy angle contributes to the existing knowledge base in the discipline.

Thesis (MBA (Business Management))--University of Stellenbosch, 2009.ENGLISH ABSTRACT: The purpose of this study is to determine whether residential electricity consumers within the Cape Peninsula would be willing to voluntarily purchase green electricity if it is sold at a premium price. International experience in the field of green marketing shows that while niche markets for green electricity clearly existed, few programmes however exceeded a 5% penetration in the residential market. This study therefore methodologically drew on recent development in the literature of norm-motivated behaviour to identify testable factors that could influence residential consumers’ willingness to purchase premium-priced green electricity. After identifying these core testable factors, they were used to test various hypotheses. This was done through the testing of primary data that was collected through a telephone market survey of 405 respondents within the Cape Peninsula. These respondents were all identified as financial decision makers within their electricity consuming households. This study subsequently found that residential electricity consumers in the Cape Peninsula are very concerned about the future of the environment and that a large percentage of them (more than 40%) from almost all income levels might voluntary buy premium-priced green electricity. However, as it did identify that consumers must truly be convinced of the positive effects that green electricity would have on the environment before voluntarily supporting such a campaign, it found that consumers might not be well enough informed on environmental and climate change issues to ensure their actual support. To be at all successful, such a green electricity marketing campaign should be very informative and specifically focused on the positive effects that such a purchase would have on the environment. This study also found that supportive residential consumers would on average be willing to pay a maximum premium of 26% or approximately 15c/kWh. The combined maximum potential value of these premiums amount to R39 million per month. This serves as indication that there is much room for future development of the green electricity market. This study also identified that the majority of residential consumers believe that excessive users of electricity should be forced to make a larger financial contribution towards the generation of green electricity than low usage consumers. Based on its findings, the study closes with recommendations to role players in the green electricity market, i.e. the City of Cape Town Municipality, Darling Wind Farm and Eskom.
AFRIKAANSE OPSOMMING: Die doel van hierdie studie is om te bepaal of residensiële elektrisiteitsverbruikers in die Kaapse Skiereiland gewillig sou wees om vrywilliglik groen elektrisiteit teen ’n premie aan te koop. Internasionale ervaring op die gebied van groen elektrisiteit het getoon dat, alhoewel daar verseker nismarkte vir groen elektrisiteit bestaan, baie min programme meer as 5% van die residensiële mark kon wen. Hierdie studie steun dus metodologies op onlangse verwikkelinge in die literatuur rakende normgemotiveerde gedrag om sodoende toetsbare faktore te identifiseer wat moontlik verbruikers se bereidwilligheid om groen elektrisiteit teen ’n premie te koop, kan verbeter. Na die identifisering van hierdie toetsbare faktore is hulle gebruik om verskeie hipoteses te toets. Dit is gedoen deur die toets van primêre data wat deur middel van telefoon-marknavorsing by 405 respondente binne die Kaapse Skiereiland ingesamel is. Hierdie respondente was almal geïdentifiseer as finansiële besluitnemers van huishoudings wat elektrisiteit gebruik. Hierdie studie het bevind dat residensiële elektrisiteitsverbruikers in die Kaapse Skiereiland baie besorg is oor die toekoms van die omgewing en dat ’n groot hoeveelheid van hierdie huishoudings (meer as 40%) van amper alle inkomstegroepe moontlik gewillig sou wees om groen elektrisiteit teen ’n premie aan te koop. Die studie het ook bevind dat omdat hierdie bereidwilligheid van die residensiële verbruikers onderhewig is aan hul oortuiging dat groen elektrisiteit ’n werklike positiewe effek op die omgewing uitoefen, residensiële verbruikers dalk huidiglik nie werklik goed genoeg ingelig is rakende omgewingsbewaring- en klimaatsveranderingskwessies nie. Hierdie gebrek aan kennis kan dus moontlik hul bereidwilligheid om groen elektrisiteit teen ’n premie aan te koop, negatief beïnvloed. Om suksesvol te wees sal groen elektrisiteit-bemarkingsveldtogte baie volledige inligting moet verskaf en sterk gefokus moet wees op die omgewingsvoordele wat die aankoop van groen elektrisiteit inhou. Die studie het ook bevind dat residensiële ondersteuners bereid sou wees om gemiddeld ’n maksimum premie van 26% of 15c/kWh te betaal. Die gesamentlike maksimum potensiële waarde van hierdie premies is R39 miljoen per maand wat daarop dui dat daar heelwat ruimte mag wees vir toekomstige uitbreiding van die mark vir groen elektrisiteit. Hierdie studie het ook geïdentifiseer dat die meerderheid residensiële elektrisiteitsverbruikers glo dat oormatige elektrisiteitsverbruikers gedwing moet word om ‘n groter finansiële bydrae tot die opwekking van groen elektrisiteit te maak as lae elektrisiteitsverbruikers. Gebaseer op die bevindinge van hierdie studie, sluit dit af met aanbevelings tot verskeie rolspelers in die mark vir groen elektrisiteit, soos die Kaapstadse Munisipaliteit, Darling Windplaas en Eskom.
