Abstract:

Historically, utilities have been granted a natural monopoly status through the regulatory process. Under such conditions, utilities need to prove to their regulators that their expenditures were necessary to comply with imposed “obligation to serve.” When these prudency arguments are successful, the utilities may recover their costs plus a rate of return.Some have argued that this structure has not created an environment that fosters productive efficiency. With deregulation on the horizon, the utility business is changing. To survive the 21st century, utilities need to find ways to improve th

Abstract:

It is likely that deregulation of the electric utility industry will force high-cost electric utilities to write off the “stranded” cost of plant and equipment that would be rendered obsolete in a competitive marketplace. In this paper, we examine the financial statement analysis implications of ongoing deregulation. Based on 1993 data for a sample of 111 large investor-owned electric utilities, our analyses suggest that it is possible to use financial statement data to form estimates of these potentially stranded costs. In addition, we find that recent trends toward deregulation are associate

Abstract:

In Spain, the water supply service is a municipal responsibility and in general is a sector without competitors. For this reason, an efficiency analysis attains greater significance. This study uses Data Envelopment Analysis (DEA) to estimate the efficiency of different urban water utilities. An extensive data search, where several variables such as the capital expenditure, the cost of material, or the labor have been recorded, has allowed evaluating the relative efficiency of the most important Spanish water distribution networks in using their resources. Furthermore, their sustainable effici

Abstract:

The authors use survey and interview data from California homeowners to understand customers’ trust in their utility company. The authors find that customers’ beliefs about the reliability of electricity do not predict trust. Instead, what matters are beliefs that the utility company does a bad job managing customer service, costs, and wildfires. Distrust among survey respondents aligns with interview participants’ descriptions of utility companies as powerful, greedy monopolies that benefit themselves at the expense of helpless consumers. These results have implications for the energy transit

Abstract:

In theory, regulators concerned about inequality will deviate from efficient two-part tariffs, charging lower-than-efficient fixed monthly fees and higher-than-efficient per-kilowatt-hour prices. To quantify that relationship, we develop a measure of the redistributive extent of utility tariffs: the “electric Gini.” Utilities with higher electric Ginis shift more costs from households using relatively little electricity to households using more. In practice, US utilities whose ratepayers have more unequal incomes have higher electric Ginis. But electricity demand is only loosely correlated wit

Abstract:

If electric power is distributed by an overhead network of cables, the ignition of wildland fires is unavoidable, although prudent management efforts can reduce the losses. The economic aspects of these fires are driven by tort litigation, which tends to create serious problems of social fairness. The present system does not contain adequate incentives towards minimizing these costs, nor appropriate measures to ensure that costs are allocated in a fair manner. The problems are universal, but a specific focus on the wildfire situation in California is assumed. The electric utilities there are r

Abstract:

Stranded costs in the electric utility industry—the past costs incurred by incumbent utilities that could not be recovered in a competitive market environment—have been a troubling and troublesome policy issue for electricity deregulation. Although electricity deregulation surely would have proceeded slowly in any event,1 the stranded cost question— who (customers? shareholder-owners?) will absorb the losses in the forthcoming competitive environment?—has clearly slowed the process even further.

Abstract:

Market responsive pricing is a fundamental requirement if natural gas is to play its full part in meeting Canada's energy needs. Regulation must be modified to enable flexibility in buying, transporting and selling natural gas in a market responsive manner. Taxes should be based on profits, not on revenues and, because utility costs, by definition, flow through to the customers, taxation of natural gas utilities should be equitable in relation to electric power utilities.

Abstract:

Social costing refers to the regulatory practice of requiring electric utilities to incorporate external costs into utility decision making. This practice is being adopted by a growing number of state public utility commissions (PUCs). The effectiveness of this new regulatory approach in reducing the social costs of supplying electricity will depend on the range of utility decisions covered. We use a utility planning model and illustrative estimtes of environmental costs to analyze the implications of different social costing regimes for generation technology choice, social and private costs o

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 su

Modeling electricity spot prices is essential for asset and project valuation as well as risk management. I introduce the mean-reversion feature into a classical variance gamma model to model the electricity price dynamics as a mean-reverting variance gamma (MRVG) process. Derivative pricing formulae are derived through transform analysis and model parameters are estimated by the generalized method of moments and the Markov Chain Monte Carlo method. A real option

Since the early 1960’s, the use of aero-derivative and industrial gas turbines on TransCanada’s natural gas transmission system has been the norm, with a total of 245 units installed to date. In 1996 and 1997 the company installed six high-speed, 30.6 MW, variable speed, electric drive systems. In the same time period eight aero-derivative gas turbines of similar power, with Dry Low Emissions, were installed. After an elapse of three years running time we now have enough data to compare the performance of the two different compressor drivers. A comparison of the performance of the two prime mo

Abstract:

This paper presents an assessment of the failure modes, operation and maintenance (O&M) costs, and system lifecycle costs for 77 photovoltaic (PV) water pumping systems installed during a fourteen year period from 1990 to 2004. These systems were supplied, installed, operated and maintained through a customer lease program by two rural utilities, Northwest Rural Public Power District in Nebraska and Verendrye Electric Cooperative in North Dakota. Field records have been tracked and analyzed to capture maintenance events, component failure experience, repair/replacement costs and installati

Abstract:

A 35 kW roof top photovoltaic (PV) system has been installed at the National Institute of Standards and Technology (NIST) in Gaithersburg, Maryland. The system, located on the flat roof that connects NIST’s Administration Building to its adjoining conference and cafeteria facilities, produced NIST’s first site-generated renewable energy on September 14, 2001. In addition to providing electrical energy and reducing monthly peak electrical loads, the rear surface of each module is laminated to 51 mm of extruded polystyrene enhancing the thermal performance of the roof.

Abstract:

A comparison between power plants built according to the HAT (Humid Air Turbine) and SCGT/CC (Semi-Closed Gas Turbine/Combined Cycle) concepts is presented, ranging from thermodynamic performance (efficiency and specific power output) to projected data for plant construction and operating costs. Both options appear to be of potential interest to electric utilities considering advanced gas turbine power plants, with significant differences form the point of view of plant size, water consumption, and adaptability to advanced developments for the limitation of environmental impact (CO2 emissions)

Abstract:

The increase in electricity prices, which peaked in August 2022, has affected the various activities carried out in the Spanish electricity sector differently. This paper analyses the impact of this increase on the sector, distinguishing between electric power companies and electricity retailers, paying special attention to their operating profit and, particularly, to the influence of aspects such as (i) the incidence of forward contracts with a fixed price, (ii) asymmetric exposure to price increases in wholesale electricity markets, or (iii) belonging to vertically integrated groups, in the

Abstract:

The economics of high voltage direct current for long-distance transmission of electrical energy have been reported as very attractive, to the extent that several projects are in the making. Several reasons other than the savings in transmission costs, for example the exchange of peak power between time zones and seasonal zones, would permit utilities to save on plant investment for generating capacity while maintaining a high level of service. This report summarizes work on the initial phase of a study to determine the effects of high-voltage direct-current (H.V.D.C.) electric transmission li

Abstract:

The Brazilian continental dimensions and diversified natural resources are proportional to the challenges to develop its infrastructure sustainably and supply proper public services to more than 200 million inhabitants. Energy consumption has doubled since 1990, fostered by economic growth and the expansion of middle class. In this context, promote energy efficiency, in a broad sense, is urgent and rational. Brazil has a relatively long history in promoting energy efficiency at final user level. A landmark of this process is the Brazilian Labeling Program, launched in 1984, as direct consequen

Abstract:

1.1 Macroeconomic summary Economic recovery has consistently outperformed the technical staff’s expectations following a steep decline in activity in the second quarter of 2020. At the same time, total and core inflation rates have fallen and remain at low levels, suggesting that a significant element of the reactivation of Colombia’s economy has been related to recovery in potential GDP. This would support the technical staff’s diagnosis of weak aggregate demand and ample excess capacity. The most recently available data on 2020 growth suggests a contraction in economic activity of 6.8%, lowe
