Résumé :

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

Résumé :

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

Résumé :

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.

Résumé :

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

Résumé :

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

Texte intégral

Résumé :

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

Résumé :

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.

Résumé :

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.

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.

Résumé :

We provide evidence that the problem of raising capital in the early days of the U.S. electric-utility industry motivated industry leaders to embrace state rate-of-return regulation in return for a secure territorial monopoly. Utility executives anticipated that this would lead to a reduction in borrowing costs. Using firm-level bond data for 1910–1919, we estimate a model and find that state regulation led to lower borrowing costs but that the magnitude of the reduction was small. We also find evidence that output of electric utilities in states with regulation was higher than output in state

I construct a much simpler two-contract menu that can achieve more than 65% of these welfare gains.

Résumé :

Since its foundation in 1906, the Hydro-Electric Power Commission of Ontario exerted a major influence on the politics of electricity in the United States. American supporters of publicly-owned utilities saw the Hydro as a model worth emulating south of the border. Reformers who sought lower electric prices for consumers also looked to the Hydro for evidence of the technically-feasible lowest cost of producing and transmitting this source of energy. This paper will examine a specific instance when American Progressives sought to use the Hydro as both a source of information and inspiration for

Two vaccines against rotavirus diseases, Rotarix® and RotaTeq®, are being marketed in Spain; but rotavirus is not presently among the diseases covered by universal vaccination in Spain. The aim of this study was to assess the efficiency of extending Spain’s current targeted rotavirus vaccination strategy including only preterm babies, to a policy of universal vaccination. A de novo cohort-based Markov model was built to evaluate the efficiency of three compared rotavirus vaccination strategies in Spain: targeted, universal, and no vaccination. Using Rotarix® or RotaTeq®, we compared the cost–u

Résumé :

Electric Road Systems (ERS) are emerging technologies that enable electricity transfer to electric vehicles in motion. However, their implementation presents challenges due to high energy demands and infrastructure requirements. This technology offers a significant opportunity for decarbonizing road freight transport, one of the most carbon-intensive sectors, contributing to the European Union’s climate goals. This study hypothesizes that implementing an inductive ERS for freight transport along the AP-7 corridor in Spain will generate environmental benefits—primarily through greenhouse gas (G

Findings from monitoring and computer simulation studies indicate that trees can be a cost-effective energy conservation measure for some electric utilities. Our simulations suggest that a single 25-ft tall tree can reduce annual heating and cooling costs of a typical residence by 8 to 12 percent ($10-25). Assuming annual savings of $10 per household, a nationwide residential tree planting program could eventually save about $1 billion each year. A study of the potential for energy-conserving shade tree plantings within residential sections of San Diego found that over 40 percent of all houses

Abstract Renewable energy sources have evolved into a technologically and economically feasible choice for use by electrical utilities. Furthermore, the widespread usage of renewable energy sources is driving policymakers and utilities to increase green energy’s role to ensure long-term economic growth. The most influential non-conventional energy source for generating power is solar energy. Electric power systems must be designed, built, and run in such a way that the majority of energy demand for loads is supplied reliably, cost-effectively, and in an environmentally responsible manner.

Community microgrids are applicable universally because they can decentralise grid-connected areas and electrify remote areas. Moreover, they can provide energy security by improving the reliability and resiliency of electric distribution while diminishing the infrastructure costs of preserving or constructing electric power generation, transmission, and distribution assets. Using renewable energy sources (RESs) maybe incentivised through the government and utilities, which can help make such projects economically viable.

Climate change motivated by human activities constitutes one of the main challenges of this century. To cut carbon emissions in order to mitigate carbon’s dangerous effects, the current energy generation mix should be shifted to renewable sources. The main drawback of these technologies is their intermittency, which will require energy storage systems to be fully integrated into the generation mix, allowing them to be more controllable. In recent years, great progress to develop an effective and economically feasible energy storage systems, particularly motivated by the recent rise of demand f

The assessment of wastewater treatment plant (WWTP) performance has gained the interest of water utilities and water regulators. Eco-efficiency has been identified as a powerful indicator, as it integrates economic and environmental variables into a single index. Most previous studies have employed traditional data envelopment analysis (DEA) for the evaluation of WWTP eco-efficiency. However, DEA allows the selection of input and output weights for individual WWTPs for the calculation of eco-efficiency scores.
