The purpose of this paper is to investigate the status quo of Global Reporting Initiative (GRI)-based sustainable public value (SPV) reporting by electric utilities. Furthermore, the study attempts to find out whether a stock exchange listing and/or a public ownership are positively associated with electric utilities’ reporting regarding their contributions to a sustainable development (SD) or not.

An empirical analysis of sustainability reports published by electric utilities from 28 different countries all over the world is carried out. The investigation is based on a documentary analysis of 83 GRI G4 reports.

The findings show that electric utilities’ coverage of GRI indicators of the electric utilities sector disclosures varies between, as well as within, the different categories of the GRI guidelines and that the coverage of sector-specific indicators is often lacking behind the general coverage rates. Furthermore, the study reveals that a stock exchange listing is positively associated with electric utilities’ GRI-based SPV reporting. In contrast, public ownership does not show a significant association.

Electric utilities have a significant influence on SD. They operate in a regulated environment that is targeted at utilizing electric utilities for economic and environmental public policy objectives. Against that background, the study discusses which issues of SPV creation are reported by electric utilities that use the GRI guidelines and therefore brings together the public value (PV) and the sustainability community.

Carbon dioxide emissions are considered to be one of the main culprits in global warming and the Kyoto Protocol specifically targets reductions in carbon dioxide to reduce global warming. Because the fossil burning electric utility plants are the primary industrial source of carbon dioxide emissions, we examine how effective the U.S. electric utility companies have been in reducing carbon dioxide emissions. We evaluate 1998 carbon dioxide emissions in relation to the emissions of the base year of 1990 set by the Kyoto Protocol. We also examine whether adequate disclosures are being made by the utilities to reflect their pollution performance. The findings show that the total amount of carbon dioxide emissions increased by 35% in 1998 compared to 1990, but on a relative basis, they decreased from 205 to 204lbs/MMBTU. Though we detect some support for a positive association between pollution disclosures and pollution emissions, the electric utilities in general do not disclose much about global warming or carbon dioxide.

Electric Utility Diversification and Efficient Capital Markets Over 60% of investor owned electric utilities have experimented with diversification into lines of business other than the traditional generation, transmission, and distribution of electricity. They diversify for a variety of reasons, but a primary goal is to improve their overall financial performance. Existing studies have found that diversified utilities outperform non‐diversified utilities. Measures of performance have included EPS growth, price‐earnings multiples, market‐book ratios and internal rates of return. However, many of these studies do not compare performance on a risk‐adjusted basis nor indicate whether differences are statistically significant. In contrast, this study compares performance using the efficient market hypothesis. Regression results indicate that there is no significant difference in risk between portfolios comprised of diversified utilities and non‐diversified utilities. Furthermore, no significant difference in return was observed. The performance of the two portfolios does not appear to differ in risk or return. These results tend to support the efficient market hypothesis concerning stockholders' inability to gain an advantage from publicly available information. Differences in company performance that are anticipated and already reflected in stock price do not result in differences in returns to stockholders.

The comparative potential impact of electric restructuring laws and attendant regulations on electric utilities and ultimately on their collective human resources in Ireland, Germany and in the Tennessee Valley, USA, is the focus of this research. It includes personal observations of utilities in both EU countries and in the Tennessee Valley as well as personal interviews with utility officials by Dennis Yocom, who has been associated with the electric utility industry for 27 years.

Very little is known about the influences of corporate strategy and regulation on the risk of regulated firms. The current study addresses this gap by examining the relationship among the level of diversification, the regulatory environment, and risk levels of regulated electric utility companies. Results suggest that both the regulatory environment and level of diversification impact firm risk. Specifically, the regulatory environment in which a firm operates moderates the relationship between diversification and risk. Electric utilities operating in the least favorable regulatory environments benefited the most from diversification in terms of risk reduction, while electric utilities in the most favorable regulatory environments experienced increases in risk from diversification. These findings extend previous studies by showing how both the regulatory environment and corporate strategy impact the risk of regulated utilities.

This paper aims to examine empirically if the encouragement by government policy of merger and acquisition activity involving municipal and provincially owned electricity distribution utilities (LDCs) in the Province of Ontario has had positive effects in terms of value creation, operating performance and economies of scale.

It was anticipated that with LDC consolidation, there will be increased operational efficiency and improvement in the cost-effectiveness of the merged electrical utility. Using matched pairs dependent t-testing and Wilcoxon signed-rank testing, the authors compared data for three years before and after the merger or acquisition of 16 municipal utilities (616 total observations) to determine if there were any statistically significant changes (positive or negative) in measures of financial, operational and service efficiency.

The findings indicate statistically significant increases in debt as a percentage of shareholder equity in post-merger/acquisition utilities and consequently leveraged higher returns on equity. However, there were no statistically significant changes in financial, operational or service efficiency measures (with the exception of decreased efficiency in telephone response).

A total of 16 mergers or acquisitions were reviewed involving 32 of 79 LDCs, with the research implications pointing to a need for existing policy to be reviewed to determine whether a more detailed examination is required by the provincial energy regulator, including a closer examination of managerial motives, before approving mergers between municipal electricity distributors. This research involves only a quantitative approach and further research would examine these transactions using qualitative measures for a deeper examination as to managerial motives.

The results suggest that the mergers or acquisitions to date have served only to increase shareholder risk without improvement in other financial, operational or service efficiencies, a contradiction to the rationale behind the Province’s merger policy.

The consolidation policy for Ontario LDCs has not resulted in any statistically significant improvement in electricity rates or service for consumers.

This paper is the first examination of the effects of Ontario’s LDC consolidation policy in terms of specific financial, operational and service efficiency measures.

While market theorists have devoted a great deal of effort to the conceptualization of service quality, the practical guidance available to service providers continues to be very limited. Utilizing the emerging role of a new marketing entity, the retail electric service provider, as an illustration, the article discusses how data envelopment analysis might be used to analyze service quality at the retail service level. Specific dimensions thought to influence consumers’ perceptions of the quality of retail electric energy services are identified, and the potential use of data envelopment analysis as a diagnostic tool for effective management of service quality by retail electric service providers is demonstrated. Generalization to different types of service providers is suggested. Empirical studies to develop practical guidance along this line of analysis are encouraged.

One of the most pressing questions facing small‐island development states (SIDS) is the appropriate way in which to operate and manage their infrastructure industries. After all SIDS are faced with high cost of infrastructure due to the narrow markets and diseconomies of scale and remoteness.

For small‐island utilities in the Caribbean region, a benchmark has been performed to demonstrate objectively how utilities cost, as well as their service quality, compare over time and with other utilities. About 15 utilities of 17 Caribbean countries were included in the benchmark. Based on these outcomes, the current efficiency and possible efficiency gains were determined (which may differ significantly from the current “best‐practice” of utilities in developed countries) which provide a basis to set targets that are achievable.

In this paper, the conducted Caribbean benchmark studies will be further elaborated and the applicability as management tool and regulatory tool to compare performance within the region will be assessed. One of the preliminary conclusions of the study is that the incentive‐based approaches adopted in many countries do not necessarily work within the context of SIDS (and their specific characteristics and limitations), so that a different regulatory model needs to be developed.

The analysis was performed based on data of one year. Analysis based on multi‐year data can provide trends in efficiency and will identify the development of the utilities' performance. Cost data was not used in this analysis due to lack of availability. Also, inclusion of reliability data representing frequency of interruptions and duration of interruption in the analysis would provide a more holistic indication of efficiency.

The paper offers insight into the current restructuring of the electricity supply in the Caribbean region.

Project portfolio management (PPM) has been recognized as critical for the productivity of research and development (R&D) investments, but empirical research on PPM use and outcomes in non-commercial R&D environments is limited. The purpose of this paper is to investigate PPM processes and outcomes in a unique R&D context within Brazilian electric power utilities.

An exploratory best practice survey was used to collect data on PPM processes, methods and performance results in the power sector. Analysis of the data employs descriptive statistics and comparative analysis in the light of the literature.

The findings emphasize the importance of strategic value and the need for PPM to be customized for the specific context. The results also demonstrate the importance of adopting selection criteria and measures in accordance with the organizations strategic goals.

The findings may help organizations better understand how PPM can be tailored for the environment. PPM managers in utilities and other non-commercial R&D environments may find guidance in tailoring and improving their PPM approaches.

The contributions of this paper are twofold. First, it provides empirical findings to support PPM concepts on strategic alignment and the importance of context by demonstrating how PPM works to deliver strategy in a unique environment. Second, it contributes to the management of R&D projects and portfolios in power utilities, providing an example and analysis that may offer guidance. The contributions from this study may also offer insights that are valuable for R&D management in other utilities, or for R&D management in general.
