Benchmarking and regulation: international electricity experience

Abstract An increasing number of countries are adopting incentive regulation to promote efficiency improvement in electricity transmission and distribution utilities. Incentive regulation almost invariably involves some form of benchmarking or comparison of actual versus some reference performance. This paper discusses the main benchmarking methods and presents the findings of a survey of the methods used in the OECD and a few other countries. We find and discuss a variety of methods used by the regulators with a notable preference for the non-parametric methods. The paper also outlines the main outstanding issues and lessons for best practice implementation of benchmarking for regulation.

International benchmarking and regulation: an application to European electricity distribution utilities

Due to a shortage of data and increased international mergers, national energy regulators are looking to international benchmarking analyses for help in setting price controls within incentive regulation. We present an international benchmarking study of 63 regional electricity distribution utilities in six European countries that aims to illustrate the methodological and data issues encountered in the use of international benchmarking for utility regulation. The study examines the effect of the choice of benchmarking methods using DEA, COLS and SFA models. We discuss what problems of international benchmarking are highlighted by the study and how they can be overcome.

Electricity sector reform in developing countries : a survey of empirical evidence on determinants and performance

Driven by ideology, economic reasoning, and early success stories, vast amounts of financial resources and effort have been spent on reforming infrastructure industries in developing countries. It is therefore important to examine whether evidence supports the logic of reforms. The authors review the empirical evidence on electricity reform in developing countries. They find that country institutions and sector governance play an important role in the success and failure of reform. And reforms also appear to have increased operating efficiency and expanded access to urban customers. However, the reforms have to a lesser degree passed on efficiency gains to customers, tackled distributional effects, and improved rural access. Moreover, some of the literature is not methodologically robust and on par with general development economics literature. Further, findings on some issues are limited and inconclusive, while other important areas are yet to be addressed. Until we know more, implementation of reforms will be more based on ideology and economic theory rather than solid economic evidence.

Quality of Service, Efficiency and Scale in Network Industries: An analysis of European electricity distribution

Quality of service (QoS) is of major economic significance in natural monopoly infrastructure industries. In this article, we present an efficiency analysis of electricity distribution networks from seven European countries. We apply the stochastic frontier analysis method to multi-output translog input distance function models to estimate cost efficiency and scale economies. We show that introducing the quality dimension into the analysis affects estimated efficiency significantly, especially that smaller utilities’ efficiency seems to decrease. Our results emphasize that QoS should be an integrated part of efficiency and economic analysis of regulated natural monopolies.

BENCHMARKING AND REGULATION OF ELECTRICITY TRANSMISSION AND DISTRIBUTION UTILITIES: LESSONS FROM INTERNATIONAL EXPERIENCE

Since the early 1980’s, many countries have implemented electricity sector reform, many of which have bundled generation, transmission, distribution and supply activities, and have introduced competition in generation and supply. An increasing number of countries are also adopting incentive regulation to promote efficiency improvement in the natural monopoly activities - transmission and distribution. Incentive regulation almost invariably involves benchmarking or comparison of actual vs. some reference performance. This paper reviews the main approaches to incentive regulation and discusses various benchmarking methods. We also present the finding of a survey of the use of benchmarking methods in the OECD and few other countries. Our survey finds a variety of methods used by the electricity regulators although with a notable preference for the non-parametric methods. We then draw conclusions based on the finding of the survey highlighting the main outstanding issues and lessons for best practice implementation of benchmarking in electricity regulation.

Learning Curves For Energy Technology: A Critical Assessment

In this paper, which forms a chapter in the forthcoming Book “Delivering a Low Carbon Electricity System: Technologies, Economics and Policy” † , Jamasb and Kohler revisit the literature on learning curves and their application to energy technology and climate change policy analysis and modeling. The academic literature and policy documents have in recent years embraced the learning curves and applied the concept to technology analysis and forecasting cost reductions. We argue that learning curves have often been used or assumed uncritically in technology analysis and draw parallels between the use of learning rates in energy technological progress and climate change modeling to that of discount rates in social cost benefit analysis. The paper discusses that care needs to be taken in applying learning curves, originally developed as an empirical tool to assess the effect of learning by doing in manufacturing, to analysis innovation and technical change. Finally, we suggest some potential extensions of learning curves, e.g. by incorporating R&D and diffusion effects into learning models, and other areas where learning curves may potentially be a useful tool in energy technology policy and analysis.

Smart Metering and Electricity Demand: Technology, Economics and International Experience

In recent years smart metering of electricity demand has attracted attention around the world. A number of countries and regions have started deploying new metering systems; and many others have set targets for deployment or are undertaking trials. Across the board advances in technology and international experience characterize the metering landscape as a fast-changing one. These changes are taking place at a time when increasing emphasis is being placed on the role of the demand-side in improving the efficiency of energy markets, enhancing security of supply and in unlocking the benefits of energy and carbon savings. Innovative forms of metering can be a useful tool in achieving an active demand-side and moving beyond a supply-focused sector. In this paper we focus in particular on smart metering in liberalized electricity markets. We firstly set the context for innovative electricity metering in terms of policy, the role and market structure for metering, and the potential for smart metering to increase demand-side participation. We then provide an overview of new metering technologies by examining international trends, the various components of smart metering systems, and the likely future developments. Next we assess the economics of smart meters focusing on the costs and benefits of smart metering and the distribution of these. We review the evidence in Europe, North America and Australia; we look at how countries and regions have differed in their approaches and how these differences have had an impact on policy making. We conclude by outlining the main challenges that remain, particularly in technology choice and its regulation, the methodology of analyzing costs and benefits and the role of uncertainty in investment and policy making.

Reform and Regulation of the Electricity Sectors in Developing Countries

The 1990s witnessed a worldwide trend toward electricity sector reforms in developed and developing economies. These reforms have generally been based on private participation, regulatory reform, and competition in the sector. This paper reviews and draws lessons from the reform experience in developing countries. Developing countries have had to reform technically and financially less efficient electricity systems with less developed private sectors, weak economic and political institutions, shortage of skilled human resources, and lack of regulatory experience. The paper argues that competition and regulatory reform are equally important to the success of reforms. Also, the sector’s systemic characteristics and the country’s institutional endowment should weight equally in the design of reforms. In addition, distributional and access to service aspects of reforms call for a redefined state involvement rather than a complete withdrawal from the sector.

Core Indicators for Determinants and Performance of the Electricity Sector in Developing Countries

Since the early 1990s, substantial resources and efforts have been spent on implementing market-oriented electricity reforms in developing countries. While there are important sectoral, economic, and social dimensions involved in electricity reform, empirical analysis and evaluation of reforms have been of limited use for testing the economic rationale of reforms and policy advice. This may partly be attributed to a lack of generally accepted and measured indicators for monitoring the progress, impacts, and performance of reforms. In this paper the authors propose a set of indicators as a first step toward filling this gap and developing a coherent framework for studying electricity reform in developing countries that covers resource and institutional endowments, key reform steps, market structure, performance, and various impacts.

Technical Change Theory and Learning Curves: Patterns of Progress in Energy Technologies

This paper presents a comparative analysis of energy technology learning and progress within the framework of Schumpeter’s invention-innovation-diffusion paradigm. We estimate learning by doing and research rates for a range of energy technologies in four stages of technical progress. Emerging and mature technologies respond slowly to research and development (RD evolving technologies exhibit high learning-by-doing and research rates; reviving technologies exhibit considerable response to learning-by-research although they do not face significant market constraints. We generally find higher learning-by-doing than learning-by-research rates but do not find any development stage where learning-by-doing alone is the dominant driver of technical change. Also, high capital intensity and market constraints appear to slow down the pace of progress of emerging and evolving technologies. We find little scope for potential substitution between learning-by-doing and learning-by-research across the technologies and different stages of their development path.
