Evaluating the Evidence on Electricity Reform: Lessons for the South East Europe (SEE) Market
This paper discusses the evidence on electricity reform and relates it to the current situation of the South East Europe (SEE) electricity market. We begin by discussing the main elements of the European Union (EU) electricity reform model. Then we go on to discuss emerging good practice in the regulation of national electricity markets in the EU. This is important because it reflects the key role placed on independent regulation of the electricity sector in the EU reform model. Next, we evaluate the empirical evidence on the success of the EU reform model in particular before and the success of electricity reforms more generally. This leads on to a discussion of the particular context of SEE electricity reform and what specific issues this raises. We conclude with a discussion of the importance of more general institutional context of SEE electricity reform. The paper suggests that it will be a substantial, but worthwhile, challenge to create a workable supra-national electricity market in the region

Deregulation and R&D in Network Industries: The Case of the Electricity Industry
Electricity reform has coincided with a significant decline in energy R&D activities. Technical progress is crucial for tackling many energy and environmental issues as well as for long-term efficiency improvement. This paper reviews the industrial organisation literature on innovation to explore the causes of this decline, and shows that it was predicted by the pre-reform literature. More recent evidence endorses this conclusion. At the same time, R&D productivity and innovative output appear to have improved in both electric utilities and equipment suppliers, in line with general improvements in the operating efficiency of the sector. Despite this, a lasting decline in basic R&D and innovation input into basic research may negatively affect development of radical technological innovation in the long run. There is a need for reorientation of energy technology policies and spending toward more basic research, engaging more firms in R&D, encouraging collaborative research, and exploring public private partnerships

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

Do Mergers Improve Efficiency? Evidence from Restructuring the U.S. Electric Power Sector
This paper analyses the performance impact of the merger wave which took place in the US
electricity industry during the period 1994-2003. It does so by analyzing the impact on operating and total cost in electricity distribution. While there are past studies of efficiency and productivity effects, as well as of prices, profits, and other outcomes, this study differs in several ways. First, the database consists of many merging and non-merging firms, rather than only a
few on which to base inferences. Second, all of these mergers arise in a single industry, greatly facilitating controlled comparison. Third, we have data on the several years of pre-merger and post-merger efficiency of the specific merging units, unlike virtually all past studies. And finally, we employ a powerful nonparametric technique - data envelopment analysis - to measure the
efficiency of each operating unit. The results indicate that electricity mergers are not consistent with improved cost performance
