The requirement for significantly higher electricity network investment in the UK seems certain as the capacity of distributed generation and large scale renewables increases on the system. In this paper, which forms a chapter in the forthcoming Book “Delivering a Low Carbon Electricity System: Technologies, Economics and Policy” 2 , the authors make a number of significant suggestions for impr...

In this paper, we attempt at an analysis of the political economy of the Indian power sector with special reference to Kerala in the light of a generic model of the political economy of public utilities we develop in the first part of the paper. The model seeks to explain the political economy of the rent seeking drives in a non-Smithian imperfect regime of self-interest maximisation, with a re...

We investigate the impacts of electricity market restructuring on fuel effciency, utilization and, new to this area, cost of coal purchases among coal-fired power plants using a panel data set from 1991 to 2005. Our study focuses exclusively on coal-fired power plants and uses panel data covering several years after implementation of restructuring. The estimation compares how investor-owned (IO...

Relatively little is known about the practice of settlement rather than litigation in US utility regulation, or about the activities of consumer advocates. This paper presents evidence from Florida. During 1976-2002, over 30 per cent of earnings reviews were settled by stipulations involving the Office of Public Counsel but only 5 per cent of other cases. Over three quarters of the rate reducti...

In this paper we investigate the factors contributing to the fall in the Lerner Index (price-cost margin) in the British electricity market during the 90s. A first stage of our analysis models the number of breaks in the Lerner Index and their dating as unknowns. Our results suggest the existence of one structural break in the time series of the Lerner Index. The break point interval includes t...

In the course of the liberalization of the European energy markets, the German government opted – diverging from all other European countries – for Negotiated Third-Party Access. In this article we analyze if this institutional regime could theoretically lead to efficient market outcomes. Above that, we empirically review whether certain aspects of the actual implementation, the publication of ...

Implementation of 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 in the sector. This paper reviews the industrial organisation literature on innovation to explore the causes of the decline in energy R&D spending and shows that it ...

Most US consumers are charged a near-constant retail price for electricity, despite substantial hourly variation in the wholesale market price. This paper evaluates the …rst program to expose residential consumers to hourly real-time pricing (RTP). I …nd that enrolled households are statistically signi…cantly price elastic and that consumers responded by conserving energy during peak hours, but...

The integration of large amounts of distributed energy resources (DERs) as photovoltaic solar generation, micro-cogeneration, electric vehicles, distributed storage or demand response pose new challenges and opportunities on the power sector. In this paper, we review the current trends on: i) how consumers adopting DERs can self-provide energy services and provide other services at system level...
