The paper surveys the literature and publicly available information on market power monitoring in electricity wholesale markets. After briefly reviewing definitions, strategies and methods of mitigating market power we examine the various methods of detecting market power that have been employed...

This paper shows that generators exercised increasing market power in the England and Wales wholesale electricity market in the second half of the 1990s despite declining market concentration. It examines whether this was consistent with static, non-cooperative oligopoly models, which are widely...

This paper provides an overview of the development of electric power transmission access, pricing and investment policies in the U.S. over the last 15 years and evaluates the current state of those policies. It includes a discussion of pre-liberalisation transmission access and pricing policies,...

During the Summer of 2000, wholesale electricity prices in California were nearly 500% higher than they were during the same months in 1998 or 1999. This price explosion was unexpected and has called into question whether electricity restructuring will bring the benefits of competition promised...

A structural shift from transaction-based, marginal cost pricing to fee-based service business models often accompanies We emergence of “platform” markets, i.e. multi-sided markets where an intermediary captures the value of the interaction between user groups. The many examples include...

Public electricity provision in Africa has been marred by under investment and frequent power outages.One of the strategies often adopted by firms to cope with this poor public supply is investment in backup generation. This strategy is not without cost however. Extant literatures on outage cost...

The framework proposed by Ofgem, OFT and CMA invokes a well-functioning market, but the Competition Commission has not always used such a concept, and when it has done so it has been problematic. Here, the well-functioning market is Ofgem's vision of a successful market, not anchored in any...

Efficiency and productivity analysis is a central concept in incentive-based regulation of network utilities. However, the efficiency measures obtained from benchmarking predominantly reflect short term performance and hence, provide only a snapshot of the firm's path towards its long run...

The incentive regulation of costs related to physical and cyber security in electricity networks is an important but relatively unexplored and ambiguous issue. These costs can be part of a cost efficiency benchmarking or alternatively dealt separately. This paper discusses the issues and...

This study explores and quantifies the benefits of connecting more distributed generation (with and without the use of smart connections) across different parties (Distribution Network Operators, wider society and generators). Different connection scenarios are proposed (with partial and full...
