A comparison of electricity market designs in networks

EP 31  | Non-Technical Summary | PDF

Abstract: In the real world two classes of market designs are implemented to trade electricity in transmission constrained networks. Analytical results show that in two node networks integrated
market designs reduce the ability of electricity generators to exercise market power relative to separated market designs. In multi node networks countervailing effects make an analytic analysis difficult. We present a formulation of both market designs as an equilibrium problem with equilibrium constraints. We find that in a realistic network, prices are lower with the integrated market design.

Gert Brunekreeft Market-Based Investment in Electricity Transmission Networks: Controllable Flow EP 29  | Non-Technical Summary | PDF Abstract: This paper discusses unregulated market-based electricity transmission investment by third parties as opposed to regulated investment by designated transmission system operators. The analysis is set against a European and Australian institutional background and focuses on interconnection of… Read more

Paul Joskow The Difficult Transition to Competitive Electricity Markets in the US EP 28 | Non-Technical Summary | PDF Abstract: This paper discusses the causes and consequences of state and federal initiatives to introduce wholesale and retail competition into the U.S. electricity sector from 1995. The development and performance of wholesale market institutions, the expansion… Read more

M Soledad Arellano Diagnosing and Mitigating Market Power in Chile’s Electricity Industry EP 27  | Non-Technical Summary | PDF Abstract: This paper examines generators’ incentives to exercise market power and the strategies they would follow if all electricity supplies were traded in an hourly-unregulated spot market. The industry is modelled as a Cournot duopoly with… Read more

Joanne Evans, Richard Green Why Did British Electricity Prices Fall after 1998? EP 26  | Non-Technical Summary | PDF Abstract: In an attempt to reduce high electricity prices in England and Wales the government has reduced concentration among generators and introduced New Electricity Trading Arrangements (NETA). Econometric analysis on monthly data from April 1996 to… Read more

Paul Joskow, Jean Tirole Merchant Transmission Investment EP 24  | Non-Technical Summary | PDF Abstract: We examine the performance attributes of a merchant transmission investment framework that relies on ‘market driven’ transmission investment to provide the infrastructure to support competitive wholesale markets for electricity. Under a stringent set of  assumptions, the merchant investment model appears… Read more

Jean-Michel Glachant, Virginie Pignon Nordic Electricity Congestion’s Arrangement as a Model for Europe: Physical Contraints or Operators’ Opportunity EP 20 | Non-Technical Summary | PDF Abstract: Congestion on power grids seems a physical reality, a “hard” fact easy to check. Our paper models a different idea: congestion signal may be distorted by transmission system operators… Read more

Tooraj Jamasb, Paul Nillesen, Michael Pollitt Strategic Behaviour under Regulation Benchmarking EP 19  | Non-Technical Summary | PDF Abstract: Liberalisation of generation and supply activities in the electricity sectors is often followed by regulatory reform of distribution networks. In order to improve the efficiency of distribution utilities, some regulators have adopted incentive regulation schemes that… Read more
