This paper studies the market power of generators in the electricity market when transmission capacity is scarce. We consider a simple world of two generators providing electricity to their consumers through a single transmission line. In the literature, different Cournot equilibrium concepts...

This paper introduces strategic behavior of the electricity network operator in a congested network with imperfect competition for generation. It models a two stage Stackelberg game. First, the network operator sets transmission prices, then generators set output and sales. Several scenarios for...

This paper looks at the potential effect of partial ownership on the generation and the transmission sector of electricity markets. Ideally, in liberalized electricity markets, transmission is separated form generation. The transmission sector is a natural monopoly operated by a regulated...

Abstract: This paper derives the socially optimal transmission prices in a congested electricity network when there is imperfect competition in generation, and when the budget constraint of the network operator is binding. The results which we derive are a generalization of the standard Ramsey...

A small region has a high cost monopolistic electricity generator. It is connected through a low capacity transmission line with a large, competitive low cost region. Access to the transmission line is auctioned. I show that, if consumers arbitrate on the regional price differences, the...

We demonstrate how an incumbent producer of commodities can use cash-settled derivatives contracts to deter entry and extract rents from a potential competitor. By selling more derivatives than total demand, the producer commits to low prices and forces the entrant to price low upon entry. By...

This paper studies the welfare implications of using market mechanisms to allocate transmission capacity in recently liberalized electricity markets. It questions whether access to this essential facility should be traded on a market, or whether the incumbent should retain exclusive usage...

This paper reports the results of an experiment evaluating three regulatory schemes for network infrastructure, in terms of their ability to generate efficient levels of capacity investment. We compare the performance of (1) price cap regulation, (2) a regulatory holiday for new capacity, and...
