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...

We demonstrate how suppliers can take strategic speculative positions in derivatives markets to soften competition in the spot market. In our game, suppliers first choose a portfolio of call options and then compete with supply functions. In equilibrium firms sell forward contracts and buy call...

Coordinating the timing and location of new production facilities is one of the challenges of liberalized power sectors. It is complicated by the presence of transmission bottlenecks, oligopolistic competition, and the unknown prospects of low-carbon technologies. The authors build a model...

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...

The liberalization of the electricity sector increases the need for realistic and robust models of the oligopolistic interaction of electricity firms. This paper compares the two most popular models: Cournot and the Supply Function Equilibrium (SFE), and tests which model describes the observed...

Abstract: We demonstrate how suppliers can take strategic speculative positions in derivatives markets to soften competition in the spot market. In our game, suppliers first choose a portfolio of call options and then compete with supply functions. In equilibrium firms sell forward contracts and...

In the most liberalized electricity markets, abuse of market power is a concern related to oligopolistic market structures, flaws in market architecture, and the specific characteristics of electricity generation and demand. Several methods have been suggested to improve the competitiveness of...
