On oligopolistic electricity market equilibria and contingent claims

Abstract

This paper deals with oligopolistic electricity market equilibria when strategic agents can trade in contingent claims, and more specifically options, markets. From the theoretical point of view, new results regarding existence and computation of these equilibria are presented. From the policy point of view, relevant questions regarding regulatory issues are arisen. In the particular case of the Spanish electricity market, the relevant ”options” can include fuel subsidies and certain aspects regarding Costs To Transition payments.
