Proposals have been made to deregulate the power generation function of electric utilities. But unregulated generators would be spatial oligopolists, because transmission costs would insulate them from competition from distant producers. The purpose of this analysis is to estimate the degree to which unregulated power generators would be able to exercise market power. This is accomplished by calculating spatial price equilibria for a hypothetical deregulated power market in New York State. Two types of equilibria are calculated: Nash/Bertrand equilibria, representing a lower bound to unregulated prices, and limit pricing, defining an upper bound. Equilibria are obtained for the years 1980 and 2000.

The model show that, on average, prices would increase under deregulation to level that are closer to marginal cost than regulated prices. Consequently, social welfare, defined as the sum of consumer and procedure surplus, increases, but profits increase even more. Nevertheless, costumer of high-cost utilities in the region would enjoy the lower prices under deregulation, which would threaten those utilities with bankruptcy.
