The Effects of Rivalry with Price Regulation of Electric Power Generation.

Authors

Abstract

This article examines how rivalry between an electric utility and nonutility generators (NUGs) affects electricity prices, market structure and welfare. If a utility cannot break even financially when outputs are priced at marginal cost, then the Ramsey optimal price paid by a utility purchasing electricity from a NUG should be below avoided cost, in contrast to the requirements of PURPA. The analysis also compares FDC, Residual and Ramsey prices for a utility's electricity sales. It illustrates how FDC prices may force a utility to exit relatively competitive business markets, eliminating any benefits of economies of scope from serving both business and residential customers.
