Abstract:
This paper investigates the long-run effects of average revenue regulation on an electricity transmission monopolist who applies a two- part tariff comprising a variable congestion price and a non-negative fixed access fee. A binding constraint on the monopolistfs expected average revenue lowers the access fee, promotes transmission investment, and improves consumer surplus. In a case of any linear or log-linear electricity demand function with a positive probability that no congestion occurs, average revenue regulation is allocatively more efficient than a Coasian two-part tariff if a positive access fee under average revenue regulation is lower than that under a Coasian two-part tariff.
