Wright tariffs in the spanish electricity industry: The case of residential consumption.

Abstract

This paper develops a capacity price model for the Spanish electricity industry and presents utilization level tariffs as an example of duration tariffs (Wright tariffs) when duration is aproximated by the ratio of consumption to power used. With this model and with the data on residential consumption of electricity several optimal t\\'o part tariffs for the residential level of utilization considering several hypothesis on the configuration of the generating equipment are computed. This allows for the estimation of the degree of optimality of the current tariff and to obtain an aproximation of efficiency losses caused by the existing regulatory regime.Capacity princing; Wright tariffs; Residential electricity;
