Household response to optional peak-load pricing of electricity

I investigate the impacts of voluntary time-of-day (TOD) rates on residential demand for electricity My analysis is based on a sample of a survey, which provides cross-sectional data on electricity consumption and economic/demographic features for both TOD and non-TOD households in Japan. This information is used to develop an almost ideal demand system for the TOD electricity consumption during the summer. The results show that (1) household response to the high price of the peak period is relatively modest, and (2) the relative magnitudes of the price and selection effects depend on the ownership of water heaters.
