Abstract:We measure the effect of incentive payments of residential time-of-day (TOD) electricity demand in summer, using data from a residential TOD electricity pricing experiment in the Kyushu region of southern Japan. During the experiment, participating households could receive incentive payments if they reduce their peak usage share. Results based on an econometric model indicate that households have shifted their electricity usage from peak to off-peak periods in response to the incentive payment, but the effect of the incentive payment on load shifting was modest.

Abstract:The Public Utility Regulatory Policy Act of
1978 (PURPA) required all electric utilities
to implement time-of-day (TOD) pricing or else
to "show cause" why TOD rates should not be
implemented in their service areas. In order to
comply with PURPA, electric utilities and public
utility commissions have been searching for evidence
pertaining to the costs and benefits of TOD
pricing in the residential sector. Some of the
most relevant evidence on this subject has been
generated in the TOD Demonstration Projects
sponsored by the former Federal Energy Administration
(FEA). I
The primary purpose of the present paper is to
clarify the record with regard to the incentive
payment that was implicit in the Arizona experiment
during its first year. Previous studies of the
Arizona data (Aigner and Hausman, 1980; Atkinson,
1977; Miedema et al., 1978; and Taylor,
1977) have either ignored this implicit payment
or else not properly taken it into account. This
has resulted in serious misrepresentations in both
the magnitude and direction of the Arizona TOD
responses. In the sections that follow, we shall
describe in detail the implicit incentive scheme,
indicate a way to take it into account, and provide
some estimates of time-of-day price elasticities
that are free of its confounding effects.
While the focus is on the Arizona experiment,
the problems analyzed are general and can arise
in any field experiment in which incentive
schemes play a role.
Abstract: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.
