| Abstract | Recently the soaring economic growth in Taiwan has increased
electric system's peak load. Since there was no increment in
generating capacity in the past two years, load management has
played an important role in coping with the decreasing reserve
margin. Time-of-Use (TOU) tariff structure was introduced ten
years ago for implementing the goal of load management because it
serves as the way of indirect control of loads. An econometric
model is used to examine the quantitative response to 3-section
TOU rates by five selected industries' customers. Load patterns
under the TOU tariff structure were compared with those that
would have occurred under an equivalent uniform rate structure.
The characterization of TOU customer's response is identified by
comparing the average demands among TOU periods and relative peak
loads under equivalent uniform and TOU rates. By using the
related prices and consumptions, social welfare changes when TOU
rates were applied, are also analyzed. Furthermore, the argument
of whether TOU pricing increases the utility’s profits has been
demonstrated for 3-section TOU customers.
We find that TOU customers were highly responsive to 3-section TOU prices, and the TOU period's electricity had apparent
substitutability in most of the selected industries. The
comparison for the TOU period's consumption under equivalent
uniform and TOU rates shows customers generally curtail e d the
electricity usage in peak period. Moreover, the estimated social
welfare changes suggest that 3-section TOU rate structure
actually provides welfare gains on formal welfare economic
viewpoint, and the analysis of the revenue s under three different
tariff structures ascertains that 3-section TOU pricing decreased
the utility’s revenue when compared with regular service pricing. |
