Rate Innovation Trends
The Electric Power Research Institute's Survey of Innovative Rates: 1994 Update reviews innovative rates developed by 135 utilities in the continental United States. Figure 1 shows recent industry trends in providing some of the innovative rates judged more important in a competitive market. Between 1988 and 1992, the number of real-time pricing (RTP) rates available from the surveyed utilities more than doubled, from seven in 1988 to 15 in 1992. Over the same timeframe, the number of interruptible rates rose 65 percent, and the number of surplus rates increased 106 percent. Between 1990 and 1992, the number of customers opting for these rates increased by 82 percent, 32 percent, and 4 percent, respectively.
