<br />above that projected for 1981, and 0.3 percent less than the 185,454 GWH <br />produced in 1980. <br /> <br />Table 2 tabulates on a regional and area basis the projected <br />firm peak load average annual compound growth rates based on the previous <br />year's actual peak load and the ten-year forecast as of January 1, 1972 <br />through 1982. The projected growth rates for the 1981-1991 period reflect <br />a downward change relative to the growth rates projected last year for the <br />1980-1990 period. During the past seven years the ten-year growth rate <br />projections have been continually decreasing. Figure 2 depicts the <br />region's firm peak load history (1971-1981) and the ten-year projection as <br />of January 1, 1982. Figure 2 also depicts the January 1973, 1976 and 1979 <br />ten-year projections and graphically illustrates the declining projections <br />subsequent to the 1973 oil embargo. Tables 3 and 4 summarize the actual <br />annual firm peak and energy load growth rates for the 1971-1981 period. <br />Figure 2 and Tables 2-4 reflect the effects of the oil embargo, the <br />subsequent and continuing conservation efforts, and the ensuing decrease <br />in actual and forecasted load requirements. All areas except the Rocky <br />Mountain Power Area experienced a significant decrease in annual average <br />compound growth rate for firm peak and/or energy load during the 1973-1981 <br />period as compared to the 1971-1972 period. <br /> <br />The utilities within the WSCC region are taking an active role <br />in promoting conservation and load reduction programs. These efforts <br />coupled with inflation and the increasing price of fuel have provided <br />motivation for reduced load growth. The utilities have recognized these <br />factors by reducing estimates for future power requirements. Prior to the <br />oil embargo, peak load and energy requirements were projected to increase <br />at approximately 7.0 percent per year. The region's current projected <br />average compound growth rates for firm peak and energy loads are 3.4 <br />percent and 3.6 percent per year respectively based on the actual <br />requirements for 1981 and those projected through 1991. Figure 2 <br />illustrates that loads are increasing and are expected to continue to <br />increase, but at a slower rate than that projected before the oil embargo. <br /> <br />Table 5 provides information regarding the ten-year projection <br />for summer and winter peak loads, resources, scheduled maintenance/ <br />inoperable capability and reserve capability for the total WSCC region. <br />The reserves shown for the total WSCC region should not be used to assess <br />the adequacy of power supply within WSCC as transmission constraints may <br />limit interarea capacity transfers. Table 6 is a summary of the projected <br />summer and winter firm peak load growth rates for WSCC and each of its <br />four major areas. The summer and winter seasons are defined as the <br />periods of the year between June 1 and September 30, and between <br />December 1 and March 31, respectively. <br /> <br />A summary of the 1982-1991 firm energy load requirements for <br />WSCC and its four major areas is presented in Table 7. Hydro pumped <br />storage pumping requirements which range from 1,142 GWH to 2,244 GWH per <br />year and interruptible loads which vary from 3,314 GWH to 6,608 GWH will <br />increase the energy requirements above those shown for the WSCC region. <br />Table 8 summarizes the projected energy growth rates. All WSCC areas are <br />projecting an adequate energy supply during the next decade. <br /> <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />1 <br />I <br />I <br />I <br />t <br />I <br />1 <br />I <br />l <br /> <br />10 <br />
