A <br />summary of the lDad and resource data is repDrted in this sectiDn. <br /> <br />Beginning with Figure 1 on page 14, the information presented <br />herein via tables and figures summarizes load and resource information for <br />the WSCC region. Additional information follows for each of the four <br />major areas within WSCC--Northwest Power Pool Area (NWPP), Rocky Mountain <br />PDwer Area (RMPA), ArizDna-New Mexico Power Area (AZ-NM) and California- <br />Southern Nevada Power Area (CA-SNV). IntrDducing the data for each area <br />is a map Df the area, a list of organizations within that area which have <br />been assigned a code fDr data collection (some of these organizations <br />collect data from smaller organizations in the area), and a figure <br />depicting the area's lDad and resource history (1972-1982) and current <br />ten-year projection (1983-1992). The data which were used in plotting the <br />historical lDad and resource curves are included in the Appendix. <br /> <br />Table 1 summarizes the 1982 actual monthly load and resource <br />data fDr the WSCC region and provides a comparisDn with the total peak and <br />energy loads that were prDjected as of January I, 1982. The WSCC 1982 <br />non-coincidental peak demand Df 84,066 MW which Dccurred in January <br />represents a 0.1 percent increase cDmpared with the 1981 calendar peak <br />demand of 83,966 MW which occurred in August. The 1982 summer peak demand <br />of 80,446 MW occurred in September and was 4.2 percent below the 1981 <br />summer peak demand and 7.7 percent belDw the prDjected 1982 summer peak <br />demand. The calendar 1982 peak demand was 0.1 percent belDw that <br />forecasted for January. Installed generating capacity at the time of the <br />January peak was 117,968 MW. <br /> <br />The WSCC non-coincidental peak demand occurred during the winter <br />months in the calendar years 1978, 1979 and 1982 due to the extremely cold <br />temperatures experienced throughDut the WSCC region. Winter weather <br />conditions experienced during 1980 and 1981 were less severe than the <br />Dther years. The calendar 1982 winter peak demand of 84,066 MW which <br />occurred in January was 6.9 percent greater than the calendar 1981 winter <br />peak demand due to the cold weather and associated increased peak demand <br />experienced within the NDrthwest PDwer PDol Area (see Figure 6). Winter <br />weather conditiDns during late 1982 and early 1983 were generally milder <br />than the previous winter season contributing tD a reductiDn in winter peak <br />demands in most areas of the WSCC region. <br /> <br />The 1982 total net energy requirement reported for the WSCC <br />region (496,801 GWH) was 2.0 percent less than the repDrted 1981 tDtal net <br />energy requirement (506,807 GWH). The 1982 energy requirement fDr the <br />region was 5.8 percent below that forecasted for the year. Actual loads <br />which were lower than projected are indicated in the tables by negative <br />forecast deviations. The negative forecast deviations reflect the effects <br />of conservation efforts, the eCDnomic climate and mild summer weather <br />experienced in the West during the year. <br />
