英文摘要	California has endured severe droughts both in 1976 and 1977. As a consequence, surface-water supplies during 1977 decreased to levels not experienced in the recent history of California. Hydroelectric supplies, which rely on surface runoff, also decreased to record lows raising questions regarding the adequacy of electricity supplies to meet summer peaks during 1977 and 1978. Through 1977 electricity supplies, aided by conservation of electricity by consumers, power pooling, and other measures were adequate to meet demand. However, supplies were more expensive due to increased reliance on thermal generation to compensate for hydroelectric losses. The continuance of the drought for another year is analyzed in this study. To analyze the impact of supply options on reliability and electricity prices, two separate models were modified and implemented. These models along with the overall methodology, although implemented primarily with data for 1978, would be generally applicable for analyzing the adequacy of electricity supply during any year. In this analysis, electricity demand and supply during 1977 are reviewed before analyzing the prospective situation during 1978. Hydroelectric supplies for 1978 are assumed at the level anticipated by the electric utility companies. These supply estimates are based on the 1977 levels of runoff. The hydroelectricity thus generated would be slightly lower than that estimated for 1977. Also on the supply side, because of the uncertainty associated with the introduction of the Diablo Canyon 1 nuclear power plant, the supply options with and without Diablo Canyon Unit 1 are analyzed. The major findings of the study are discussed.
