Review of Peaking Power Needs in the Pacific Northwest

The study of the Libby Reregulating Project addressed the effect reduced river fluctuations would have on power generation and the sustained peaking adjustment used for the first time in the West Group utilities forecast for 1979 to 1999. The Federal Columbia River Power System consists of a series of 30 dams, each of which has one or more installed hydroelectric generators. Each year the Pacific Northwest Utilities Conference Committee (PNUCC) estimates the region's need for additional power resources. The West Group Forecast summarizes regional loads and resources for 11 future years, while the Long-Range Projection covers a 20-year planning period and presents a more detailed analysis of loads and resources for each major utility in the region.
