are confirmed or further fine-tuned upon actual meas- 

 urements. Southern California Edison at their two 

 megoMatt capacity Solar Photovoltaic PoHer Plant at the 

 Lugo Substation in California has used days in advance 

 satellite photos to predict solar-fuel availability and 

 dispatchabllity , days in advance. 



The following Table shows the potential monthly and 

 annual generation from a 1000 flegawatt-gross maximum 

 capacity Solar Voltaic Generation Plant at any of 

 twenty-five locations in the Pacific Northwest. Also, 

 generation is shown for the Solar Voltaic Generation 

 Plant if placed at Daggett or Sacramento in California. 

 This is generation for a Flat-Plate array with the 

 Solar Voltaic Unit Generator panels tilted at the 

 angles shown (approximating the site Latitude). The 

 Annual Insolation and the Annual Fuel Dependent 

 Capacity Factors are shown; approximating the Plant 

 gross annual capacity factor if all of the solar 

 derived generation is dispatched. Orientating these 

 annual SVG PLANT capacity factors, the hydro-electric 

 portion of BPA's resources operates at about 32X gross 

 annual capacity factor, about a third of the energy 

 that could be produced if all of the turbine-generators 

 had water to operated at full capacity around the clock 

 all year.
