The three best regions for marketing a solar hybrid plant were studied. These are: East South Central, Rocky Mountain, and Pacific regions. The base load and intermediate load markets appear to be approximately 90 giga watts. The economic analysis made by SRI shows that a coal fired hybrid plant is economically competitive with pure coal plants for fuel escalation rates above 9% per year. For example: at 10% per year escalation the hybrid plant BBEC is 67 mils/Kwh compared to 70.7 mils/Kwh for a typical coal plant. The optimization studies conducted by McDonnell Douglas on the field geometry, tower height, and receiver dimensions are converging on an optical tower height of 120 m, 7332 heliostats and a receiver which is 10 m in diameter and 12 m high. One more iteration should fix the optical geometry for the 100 MWe plant with a solar multiple (S.M.) of 0.8. The preliminary values of the performance and design data sheets for the 100 MWe 0.9 S.M. hybrid base line plant have been prepared.
