Weber, E. R.

The conceptual design of a solar thermal central receiver repowered gas/oil fired steam-Rankine electrical power generation plant based on a central receiver using a molten salt (60% NaNO/sub 3/, 40% KNO/sub 3/, by wt) for repowering the No. One Unit of APS's Saguaro power plant is described in detail. The plant is located 66 km (41 mi) north of Tucson, Arizona. The selection of both the site and the molten salt central receiver promotes a near-term feasibility demonstration and cost-effective power production from an advanced solar thermal technology. The recommended system concept is to repower the existing electric power generating system at the maximum possible level (120 MW/sub e/ gross) using a field of 10,500 second-generation (49 m/sup 2/) heliostats and a storage capacity of 3.8 hours to be used for optimum dispatch of power to the utility system. The total project construction cost is estimated to be 167 million in 1980 dollars. The plant will be capable of displacing fossil energy equivalent to 4.9 million barrels of No. 6 oil in its first 10 years of operation. Detailed subsystem characteristics, an economic analysis, and a development plan are presented in detail. (WHK)
