Sierra Pacific Power Company repowering advanced conceptual design. Final technical report, September 30, 1981-June 30, 1982

The advanced conceptual design is given for a tower focus system for repowering a public utility generating unit. The trade studies performed to refine the baseline design are summarized. A system-level description and characterization of the conceptual design is presented, and the major subsytems for the plant are discussed. The major site activities and subsystems of the solar related portion of the plant are: site preparation, site facilities, collector, receiver/tower, master control, fossil energy system, energy storage, electric power generation subsystem, and specialized equipment. Also included is an economic analysis and a development plan. Appended are the system specification, analysis of the optimum unit size, comparison of tilted vs. vertical receivers, receiver tower and receiver control dynamics trade studies, and molten salt property data.
