A focusing collector thermal-electric power plant has been erected in Corsica (France). This plant consists of a field of 1176 m2 fixed mirror concentrators, producing heat at 250° C, a stratification thermal energy storage of about 1250 kWh, two power conversion units of 45 kWe each, with a supersonic turbine expanding a heavy organic working fluid, and two cooling towers of 200 kW each. This full-scale prototype has been built mainly to demonstrate the capability of the distributed collector solar plant concept, in the power range from 50 kWe to 1000 kWe, and the temperature range from 150 to 300° C. This paper describes the conceptual design and the performance of the plant, and discusses problems that were met during construction.
