A performance analysis and economic study has been completed of a cavity-type line central receiver and single-axis parabolic cylinder focusing heliostat array for generation of steam for electrical power. A solar thermal power plant was sized to produce 100 MWe at 2:00 p.m. of winter solstice. The system concept is presented. Using the cavity once-through receiver with boiler tubes having an absorptivity of 0.9 and an emissivity of 0.7, it was calculated that total busbar cost in 1976 dollars during the year 1991 the second year at operation, will be 30.27 mills per kilowatt hour. The estimated total capital investment for the 100-MWe plant for the first year of commercial operation is $1908 per kilowatt of capacity.
