Add to ORKGa 417 megawatt thermal electric generating station, is considered the most economic installation. The capital cost of the water unit is estimated to be $86,000,000. The powerplant costs which may be provided by private power companies are $53,500,000 for a gas-fired unit and $65,000,000 for a coal-fired unit. For the purpose of analysis, the unit cost of water was determined for plants located on the California coast. The gas-fired plant produced water at a plantside cost of about $105 per acre-foot, and the coal-fired plant produced water at a plantside cost of about $90 per acre-foot. The experience gained by constructing and operating intermediate size plants should serve to decrease these unit cost values. Technological advances as a r...
