Solar Central Receiver Prototype Heliostat. Volume III. Cost Estimates

摘要

The Boeing heliostat design can be produced and installed for a Capital Cost of $42 per square meter at high commercial plant quantities and rates. This is 14% less than the DOE cost target. Even at a low commercial plant production rate of 25,000 heliostats per year the Capital Cost of $48 per square meter is 2% less than the cost goal established by the DOE. Projected capital costs and 30 year maintenance costs for three scenarios of production and installation are presented: (1) commercial rate production of 25,000, 250,000, and 1,000,000 heliostats per year; (2) a one-time only production quantity of 2500 heliostats; and (3) commercial rate production of 25,000 heliostats per year with each plant (25,000 heliostats) installed at widely dispersed sites throughout the Southwestern United States. These three scenarios for solar plant locations and the manufacturing/installation processes are fully described, and detailed cost breakdowns for the three scenarios are provided.
