10 MWe solar thermal central receiver pilot plant total capital cost

ABSTRACT:
This report provides a detailed breakdown of the capital cost of the 10 MWe Solar Thermal Central Receiver Pilot Plant located near Barstow, California. The total capital requirements of the pilot plant are given in four cost breakdown structures: l} project costs (research and

development, design, factory, construction, and start-up); 2} plant system costs (land, structures and improvements, collector system, receiver system, thermal transport system, thermal storage system, turbine-generator plant system, electrical plant system, miscellaneous plant equipment, and plant level); 3} elements of work costs (sitework/earthwork, concrete work, metal work, architectural work, process equipment, piping and electrical work); and 4} recurring and non-recurring costs. For all four structures, the total capital cost is the same ($141,200,000; however. the allocation of costs within each structure is different. These cost breakdown structures have been correlated to show the interaction and the assignment of costs for specific areas. The detailed breakdown structure presented here for an actual solar facility can be useful in the understanding of the costs of future central receiver plants, and may serve as a basis for standardizing the categories of plant costs. The costs of the pilot plant cannot be scaled directly to larger future plants due to the developmental nature of the pilot plant.
