VALUE OF CSP

The value of CSP was determined by adding a relatively small amount of generation to the base system and evaluating the change in production costs and the value of system capacity. We also examined the operation of CSP with TES, including how energy was shifted over time. Several technologies were evaluated; for uniform comparison, each technology provided an approximately equivalent amount of energy, based on the an­nual production of a 300-MW CSP/TES plant with a solar multiple of 2.0. This is about 1,070 GWh, or enough to provide about 1.4% of the test system demand.
