Estimating the Value of Utility-Scale Solar Technologies in California Under a 40% Renewable Portfolio Standard

Posted: June 11, 2014 - 01:02 / NREL / Reports

With growing interest in renewable energy, the penetration of solar photovoltaics (PV) and wind generation is likely to rise. Accommodating the time-varying and uncertain output of these resources will be a challenging aspect of integrating large-scale renewable energy into the electric power system. Concentrating solar power (CSP) with thermal energy storage (TES) is a unique source of solar energy in that its output can be shifted over time and also controlled in response to system operator signals, allowing for provision of a wide range of grid services. The ability of CSP-TES to be a flexible source of renewable generation may be particularly valuable in regions with high overall penetration of solar energy, such as the state of California.
