The Rice Solar Energy project will utilize molten salt thermal storage, which will allow it to produce electricity after the sun has set or during cloudy periods.
The California Public Utilities Commission (CPUC) has approved an amended power purchase agreement (PPA) between Pacific Gas & Electric Company (PG&E, San Francisco, California, US) and SolarReserve LLC (Santa Monica, California, US) for the Rice Solar concentrating solar power (CSP) project.
The amended PPA changes the point of grid interconnection, as well as extending the guaranteed operation date to June 1st, 2016 and changing payment provisions. The plant was originally expected to begin operations by October 1st, 2013.
The 150 MW Rice Solar CSP plant will be based on a concentrated solar power tower design with molten salt storage, located in Rice, San Bernardino County, California.
Under the amended PPA, Rice Solar will connect to the Western Area Power Administration’s (WAPA) Mead substation, instead of the California Independent System Operator. The PPA also changes payment provisions to mitigate any pricing risk associated with a change in the point of interconnection.
