Solar Electric Generating Station I
This page provides information on Solar Electric Generating Station I, a concentrating solar power (CSP) project, with data organized by background, participants, and power plant configuration.
SEGS I is one of the nine Solar Electric Generating Station plants in California’s Mojave Desert. The combined electric generating capacity of these plants, which use parabolic trough technology, is more than 350 megawatts. The plants operate as Qualifying Facility Independent Power Producers under the Public Utility Regulatory Policies Act, with a special Standard Offer 2 type of power purchase agreement to Southern California Edison. Initially, the entire plant had three hours of thermal energy storage for dispatching electricity during periods of peak demand. However, a fire in 1999 damaged the storage system and it was not replaced.
