Solar Electric Generating Station II
This page provides information on Solar Electric Generating Station II, a concentrating solar power (CSP) project, with data organized by background, participants, and power plant configuration.
SEGS II 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.
