SWPG sold the project to Luminant in 2005. The project was retired and decommissioned in 2018.
Campo Verde Solar
140 MW
SWPG and its affiliate MMR Power Solutions, in partnership with Bethel Energy, developed a 140 MW AC solar energy project located near El Centro in Imperial Valley, CA. Originally a solar thermal project with a biomass component, SWPG/MMR revised the project concept from solar thermal to solar PV. The project commenced operating in 2013. SWPG/MMR sold the project to First Solar in 2011 who completed development and built the project.
