DOE finalizes $337 million loan guarantee to Mesquite Solar 1 for solar power plant

The optimized 150 MW alternating current photovoltaic solar generation project will be located in Maricopa County, Arizona, about 45 miles west of Phoenix

Washington, D.C., September 29, 2011 — U.S. Energy Secretary Steven Chu announced that the Energy Department finalized a $337 million loan guarantee to Mesquite Solar 1, LLC to support the development of a photovoltaic solar generating project.

The optimized 150 MW alternating current photovoltaicsolar generation project will be located in Maricopa County, Arizona, about 45 miles west of Phoenix. Sempra Energy, the project sponsor, estimates the project will fund up to 300 construction jobs.

The Mesquite Solar 1 Project will be one of the first utility-scale PV power plants in the country to use U.S.-manufactured, innovative transformer-less and liquid cooled inverter technology. The technology allows for improvements in energy output, a decrease in operating costs and improved reliability.

The facility will avoid the emissions of over 200,000 metric tons of carbon dioxide annually. The project is anticipated to generate nearly 350,000 MWh of electricity in the first full year of production, or enough to power nearly 31,000 homes. This generation project is supported by a power purchase agreement to sell power to the Pacific Gas & Electric Co.
