Project Datasheet Agua Caliente Solar Project Yuma County, Arizona, USA NRG Energy & MidAmerican Renewables, LLC. Developer/ First Solar Construction/O&M: Size: Power Output For: ~100,000 average homes per year CO 2 Displacement: ~220,000 metric tons per year* (~40,000 cars o the road) Project Timeline 2008-2009 Planning Permitting Construction Operation 290MW of clean, renewable power Located on 2,400 acres of previouslydisturbed farm land Approximately 400 construction jobs created Panels recycled after useful lifespan Minimal noise The project has secured all necessary permits to commence construction, including a certificate of environmental compatibility from the Arizona Corporation Commission and a conditional use permit from Yuma County. Transmission access will be provided by the existing Hassayampa-North Gila 500 kilovolt transmission line adjacent to the site. A new regional switchyard proposed by the transmission owners will be constructed on the site and be in service by winter 2011/2012. No water used during electricity generation First Solar is constructing a 290 megawatt (MW) solar project located on 2,400 acres of previously-disturbed farmland in Yuma County, Arizona near the communities of Dateland and Hyder. The Agua Caliente Project, initially developed by NextLight Renewable Power, LLC., is now being completed by First Solar which acquired NextLight on July 12, 2010. On August 5, 2011, NRG Energy acquired the Agua Caliente project and on January 18, 2012, MidAmerican Renewables, LLC acquired a 49% stake in the project. First Solar will continue to build, operate, and maintain the project. When fully operational, the project will generate enough clean solar energy to serve the needs of about 100,000 average homes per year, displacing approximately 220,000 metric tons of carbon dioxide (CO2) annually—the equivalent of taking about 40,000 cars o the road. Pacific Gas & Electric Company has contracted to purchase the project’s output for 25 years. * CO2 displacement based on PG&E grid 01761_DS_NA_19OCT12 | © Copyright 2012, First Solar, Inc.
