Advanced Energy® Solaron® PV Inverters Selected for San Francisco Sunset Reservoir 5 MW Solar Project

Industry-Leading Efficiency Ratings and Lowest LCOE Fuel Momentum for Solaron

FORT COLLINS, Colo., Feb. 11, 2010—Advanced Energy Industries, Inc. (NasdaqGM: AEIS), today announced its Solaron® PV inverters have been selected to power the San Francisco Sunset Reservoir 5 MW solar project. The project was awarded to Advanced Energy by Recurrent Energy, an independent power producer and a leading developer of solar power projects. Recurrent Energy will own and operate the solar power system, and is developing the project in partnership with the San Francisco Public Utilities Commission. The Solaron PV inverters were selected due to their record-setting efficiency ratings, field-proven LCOE (Levelized Cost Of Energy) advantages, and Advanced Energy’s outstanding customer service.

Dr. Hans Betz, chief executive officer of Advanced Energy, noted, “We are proud to be selected by Recurrent Energy to collaborate with them on this landmark project. Advanced Energy’s Solaron PV inverters have a strong reputation for optimized efficiency and the highest level of reliability for large-scale utilities. The project demonstrates the City of San Francisco’s commitment to renewable energy, and we are pleased to be able to help them achieve their goals.”

The 5 MW solar plant is being constructed on the roof of San Francisco’s largest reservoir, located in the city’s Sunset district. Construction is scheduled to begin this winter and is expected to be completed in 2010. Upon completion, the project will consist of 25,000 solar panels that span approximately 12 acres, making it one of the country’s largest municipal solar projects. The system will more than triple the City’s available renewable energy which can be used at numerous municipal facilities, including the San Francisco Airport, MUNI light rail system, the General Hospital and city schools.
