Advanced Energy Lands Second-Phase Contract for Expanded 6 MW Solar Plant

Company’s Award-Winning Solaron^® PV Inverters Provide Lowest LCOE

FORT COLLINS, Colo., Feb. 2, 2010—Advanced Energy Industries, Inc. (NasdaqGM: AEIS), today announced that it has been awarded the second-phase contract for a newly expanded 6 MW solar plant installed at Aerojet’s corporate headquarters in Sacramento, CA. The Solaron PV inverters were selected by Solar Power, Inc. for the expansion because of their industry leading efficiency ratings, as well as their ability to deliver maximum power and lowest LCOE (Levelized Cost Of Energy).

Dr. Hans Betz, chief executive officer of Advanced Energy, noted, “This expansion demonstrates the major strides that leading energy companies are making in accelerating the deployment of renewable energy solutions. Advanced Energy’s industry-leading technology and comprehensive support services have enabled us to provide compelling benefits to our customers in the commercial and utility markets.”

After the successful commissioning of the original 3.6 MW site in November, Solar Power, Inc. announced a 2.4 MW expansion, bringing the total capacity of the site to 6 MW. The expansion is expected to be completed in April 2010, and will make the Aerojet site the single largest industrial installation in the State of California, and one of the largest in the U.S. Electricity generated from the new site will provide just over 10 percent of electricity demand for the Aerojet facility, as well as provide clean, solar energy to the greater Sacramento district. The project was developed in partnership with Solar Power, Inc. as well as with Aerojet, the Sacramento Municipal Utility District (SMUD) and HEK, LLC.
