SunEdison Awarded Additional 31 MW (AC) of Solar Projects by the Ontario Power Authority

TORONTO, Feb. 25, 2011 /PRNewswire/ -- SunEdison, a leading worldwide solar energy services provider and a subsidiary of MEMC Electronic Materials, Inc. (NYSE: WFR), has been awarded 31 Megawatts (MW) AC of solar photovoltaic (PV) projects by The Ontario Power Authority (OPA) as part of the province's landmark Feed-in Tariff (FIT*) program. This recent announcement adds to the 28 MW of ground-mount and rooftop solar projects already deployed by SunEdison in Ontario.

With more than 390 solar deployments worldwide, SunEdison will leverage our global experience to finance, build, operate, monitor and maintain the additional five photovoltaic solar energy systems in Ontario. Located in communities across the province including Mississauga, Whitby, Drummond, Rideau Lakes and Ingleside, the projects will generate over 47 million kilowatt hours (kWh) of clean energy in the first year of operation and produce over 873 million kWh over 20 years. That is enough energy to power more than 76,000 average Canadian homes for one year.

"As a leading worldwide provider of solar energy services, SunEdison has the experience and capabilities required to play a pivotal role in building Canada's renewable energy industry," said Jason Gray, Canada Country Manager for SunEdison. "We believe that solar energy is a key component of the province's energy mix and that by working closely with government and business partners, we can create jobs, generate green power and ensure a sustainable renewable energy sector for Ontario."

SunEdison was awarded two (2) 10 MW projects in Rideau Lakes, one (1) 10MW project in South Stormont, one (1) 500kW project in Mississauga, and one (1) 500kW project in Whitby.
