Maryland's Largest Single Rooftop Solar Power Installation Unveiled at Staples Fulfillment Center in Hanover
The 1.01 Megawatt Solar System Provides Power Equal to that Used by More Than 100 Homes Annually
HANOVER, Md., Jan 06, 2010 (BUSINESS WIRE) -- Staples (NASDAQ: SPLS), the world's largest office products company and SunEdison, North America's largest solar energy services provider and a subsidiary of MEMC Electronic Materials (NYSE: WFR), hosted a dedication ceremony today to unveil the largest single rooftop solar power installation in Maryland at Staples' 200,200 square foot fulfillment center in Hanover. The 1.01 megawatt solar installation covers nearly 175,000 square feet of roof space, larger than three football fields.

The environmental savings associated with the system will offset more than 43 million pounds of carbon dioxide (CO2) over 20 years, equivalent to removing CO2 produced by more than 4,200 automobiles driving 12,000 miles per year. The zero-emission, silent photovoltaic system will generate approximately 1.2 million kilowatt hours (kWh) of electricity per year, and 21 million kWh during the initial 20 years of the project. The solar installation was financed, built and maintained under a power purchase agreement (PPA) with SunEdison. Under the PPA, Staples will purchase the electricity produced for the term of the contract.

"The solar power system installed at our Hanover fulfillment center is the latest example of Staples' ongoing commitment to environmental leadership," said Mark Buckley, vice president of environmental affairs for Staples. "Through our relationship with solar services provider SunEdison, we are able to purchase solar energy from our rooftop at a rate below or equal to the cost of electricity from the grid. This reduces our operating costs while freeing up more electricity during peak times for use by local homes and businesses."

"We are proud to be a long time partner of Staples in providing economical solar solutions to meet their energy needs and commitment to the environment," said Carlos Domenech, President of SunEdison. "SunEdison continues to be an industry leader by combining cutting edge technologies with our unique project finance capabilities to enable large-scale development of solar."

"EPA applauds Staples for initiating this solar energy project to power its Hanover facility," said Shawn M. Garvin, administrator for the EPA's mid-Atlantic region. "I hope this work inspires other companies to use energy in a manner that does not contribute to global climate change. Staples is demonstrating the kind of leadership that is needed to reduce greenhouse gases and move our nation into a clean energy future."
