Baltimore, Maryland – General Motors has announced that it will add a 1.2-megawatt solar power installation to the roof of its transmission plant in White Marsh, Maryland. The system will be deployed under an agreement with solar energy services provider SunEdison, which will finance, install, operate and maintain the system.

When fully operational in the third quarter of 2009, the system will be one of the largest solar rooftop installations on the east coast. It will consist of more than 8,700 solar panels and will sit on approximately 300,000 square feet of roof space.

The installation will generate about 1.4 million kWh of clean renewable solar energy, equivalent to the demand of about 140 to 150 U.S. households. The installation will enable GM to displace about 20 per cent of the plant’s current power purchased from the local utility.

The White Marsh plant reached landfill-free status in 2007, as it no longer sends any production waste to local landfills but recycles or reuses it. It is also GM’s first global manufacturing facility to operate landfill-free and have a solar power installation.

GM currently has two of the largest solar power installations in the U.S. on the roofs of its Rancho Cucamonga and Fontana, California parts warehouses, and upon completion this year, it will also have the world’s largest solar power rooftop installation at its assembly plant in Zaragoza, Spain.
