General Motors has taken a number of significant steps to make their vehicles greener, and they are doing similar things with their manufacturing plants, as well. This week, the company has made two announcements about using rooftop solar arrays to power its manufacturing facilities.
The Detroit–Hamtramck plant, which produces the Chevy Volt, will be having a 516 kilowatt solar array installed on six acres of land on the south side of the plant as part of a cooperative venture with the local electrical utility company, DTE. Using power from the solar array is expected to save GM $15,000 per year.
A Toys “R” Us distribution facility in New Jersey will soon be home to the largest solar rooftop installation in the country. The huge installation will feature 37,000 solar panels producing 5.38 MW of power.
Toys “R” Us has entered into a 20-year power purchase agreement with the Constellation Energy Group — the builders of the project — and will meet 72 percent of the facility’s energy needs with the solar power system. The facility’s carbon footprint will be reduced by 4,569 tons.
The European Commission has granted 49.06 million euros ($69.99 million) in aid to the joint venture of Sharp Corporation, Enel Green Power SPA, and STMicroelectronics for photovoltaic investment in eastern Italy.
The plant will produce thin-film PV modules with a projected 240 megawatts per year production capacity. It’s completion is expected by the end of 2012.
