COLUMBUS - Columbus-based Cummins Inc. (NYSE: CMI) is expanding a wind farm in northern Indiana. The company says, when fully operational, the farm will generate renewable energy equal to the amount Cummins uses at its Indiana facilities.

The expansion will add 75 megawatts of capability to the plant, which is enough to power about 20,000 average Indiana homes. The Meadow Lake Wind Farm complex currently has a capacity of 600 megawatts. The expansion is the result of a virtual power purchase agreement with EDP Renewables North America.

Cummins Executive Director of Worldwide Environmental Strategy and Compliance says the project is part of the company's strategy "to provide clean, fuel-efficient and dependable power for our customers with the least environmental impact possible." He says it plays into an ongoing effort to reduce greenhouse gases, which is the company's largest environmental impact.

The company's Environmental Sustainability Plan includes a goal to reduce "energy intensity" by 32 percent by 2020, compared to 2010 levels.
