This partnership will be the first substantial purchase of wind energy in the U.S. by Wal-Mart.
The deal also represents one of the first sales of power directly from a specific wind project to a major retailer.
Beginning in April 2009, Wal-Mart will purchase electricity directly from Duke's Notrees Windpower Project, located in Ector and Winkler counties, Texas. The project will provide clean, renewable energy to up to 15 percent of 360 Wal-Mart stores and other facilities in Texas.
"We're proud to partner with Wal-Mart on this innovative initiative," said David Marks, Duke Energy Generations Services senior vice president of wind energy. "Our customers want energy products and services that keep them competitive, yet respond to environmental concerns."
The first phase of the Notrees facility will enter commercial operation in December.
This generation capacity is part of the 500 megawatts of wind power Duke Energy will have on line by the end of this year. Duke's Ocotillo Windpower Project, located in Howard County, Texas, began operations in September. When completed in 2009, the Notrees project will provide 150 megawatts of electricity.
