Duke Energy Carolinas wants to purchase up to 500 MW of wind power by 2022, according to reports.
The unit of Duke Energy issued this request for proposals for new or existing wind farms to deliver wind power to the Duke transmission grid.
The cost of wind power is falling, making this an excellent time to bring more wind power to customers in the Carolinas, Rob Caldwell, president of Duke Energy Renewables and Distributed Energy Technology, said in a news release.
Duke already owns 35 solar power projects in the region, but this would be the utility's first wind power purchase agreements.
In 2007, North Carolina signed a renewable energy portfolio standard into law, which mandates the company generate 12.5 percent of its retail sales in the state by renewable energy or energy efficiency programs by 2021, and continuing afterward.
