Kentucky Utilities and Louisville Gas and Electric Co. will ask the state Public Service Commission for permission to buy electricity generated by wind power in Illinois, and to pass the increased cost to customers.
If the PSC agrees, 109.5 megawatts would be produced at the Grand Ridge Energy Wind Center in LaSalle County, Ill.
Grand Ridge won a competitive bid process to supply wind energy for 20 years at a cost that is 5 to 6 cents higher per kilowatt hour than the company's current cost.
It costs 2 or 3 cents to produce a kilowatt hour at a coal-fired plant, spokeswoman Chris Whelan said.
KU and LG&E, which have the same parent company, already produce 109 megawatt hours of electricity at hydroelectric plants on the Ohio River and at Dix Dam on Lake Herrington.
The wind proposal will go to the PSC Sept. 28.
