Kentucky Utilities may not be as bright as the blue moon of Kentucky, but it still shines bright on those in the Bluegrass State. The company, founded in 1912, was a subsidiary of E.ON U.S.  It generates and distributes electricity to more than 485,250 industrial and residential customers in a 6,600 square mile area in Kentucky. The company's Old Dominion Power serves about 30,000 customers in five Virginia counties. Kentucky Utilities has a total generation capacity of approximately 4,570 MW.  In 2010 E.ON U.S. was acquired by PPL as that company consolidated its holdings in the region.
