Kentucky power companies Louisville Gas and Electric and Kentucky Utilities said on Friday new, stricter, federal environmental regulations will force them to retire three older, coal-fired power plants and recoup the $4 billion in EPA compliance costs through future price hikes for customers.

The three Kentucky plants being shut down supplied less than 800Mw of power. One megawatt powers about 1,000 homes.
