Louisville Gas & Electric and Kentucky Utilities Co. plan to retire three coal-fired power plants representing 801 MW of generation over the next several years and will replace them with natural gas-fired generation, according to platts.com.
In an integrated resource plan filed with the Kentucky Public Service Commission, the utilities say they are considering closing the 563 MW Cane Run, 163 MW Green River and 75 MW Tyrone coal-fired plants to comply with U.S. Environmental Protection Agency requirements rather than retrofit them with advanced pollution controls, the article said.
The utilities state in the article that the fuel switch and retrofitting other coal-fired power plants could increase customers’ bills by as much as 20 percent.
Cane Run became one of the first plants in the U.S. to be equipped with a scrubber to cut sulfur dioxide emissions, but the plant, along with Green River and Tyrone, is unable to cut its mercury emissions.
Two of Tyrone’s three turbines were previously shut down and the third is temporarily mothballed.
The closures are not related to the purchase of parent company E.ON US in 2010 by PPL Corp.
