Kentucky is about to retire two coal generation units.

The Kentucky Public Service Commission will let Louisville Gas and Electric and Kentucky Utilities retire the units at their plant in southwestern Louisville.

The units were made in the 1970s and the companies say they have outlived their useful life.

LG and NQ will build a natural gas unit.

John Crockett, president of both companies, said, quote, We put forth the least cost plan to continue serving our customers in a safe and reliable manner.

End quote.

The companies had to prove to the commission that customers won't be charged more or go without reliable energy.

Kentucky lawmakers, led by state Senator and Lieutenant Governor candidate Rob Mills, passed a law this year that require utilities to get state approval to retire coal units.

Mills testified against the utilities in September.

His running mate, Republican gubernatorial candidate Daniel Cameron, issued a statement saying, quote, The fight to protect Kentucky coal continues to those who have been victimized by the anti-coal agenda.

I am more determined than ever to fight for you and quote the utility's hope to retire more coal units and Trumbull and Mercer County.

The commission declined those requests.
