LG&E and KU to replace coal units with new gas turbine at Mill Creek, modernizing energy fleet.

Louisville Gas and Electric Co. and Kentucky Utilities Co. (LG&E and KU) are preparing to replace two coal generation units at Mill Creek Generating Station in Kentucky with a 645-MW GE Vernova hydrogen-ready 7HA.03 gas turbine. The new natural gas combined cycle plant, Mill Creek Unit 5, will be built by TIC (The Industrial Company), a subsidiary of engineering and construction giant Kiewit. This move is part of a plan to modernize the utilities’ 8-GW fleet. The utilities currently operate 11 coal units, including units with a total net summer capacity of 4,867 MW, a 662-MW natural gas unit, and 17 load-following simple cycle combustion turbine (SCCT) peaking units with combined capacity of 2 GW. However, in 2022, they moved to retire four of their 11 coal generating units: Mill Creek 1 in 2024, Mill creek 2 in 2024; the 412-MW Brown 3 in 2028, and the 485-MW Ghent 2 in 20 28. Despite these requests, the Kentucky Public Service Commission (KPSC) has denied them.
