PPL Lifts Capex to $25 Billion for 645-MW Kentucky Gas Plant

PPL Corporation raised its four-year capital plan to $25 billion on Nov. 6, a $2 billion increase driven largely by a new 645-megawatt (MW) combined-cycle gas plant in Kentucky. The unit would start running in the second quarter of 2032, pending state approval.

The Allentown, Pennsylvania-based utility announced the increase on its third-quarter earnings call. Its Kentucky subsidiaries, Louisville Gas and Electric (LG&E) and Kentucky Utilities (KU), will build the plant. A combined-cycle unit generates electricity with a gas turbine and recovers waste heat through a steam turbine, raising thermal efficiency above simple-cycle designs.

What does the new plan contain?

The numbers anchor the announcement:

• $25 billion: PPL's new four-year capital plan, up $2 billion from the prior plan.
• 645 MW: nameplate capacity of the planned combined-cycle unit.
• Q2 2032: targeted startup, subject to state regulatory approval.
• Four plants: the number of new gas-fired combined-cycle units LG&E and KU have planned since 2022.

PPL attributed most of the $2 billion increase to the new Kentucky unit. The plan's horizon runs four years from the Nov. 6 announcement.

Who is building it?

LG&E and KU, PPL's regulated Kentucky subsidiaries, will own and construct the plant. The project marks the fourth new gas-fired combined-cycle plant the two utilities have planned since 2022, a sustained build-out of dispatchable thermal capacity in the state.

The unit still needs approval from Kentucky state regulators before construction proceeds. That permitting step sits between the announcement and any final investment decision on schedule.

Why gas, and why now?

PPL framed the capacity around data-center demand. The company announced the plant explicitly for data-center load growth in its service territory, a demand driver utilities across the country cite for new gas-fired generation.

CEO Vince Sorgi said he does not expect the 645-MW unit to be the last new gas plant the utilities plan. His comment signals continued capital deployment into Kentucky gas generation beyond the current four-year window.

What is the watch item?

The Kentucky regulatory docket is the gating item. State approval determines whether the Q2 2032 startup date holds, and any further gas units Sorgi hinted at would face separate dockets in later years. Ratepayers and industrial customers, including data-center operators, will watch how the Kentucky Public Service Commission treats the request.
