Louisville Gas and Electric Company and Kentucky Utilities Company, PPL Corporation subsidiaries, have filed a stipulation with the Kentucky Public Service Commission for approval of new natural gas generation units and environmental upgrades, aiming to meet the state's growing energy demands.

Summary

• Louisville Gas and Electric Company (LG&E) and Kentucky Utilities Company (KU) filed a stipulation and recommendation with the Kentucky Public Service Commission (KPSC) on July 29, 2025, regarding proposed future generation-related construction projects and associated accounting matters.
• The stipulation seeks KPSC approval for an approximately 645 MW natural gas combined-cycle combustion turbine (NGCC) generation unit at KU's E.W. Brown Generating Station ("Brown 12"), expected to be available in 2030.
• It also seeks approval for an approximately 645 MW NGCC generation unit at LG&E's Mill Creek Generating Station ("Mill Creek 6"), expected to be available in 2031.
• A selective catalytic reduction (SCR) system at KU's Ghent Generating Station, Unit 2, expected to be available in 2028, is also part of the stipulation.
• Under the agreement, Brown 12 and Mill Creek 6 construction costs would be eligible for AFUDC accounting treatment, the Ghent 2 SCR would be recovered under the existing Environmental Cost Recovery (ECR) mechanism, and Mill Creek 6 costs would be recovered through a new rate tracker mechanism.
• The retirement date for the existing Mill Creek Unit 2 would be extended from 2027 to the in-service date of Mill Creek 6 (2031).
• The proposal to build a 4-hour 400MW (1,600 MWh total) battery electric storage system (BESS) at LG&E's Cane Run Generating Station would be withdrawn without prejudice, with LG&E and KU retaining the right to seek approval for this or similar projects in future regulatory proceedings.
• The original aggregate projected capital expenditures associated with the Companies' proposals were approximately $4.1 billion, including AFUDC, over the 2025 to 2031 period.
• Approximately $2.3 billion of these expenditures were included in PPL Corporation's $20 billion capital plan for 2025 to 2028.
• The Cane Run BESS project represented approximately $0.9 billion of the $2.3 billion, or approximately $0.5 billion in PPL's rate base projection after assumed 40% tax credits.
• PPL Corporation is not modifying its capital plan or rate base projections at this time, as it expects additional investment needs, including transmission investment to support data centers in Pennsylvania.
• PPL plans to update its capital plan and rate base projections in conjunction with its year-end earnings call.
• The stipulation is subject to KPSC approval; a hearing is scheduled to begin on August 4, 2025, with a ruling anticipated during the fourth quarter of 2025.

Sentiment

Score: 7

Explanation: The filing indicates a significant positive step in securing regulatory approval for crucial generation projects, which are essential for meeting growing demand and ensuring future revenue streams. The withdrawal of the BESS project is a minor negative, but the overall capital plan remains robust, and the company retains the option to pursue similar projects later. The agreement with key intervenors reduces regulatory uncertainty.

Positives

• An agreement was reached with several key intervenors, including the Attorney General of the Commonwealth of Kentucky, Kentucky Industrial Utility Customers, Inc., Southern Renewable Energy Association, and the Kentucky Coal Association, Inc., on critical generation projects.
• The stipulation supports the construction of two 645 MW natural gas combined-cycle units (Brown 12 and Mill Creek 6) and a selective catalytic reduction (SCR) system for Ghent Unit 2, which are essential for meeting Kentucky's growing energy needs.
• Costs for the new NGCC units (Brown 12, Mill Creek 6) will be eligible for AFUDC accounting, and Mill Creek 6 costs will be recoverable through a new rate tracker mechanism, ensuring a path for cost recovery.
• The operation of Mill Creek Unit 2 will be extended beyond its previously planned 2027 retirement date until Mill Creek 6 is in-service in 2031, helping to maintain reliability during the transition.
• PPL Corporation is not modifying its overall capital plan or rate base projections at this time, indicating confidence in future investment opportunities despite the BESS withdrawal.
• The agreement reflects the importance of LG&E and KU's role in serving all customers and new economic development load in the lowest reasonable cost manner.

Negatives

• The proposal for a 4-hour 400MW (1,600 MWh total) battery electric storage system (BESS) at Cane Run Generating Station has been withdrawn, although the companies retain the right to refile a separate request in the future.
• The withdrawn BESS project represented a significant portion of the original capital expenditure plan, approximately $0.9 billion, or $0.5 billion in PPL's rate base projection after tax credits.

Risks

• The stipulation remains subject to approval by the Kentucky Public Service Commission (KPSC), and the outcome of the proceeding cannot be predicted.
• Actual results may differ materially from forward-looking statements due to factors such as subsequent phases of rate proceedings and regulatory cost recovery.
• Market demand and prices for electricity and natural gas could impact financial performance.
• Political, regulatory, or economic conditions in states and regions where the Companies conduct business may adversely affect operations and financial results.
• Final negotiated terms and conditions in any prospective contracts and the progress of actual construction, purchase, or installation of assets or operations could differ from current expectations.

Future Outlook

PPL Corporation expects additional investment needs over the current plan period, including further transmission investment to support data centers in Pennsylvania. The company plans to update its capital plan and rate base projections in conjunction with its year-end earnings call. LG&E and KU anticipate a ruling from the KPSC during the fourth quarter of 2025 regarding the stipulation.

Management Comments

• "Kentucky has a very open and transparent regulatory process that allows for customer input and representation, and we appreciate that this process enables thoughtful discussion, opportunities for public input and extensive reviews among the parties involved."
• "As Kentuckys largest regulated utilities, we have an obligation to serve all customers and new economic development load in the lowest reasonable cost manner. This agreement reflects the importance of that role and the critical needs addressed in our long-term generation investment plans."
