AEP Closes on Transmission Investment Strategic Partnership with KKR and PSP Investments

KKR and PSP Investments have jointly acquired a 19.9% equity interest investment in AEP’s Ohio and Indiana Michigan transmission companies.
The transaction proceeds will be used to support AEP’s five-year, $54 billion capital plan.

COLUMBUS, Ohio, June 5, 2025 - American Electric Power (Nasdaq: AEP), KKR and PSP Investments have completed the transaction announced in January 2025 for KKR and PSP Investments to jointly invest $2.82 billion for a 19.9% equity interest in AEP’s Ohio and Indiana Michigan transmission companies. The 19.9% minority equity interest represents approximately 5% of AEP’s total transmission rate base.
More than 20 gigawatts of new power demand is expected across AEP’s footprint by the end of the decade. In addition, AEP continues to see further interest from almost 600 new and existing customers representing nearly 180 gigawatts of energy demand looking to connect to AEP’s transmission system. This strategic partnership will enable further infrastructure development to support the growth opportunities in AEP’s Indiana, Michigan and Ohio service territories. AEP will continue to operate and maintain these transmission facilities.
“AEP built the nation’s largest transmission grid, and our position as an industry leader in the transmission space enabled us to attract world-class partners like KKR and PSP Investments that have a history of investing in and developing vital infrastructure projects,” said Bill Fehrman, AEP president and chief executive officer. “Our customers and communities will benefit from the initial investment, which supports the execution of our five-year, $54 billion capital plan, and this strategic partnership will facilitate ongoing investment in the critical infrastructure needed to support our customers and enhance reliability in Indiana, Michigan and Ohio.”
“We are honored that AEP has entrusted us to support their efforts to modernize their transmission systems in order to better meet increased customer demand and further enhance grid

reliability,” said Kathleen Lawler, managing director, KKR. “We look forward to working closely alongside PSP Investments to bolster AEP’s commitment to providing communities with reliable, affordable power.”
“PSP Investments is pleased to strategically partner with AEP to support its ambitious growth plan that will reinforce its position as an industry leader in the transmission space,” said Michael Rosenfeld, managing director, Infrastructure Investments, PSP Investments. “We look forward to participating in the development of critical transmission infrastructure in some of AEP’s fastest-growing service territories and are excited to embark on this journey alongside KKR.”
