About

PPL Corporation is an Allentown, Pennsylvania-based regulated electric utility holding company — publicly traded on the New York Stock Exchange (NYSE: PPL) as an S&P 500 Utilities component — delivering electricity and natural gas to approximately 3.5 million customers across Pennsylvania, Kentucky, and Rhode Island through four regulated utility subsidiaries: PPL Electric Utilities (Pennsylvania), Louisville Gas and Electric Company (Kentucky), Kentucky Utilities Company (Kentucky), and Rhode Island Energy (acquired from National Grid in 2022), through approximately 7,200 employees. PPL's most significant strategic development is its dramatically expanded capital investment plan: in 2025, the company announced a $20 billion infrastructure investment program from 2025 through 2028 — a 40% increase over its prior $14.3 billion capital plan — expected to generate 9.8% average annual rate base growth through 2028. The enhanced investment drives PPL's reaffirmed 6-8% annual EPS and dividend growth targets through at least 2028, making PPL one of the highest-growth profiles among large regulated utilities. CEO Vincent Sorgi has executed the transformation from PPL's former international utility operations (selling UK operations in 2011 and Talen Energy spinoff in 2015) to a pure-play US regulated utility focused on grid modernization and reliability improvement. The Rhode Island Energy acquisition (2022) added 770,000 electric and gas customers in a compact, densely populated state with above-average regulatory support for utility infrastructure investment.
