Pennsylvania Power & Light Company was created in 1920 through the consolidation of eight electric companies with 62 power plants serving central and eastern Pennsylvania.
PPL has grown from a company with customers and facilities in one region of Pennsylvania to a diverse energy company with more than 10 million customers and nearly 13,000 employees in the United States and the United Kingdom.
Today, we are one of the largest purely regulated utilities in the U.S., one focused on advancing a smarter, cleaner, more reliable energy future for generations to come.
Pennsylvania Power & Light Company (PP&L) is Born
The company finishes construction of its iconic tower building in Allentown, Pa., where our headquarters still reside today. Wallace K. Harrison, architect of the tower building, used its design to inspire his design of Rockefeller Center in New York City.
PP&L powers the progress of the industrial revolution by building a vast energy grid of transmission, substation and distribution infrastructure. Over the next 17 years, a total of 750 industries are encouraged to locate in the region, creating more than 56,000 job opportunities for residents.

PP&L adds more than 150 megawatts of power generation capacity with the completion of Holtwood Unit 17 and Martins Creek power generation plants.
