The Pennsylvania Public Utility Commission has been serving the evolving needs of utilities and the public for more than 80 years. The roles and responsibilities of the PUC have continued to shift over the years as legislators amended the Public Utility Code, and as the utility marketplace and technology evolved.

Today, the PUC oversees nearly 7,000 entities that provide in-state electricity, natural gas, pipeline, motor carrier, rail, telecommunications and water and wastewater services.

1907: The Beginning of a Legacy of Promise

In 1907, the state General Assembly created the Pennsylvania State Railroad Commission as the Commonwealth’s first public utility regulatory agency and precursor to today's PUC. It held jurisdiction over railroad, streetcar and telegraph corporations.


The Railroad Commission was abolished and replaced in 1913 with the seven-member Pennsylvania Public Service Commission (PSC), which was given the authority to regulate all public utilities. Thus began the legacy of balancing the interests of public service companies and the welfare of the public.
