The Public Service Corporation (PSC) was an energy and transportation company in New Jersey. It was formed to shore up financing and development of New Jersey's streetcar and power companies at a time when they were growing but exhausting capital. It did this by leasing their operations or buying them outright, and using the size and integration of the systems to get favorable financing for improvements.
Its energy utility became the Public Service Electric and Gas Company. Its transportation business became the nucleus of New Jersey Transit's bus network, along with the Newark subway system.[1]
