PGW began providing gas service to the City of Philadelphia on February 10, 1836, when the city's first 46 gas lights were turned on along Second Street, between Vine and South Streets. In 1841, PGW came under city ownership and in 1897 UGI Corporation (then United Gas Improvement Company) was contracted by the city to operate and manage PGW. Similar contracts were effective until December 1972 at which time the City contracted with nonprofit Philadelphia Facilities Management Corporation (PFMC) to operate and manage PGW. The seven-member board of directors of PFMC is appointed by the Mayor and its responsibilities, as set forth in a Management Agreement between the City and PFMC, make PFMC responsible for all operations of PGW through an executive management team including a chief executive officer, a chief operating officer, and a chief financial officer. By the 1940s, PGW was serving some 500,000 customers in Philadelphia, providing 99% of the gas distributed within the city limits. At this time, the gas provided was primarily carbureted water gas. In 1947, the City of Philadelphia stated that it valued PGW at more than US$100,000,000.
