Williams Partners L.P. announced that its Transco natural gas pipeline has filed an application with the Federal Energy Regulatory Commission (FERC) to expand its existing Leidy Line in northern Pennsylvania and its mainline from New Jersey through Alabama by 525,000 dekatherms of natural gas per day to serve growing natural gas markets along the system. The project is fully subscribed by shippers with long-term contracts.

This application is made as another major expansion project on the Leidy Line nears completion. The Northeast Supply Link project expands Transco's existing system connecting the Marcellus Shale production region to the New York market by 250,000 dekatherms per day. Williams placed a portion of the project's capacity (125,000 dekatherms per day) into service in August 2013 and the remaining portion of the $390 million expansion is on schedule to be placed into service in November 2013.
