Williams Partners’ Transco Pipeline Delivers Record Volumes

Posted on

Williams Partners L.P. has delivered a record amount of natural gas on its Transco interstate gas pipeline to meet demand driven by recent cold weather conditions in Transco’s market area that includes the U.S. Eastern Seaboard.

The nation’s largest-volume natural gas transmission system, Transco delivered a record-breaking 13.7 million dekatherms (MMdt) on Jan. 8. The new peak-day mark surpasses the previous high of 13.5 MMdt that was set on Jan. 7, 2015.

The Transco system, which stretches from South Texas to New York City, also established a new three-day market area delivery record Jan. 7-9, averaging 13.6 MMdt (eclipsing the previous three-day peak of 12.9 MMdt).

Completed expansions to the Transco system in 2015 and 2016 contributed to the new volume records in early January. Virginia Southside (250,000 dekatherms per day or dth/d), Northeast Connector (100,000 dth/d), Mobile Bay South III (225,000 dth/d), Leidy Southeast (525,000 dth/d) and Rock Springs (192,000 dth/d) have all been placed in service in the last 22 months to serve customers’ demand for power generation, industries and local distribution.

Construction is already underway on the Garden State, Gulf Trace, Dalton, Hillabee (Phase 1) and Virginia Southside II expansion projects that will add even more capacity during 2017.
