Cold weather on the Eastern Seaboard and in the Northeast in general drove throughput to a new record on its Transcontinental Gas Pipe Line (Transco), Williams Partners LP said.
Transco -- which claims the title of the nation's largest natural gas transmission system -- delivered a record-breaking 13.7 million Dth on Sunday (Jan. 8), surpassing the previous high of 13.5 million Dth 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 million Dth and eclipsing the previous three-day peak of 12.9 million Dth.
The Transco volume record was foreshadowed by natural gas market action the Friday before. "Weekend and Monday natural gas rocketed higher in trading Friday, led by Herculean advances at eastern market points," NGI reported. "Dollar-plus gains along the Eastern Seaboard were more than able to counter softer pricing in Texas, the Midcontinent and Midwest."
Contributing to the volume records were Transco expansions that were completed during 2015 and 2016, Williams Partners said. Virginia Southside (250,000 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) all entered service during the last 22 months, the company said.
Construction is under way on Transco's Garden State, Gulf Trace, Dalton, Hillabee (Phase 1) and Virginia Southside II expansion projects.
