TC Energy’s Columbia Gas and Columbia Gulf natural gas transmission systems’ recent expansions out of the Northeast — the Mountaineer Xpress and Gulf Xpress projects, both completed in March — are responsible for a large portion of the uptick in Marcellus/Utica production in the last few months and they’ve added an incremental 860 MMcf/d of capacity for Appalachian gas supplies moving south to the Gulf Coast. The two projects join a number of other expansions in recent years that have inextricably tied Marcellus/Utica supply markets to attractive demand markets along the Texas and Louisiana coasts. Where is that latest surge of southbound supply ending up? Today, we look at the downstream impacts of the completed projects, namely on Louisiana gas flows and LNG feedgas deliveries.

U.S. Northeast natural gas producers in recent months got a substantial boost in pipeline capacity to receive and move incremental gas production volumes to attractive Gulf Coast markets. TC Energy’s Columbia Gas and Columbia Gulf transmission systems in March completed the Mountaineer Xpress and Gulf Xpress pipeline expansions, respectively, increasing the combined system’s Marcellus/Utica receipt capacity by 2.7 Bcf/d in the producing region, while also bumping up the Marcellus/Utica’s takeaway capacity to the Gulf Coast by nearly 900 MMcf/d. The duo of expansions is among the biggest takeaway capacity additions to be completed out of the Northeast, volume-wise, and among the handful that inextricably connect Marcellus/Utica supply markets to well-sought-after LNG exports markets along the Texas and Louisiana coasts. One of the export terminals these projects are designed to serve is Sempra’s Cameron LNG, where Train 1 began commercial operations in recent weeks. Today, we provide an update on the upstream and downstream implications of the recently installed Northeast-to-Gulf Coast pipeline capacity.

Of all the demand markets in the U.S., the biggest prize eyed by Marcellus/Utica natural gas producers is the Gulf Coast region, where a combination of industrial demand, LNG exports and power generation projects is driving a need for more and more gas. And beyond the U.S. Gulf Coast states, there lies still another market capable of gobbling up even more of the excess Northeast gas supply: Mexico’s rapidly growing gas-fired generation sector ––that is, assuming pipelines in Texas can get it all the way there. There is over 4.0 Bcf/d of Marcellus/Utica-to-Gulf-Coast takeaway capacity planned to be completed over the next few years. Today, we look at the status and timing of Northeast pipeline takeaway projects targeting the Gulf Coast.
