U.S. Feedgas Demand Down After Incident at Columbia Gas Transmission

The natural-gas market disruptions hitting the Texas-Louisiana coast so far in 2020 — a pandemic, the collapse of the LNG export market, a rare hiccup in Permian gas production, and multiple hurricanes —threw a big wrench into market expectations. Everything had been moving along pretty smoothly since mid-2016, when the first of a series of new liquefaction trains came online at Sabine Pass LNG. As new LNG export capacity started up at Sabine Pass, Corpus Christi, Cameron, and Freeport, so did relatively steady, predictable growth in feedgas demand. Then came this crazy, unforgettable year. Still more liquefaction capacity started up, but LNG export volumes plummeted, mostly due to very weak export economics. Recently, LNG exports have been picking up and, whenever hurricanes stop pounding the Gulf Coast, the U.S. will likely finally experience the full impact of all 9.15 Bcf/d of export capacity operating at full strength, requiring nearly 10 Bcf/d of feedgas across the U.S, almost 9 Bcf/d of which is located in Texas and Louisiana. Gas flow patterns across Louisiana’s dense network of pipelines already are shifting in response to the incremental demand and are signaling increased supply competition along the Gulf Coast this winter. Today, we continue our series discussing the changing flow patterns along the U.S. Gulf Coast, this time providing an overview of the main drivers of those shifts to date, including LNG feedgas demand and Northeast inflows.

Total U.S. LNG export capacity is around 12 Bcf/d, including the still-commissioning-but-nearly-complete Calcasieu Pass. About 13.5 Bcf/d of U.S. natural gas supplies, or feedgas, is required to produce that much LNG, but feedgas demand has averaged just 10.5 Bcf/d over the past week despite still-soaring global gas prices and an undersupplied global LNG market. Two U.S. terminals are currently offline: Freeport LNG, which has been out of service since an explosion and fire in June, and now Cove Point LNG, which shut for annual maintenance October 1. Beyond those outages, which have taken about 2.75 Bcf/d of demand out of commission, LNG feedgas volumes have been extremely volatile, swinging as much as 2 Bcf/d within a week. Don’t expect this to last, however — with winter approaching, the return of both Freeport and Cove Point on the horizon, and the full startup of Calcasieu Pass in sight, feedgas demand will likely rise to new heights and soon consistently top 13 Bcf/d. In today’s RBN blog we take a closer look at the recent volatility in LNG feedgas and the potential demand coming this winter.

In a world where Marcellus/Utica natural gas supplies and Gulf Coast gas demand are increasingly interdependent, what would happen if flows along a critical route connecting the two regions were disrupted? The market caught a glimpse of that on January 21, when an explosion on Texas Eastern Transmission’s 30-inch line in Noble County, OH, shut down flows through its Berne compressor, which serves as a key gateway for Gulf Coast-bound gas out of Appalachia. Partial service was restored a few days later, but a chunk of the capacity remains offline as repairs are completed, and southbound volumes are running at 60% of what they were prior to the outage. Not too long ago, an outage severing Northeast producers’ access to a major takeaway route to the Gulf would have hammered Northeast supply prices, even during the peak winter demand months. But as expansion projects have vastly improved pipeline connectivity within Appalachia and takeaway capacity out of the region, they’ve transformed how some of those legacy long-haul pipelines function and even the role they play in the market. The TETCO outage provides a glimpse into what that will mean for the Northeast and its downstream markets. In today’s blog, we begin a series looking at the implications of a well-connected Marcellus/Utica, starting with a recap of the TETCO event and its immediate impacts on southbound flows.
