NYMEX Gas Jumps 9.75% for Week on WV Pipeline Leak, Storage
The front-month October NYMEX natural gas futures contract settled Friday (Sept. 25) at $3.196 per MMBtu, up 28.4 cents, or 9.75%, for the week. That’s a nice week to be long gas. Most of the fireworks came on Thursday, when a leak on TC Energy’s Mountaineer XPress (MXP) pipeline in West Virginia knocked roughly 1.8 Bcf/d of Appalachian takeaway offline and sent futures up 9.06% in a single day, the biggest one-day gain since January (see WV Pipeline Leak Knocks 1.8 Bcf/d Offline, Gas Futures Jump 9.1%). Traders gave back 10.1 cents on Friday after Columbia Gas Transmission said it had found the leak and expected to fix it over the weekend. Even so, the contract ended the week at its highest Friday close since early July. Read More “NYMEX Gas Jumps 9.75% for Week on WV Pipeline Leak, Storage”
On Thursday morning, a natural gas leak at the Saunders Creek Regulator Station near Milton, WV (Cabell County) forced TC Energy’s Columbia Gas Transmission (TCO) to declare “force majeure” on the Mountaineer XPress (MXP) pipeline, one of the biggest Marcellus/Utica takeaway pipes in the region. Starting with today’s gas day (Friday, Sept. 25), the affected segment of MXP is cut to zero capacity until further notice. TCO estimates the hit to firm customers at 1.8 million dekatherms (MMDth) per day, which is roughly 1.8 billion cubic feet per day (Bcf/d) of Appalachian gas that suddenly needs somewhere else to go. Traders noticed. The October NYMEX futures contract settled up 27.4 cents (+9.06%) at $3.297 per MMBtu, the highest in about three months and the biggest one-day gain since January. 
Columbia Gas Transmission (a TC Energy company) has asked federal regulators for permission to permanently walk away from three underground natural gas storage fields straddling the Pennsylvania/West Virginia line near Majorsville — plugging 71 wells, tearing out a compressor station, and abandoning nearly 20 miles of pipe. On September 9, FERC set the clock on its environmental review. If you’re a landowner in Greene or Washington County, PA, or Marshall County, WV, this one lands in your backyard. Here’s the plain-English version of a very technical filing. 
A new report from RBN Energy fills in a piece of the Project Beacon puzzle we haven’t fully covered: two separate Millennium Pipeline expansions — one already sanctioned, one still on the drawing board — that DT Midstream and TC Energy are advancing to feed New England’s growing appetite for Marcellus/Utica gas. One is moving fast. The other needs New York State’s blessing, which is never a sure thing. 
TC Energy issued its second quarter 2026 update on July 30, and the headline numbers were strong: comparable EBITDA of C$2.9 billion, up 12% over 2Q25, and full-year guidance now tracking the upper end of the C$11.6–$11.8 billion range. Nice, but that’s investor stuff. The news that matters for Marcellus/Utica landowners, drillers, and midstreamers is sitting in the project tables — and in a demand forecast TC has now raised two years running. 
As MDN previously reported, TC Energy’s Virginia Reliability Project (VRP) in the Hampton Roads region (Virginia Beach, Norfolk, Newport News area) started construction in the second quarter of this year. It held a ceremony in September to commemorate the final weld (see 
Existing pipelines in the Marcellus/Utica region are testing the market for expansion. Two weeks ago, we told you that DT Midstream (50% owner of NEXUS Pipeline) is eyeing the growing AI data center market in northwestern Ohio as a customer for M-U molecules that flow through NEXUS (see 
It took eight years and untold legal fees (on both sides) before a tiny 3.4-mile, 8-inch natural gas pipeline under the Potomac River was finally built and went online in July (see 
We spotted a press release that fascinates us but will take some explaining. Yesterday, Hanwha Power Systems Co. (headquartered in South Korea) announced that it had signed a Memorandum of Understanding (MOU) with pipeline giant TC Energy to develop a sCO2 WHR (super-critical carbon dioxide waste heat recovery) project which will use the heat stream at a TC natural gas pipeline compressor station in West Virginia.
