Update: MXP Pipeline Fixed Early, Appalachian Gas Prices Bounce
On Friday, we told you a leak on Columbia Gas Transmission’s Mountaineer XPress (MXP) pipeline had pushed Appalachian gas down to $1.06 (see Mountaineer XPress Leak Sinks Appalachian Gas Price to $1.06). There’s an update, and most of it is good news. TCO fixed the leak and lifted its force majeure Friday afternoon, a day earlier than it had predicted. Local prices had already started to recover in Friday morning trading. But the second outage we flagged, on Texas Eastern in Kentucky, won’t be fixed until early November.

On Thursday, physical (spot) natural gas sold at Louisiana’s Henry Hub (the national benchmark) went for $3.30 per MMBtu. On the same day, gas sold at Texas Eastern M-2, which is the main price point for gas produced in southwestern Pennsylvania, West Virginia, and Ohio, went for $1.055. That’s the same molecule of methane, and our version fetched about 32 cents on the dollar. Why? Because a pipeline carrying Appalachian gas out of the region sprang a leak again. Here’s what happened, why it matters to your royalty check, and why there’s some good news on the horizon. 
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 
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
