TC Energy Announces $1.5B Expansion to Columbia Gas for Powergen
Last Friday, TC Energy reported a robust first quarter in 2026, highlighted by a 14% increase in comparable EBITDA to $3.1 billion and record delivery volumes across its North American pipeline network. For the Marcellus and Utica shale region, the standout development is the newly announced $1.5 billion Appalachia Supply Project on the Columbia Gas system. Slated for 2030, this expansion will add 0.8 Bcf/d of takeaway capacity to meet surging electricity and data center demand. Appalachia is explicitly identified as a major contributor to the growth in U.S. natural gas production, and is expected to account for over 55% of the growth by 2035.

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. 
A little over a month ago, MDN told you about a new opportunity major midstream (pipeline) companies discussed in their latest quarterly updates: building natgas pipelines directly to data centers. Why? Because increasingly, those data centers are considering making their own power (see 
The 295-mile Portland Natural Gas Transmission System (PNGTS) spans New England from the Canadian border to pipeline connections in New Hampshire, Maine, and Massachusetts. The system began operations in 1999 and is located between three major pipeline networks originating in Canada and the U.S. TC Energy owns 61.7% of PNGTS. The remaining 38.3 percent is owned by Northern New England Investment Company. At least until yesterday, when PNGTS was spun off into its own standalone company, now owned by the evil BlackRock. 
What had been a regular stream of talk about providing power to data centers and artificial intelligence (AI) has become a torrent. There is a clear connection between data centers and the natural gas industry. This most recent round of quarterly financial updates by the biggest of the big pipeline companies (all of which have a huge presence in the Marcellus/Utica) reveals a new opportunity: building natgas pipelines directly to data centers. Why? Because increasingly those data centers are considering making their own power.
TransCanada Corporation, which renamed itself TC Energy in 2019, made a play for and bought out/merged with U.S.-based Columbia Pipeline Group in 2016 (see 
The 295-mile Portland Natural Gas Transmission System (PNGTS) spans New England from the Canadian border to pipeline connections in New Hampshire, Maine, and Massachusetts. The system began operations in 1999 and is located between three major pipeline networks originating in Canada and the Southern U.S. TC Energy owns 61.7% of PNGTS. The remaining 38.3 percent is owned by Northern New England Investment Company. The system includes 107 miles of facilities jointly owned by PNGTS and Maritimes & Northeast Pipeline. PNGTS owns 32% of those facilities. TC Energy announced today it is selling PMGTS to the evil BlackRock (run by CEO Larry Fink, a known anti-fossil fueler) for US$1.14 billion.
TC Energy, formerly TransCanada, is a huge pipeline company headquartered in Canada. TC owns and operates the Columbia Gas Transmission and Columbia Gulf Transmission pipeline systems in the Marcellus/Utica region. Yesterday, TC announced that it plans to move its regional headquarters from Kanawha City (a neighborhood in Charleston, WV) to downtown Charleston and build a new $60 million building in the process. TC said the existing 110,000-square-foot former CASCI building will be demolished and replaced with a new building, with construction expected to be complete in 2025 and employees moving in by 2026.
