Details Emerge for Algonquin Pipeline Expansion in New England
In early September, MDN told you about the news that Enbridge had made a final investment decision (FID) for the Algonquin Reliable Affordable Resilient Enhancement (AGT Enhancement) project to flow an additional 75 million cubic feet per day (MMcf/d) of Marcellus/Utica molecules through the Algonquin Gas Transmission pipeline throughout New England and the northeast (see Enbridge Reaches FID on Algonquin Pipe Expansion in New England). At the time, there was precious little detail about the project. We now have the deets… Read More “Details Emerge for Algonquin Pipeline Expansion in New England”
An article appearing in the Peekskill (NY) Herald has this headline: “Natural Gas Pipelines: A Path to Renewable Energy?” The subhead reads, “Several projects propose solutions that address the threat of statewide energy shortages in the near future.” The article highlights four active pipeline projects in the Empire State that we have covered multiple times. These pipelines would flow more Marcellus gas from Pennsylvania (perhaps beyond) into New York and New England. They include Enbridge’s Project Maple, Williams’ Northeast Supply Enhancement (NESE), Williams’ Constitution Pipeline, and Iroquois Gas Transmission’s Iroquois Enhancement by Compression (ExC). Where does each project stand? 
The Tennessee Valley Authority (TVA) is a federally owned electric utility corporation in the U.S. TVA’s service area covers all of Tennessee, portions of Alabama, Mississippi, and Kentucky, and small areas of Georgia, North Carolina, and Virginia. TVA is the country’s sixth-largest power supplier and the largest public utility company. In May 2023, TVA announced that it would convert the Kingston Fossil Plant (coal-fired) in East Tennessee to become a natural gas-fired plant capable of generating 1,500 megawatts of electricity (see 
Speaking at the Sept. 30 Northeast Energy and Commerce Association 2025 Fuels Conference, gas pipeline executives expressed optimism that shifting federal and state politics in New England are creating opportunities for natural gas infrastructure expansion. Panelists emphasized the need to alleviate regional gas constraints to support the growth of electric generation and data centers. Speakers also highlighted the complementary role of LNG infrastructure, the challenge of financing new pipelines, and urged Massachusetts to reconsider strict decarbonization targets to ensure energy reliability. 
We’re not sure how to feel about this story. Outrage. Relief. Sarcasm. Befuddlement. All of those emotions swirl in our heads. For years, we have chronicled the radical/left position of former Attorney General (and now Governor) Maura Healey in Massachusetts with her opposition to pipelines and natural gas energy (here’s one of many examples: 
Coming out of left field, Enbridge (based in Canada, owner of significant Marcellus/Utica pipeline assets) announced yesterday that it had reached a final investment decision (FID) on two new pipeline projects, one of which will flow an additional 75 million cubic feet per day (MMcf/d) of Marcellus/Utica molecules through the Algonquin Gas Transmission pipeline throughout New England and the northeast. The project is called the Algonquin Reliable Affordable Resilient Enhancement (AGT Enhancement) project and is estimated to cost $300 million for “system upgrades within, or adjacent to, existing rights-of-way.” 
Shell, Norway’s Aker BP, and Canada’s Enbridge have all quit a Big Green-backed organization called the Science Based Targets initiative (SBTi), a corporate climate action organization that is supposed to enable companies and financial institutions worldwide to “play their part in combating the climate crisis,” primarily by eliminating fossil fuels. Someone finally woke up at Shell and these other companies, and they quit, pulling their funding with them, which shut down SBTi’s work on a so-called net-zero standard for oil and gas in the process. 
The Algonquin Gas Transmission pipeline (owned by Enbridge) transports up to 3.09 Bcf/d through a pipeline that is 1,131 miles long. Algonquin connects to Texas Eastern Transmission (TETCO), Millennium Pipeline, and Maritimes & Northeast Pipeline and supplies New England with critically needed natural gas supplies for power generation and consumer use. As we told you in September 2023, Enbridge conducted an open season to gauge interest in expanding Algonquin’s capacity to flow more gas into New England—mainly from the Marcellus/Utica—called Project Maple (see 
Compressor Station 165 in Pittsylvania County (in southern Virginia) is part of the Transco pipeline network, the nation’s largest-volume interstate natural gas pipeline system. CS 165 is also the endpoint of the Mountain Valley Pipeline, which carries 2 Bcf/d of natural gas from the Marcellus and Utica Shale from Wetzel County, WV, to Pittsylvania County, VA. Williams, the owner of Transco, replaced an aging fleet of engines at CS 165 with new turbines that decreased emissions and took up far less space. Enbridge, another major midstream company, is replacing hundreds of flow meters with newer models, which deliver much better information to the company in real-time.

Last week, MDN brought you the exciting news that THE largest gas-fired power plant in the country, along with a MASSIVE data center complex, will be built at a former coal-fired power plant site in Indiana County, PA (see 
The Texas Eastern Transmission Pipeline Company (aka TETCO) recently filed a request with the Federal Energy Regulatory Commission (FERC) to make a change in its plans related to upgrades at the pipeline’s Entriken Compressor Station located in Todd Township, Huntingdon County, Pennsylvania. Several years ago, TETCO (owned by Enbridge) filed to build the Appalachia to Market II Project (A2MII) and the Entriken HP Replacement Project (see
