2 Lawsuits in 6 Days: Big Green Targets the Permit Behind Every Pipe
Two federal lawsuits landed in the same Washington, D.C. courthouse six days apart last month, and while both are nominally about pipelines in Mississippi and Alabama, Marcellus and Utica readers should pay close attention. Not because of where the pipe goes — but because of which pipelines the greens dragged into their complaints as Exhibit A.

Add another name to the growing list of pipeline projects chasing Northeast Marcellus/Utica gas: Tennessee Gas Pipeline (TGP), a Kinder Morgan subsidiary, launched a non-binding open season on July 13 for its proposed 219 South Project. The idea is to grab gas from as far north as TGP’s Station 219 Pool in Pennsylvania (Zone 4) and move it south through Ohio, West Virginia, Kentucky, and Tennessee — up to 530,000 Dth/d (that’s dekatherms per day, roughly equivalent to 530 Mcf/d). TGP says demand along its “200 Line,” the backbone connecting Pennsylvania to Tennessee, is growing fast enough to justify testing shipper appetite now. If it goes forward, in-service is targeted for December 1, 2029. The open season runs through August 13. Below are the key details, straight from TGP’s posting. 
As part of Kinder Morgan’s second-quarter update, the company made an important announcement that (until now) it had not made. Namely, on May 26, 2026, TGP (Tennessee Gas Pipeline) placed in service its approximately $235 million Cumberland Pipeline project. The 30-inch pipeline is a 32-mile lateral originating from TGP’s existing 100 Line in Dickson County, Tennessee, and terminating at Tennessee Valley Authority’s (TVA) new natural gas-fired power plant in Stewart County, Tennessee. Big Green tried its best to block this project along with the gas-fired power plant, but failed. 
We’ve recently begun actively tracking flow restrictions on pipelines that carry Marcellus/Utica molecules. Current pipeline flow data for February 2026 show that the Marcellus/Utica (M-U) region is experiencing significant, albeit weather-driven, volatility. While the basin remains a production powerhouse, a combination of recent Arctic weather and localized maintenance has triggered several flow restrictions, including a restriction along the Tennessee Gas Pipeline. 
Last September, MDN told you that two major Kinder Morgan pipeline projects that will flow Marcellus/Utica molecules in the southeastern U.S. took a big step forward at the Federal Energy Regulatory Commission (FERC) with FERC actively working on an environmental impact statement (EIS) for both projects (see

Here’s a court case that slipped under our radar. Antero Resources Corporation challenged the Federal Energy Regulatory Commission’s (FERC) approval of a two-tier fuel rate structure imposed by Tennessee Gas Pipeline Company (TGP) following an expansion project. Antero had contracted with TGP to secure firm transportation capacity by funding the construction of new compressor stations, which are energy-intensive and require substantial fuel to operate. The tariff approved by FERC stipulated that Antero would always be charged the highest marginal fuel rate, as if its gas were the last and most expensive to transport through the pipeline. In contrast, other shippers paid an average fuel rate, leading to Antero paying two to three times the fuel rate of other shippers on the same pipeline segment. 
The Tennessee Valley Authority (TVA) is the sixth-largest power supplier and the largest public utility in the country. In 2021, MDN told you that TVA is spending over $1 billion to replace six coal-fired plants with natgas-fired turbines (see 
Here’s an important update for a project we haven’t discussed since last October. The Tennessee Valley Authority (TVA) is building a $2.1 billion state-of-the-art natural gas plant in Cumberland City, Tennessee (see 
The lawfare battle brought by radical green groups in New Jersey, including Food and Water Watch, the NJ Highlands Coalition, and the Sierra Club, aimed at overturning the decision to permit and build an electric compressor station and a pipeline that connects to it, is over. Done. Finished. Can we please stick a fork in it? We’re talking about the battle to block a compressor project in West Milford, NJ, part of Kinder Morgan’s Tennessee Gas Pipeline (TGP) East 300 expansion project, an upgrade of TGP to deliver an extra 115 MMcf/d of natural gas to Consolidated Edison and its customers in New York City and surrounding suburbs. The radicals just flamed out in a NJ appeals court and have no options left to challenge it. 
Ever so gradually, pipeline capacity to transport Marcellus/Utica molecules to other markets, particularly the Deep South, has been increasing. And it continues to grow, gradually. Two projects from Kinder Morgan aim to help that effort. The 2.1-Bcf/d Mississippi Crossing (MSX) and 1.3-Bcf/d South System Expansion 4 (SSE4) projects will move more Marcellus/Utica gas into Mississippi, Alabama, Georgia, and South Carolina. RBN Energy connects the dots. 
We have news of a brand new greenfield pipeline project (a rarity these days) that has the potential to flow Marcellus/Utica molecules to the Southeastern U.S. Yesterday, Kinder Morgan’s mighty Tennessee Gas Pipeline (TGP) subsidiary announced a final investment decision (FID) to build the Mississippi Crossing Project (MSX Project) after securing long-term, binding transportation agreements with customers for all the capacity. The $1.4 billion project involves the construction of nearly 206 miles of 42-inch and 36-inch pipeline and two new compressor stations aimed at flowing 1.5 Bcf/d of natural gas. MSX will compete with another recently announced project, the Kosciusko Junction Pipeline Project from Boardwalk (see
