FERC Issues Final EIS for Boardwalk Pipe Carrying M-U Gas to SE
In April, we brought you the news that the Federal Energy Regulatory Commission (FERC) had issued a Draft Environmental Impact Statement (DEIS) for the Kosciusko Junction Pipeline Project (see FERC Issues DEIS for Boardwalk Pipe to Carry M-U Gas to Southeast). In June, we followed up with word that Boardwalk is dangling temporary capacity on the line during the gap between when the pipe can flow and when its anchor customer actually starts taking gas (see Boardwalk Offers Temporary Capacity Along Pipeline to Southeast). Now comes the next big milestone. Last Friday, FERC staff issued the final EIS (FEIS) for the $1 billion project. Kosciusko Junction — run by Gulf South Pipeline Company, LLC, a subsidiary of Boardwalk Pipelines — will lay 110.9 miles of new 36-inch pipe across nine Mississippi counties and take over 98 miles of existing pipe from sister company Texas Gas Transmission. It’s built to move 1.16 billion cubic feet per day (Bcf/d) of gas, expandable to 1.58 Bcf/d, from the Marcellus/Utica, Haynesville, and Fayetteville plays to power-hungry Southeast markets.

Texas Gas Transmission, LLC, a subsidiary of Boardwalk Pipelines, LP, wants to build the Dearborn County Lateral Project — roughly 12 miles of new 20-inch natural gas pipeline that begins at Texas Gas’s existing system in Dearborn County, Indiana, dips south across the Ohio River into Boone County, Kentucky, then hops back over the river into Hamilton County, Ohio. The destination is Vistra Corp.’s Miami Fort Power Plant, a coal-fired station slated for shutdown until someone had the good sense to convert it to natural gas instead. The lateral would move 265,000 dekatherms per day (Dth/d) of firm transportation service. A dekatherm is roughly one thousand cubic feet of gas, so call it about 265 MMcf/d (million cubic feet per day). Texas Gas filed with FERC in late May. Boone County leaders are not thrilled. 
In early April, the Federal Energy Regulatory Commission (FERC) issued a Draft Environmental Impact Statement (DEIS) for the Kosciusko Junction Pipeline Project in Mississippi (see 
Owensboro (KY) Municipal Utilities (OMU) is studying a proposed 545-megawatt natural gas power plant on roughly 30 acres at the former Elmer Smith Station site along the Ohio River, where coal generation ended in 2020. The developer, Green River East GenCo, holds an option to lease and has filed a grid interconnection application. OMU hired GDS Associates for a six-month study funded by the developer. OMU General Manager Tim Lyons stressed that the early-stage project isn’t guaranteed and that OMU won’t own the roughly $1 billion plant, citing customer risk. Instead, the plant may pursue power purchase agreements ahead of joining the MISO market in 2027. The plant will employ 15–20 workers. 
The Kosciusko Junction Pipeline Project, led by Gulf South Pipeline Company, LLC (a subsidiary of Boardwalk Pipelines), involves the construction of approximately 110 miles of 36-inch natural gas pipeline. The project has an estimated cost of $1 billion and is supported by a 20-year agreement with an anchor customer. It is designed to transport up to 1.16 billion cubic feet per day (Bcf/d) initially, with the potential to expand to 1.58 Bcf/d. The pipeline aims to connect gas supplies from key basins, including the Marcellus/Utica, Haynesville, and Fayetteville, to power markets in the Southeastern United States. In December 2024, Boardwalk pulled the trigger and made a final investment decision (FID) to move forward with the Kosciusko Junction project (see 
Gulf South Pipeline Company, a subsidiary of Boardwalk Pipelines, announced the launch of an open season for new natural gas storage capacity at its flagship Petal Gas Storage complex in Mississippi. In addition to the Petal open season, Boardwalk also highlighted significant expansion potential across two cornerstone assets: Choctaw Storage in Louisiana and the Midland Storage Complex in Kentucky. All three storage facilities are used to store Marcellus/Utica molecules. 
It’s always fun for us to discover a new pipeline project that has the potential to flow more Marcellus/Utica molecules to other markets—particularly the Southeast and Gulf Coast markets. Here is one such project that (until now) had escaped our notice. On Dec. 29, the Federal Energy Regulatory Commission (FERC) issued an Environmental Assessment (EA) for the Southeast Compression for Utility Reliability Expansion (SECURE) Project, a compressor-focused expansion project designed to enhance compression infrastructure across Mississippi and Louisiana for the Gulf South Pipeline Company. The project will expand the Gulf South Pipeline system to provide an extra 280,000 dekatherms per day (Dth/d) of firm natural gas transportation service (280 MMcf/d) to markets in the Southeast, including support for power generation customers. 
Regional and national indicators are driving optimism in the Marcellus/Utica Basin, which currently supplies 31% of U.S. natural gas. Despite recent constraints from low prices and limited pipeline capacity, drillers like Infinity Natural Resources and Expand Energy now predict significant output growth coming in the new year. This resurgence is fueled by surging in-basin demand from AI data centers, major power plant conversions in Pennsylvania, and improved takeaway prospects, such as Boardwalk’s proposed Borealis pipeline to the Gulf Coast (see 
We’ve pointed out (for years) the relative success the anti-drilling left has had in blocking new pipeline projects to carry Marcellus/Utica molecules to other regions, stifling new drilling in our area as a result. Although it has been and will continue to be a challenge to build new pipeline projects, the Trump administration is making it easier. Trump’s policies encourage new pipelines and more access to natural gas. We spotted an article from Reuters that provides an overview of eight pipeline projects that are actively being pursued to carry M-U molecules to other regions. We’ve covered all of these projects in previous posts. The Reuters article compiles the most likely candidates for new pipeline projects into a single, convenient article. 
Last week MDN brought you the great news that Boardwalk Pipeline Partners launched an open season to offer an extra 2 billion cubic feet per day (Bcf/d) of capacity along its 5,975-mile Texas Gas Transmission pipeline network that stretches from Ohio to Louisiana, running through Indiana, Illinois, Kentucky, Mississippi, and Arkansas along the way (see 
This is VERY exciting news! Boardwalk Pipeline Partners announced yesterday an open season to offer an extra 2 billion cubic feet per day (Bcf/d) of capacity along its 5,975-mile Texas Gas Transmission pipeline network that stretches from Ohio to Louisiana, running through Indiana, Illinois, Kentucky, Mississippi, and Arkansas along the way. According to the announcement, the expanded capacity’s express purpose is to connect Marcellus/Utica gas supplies with growing demand from electric utilities, LNG exporters, industrial users, and data centers in the Midwest and Gulf Coast.

We write about Boardwalk Pipeline Partners every now and again. They don’t have a lot of pipelines in the Marcellus/Utica region–but what they do have is important. One of the pipelines operated by Boardwalk is the huge Texas Gas Transmission (TGT)–originally built from the Louisiana Gulf Coast to the upper Midwest to supply Illinois, Indiana and Ohio with natural gas. But then the Marcellus/Utica Shale happened and TGT needed to change strategies. Through a series of projects, TGT made the pipeline system bidirectional, so it could flow gas from the Marcellus/Utica to points south, going as far as the Gulf Coast. In May 2016 TGT began to flow up to 626 million cubic feet per day of Marcellus/Utica gas as far away as the Gulf Coast (see
