Williams Pre-Pre-Files for Southeast Supply Enhancement Project
Last November, MDN brought you the news that pipeline giant Williams had given the green light to proceed with a new Transco pipeline expansion project called the Southeast Supply Enhancement Project (see Transco Expansion to Add 1.4 Bcf/d Capacity to Flow M-U Gas South). The project was estimated to flow an extra 1.43 Bcf/d (billion cubic feet per day) of Marcellus/Utica molecules southward along the Transco pipeline system, delivering those molecules to states in the southern U.S. Since last November, Williams has upped the capacity to 1.587 Bcf/d (essentially from 1.4 to 1.6). Here’s the new news: On Feb. 1, Williams filed a request with the Federal Energy Regulatory Commission (FERC) to open a pre-filing review. In essence, Williams pre-pre-filed, giving us lots of new details about the project.

Here’s one instance when antis may have a legitimate point. In 2018, Equitrans Midstream, the builder of the 303-mile Mountain Valley Pipeline (MVP), proposed to extend MVP (when it’s done) by an extra 75 miles from the current terminus in Pittsylvania County, VA, to Alamance County, NC, to provide natural gas for heating and electric generation. The 75-mile extension is called MVP Southgate. Last year, Equitrans asked the Federal Energy Regulatory Commission (FERC) to extend Southgate’s project timeline an extra three years. FERC agreed in December (see 
The Algonquin Gas Transmission pipeline (owned by Enbridge) transports up to 3.09 Bcf/d through 1,131 miles of pipeline. 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, 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 
One week ago, the Interstate Natural Gas Association of America (INGAA) Foundation published a report called “Impact of Electrifying Natural Gas Transmission Compression” (full copy below). The Foundation commissioned global consulting and technology services provider ICF to assess and write a report on the potential impacts of electrifying natural gas transmission compression as one tool to address greenhouse gas (GHG) emissions along the natural gas supply chain. What did the researchers find?
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 
Spire Inc. is the owner and operator of the Spire STL Pipeline, a 65-mile pipeline that connects to and flows Marcellus/Utica gas from the Rockies Express (REX) pipeline in Scott County, IL, to residents and businesses in the St. Louis, MO area. Spire STL has been up and running since 2019 (see 
Shippers, including drillers, utility companies, and others that buy and sell natural gas, are now free to buy and sell producer-certified gas (PCG) or responsibly sourced gas (RSG) at all pooling points across the Tennessee Gas Pipeline (TGP) system following a decision by the U.S. Court of Appeals for the District of Columbia (DC Circuit). The judges of the DC Circuit dismissed a case brought by Antero Resources and EQT Corporation attempting to block TGP’s plan. We will explain.
Horizontal directional drilling (HDD) is a form of trenchless drilling to install pipelines, like natural gas pipelines, underground without digging a big trench first. It uses directional drilling, similar to drilling a horizontal shale well, in order to install the pipeline. In 2018, Energy Transfer’s Sunoco Logisitics unit, which was building the Mariner East 2 (ME2) pipeline project at the time using HDD, and the Pennsylvania Dept. of Environmental Protection (DEP) settled a lawsuit with radicalized green groups, including THE Delaware Riverkeeper, the Clean Air Council, and the Mountain Watershed Association (see 
Hyperion Midstream LLC, a subsidiary of Olympus Energy, is seeking a special exception to a Penn Township (Westmoreland County) zoning ordinance so it can build a six-generator compressor station along Wilderness Road over the next four years. Last night, Hyperion representatives and witnesses testified at a township zoning hearing in favor of the plan. Those who spoke said the proposed compressor site would not create a problem for the air and water quality of that area.
It’s hard to underestimate the influence and role of Pennsylvania on the world’s energy sector, especially over the past 19 years with the rise of the Marcellus Shale. However, advocates for fossil energy (like the American Petroleum Institute) are expressing concerns that PA’s dominant role may change to one with far less influence. Why? Lack of pipelines to transport PA’s production to other regions (or to export plants). Their concerns are valid (see 
The 303-mile Mountain Valley Pipeline (MVP), which runs from Wetzel County, WV, to Pittsylvania County, VA, is nearly done, thanks to our recent warm weather. What’s left to do? Less than one mile of “upland” pipe to install, less than 50 water/wetland crossings, and just one more compression station to finish. According to Equitrans, the majority partner and builder of MVP, the pipeline will come online in March. Finally!!!!
Big news broke yesterday about the Mountain Valley Pipeline (MVP) Southgate project. In 2018, Equitrans Midstream, the builder of the 303-mile MVP, proposed to extend the pipeline by an extra 75 miles from the current MVP terminus in Pittsylvania County, VA, to Alamance County, NC, to provide natural gas for heating and electric generation. The 75-mile extension is called MVP Southgate. Yesterday, various media outlets noticed and reported on a recent filing by Equitrans with the Securities and Exchange Commission. An Equitrans Form 8-K filing from Dec. 29 highlights a major change in the proposed MVP Southgate project.
Two related pipeline projects in southeast Virginia now have all regulatory approvals in hand, and the projects will soon begin construction. Columbia Gas Transmission (a subsidiary of TC Energy) applied with the Federal Energy Regulatory Commission (FERC) to build the Virginia Reliability Project (VRP), which includes two new compressor units and the replacement of existing pipeline. VRP will dig up, replace, and double the size of two sections, or about 48 miles, of the Columbia Gas pipeline between Chesapeake and Petersburg. Williams’ Commonwealth Energy Connector Project will feed VRP by building six miles of new pipeline within Transco’s existing right-of-way in Virginia, expanding a meter station, and building a 30,500-hp electric motor-drive compressor. Both projects received final approval by FERC in November (see
