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.

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 
Williams is a powerhouse pipeline company. Williams operates more than 33,000 miles of pipelines in the U.S. and flows approximately one-third of the natural gas used in our country through those pipelines. Massive! The CEO of Williams, Alan Armstrong, is (or was) in Dubai for the United Nations COP28 climate meeting. He was there to preach the gospel of natural gas as the best way, the near-term way, to lower carbon dioxide emissions across the planet. He has proof to back up his claims. The U.S. is the only major country on earth to lower CO2 emissions since 2005. How? By switching from coal to natural gas for power generation.
Transcontinental Gas Pipe Line (Transco) is a natural gas pipeline that initially brought gas from the Gulf Coast of Texas, Louisiana, Mississippi, and Alabama, through Georgia, South Carolina, North Carolina, Virginia, Maryland, and Pennsylvania to deliver gas to the New Jersey and New York City area. It is owned and operated by Williams. With the advent of the shale revolution, Transco was converted to be bidirectional, flowing Marcellus/Utica gas south to as far as Texas. Transco now transports approximately 15% of the nation’s natural gas! It is a massive and vital pipeline. With the imminent start of the Mountain Valley Pipeline and an extra 2 Bcf/d flowing from the Marcellus to Transco’s Station 165 in Pittsylvania County, VA, how will Transco handle the extra volumes?
Some exciting news to share. Earlier this month, midstream giant Williams gave a green light to proceed with a new Transco pipeline expansion project called the Southeast Supply Enhancement. The project will flow an extra 1.4 Bcf/d (billion cubic feet per day) of Marcellus/Utica molecules southward along the Transco pipeline system, to deliver those molecules to states in the southern U.S. Mountain Valley Pipeline (MVP) will flow an extra 2 Bcf/d of M-U molecules to southern Virginia. Williams’ Southeast Supply Enhancement promises to flow some of those molecules further south (and southwest). This is a major new pipeline initiative that snuck up on us.
In August 2022, Columbia Gas Transmission (a subsidiary of TC Energy) filed an application 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 (see 
Pipeline giant Williams issued its third quarter update yesterday. Among the news of interest for the Marcellus/Utica was a statement by Williams CEO Alan Armstrong that the company completed the first half of Transco’s Regional Energy Access Expansion (REAE) project well ahead of schedule (on Oct. 21). The company is working with FERC to get the completed portion of the project online and flowing asap. REAE is a plan to beef up the Transco pipeline in Pennsylvania and New Jersey to deliver an extra 829 MMcf/d of Marcellus gas to PA, NJ, and Maryland. The initial portion (now complete) will flow about half that amount (see 
In 2015, Kelsy Warren and his Energy Transfer Equity (now just Energy Transfer) company pursued Williams, wanting to merge Williams into its operation. Williams initially fought ET tooth and nail, but in the end, caved and cut a deal (see 
According to analysts writing for S&P Global Commodity Insights, the long-range forecast from the U.S. National Weather Service calls for milder temperatures in the U.S. Mid-Atlantic region this winter. Warm temps equal less natural gas usage. Williams’ Transco Regional Energy Access Expansion (REAE) project will partially come online in October, flowing an initial 450 MMcf/d (out of 829 MMcf/d) of Marcellus gas to PA, NJ, and Maryland. More supply with less demand is a classic economic prescription for lower prices in New York, New Jersey, and the Mid-Atlantic region. So says the S&P analysts.
Williams CEO Alan Armstrong spoke at the Barclays CEO Energy-Power Conference in New York City yesterday. Certain members of the press were invited to attend (but sadly, not MDN). Armstrong had some interesting things to say at the Barclays soiree. Armstrong engaged in a little smack talk about the recently announced Enbridge deal to buy Dominion Energy’s remaining gas utility businesses for $14 billion (see 
The U.S. Dept. of Energy (DOE) is giving utility giant Duke Energy (mega profitable) and one of its natural gas suppliers, Williams (i.e., the Transco Pipeline, also mega profitable) $1 million of taxpayer money to do their jobs of monitoring for methane leaks. Dontcha love corporate welfare? Of course, if the government is going to blow taxpayers’ money on energy projects like uncompetitive and unreliable renewables, why not give a little love to fossil energy too, right? Still, it bugs us.
Two weeks ago MDN told you that eight “blue” states, including New Jersey (the Blue State Mafia), are challenging the Williams Regional Energy Access Expansion (REAE) project, a plan to beef up the Transco pipeline in Pennsylvania and New Jersey to deliver an extra 829 MMcf/d of Marcellus gas to PA, NJ, and Maryland (see
