Transco Pipe Expansions Give M-U Gas Producers Access to New Markets
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 
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.
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 
In April, Williams filed a formal application with the Federal Energy Regulatory Commission (FERC) to upgrade Transco pipeline’s capacity in Alabama and Georgia. The Alabama Georgia Connector Project involves upgrades to five compressor stations that will increase capacity in the region by an extra 63.8 million cubic feet per day (MMcf/d). The mighty Transco pipeline is a 10,200-mile natural gas transportation system that extends from south Texas to New York City. Transco is the nation’s largest-volume natural gas pipeline system, transporting about 15% of the natural gas consumed in the United States. Williams reversed the flow on Transco years ago to flow Marcellus/Utica gas to the south.
In March, environmental radical Pat McDonnell of PennFuture, the former Pennsylvania Secretary of the Dept. of Environmental Protection (DEP), along with his best friend THE Delaware Riverkeeper, Maya van Rossum, sued McDonnell’s former agency over permits the DEP issued to Williams to build the Regional Energy Access Expansion (REAE) project (see 
We have an update to a project we first told you about in June of last year called the Southside Reliability Enhancement Project (see 
A little over a month ago, MDN brought you the good news that the Federal Energy Regulatory Commission (FERC) has approved 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
