Transco Throttles Southbound M-U Molecules to Work on SESE Project
Williams’ Transco Southeast Supply Enhancement Project (SESE) is a 55-mile, 42-inch-wide pipeline that will run through Pittsylvania County, Virginia, and Rockingham, Guilford, Forsyth, and Davidson counties in North Carolina. Construction for SESE started March 2, 2026, according to FERC filings. Transco (Williams) received its final federal authorization and a Notice to Proceed, and crews mobilized in early spring. Initial activities have included tree felling, installation of acoustic barriers, and test drilling in preparation for blasting. Antis finally gave up trying to block construction of SESE in June (see Antis Give Up Trying to Block Permit for Transco SESE Pipeline). Now comes word that Williams will “throttle back” southbound natural gas flows on the Transco system for most of the summer to accommodate work on SESE.

Williams’ Transco Southeast Supply Enhancement Project (SESE) is a 55-mile, 42-inch-wide pipeline that will run through Pittsylvania County, Virginia, and Rockingham, Guilford, Forsyth, and Davidson counties in North Carolina. It will provide natural gas to Duke Energy customers. Big Green sued to overturn a federal water quality permit issued by the U.S. Army Corps of Engineers. Big Green wanted the court to block construction until the full case could be heard. In May, a three-judge panel from the U.S. Court of Appeals for the Fourth Circuit (4th Circuit) rejected arguments Big Green put forward that claimed the Army Corps’ decision was “arbitrary and capricious” and refused to block construction (see 
It seems that not all of the judges who sit on the U.S. Court of Appeals for the Fourth Circuit (4th Circuit) are clowns, the way the three judges who oversee cases dealing with the Mountain Valley Pipeline (MVP) Southgate project are (see 
In April, MDN reported that anti-fossil fuel fanatics had not yet given up on trying to block construction of the Williams Northeast Supply Enhancement (NESE) pipeline, a $1 billion+ project designed to increase Transco pipeline capacity and flows of Marcellus gas heading into New York City and other northeastern markets. Even though there was an official groundbreaking ceremony at Brooklyn’s Floyd Bennett Field in New York City in April, antis are still doing their best to block this project. They pinned one of their last hopes on a relatively obscure state agency in New Jersey, pressuring it to refuse to issue a license for the project (see 
Earlier this year, the Federal Energy Regulatory Commission (FERC) approved the Williams Transco Southeast Supply Enhancement Project (see 
As we reported last week, anti-fossil fuel fanatics haven’t given up on trying to block construction of the Williams Northeast Supply Enhancement (NESE) pipeline, a $1 billion+ project designed to increase Transco pipeline capacity and flows of Marcellus gas heading into New York City and other northeastern markets (see 
We spotted an interesting article that posits Williams’ strategy is to expand its mighty Transco natural gas pipeline system by increasing the capacity of existing infrastructure rather than building new pipelines. The Transcontinental Gas Pipe Line (Transco) is the largest-volume, highest-capacity interstate natural gas transmission system in the U.S. It spans roughly 10,000 miles (with 60+ compressor stations) from the Gulf Coast (Texas/Louisiana) to New York City. The Williams strategy of expanding Transco rather than building new pipes minimizes disruption to communities and the environment while meeting growing demand from residential, commercial, industrial, and power generation sectors. 
Williams Companies is breaking ground tomorrow on the Northeast Supply Enhancement (NESE) pipeline in Brooklyn — the first new pipeline in New York in over a decade — signaling a broader national natural gas infrastructure boom. Driven by AI data center power demand, LNG export growth, and population expansion, the U.S. is tracking over 150 pipeline projects representing roughly 150 Bcf (billion cubic feet) of daily capacity. 
Anti-fossil fuel fanatics haven’t given up on trying to block construction of the Williams Northeast Supply Enhancement (NESE) pipeline, a $1 billion+ project designed to increase Transco pipeline capacity and flows of Marcellus gas heading into New York City and other northeastern markets. Last November, the states of New York and New Jersey issued federal Clean Water Act permits for their respective states, allowing NESE to be built (see 
Two pipeline kingpins are engaged in a deathmatch with the Federal Energy Regulatory Commission (FERC) to get their competing pipeline projects approved. One is Williams’ Transco Southeast Supply Enhancement Project (SESE), the other is EQT’s MVP Southgate project (see 
In November of last year, both New York and New Jersey issued the required federal water permits for the Williams Transco Northeast Supply Enhancement (NESE) natural gas pipeline project (see
