Maysville Project map (click for larger version)

Although TC Energy filed to build a new pipeline project in Kentucky last November, we’re just now learning about it. TC Energy is proposing the Maysville Project, a 42-mile pipeline expansion of its Columbia Gulf Transmission (CGT) System in Kentucky, to supply 340,000 dekatherms per day (328 MMcf/d) of Marcellus/Utica gas for East Kentucky Power Cooperative’s Hugh L. Spurlock Power Station in Maysville, KY. Traversing Rowan, Fleming, and Mason counties, this infrastructure project includes a new delivery meter station and interconnect in Maysville.

Columbia Gas Open Season for Extra 500 MMcf/d of M-U Capacity in OH
November 17, 2025November 17, 2025

Existing pipelines in the Marcellus/Utica region are testing the market for expansion. Two weeks ago, we told you that DT Midstream (50% owner of NEXUS Pipeline) is eyeing the growing AI data center market in northwestern Ohio as a customer for M-U molecules that flow through NEXUS (see DT Midstream Eyes Data Center/Power Market for NEXUS Pipeline). Now comes the news that TC Energy, the owner of the Columbia Gas Transmission (CGT) pipeline network, is conducting a non-binding open season to expand CGT capacity in Ohio, including in Columbus, Toledo, Lima, and other locations.

TC Energy Throws a Celebration for Pipeline Under the Potomac River
September 10, 2025September 10, 2025

It took eight years and untold legal fees (on both sides) before a tiny 3.4-mile, 8-inch natural gas pipeline under the Potomac River was finally built and went online in July (see Columbia Gas Pipeline Under the Potomac River Finally Goes Online). In April 2017, MDN brought you the news that Columbia Pipeline (owned by TransCanada, later renamed to TC Energy) had applied with the Federal Energy Regulatory Commission (FERC) to build a pipeline under the Potomac to connect natural gas from Pennsylvania to the Mountaineer Gas system in the Eastern Panhandle of West Virginia (see New 3.5 Mile Pipeline Project to Drill Under the Potomac River). That tiny section of pipeline is part of the larger Eastern Panhandle Expansion project—a project to deliver natural gas via local distribution channels (local utility Mountaineer Gas) to WV customers in several counties. Even though the project came online in July, TC and Mountaineer Gas held an official celebration ceremony yesterday. Read More “TC Energy Throws a Celebration for Pipeline Under the Potomac River”

TC Energy to Appeal $199M Pymt Related to Columbia Pipeline Lawsuit
May 16, 2024May 16, 2024

TransCanada Corporation, which renamed itself TC Energy in 2019, made a play for and bought out/merged with U.S.-based Columbia Pipeline Group in 2016 (see TransCanada and Columbia Pipeline Tie the Knot Today). TransCanada paid $13 billion for Columbia, including the assumption of $2.8 billion of debt. TransCanada paid Columbia shareholders $25.50 per share in cash. However, some Columbia shareholders were unhappy with the price and said the deal was all hush-hush until it was popped on everyone at the last minute. Nobody else had a chance to bid up the price, and the price did not reflect the company’s true value, according to the disgruntled shareholders. So they sued, and won (see Court: Columbia Pipe Shareholders Shafted in Sale, TC Energy Liable).

TC Energy Building New Regional HQ in Downtown Charleston, WV
February 6, 2024February 6, 2024

TC Energy, formerly TransCanada, is a huge pipeline company headquartered in Canada. TC owns and operates the Columbia Gas Transmission and Columbia Gulf Transmission pipeline systems in the Marcellus/Utica region. Yesterday, TC announced that it plans to move its regional headquarters from Kanawha City (a neighborhood in Charleston, WV) to downtown Charleston and build a new $60 million building in the process. TC said the existing 110,000-square-foot former CASCI building will be demolished and replaced with a new building, with construction expected to be complete in 2025 and employees moving in by 2026.

Columbia, Williams SE Va. Pipe Projects Now Fully Permitted to Build
January 2, 2024January 2, 2024

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 Columbia, Williams SE Va. Pipe Projects Get FERC Approval to Build).

Columbia, Williams SE Va. Pipe Projects Get FERC Approval to Build
November 20, 2023November 20, 2023

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 Columbia Files w/FERC to Replace 48 Miles of Pipe in Southeast Va.). VRP will add 100 MMcf/d of incremental capacity on Columbia’s system to service delivery points in southeast Virginia, namely for Virginia Natural Gas. The Columbia project works hand-in-glove with another project by a different company. Williams’ Transcontinental Gas Pipe Line (Transco) asked FERC if it could add new pipeline in an existing right-of-way and one new compressor station (see Transco Pipe Seeks to Build New Compressor Boosting Flows in Va.). The Commonwealth Energy Connector Project, as it is called, will build six miles of new pipeline within Transco’s existing right-of-way in Virginia, expand a meter station, and build a 30,500 hp electric motor-drive compressor. Both projects (considered together by FERC) were approved by FERC’s commissioners in an order issued last Thursday.

Maryland Loses Fight to Block Tiny Pipe Under Potomac River
October 13, 2023October 13, 2023

We finally have some good news to share concerning Columbia Gas’ project to build a tiny 3.37-mile, 8-inch pipeline under the Potomac River from Maryland to West Virginia. The project, called the Eastern Panhandle Expansion, has been blocked repeatedly by leftwing wackos in Maryland (see Fed Judge Upholds Maryland Decision to Block Pipe Under Potomac). Maryland used the same flawed legal argument that New Jersey used to block the PennEast Pipeline — that eminent domain can’t be used against land owned or controlled by a state. PennEast won its case against NJ in the U.S. Supreme Court in 2021 (see PennEast Pipeline Squeaks Out 5-4 Supreme Court Victory Over NJ). The U.S. Court of Appeals for the Fourth Circuit (4th Circuit) ruled on Wednesday, using the PennEast case as precedent, that Maryland could not claim immunity from eminent domain.

Lefties Say Columbia Virginia Reliability Pipe Project is Racist
September 13, 2023September 13, 2023

VRP will add 100 MMcf/d of incremental capacity on Columbia’s system to service delivery points in southeast Virginia, namely Virginia Natural Gas. In April of this year, the Federal Energy Regulatory Commission (FERC) issued a draft Environmental Impact State (dEIS) that finds the project won’t hurt Mom Nature (see Columbia Virginia Reliability Pipe Project Gets Favorable dEIS). Like mind-numbed robots, the radical left continues to spout nonsense that VRP is racist.

Columbia Pipe Explosion in Va. Reduces Flows to Cove Point LNG 50%
July 27, 2023July 27, 2023

click for larger version

Tuesday morning, a portion of the Columbia Gas Transmission pipeline in rural western Virginia exploded and caught fire (see Columbia Gas Pipeline Near Interstate 81 in Va. Explodes, Big Fire). Fortunately, the blast did not hurt nearby residents, nor were there any injuries among first responders who helped extinguish the fire. However, Columbia shut down flows in that region, including reducing flows to Columbia Gas’ Loudoun LNG interconnect to zero. That outage has affected gas heading to the Maryland coast and the Cove Point LNG export facility.
