Enbridge Pennsylvania Pipeline Expansion

Statewide, multiple counties

Enbridge pledged in July 2025 to spend $1 billion expanding its natural gas pipelines into Pennsylvania, with projects to be named within 18 months, and the work tied to it so far is upgrades on its existing Texas Eastern system.

Enbridge's $1 billion Pennsylvania pipeline pledge is still short on specifics

The number that mattersEnbridge said at the July 2025 summit that its Pennsylvania projects would be announced within 6 to 18 months, a window that closes in January 2027.
Developer
Enbridge Inc. of Calgary, Alberta, through its Texas Eastern interstate pipeline, which runs from the Gulf Coast through Ohio and Pennsylvania to New Jersey and New York and has a peak capacity of 12.1 billion cubic feet a day, according to Enbridge.
Tenant
There's no tenant in the usual sense, since pipelines move gas for shippers. Enbridge says it's pursuing more than 50 data center opportunities across North America that could need up to 10 billion cubic feet a day of new gas capacity, but none of the releases we reviewed tie a Pennsylvania project to a named data center or power plant.
Current stage
Sen. McCormick's office said in July 2026 that the expansion is underway, citing the Appalachia to Market II project and the Armagh and Entriken HP Replacement Projects. Enbridge reports that Appalachia to Market II, about a $100 million project, went into service in 2025, and that its modernization of Texas Eastern compressor stations in Pennsylvania and New Jersey should be done in 2026. Enbridge's project pages also list the Appalachia to Market III Project, designed to add up to 32,000 dekatherms a day of gas supply in Pennsylvania and the broader region by replacing about 2 miles of pipe and modifying the Bedford Compressor Station; FERC issued its certificate February 25, 2026, and Enbridge expects construction to start in March 2027 with service by August 2027. None of Enbridge's 2025 or 2026 news releases we reviewed announce a new Pennsylvania route.
Decision body
The Federal Energy Regulatory Commission regulates construction and rates on interstate pipelines like Texas Eastern, and the federal Pipeline and Hazardous Materials Safety Administration sets safety rules. Enbridge notes that FERC temporarily raised the cost limits for smaller projects that can go ahead under its blanket certificate program.
Top issues
The main issues are how little has been disclosed about where the $1 billion will go, how added pipeline capacity feeds new gas plants for data centers, and what shippers pay. Enbridge's U.S. gas transmission earnings rose in 2026 partly because of a previously approved Texas Eastern rate increase.
Key opponents
No organized opposition group has been reported against Enbridge's Pennsylvania projects.
Key supporters
Sen. Dave McCormick, who listed Enbridge's pledge among the summit's commitments and highlighted its projects in his office's one-year update.

How we got here

July 15, 2025: Enbridge pledges $1 billion to expand its gas pipelines into Pennsylvania, with projects to be announced over the next 6 to 18 months. September 2, 2025: Enbridge announces two new gas transmission projects, on its Algonquin system in the Northeast and in Texas, neither in Pennsylvania. 2025: Appalachia to Market II enters service. February 13, 2026: Enbridge's annual report says Texas Eastern compressor modernization in Pennsylvania and New Jersey will be completed in 2026. July 11, 2026: Sen. McCormick's update lists Appalachia to Market II and the Armagh and Entriken HP Replacement Projects as underway. July 31, 2026: Enbridge's second-quarter report names no new Pennsylvania project.

What is at stake

Impacts raised and open questions

Air quality

Medium

Enbridge says its Texas Eastern Modernization program is upgrading compression facilities at multiple sites in Pennsylvania and New Jersey partly to reduce greenhouse gas emissions, with all phases expected to be completed in 2026. Compressor stations burn gas to push gas through the line, and Enbridge hasn't published site-by-site emissions changes.

U.S. Securities and Exchange Commission

Public safety

Low

The same Texas Eastern compressor modernization in Pennsylvania and New Jersey is meant to increase safety and reliability, according to Enbridge's annual report. Pipeline safety rules come from the federal Pipeline and Hazardous Materials Safety Administration.

U.S. Securities and Exchange Commission

Energy costs and the grid

Low

Enbridge reported higher U.S. gas transmission earnings in the second quarter of 2026, mainly from an East Tennessee rate case settlement and a previously approved Texas Eastern rate increase. Pipeline rates are paid by the shippers that move gas on the system.

Coverage of this project

Sources

Know your rights

In Pennsylvania, the local zoning ordinance sets the route. A conditional use is decided by the elected governing body (supervisors, commissioners or council). A special exception or variance, and an appeal of a zoning officer’s decision, go to the Zoning Hearing Board. Each is a public hearing on a record: affected neighbors can ask for party status, cross-examine witnesses, and appeal. Municipalities can also adopt data center ordinances with enforceable standards.

Take action

Organized community opposition is the single most effective check on these projects in Pennsylvania. Show up to hearings, submit comment when it is taken, support legal and expert-witness costs, and press your municipality for a real ordinance. Pennsylvania municipalities cannot simply freeze applications, but a curative amendment under the Planning Code gives them a defined window to fix a defective ordinance.
