TC Energy Opens Ohio Pipeline Capacity Open Season Amid Rising Demand

TC Energy launched a non-binding open season to assess shipper interest in up to 500,000 Dth/d of new natural gas transportation capacity in Ohio, targeting rising demand from power generation, data centers and industrial growth.

COLUMBUS, Ohio (P&GJ) — TC Energy has launched a non-binding open season to gauge market interest in up to 500,000 dekatherms per day of new natural gas transportation capacity on its Columbia Gas Transmission (TCO) system as Ohio braces for a major surge in energy demand.

The open season runs from Nov. 12, 2025, through Jan. 9, 2026.

TC Energy said its existing TCO infrastructure is positioned to connect Marcellus and Utica shale supply to rapidly growing demand centers across the state, driven by new manufacturing, power generation projects and more than 40 data centers planned for the Columbus and New Albany regions.

“Ohio is poised for a major energy demand surge and TC Energy is in a leading position to serve this growth,” said David Brast, President, US Natural Gas Pipelines, TC Energy. “Natural gas is the foundation of reliable, affordable energy — and we stand ready to help power the next generation of Ohio’s economic growth.”

Demand Drivers

Ohio’s natural gas demand is forecast to rise by more than 30% over the next decade — about 1.2 billion cubic feet per day — one of the highest increases nationally outside LNG export states. Natural gas currently produces about 60% of the state’s electricity, well above the U.S. average of 43%.

TC Energy’s footprint in the region includes 5,000 miles of pipeline and more than $2 billion in investment since 2020, positioning the company to support what it calls a significant shift toward energy-intensive industries.

Open Season Details

• Capacity: Up to 500,000 Dth/d of incremental transportation
• Markets: Columbus, Dayton, Toledo and other growing industrial hubs
• Supply: Connections to shale gas production in Ohio, Pennsylvania and West Virginia
• Timing: Partial capacity could be in service by 2027, with full availability by 2029
• Anchor Shipper Terms: Long-term commitments of at least 200,000 Dth/d for 20 years

The open season is TC Energy’s first step in evaluating whether additional pipeline capacity will be built to meet Ohio’s projected long-term natural gas needs.
