Tallgrass Adds Waste Heat Power Units at Gas Compressor Stations in Ohio, Indiana
Tallgrass has selected Turboden to install waste heat-to-power systems at three natural gas compressor stations in Ohio and Indiana, converting turbine exhaust heat into grid electricity.
(P&GJ) — Tallgrass has selected Turboden to deploy waste heat-to-power (WHP) systems at three natural gas compressor stations in Ohio and Indiana, converting turbine exhaust heat into electricity that will supply local power grids.
The systems will be installed at compressor stations in Columbus and Chandlersville, Ohio, and St. Paul, Indiana, using Turboden’s Organic Rankine Cycle (ORC) technology to capture excess thermal energy produced during pipeline compression.
Each facility is expected to generate about 10 MW of electricity, bringing the combined output from Tallgrass ORC installations to 46.1 MW of baseload power across four projects.
The projects build on a previously announced ORC system at a Tallgrass facility in Fayette County, Ohio, installed in 2024.
The technology works by capturing waste heat from gas turbine exhaust at compressor stations and converting it into electricity without requiring additional fuel or water use. The generated power will be supplied to local utilities in rural areas of Ohio and Indiana.
The systems will be supported by Turboanalytics, Turboden’s cloud-based monitoring platform, which provides predictive maintenance, anomaly detection and performance forecasting.
Tallgrass operates more than 7,000 miles of interstate natural gas pipelines, including the Rockies Express Pipeline (REX), Ruby Pipeline, Trailblazer Pipeline, Tallgrass Interstate Gas Transmission and Cheyenne Connector.
The company has also been expanding its power infrastructure footprint. Earlier this year, Tallgrass received approval for development of a 1.8-GW natural gas-powered data center campus, designed to support large-scale AI computing capacity.
Paolo Bertuzzi, President Turboden America LLC and CEO Turboden S.p.A., said the projects highlight growing interest in energy efficiency technologies at midstream facilities.
“We are proud that Tallgrass has placed its trust in our ORC waste heat-to-power technology. We hope that the Investment Tax Credit will remain in place for these projects, encouraging other oil and gas companies to follow Tallgrass’s example and helping this approach become a best practice for gas compressor stations. Improving energy efficiency and reducing CO₂ emissions in oil and gas processing and transportation are areas of strong interest for Turboden and the MHI Group. As power demand continues to rise across the United States, projects like these highlight the growing role of efficiency-driven, water-free baseload solutions in supporting energy security and long-term grid resilience.”
Waste heat-to-power projects can qualify as Waste Energy Recovery Properties (WERP) under the Inflation Reduction Act, making them eligible for federal investment tax credits that can cover up to 50% of project costs.
Turboden said the partnership reflects growing interest among midstream operators in capturing unused thermal energy from existing infrastructure to improve efficiency and support grid reliability.
