IMI has been awarded a contract to supply severe service valves (SSVs) for the new combined cycle power plant under construction in Homer City, Pennsylvania.
Once complete, it will be the nation’s largest natural gas-powered plant, and it will support a 3,200-acre campus designed to meet, amongst other things, the growing AI and high-performance computing needs of innovative technology companies.
The redevelopment of the former coal-fired Homer City site into the new Homer City Energy Campus marks a major milestone in the transition towards cleaner, more flexible energy generation. Once complete, the new 4.4 GW facility will be powered by seven state-of-the-art high-efficiency natural gas turbines.
The project represents a new generation of power infrastructure, designed specifically to support the recent growth in data processing and AI operations. IMI’s scope of supply covers all SSV packages across the plant, including key turbine bypass systems – critical components that ensure plant flexibility, reliability, and efficiency.
The order follows IMI’s long-standing collaboration with leading turbine manufacturers to standardise valve design and documentation for major combined cycle applications. This enables faster engineering, documentation, and delivery – vital factors for large-scale projects supplying power to data-intensive operations.
IMI is currently in the detailed design phase with Homer City Generation, with IMI’s first deliveries scheduled for September 2026. Since much of the critical infrastructure for the project is already in place from the legacy Homer City coal plant, the new Homer City Energy Campus is expected to begin producing power by 2027. Once operational, the new natural-gas powered plant is expected reduce greenhouse gas emissions by 60–65% per megawatt hour compared to the former Homer City coal plant.
