Hanwha Power has supplied three fuel gas compressors to the Trumbull Energy Center in Ohio, marking the company’s first entry into the US combined-cycle power generation market. The 950 MW plant was developed to address the power gap from the retirement of aging coal-fired plants and will serve as a critical asset within the PJM (Pennsylvania-New Jersey-Maryland Interconnection) grid — the largest wholesale electricity market in the United States.
The power plant utilizes two Siemens Energy SGT6-8000H combined-cycle gas turbine, two heat recovery steam generators, and a single Siemens Energy steam turbine in a 2x2x1 configuration.
The fuel gas compressor sits between the incoming natural gas supply and the gas turbine fuel system. If pipeline pressure drops below what the turbine requires, the compressor boosts the gas pressure to maintain stable operation. The Hanwha Power fuel gas compressors units feature variable frequency drive technology specifically engineered to ensure uninterrupted operation by automatically adjusting to the extreme seasonal pipeline pressure fluctuations common in the PJM region.
Beyond the equipment supply, Hanwha Power has also secured a nine-year long-term service agreement, covering capital spare parts and maintenance services through three major overhaul cycles. Under the agreement, Hanwha Power’s Houston service center will serve as the primary hub for on-site support and component refurbishment, ensuring comprehensive lifecycle management for the units.
“The successful commissioning of the Trumbull Energy Center and the deployment of Hanwha Power’s advanced compressors represent a significant milestone, showcasing the world-class reliability of Korean power generation technology in the US market,” said Joo Mong Choi, CEO of Trumbull Asset Management. “As we contribute to the region’s clean energy transition by supplying stable power to the PJM grid, we look forward to further expanding our footprint in the North American power sector through continued, strong partnerships with leading Korean companies.”
The plant has the capacity to power approximately 900,000 homes. It is owned by Korea Southern Power Co. Ltd., Korea Overseas Infrastructure and Urban Development Corp., and Siemens Energy. Construction was led by Gemma Power Systems LLC, a Connecticut-based company that designs, builds, commissions, and operates large-scale power projects.
