Hanwha Power has officially marked a major milestone in the US with the successful commissioning of the Trumbull Energy Center Combined Cycle Gas Turbine (CCGT) power plant in Ohio.
The opening ceremony took place on June 24, 2026, celebrating the start of commercial operations at the 950-megawatt facility. The project represents Hanwha Power’s first successful deployment of its Fuel Gas Compressors (FGC) in the US market.
The commissioning ceremony brought together several key partners involved in the project. Representatives from Korea Southern Power Co., Ltd. (KOSPO), Gemma Power Systems, Siemens Energy, Ohio state officials, the Korean Consul General, and project financing partners attended the event. Their participation reflected the strong international cooperation behind the project.
The Trumbull Energy Center was developed to help replace electricity generation lost after the retirement of older coal-fired power plants. Modern combined-cycle gas turbine plants produce electricity more efficiently than traditional gas-fired stations by combining a gas turbine and a steam turbine. This process generates more electricity while using less fuel.
The plant will supply electricity to the PJM Interconnection grid. PJM is the largest wholesale electricity market in the US and serves millions of homes and businesses across several eastern states. Reliable generation within this network is important for maintaining stable power supplies during periods of high demand.

Hanwha Power supplied three Fuel Gas Compressor units for the project. These compressors help deliver natural gas to the turbines at the correct pressure needed for efficient operation. Stable gas pressure is essential for maintaining continuous power generation.
The compressor units are equipped with Variable Frequency Drive, or VFD, technology. A VFD automatically adjusts the operating speed of electric motors to match changing conditions. This helps the compressors respond to seasonal pipeline pressure changes that are common across the PJM region and supports uninterrupted plant operation.
The project also marks an important business expansion for Hanwha Power beyond equipment manufacturing. The company secured a nine-year Long-Term Service Agreement covering maintenance support and major replacement parts. The agreement includes support through three major equipment overhaul cycles during the plant’s operation.
Hanwha Power Expands Services
Hanwha Power’s service center in Houston will manage much of this long-term support. The facility will provide on-site technical assistance, repair services, and refurbishment of key components. This approach gives the customer continuous support throughout the equipment’s operating life.
The long-term agreement also strengthens Hanwha Power’s service business in North America. Instead of focusing only on product sales, the company is expanding into lifecycle maintenance services. This strategy helps build long-term customer relationships while supporting reliable plant performance.
Joo Mong Choi, Chief Executive Officer of Trumbull Asset Management, said the successful commissioning demonstrates the reliability of Korean power generation technology in the US market.
He said the project will help supply stable electricity to the PJM grid while supporting the region’s transition toward cleaner energy. He added that the company looks forward to expanding its presence in North America through continued partnerships with leading Korean businesses.
Prakash Nair, Chief Commercial Officer of Hanwha Power, said winning both the equipment supply contract and the long-term service agreement reflects customer confidence in the company’s technical expertise.
He said the project provides a strong foundation for Hanwha Power’s long-term business in the US. He added that the company aims to build lasting service partnerships alongside future equipment projects.

Natural gas power plants continue to play an important role in many electricity systems. They provide flexible power generation that can quickly respond to changing electricity demand and support renewable energy sources such as wind and solar. Modern combined cycle technology also delivers higher fuel efficiency than older power plants.
Hanwha Power plans to continue expanding its business across major international markets, including North America. The company intends to supply more high-efficiency power generation equipment while growing its maintenance and service operations. It also plans to build on its experience in global power equipment to support future energy projects.
The successful launch of the Trumbull Energy Center strengthens Hanwha Power‘s position in one of the world’s largest electricity markets. It also demonstrates how long-term equipment support is as important as technology itself in today’s power industry.
