en.Wedoany.com Reported - A 950-megawatt combined-cycle gas turbine (CCGT) power plant in Ohio, USA, has officially entered commercial operation, providing electricity to the PJM Interconnection grid. The project, named the Trumbull Energy Center, commenced operations on June 24, with partners including Korea Southern Power Company (KOSPO), Gemma Power Systems, Siemens Energy, and Hanwha Power.
The gas-fired power plant was developed to help replace retired coal-fired power plants while providing reliable electricity to the PJM grid. PJM is the largest wholesale electricity market in the United States, covering multiple states and serving millions of customers. Hanwha Power achieved a milestone in this project by deploying its first fuel gas compressors (FGCs) in the U.S., supplying three compressor units for the plant's gas turbines.
The compressor equipment is specifically designed for the grid, utilizing variable frequency drive (VFD) technology to automatically adapt to seasonal pipeline pressure fluctuations in the PJM region. This system aims to maintain a stable fuel gas supply for the gas turbines, preventing plant operational disruptions. The combined-cycle plant enhances overall efficiency by pairing gas turbines with steam turbines, capturing waste heat from exhaust gases, achieving higher efficiency than traditional gas-fired plants. In addition to equipment supply, Hanwha Power signed a nine-year long-term service agreement covering maintenance support, spare parts supply, and three major overhaul cycles. The company stated that its Houston Service Center will provide on-site support and refurbish key components during the agreement period.
The project is set against a backdrop of rising demand for new gas-fired power generation in the U.S., driven by growing electricity needs from data centers, manufacturing facilities, and industrial users. Multiple utilities and developers have announced a series of new gas-fired power projects, boosting demand for key equipment such as turbines and compressors. Supply chain constraints have also prompted developers to sign long-term service agreements alongside equipment procurement to ensure reliable plant operation throughout its lifecycle.
Joo Mong Choi, CEO of Trumbull Asset Management, stated that the successful commissioning of the project and the deployment of Hanwha Power's advanced compressors represent a significant milestone, demonstrating the reliability of South Korean power generation technology in the U.S. market. He said the project will support the region's clean energy transition by providing stable electricity to the PJM grid while expanding partnerships in the North American power sector. Prakash Nair, Chief Commercial Officer of Hanwha Power, noted that securing the equipment supply contract and long-term service agreement reflects customer trust in the company's technology and operational capabilities. The company plans to expand its supply and service business for efficient power generation equipment in North America, leveraging experience gained from global power infrastructure projects.
