Doosan Enerbility Wins Contract to Deliver Two Gas Turbines for U.S. Tech Company

Last week, Doosan Enerbility signed an agreement with a large-scale U.S. technology company to supply two 380-MW gas turbines by year-end 2026. This marks the company’s first overseas export of gas turbines, representing a significant milestone for the Korean power sector. Doosan Turbomachinery Services—the company’s Houston-based subsidiary—will handle gas turbine maintenance services.

“This contract signifies a turning point for South Korea, as this shows that our country is no longer dependent on imported gas turbines, but is now a country that has the capability to export its own homegrown gas turbines,” said Seungwoo Sohn, CEO of Doosan Enerbility’s Power Services Business Group. “We plan to show our appreciation to our customers by delivering on our commitments regarding product quality and deadline, while also working to expand our reach in the global market.”

In 2019, Doosan Enerbility partnered with the domestic, academia, and research sectors to successfully manufacture large-scale gas turbines for power generation. Next, the company performed over 15,000 hours of demonstration tests at the Gimpo Combined Heat & Power Plant, verifying the performance of domestically manufactured turbines. Doosan then secured multiple supplier agreements for eight total gas turbines.

The recent contract win was driven by a surge in AI data centers’ electricity demand: These facilities are struggling to obtain enough electricity on existing power grids, so developers have turned to gas turbines as a new energy source. Turbines offer quicker construction lead times, stable and reliable electricity supply, rapid start-up, and high operating efficiency. Doosan Enerbility aims to satisfy data center power demand with its own portfolio of locally developed gas turbine models.

Ansan Smart Hub

In late September 2025, under a signed memorandum of understanding (MoU) with GS Banwol Combined Heat and Power Co. (GS Banwol), Doosan Enerbility agreed to execute the Banwol Collective Energy Fuel Conversion and Modernization Project at the Ansan Smart Hub in Gyeonggi Province, South Korea. Per the MoU, the companies will jointly review methods for converting the aging combined heat-and-power (CHP) plant into a natural gas-fired CHP facility.

Doosan Enerbility will deliver the primary components, including locally manufactured gas turbines and additional equipment required for modernization, while also cooperating on the engineering, procurement, and construction process. The party in charge of plant operation, GS Banwol, will provide a stable supply of heat and electricity for the national grid and industrial complex.

The facility will be converted into a high-efficiency, eco-friendly power plant equipped with Doosan Enerbility’s H-class gas turbines—featuring a turbine inlet temperature in the range of 1500 ℃ or higher—accommodating a future fuel conversion to hydrogen. This aligns with the South Korean government’s policy to achieve an eco-friendly energy transition and carbon neutrality.

Component Manufacturing

In early May 2025, Doosan Enerbility and HD Hyundai Marine Engine signed a two-part memorandum of understanding to develop precision-casting manufacturing technologies for gas turbines and prototype blade materials, i.e., rotating airfoils connected to the rotor. According to the MoU:

• Doosan Enerbility will design and conduct quality assessments for each gas turbine blade
• HD Hyundai Marine Engine will develop and manufacture precision-casting materials
