Doosan Enerbility Signs Deal with KOSPO to Supply 380-MW Gas Turbines

Doosan Enerbility signed a contract with Korea Southern Power Co. (KOSPO) to supply three 380-MW gas turbines for two combined-cycle power plants, with commercial operations targeted for December 2029. The contract signing ceremony was held at Doosan Enerbility’s headquarters in Changwon and was attended by company officials.

Under the agreement, Doosan will deliver two gas turbines to the 1,000-MW Hadong Combined Cycle Power Plant under construction in Hadong County, South Gyeongsang Province. A third turbine will be supplied to the 500-MW Goyang-Changneung Combined Cycle Power Plant in Goyang, Gyeonggi Province. Doosan will also provide generators and auxiliary equipment for both projects.

“KOSPO has signed procurement agreements for a total of four gas turbines to date, including this recent contract, thereby playing a crucial role in expanding the local manufacturing of gas turbines and cultivating a local ecosystem for gas turbines,” said Seungwoo Sohn, CEO of Doosan Enerbility’s Power Services Business Group. “Doosan aims to successfully execute this project by strictly adhering to the quality requirements and planned timeline, and we will continue to do our utmost to supply competitive gas turbines in the Korean domestic market.”

Doosan and KOSPO have collaborated since 2018 to promote the domestic gas turbine industry in South Korea. The companies have worked on developing hot gas path components for 7F-class gas turbines and advancing local development of core technologies. As a result, key components—including the 7F gas turbine, combustor, and rotor—have been manufactured locally.

The companies also completed commissioning of the Busan Bit Dream Power Plant, which subsequently entered commercial operation. Last year, Doosan and KOSPO delivered a joint presentation at a major gas turbine users conference in the United States to promote South Korea’s gas turbine technology to international customers.

Doosan said that, aside from four gas turbines contracted earlier as an alternative to coal-fired power plants before mass production of its gas turbine model began, it has secured or is pursuing supply agreements for all gas turbines needed at combined-cycle power plants in South Korea. The company plans to gradually expand its gas turbine production capacity to meet growing domestic demand.

Dukovany Nuclear Plant

Last week, Doosan Enerbility signed an approximately KRW 320 billion contract with its Czech subsidiary, Doosan Skoda Power, to supply a steam turbine and turbine control system for the Dukovany Nuclear Power Plant Units 5 and 6—a nuclear newbuild project underway in the Czech Republic. The contract scope includes supplying two machinery units consisting of the steam turbine-generator and control system.

This contract represents the first nuclear newbuild project to be executed by both Doosan Enerbility and Doosan Skoda Power, aiming to reach maximum synergy by combining extensive manufacturing experience with nuclear components-related expertise. If Doosan’s Team Korea wins additional contracts following execution, the company may collaborate with Doosan Skoda Power on Temelin Nuclear Power Plant Units 3 and 4.

The Czech government partnered with the Team Korea consortium in June 2025, signing a landmark contract with Korea Hydro & Nuclear Power for the Dukovany Units 5 and 6 project. Doosan Skoda Power holds expertise in power generation equipment, supplying 26 units of steam turbines for nuclear power plants in three countries: the Czech Republic, Slovakia, and Finland. In total, the company has supplied over 540 steam turbine units globally.
