Doosan Enerbility Modernizes, Converts Ansan Smart Hub to Natural Gas

Under a signed memorandum of understanding (MoU) with GS Banwol Combined Heat and Power Co. (GS Banwol), Doosan Enerbility will 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.

“In reflection of the industrial complex’s actual demand pattern, we plan to offer our high-efficiency, low-emission CHP solution starting from the initial stages, such as in the environmental impact assessment, basic design, and authorization stages,” said Hyeonho Lee, CEO of Doosan Enerbility’s Plant EPC Business Group. “By leveraging our two companies’ plant operation and EPC know-how, we plan to join forces in providing a stable energy supply and boosting regional industrial competitiveness.”

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.

GS Banwol and Doosan Enerbility will jointly engage in the technical review, feasibility study, and creation of a detailed implementation plan, maintaining a strategic and preferential partnership.

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

Doosan Enerbility, with this partnership, intends to strengthen South Korea’s domestic supply chain for gas turbine components and, as a result, will meet the increasingly high global demand for gas turbines. The contract to develop prototype blade materials aims to increase Korean suppliers’ gas turbine parts capacity, allowing global users to tackle the energy addition and gas turbine supply challenge.

Turbines in Poland

Also, the ORLEN Group awarded Doosan Škoda Power (Doosan) €125 million to supply two 55-MW back-pressure steam turbines, a two-pole generator, and conduct project execution for its heat-and-power plant in Plock, Poland. The project’s civil works phase will modernize two turbine sets, units TG4 and TG5, with full completion scheduled for 2029. Previously, Doosan completed the 70-MW Orlen Plock TG7 project in 2017.

Specifically, the order includes two single-casing extraction DST-S10 back-pressure steam turbines and a two-pole generator, with the first turboset component deliveries taking place in early 2025. Doosan will also supply transformers, bus ducts, and install two underground 30-kV high-voltage cable interconnections between the existing and new switch gear. Lastly, the company will execute foundation construction using micropiles.
