A consortium of Doosan Enerbility and PTSC (PetroVietnam Technical Services Corporation) has reportedly won the contract to build the O Mon 3 gas combined-cycle power plant in Vietnam. Korean media reported the award on October 1, 2026, and the contract value is said to be about KRW 840 billion (roughly US$618 million). The owner is state-owned PetroVietnam (PVN), and completion is targeted for 2030. The contract signing date was not stated in the reports.
O Mon 3 will be built within the O Mon power complex, about 180 km southwest of Ho Chi Minh City. The project is being delivered on an EPC (Engineering, Procurement and Construction) basis, with Doosan Enerbility reported to handle EPC and PVN affiliate PTSC joining as a consortium partner. The share split within the consortium has not been confirmed.
According to the reports, Doosan Enerbility will directly supply the steam turbine, which would be the first application of a Doosan steam turbine in a gas combined-cycle plant in Vietnam. The gas turbine model has not been confirmed. Doosan is understood to have won the neighboring O Mon 4 project in June 2025 for about KRW 900 billion, with completion targeted for 2028, so the O Mon 3 award continues a run of orders in the same complex.
The plant capacity is reported at 1,155 MW (megawatts) by an energy trade outlet. The contract value is about KRW 840 billion (about US$618 million), with a target completion year of 2030. O Mon 4 in the same complex is valued at about KRW 900 billion with 2028 completion targeted. Doosan Enerbility said it has won five gas combined-cycle orders worth about KRW 3.87 trillion in 2026 so far, reportedly including orders in Saudi Arabia and Oman.
Vietnam is expanding gas-fired capacity to meet growing power demand, and the O Mon complex is regarded as a power supply hub for the Mekong Delta region.
The award shows that suppliers of major power equipment such as steam and gas turbines are widening their footprint in Southeast Asia by pairing equipment supply with EPC capability. Forming a consortium with a local partner affiliated with a state energy company helps with local procurement and permitting, and appears to be becoming a standard route for foreign firms entering the Vietnamese market. Consecutive awards within the same complex can also reuse design and construction experience and improve execution efficiency. However, stable natural gas supply and pricing remain the key variables for project viability, so follow-up LNG import plans merit attention.
First, which supplier is confirmed for the gas turbines. Second, whether the share split and work scope within the consortium are disclosed. Third, whether progress on O Mon 4, targeted for 2028, stays on schedule, which could affect the O Mon 3 timeline. Fourth, whether Vietnam’s LNG import terminal build-out and gas supply plans line up with the plant’s start-up.
