Doosan Enerbility Consortium Wins $618 Million Vietnam Power Plant Contract

A consortium led by South Korean plant builder Doosan Enerbility has won an 840 billion won contract to construct a gas-fired power plant in Vietnam, expanding the company’s order pipeline in a key Southeast Asian energy market. The contract is valued at about $618 million.

Doosan Enerbility formed the consortium with PetroVietnam Technical Service Corp., a Vietnamese energy services company known as PTSC. Under the engineering, procurement and construction contract, the partners will build the O Mon 3 gas-fired combined-cycle power plant for PTSC’s parent company, Petrovietnam. Completion is scheduled for 2030.

The project site is about 180 kilometers southwest of Ho Chi Minh City. The contract gives Doosan Enerbility another major role in the O Mon power complex, where the company has already secured work on a separate generating facility.

In June 2025, Doosan Enerbility won a 900 billion won contract as part of another consortium with a local company to build the O Mon 4 gas-fired combined-cycle power plant. That project, also commissioned by Petrovietnam, is scheduled for completion in 2028. The new O Mon 3 award therefore extends the Korean company’s involvement at the same site beyond the earlier contract.

Doosan Enerbility said it plans to pursue additional orders from Petrovietnam. The Vietnamese energy company intends to develop more gas-fired power plants in the country’s central and northern regions, in addition to the O Mon 3 and O Mon 4 projects.

The latest award also adds to a strong year of contract wins for Doosan Enerbility’s gas-fired power plant business. The company has secured five such projects so far this year, including the O Mon 3 contract, with a combined value of 3.87 trillion won.

For Doosan Enerbility, the Vietnam agreement strengthens its position as an engineering and construction supplier in overseas power infrastructure. It also deepens the company’s commercial relationship with Petrovietnam through two large projects at one location, while creating an opportunity to compete for the Vietnamese group’s planned developments elsewhere in the country.

The contract centers on project delivery rather than plant operation: the consortium is responsible for the engineering, equipment procurement and construction needed to bring O Mon 3 into service by the 2030 target.
