Vietnam’s state energy group Petrovietnam has signed an engineering, procurement and construction (EPC) contract for the O Mon 4 thermal power plant, advancing development of the flagship Block B-O Mon gas-to-power project.
The contract was awarded to a joint venture between South Korea’s Doosan Enerbility and Vietnam’s Power Engineering Consulting Joint Stock Company 2.
Situated in Can Tho in the Mekong Delta, O Mon 4 is considered a strategic project for strengthening Vietnam’s energy security and supporting its shift towards cleaner energy sources.
In 2023, the country’s prime minister tasked Petrovietnam to lead the O Mon 3 and O Mon 4 thermal power plants, enabling synchronised progress across downstream power generation and upstream gas supply infrastructure.
The broader Block B-O Mon project encompasses offshore gas extraction at Block B, a gas pipeline, and a thermal power complex, whereas O Mon 4 serves as a downstream component. Development has faced repeated delays for nearly two decades.
The O Mon 4 Thermal Power Plant will bring Petrovietnam’s total installed capacity to over 9,300MW, accounting for around 10% of the country’s total power capacity.
