The EPC contract signing ceremony for O Mon 4 thermal power plant project.
The O Mon 4 plant, a key element of Vietnam’s energy strategy, will utilize advanced combined cycle gas turbine (CCGT) technology and is designed to have a capacity of 1,155 MW. The facility is expected to commence operations by December 2028. Once completed, it will contribute to Petrovietnam’s total installed capacity, increasing it to over 93,000 MW, representing approximately 10% of Vietnam’s national power capacity.
The broader Block B – O Mon project includes offshore gas extraction at Block B, a gas pipeline, and a thermal power complex. O Mon 4 serves as a vital downstream component of this integrated initiative, which has faced nearly two decades of delays. In 2023, Vietnam’s Prime Minister assigned Petrovietnam the responsibility of managing both the O Mon 3 and O Mon 4 thermal power plants, ensuring coordination between upstream gas supply and downstream infrastructure development.
Vietnam’s updated national power plan outlines ambitious goals to expand power generation capacity by 2030, with a focus on renewable energy and the reintroduction of nuclear power. The plan, requiring an investment of $136.3 billion—over a quarter of Vietnam’s projected 2024 GDP—aims to reduce reliance on coal, which currently dominates the country’s energy mix. The O Mon 4 project aligns with these objectives, supporting Vietnam’s efforts to diversify its energy sources while maintaining a stable power supply.
