Petrovietnam has begun construction of the VND27.7tn ($1.05bn) O Mon IV thermal power plant in Can Tho, Vietnam.

The 1.15GW facility is the first downstream project in the Block B–O Mon Gas-to-Power value chain.

The project is a critical path for the entire chain, with upstream gas development already two years ahead, as reported by The Investor.

The gas-to-power chain comprises offshore gas exploitation at Block B, the Block B-O Mon gas pipelines and a thermal power plant cluster.

Situated in the Malay-Tho Chu basin, Block B is Vietnam’s second-largest upstream gas project after Ca Voi Xanh (Blue Whale).

Commercial operations of O Mon IV will commence in December 2028, aligning with the first gas from Block B. Once completed, Petrovietnam will manage more than 9.3GW - 10% of the national grid's capacity.

The power plant will provide energy to the Mekong Delta.

A consortium of South Korea's Doosan Enerbility and Vietnam's Power Engineering Consulting Joint Stock Company 2 (PECC2) has been selected as the engineering, procurement and construction (EPC) contractor.

Lead contractor Doosan will handle design, technology, equipment supply and construction. The company aims to deploy advanced combined-cycle gas turbine technology to enhance efficiency and reduce emissions.

Doosan previously completed projects like the Vinh Tan 4 thermal power plant in central Vietnam.

Local partner PECC2 will provide consulting, design, EPC and on-site technical supervision.

PECC2 has worked on more than 100 power projects, substations and transmission lines. Its portfolio includes the Tri An hydropower plant expansion and the 500kV transmission line from Quang Trach to Pho Noi.

In January 2025, PECC2, Saigon Jim Brother’s Corporation and Solarvest (Vietnam) signed an MoU to accelerate renewable energy adoption in Vietnam.
