Mitsubishi Power’s M701 JAC Turbines to Power Mekong Delta Region

In cooperation with Doosan Enerbility, Mitsubishi Power will deliver two M701 JAC gas turbines and auxiliary equipment for Petrovietnam’s 1,155-MW O Mon 4 gas turbine combined cycle (GTCC) plant in Can Tho, South Vietnam. The agreement was signed in August 2025 and, with the groundbreaking ceremony marking the start of construction, the plant is slated for completion in 2028.

These large-frame JAC gas turbines, the first to be deployed in Vietnam, feature more than 64% combined-cycle efficiency and reliability across 3 million operating hours. The engineering, procurement, and construction contract was awarded to both Doosan Enerbility and the Power Engineering Consulting Joint Stock Company 2.

“The O Mon 4 project marks a milestone in Vietnam's energy journey, and we are honored to contribute our JAC gas turbines to this key power plant,” said Akihiro Ondo, CEO and Managing Director of Mitsubishi Power Asia Pacific. “Building on our proven track record across Asia, we are committed to delivering reliability and performance for O Mon 4, working together with our partners.”

The O Mon 4 power plant, once operational, will generate stable electricity for the Mekong Delta region under the Block B – O Mon gas-to-power project: a national strategy to boost Vietnam’s energy security and advance the energy transition. It will increase Petrovietnam’s total installed capacity to over 9,300 MW, which is equivalent to approximately 10% of Vietnam’s domestic power system.

Also, this contract allows Mitsubishi Power to support Vietnam’s Power Development Plan, which outlines diversifying the energy mix, reducing coal dependency, and expanding natural gas and renewable energy. The project aids Vietnam in achieving its national target of net-zero emissions by 2050.

Decarbonization in Uzbekistan

In late May 2025, Mitsubishi Heavy Industries (MHI) signed a memorandum of understanding with the Ministry of Energy of Uzbekistan (MOE) to conduct a joint study on a power development plan to stabilize the country’s power sources and possibly upgrade its gas turbine fleet to be hydrogen-capable and other decarbonization efforts.

The program will continue for two years with financial support from the Ministry of Economy, Trade and Industry of Japan. Uzbekistan's government recently published its plan for introducing renewable energy by 2030, with the goal of reaching a renewable generation ratio of over 54%. MHI has supplied systems for thermal power generation installations in Uzbekistan that support stable power production in addition to its decarbonization technologies, including hydrogen co-firing and carbon capture, utilization, and storage.

Both parties have been working on:

• evaluating an upgrade for existing power plants leveraging MHI equipment;
• evaluating new gas turbine combined-cycle plants, including hydrogen co-firing and scope of necessary modifications; and
• capacity planning with the latest technologies.

Mitsubishi + EthosEnergy

Also in May, EthosEnergy’s Aerospace and Defense team was awarded approval from Mitsubishi Power Americas (MPA)/MHI to coat and heat treat newly manufactured turbine blades and vanes, including PT8, GG8, and GG4 turbines. This positions EthosEnergy to receive bid opportunities from any MPA-approved manufacturers.
