Turbomachinery News Network: GE Vernova, Mitsubishi Power, NextDecade, and more

Welcome to the fourteenth edition of the Turbomachinery News Network. I’m James Cook, associate editor at Turbomachinery International.

The Electricity Supply Board of Ireland contracted GE Vernova to execute a life extension and modernization project at the Dublin Bay power plant, installing its GT26 high-efficiency upgrade and SEMIPOL, static excitation equipment, and startup frequency converter technology. The project intends to improve performance, reliability, output, and support Ireland’s energy transition goals. Completion is slated for 2026.

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 plant in Can Tho, South Vietnam. 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.

Rolls-Royce, Avio Aero, and IHI expanded their international partnership by signing a new collaboration agreement, allowing them to engage with the Edgewing joint venture for the Global Combat Air Program. Through these collaborations, the partners aim to accelerate the development of power and propulsion systems for next-generation fighter aircraft. Currently, they are progressing on the engine demonstrator, technologies for additive manufacturing, cooling systems, high-pressure compressor design, and more.

The Taiwan Power Co. also granted Mitsubishi Power and CTCI a $5.2 billion contract to execute a full turnkey project at its 2,800-MW Tung Hsiao power plant in Miaoli County, Taiwan. Mitsubishi Power will deliver five units with M501 JAC gas turbines, steam turbines, and auxiliary equipment, while CTCI performs engineering, procurement, and construction and balance-of-plant work for the project.

NextDecade completed the positive final investment decision and closed financial transactions for Train 4 and related infrastructure at Rio Grande LNG, with the company also progressing Train 5 toward FID in Q4 2025. NextDecade issued Bechtel Energy full notice to proceed with turnkey engineering, procurement, and construction on Train 4 and associated assets.
