| Gas power developments Vietnam’s first HA gas turbines
GE Vernova has announced the start of commercial operation of PetroVietnam Power (PV Power) Corporation’s Nhon Trach 3&4 power plant in Ong Keo Industrial Park in the Dai Phuoc commune, about 70 km southeast of Ho Chi Minh City, Vietnam. Employing two GE Vernova 9HA.02 gas turbines, the 1.6 GW Nhon Trach 3&4 plant, built by EPC companies Samsung C&T and Lilama, marks the first HA-powered plant in Vietnam, as well as the first to be powered by LNG. According to the Adjusted PDP8, an amendment to Vietnam’s National Power Development Plan VIII, LNG remains central to the flexible generation mix, with a generating capacity of more than 22 GW projected for 2030,

accounting for 9.5–12.3% of national installed capacity.
The Nhon Trach 3&4 project is another step in Vietnam’s transition from coal to gas and can
also expedite the integration of renewables by improving grid reliability and stability. 9HA.02 technology supports up to 50% hydrogen co-firing, paving the way for 100% hydrogen use in the future, “ensuring alignment with Vietnam’s net-zero goals for decades,” says PV Power. GE Vernova’s scope for this project, in addition to the two 9HA.02 gas turbines, includes two STF-D650 steam turbines, two W88 generators, and two once through HRSGs, the latter being key enablers of advanced water–steam cycles delivering higher combined cycle efficiency. The pressure part modules for Nhon Trach 3&4 were manufactured indigenously at Dung Quat HRSG manufacturing plant in Vietnam.
Rolls-Royce launches modular power plants
Rolls-Royce Power Systems (mtu) is launching what it describes as a new modular solution for gas fuelled piston engine based power plants that will provide security of supply and “accelerate the implementation of the German government’s power plant strategy.”
The new modular turnkey plants will be rated at between five and several hundred MW, depending on requirements, and are H2
-ready.
Thanks to use of preconfigured, factory-tested modules, 5, 10, 20 and 30 MW each, the power plants can be connected to the grid within 12 to 18 months of ordering, the company says. “With our modular gas engine power plants, we are implementing the German government’s power
plant strategy quickly and economically. Our partner network ensures speed and local value creation,” said Tobias Ostermaier, president, stationary power solutions, Rolls-Royce Power Systems. “True resilience comes from decentralisation, not centralisation. An energy system based on many distributed, modular generation units is less susceptible to large-scale disruptions and bottlenecks. Modular gas engine power plants offer exactly this structure,” said Michael Stipa, senior vice president strategy, business and product development stationary energy solutions at Rolls-Royce Power Systems. The German government’s much anticipated (and somewhat delayed) auctions
Milestone US project for Wärtsilä
through early-stage development, market entry, execution structuring, and ultimately long-term operation.

Wärtsilä is delivering the gas fuelled gensets for a new 123 MW power plant to be built in Odessa, Texas, which will supply power to the ERCOT grid. The largest Wärtsilä 31 installation to date, the power plant will be operated and maintained by Wärtsilä under a 10-year operation and maintenance agreement. The order was placed by the EPC contractor Saulsbury Industries on behalf of EMPower USA, an independent power producer. Wärtsilä has worked in close co-operation with EMPower, supporting the company
Through the operation and maintenance agreement, Wärtsilä’s role is strengthened as a long term operational partner, the company says, “supporting customers beyond technology delivery.” In the United States power market, where value is driven by availability, flexibility, and performance during periods of high demand, Wärtsilä says it is able to optimise plant performance and enhance project bankability for independent power producers. Wärtsilä sees the Odessa project as representing an important milestone in Wärtsilä’s expansion within the American independent power producer market. The plant’s ten Wärtsilä 31SG engines are scheduled for delivery in early 2027 and the plant is expected to be operational one year later. The 31SG engine is the most powerful of Wärtsilä’s medium-bore engines, with fast-starting capability allowing it to reach full output in 2.5 minutes.

for 12 GW of dispatchable back-up generating capacity to support renewables – including gas fired units that must be hydrogen ready – are currently expected to take place before the end of 2026.

A $33 billion, 9.2 GW natural-gas-fuelled power generation facility is planned for the former Portsmouth gaseous diffusion uranium enrichment plant site in Ohio, USA, alongside a 1 GW datacentre. The Japan–USA joint project, to be developed by SoftBank’s SB Energy and AEP, would be funded under Japan’s recent $550 billion investment commitment to the United States, part of a recent major USA–Japan trade deal.
