GE Vernova Starts First HA-Class Power Plant in Vietnam with 9HA.02 Turbines

PetroVietnam Power Corp.’s (PV Power) Nhon Trach 3 & 4 power plant began commercial operation in Ong Keo Industrial Park, Vietnam, approximately 70 km southeast of Ho Chi Minh City. The 1.6-GW plant is powered by two GE Vernova 800-MW blocks, each including one:

• 50-Hz 9HA.02 gas turbine
• STF-D650 steam turbine
• W88 generator
• Once Through heat recovery steam generator (OT HRSG)

The OT HRSG enables advanced water-steam cycles to deliver higher combined-cycle efficiency; furthermore, GE Vernova’s integrated Mark VIe distributed control system will assist PV Power in improving asset visibility, reliability, and availability while cutting operational and maintenance costs. Nhon Trach 3 & 4 is the first HA-powered, LNG-firing plant in Vietnam. It was built by Samsung C&T and Lilama.

“Renewable energy is expected to grow significantly in Vietnam,” said Ramesh Singaram, President & CEO of GE Vernova's Gas Power, Asia Pacific. “At the same time, lower carbon and highly efficient gas power generation will support this growth while ensuring grid stability and reliability. This project is expected to bring electricity for large industrial areas in the southern region, including Ho Chi Minh City and Dong Nai province. We are proud to execute the first HA project in the country, aligning with its national energy goals for a more sustainable economic growth.”

This project accelerates Vietnam’s transition from coal to natural gas-based power generation, expediting renewable energy integration by improving grid reliability and stability. GE Vernova’s H-class technology offers a lower environmental impact, generating approximately 60% fewer carbon emissions than coal-fired plants of the same electrical output. The power plant will play a vital role in satisfying the increasing electricity demand in southern Vietnam.

“Vietnam’s energy transition requires solutions that balance capacity, efficiency, and sustainability, which is why we chose GE Vernova’s 9HA.02 gas turbines for Nhon Trach,” said PV Power’s representative. “GE Vernova’s 9HA.02 gas turbine is central to our commitment to modern energy standards. It enables the plant to achieve greater than 63% combined cycle efficiency. Additionally, the 9HA.02 meets the strictest emission regulations, offers versatile fuel-switching capabilities—operating on LNG now, supporting up to 50% hydrogen co-firing and 100% hydrogen use in the future—ensuring alignment with Vietnam’s net-zero goals for decades.”

GE Vernova’s equipment generates up to 30% of Vietnam’s electricity requirements, leveraging over 1,100 employees across 13 locations throughout the country. The company’s domestic repair and manufacturing capabilities include the Phu My repair facility and Dung Quat HRSG manufacturing plant, where GE Vernova built the pressure part modules.

Kozienice Station

In November 2025, Enea Group ordered two of GE Vernova’s 9HA.01 gas turbine combined-cycle blocks for the gradual replacement of coal-fired power at Kozienice station in Poland, assisting with the country’s energy transition toward natural gas. Each block includes a 9HA.01 gas turbine, an STF-D650 steam turbine, a W88 generator, integrated Mark VIe distributed control system, and a three-pressure level with reheat heat recovery steam generator.

The steam turbine and generator will be locally manufactured in Poland at GE Vernova’s factories in Elblag and Wroclaw, respectively. Also, the gas turbines will be manufactured at GE Vernova’s Manufacturing Excellence Center in Belfort, France. The natural gas-fired Kozienice plant, using GE Vernova’s H-class equipment, is expected to generate a lower emissions impact with up to 60% less emissions compared to fossil-powered plants of a similar size. Enea’s new plant will be built by Calik Enerji, a Turkish engineering, procurement, and construction company.
