GE Vernova Inc. (NYSE: GEV) announced that its HA gas turbine fleet has surpassed four million commercial operating hours worldwide, marking an important milestone for one of the power industry’s most advanced and efficient gas turbine technologies.
Since the first HA unit entered commercial operation in 2016, the fleet has grown to 128 units operating across 21 countries and has generated approximately 74 gigawatts (GW) of power plant capacity, the equivalent electricity needed to power more than 55 million U.S. homes.
GE Vernova’s HA gas turbine is today the world’s fastest-growing fleet in its class.
The milestone also highlights the growing performance of GE Vernova’s HA services, as each new turbine commissioned today is typically accompanied by a long-term maintenance and performance contract that grows GE Vernova’s high-margin services backlog for decades to come.
“Surpassing four million commercial operating hours is a strong validation of the HA fleet’s performance, reliability and relevance in today’s energy landscape,” said Eric Gray, CEO of GE Vernova’s Power Segment.
“This milestone reflects the confidence our customers have placed in GE Vernova’s HA technology and its established role in supporting flexible power generation around the world.
“As electricity demand rises and energy security is seen as national security, customers are increasingly focused on solutions that can deliver reliable, efficient, and more flexible power.
“Our HA fleet is helping meet that need today while continuing to evolve to support lower-emission power systems over time.”
GE Vernova’s HA gas turbines were developed in the context of a fundamental shift in the global power sector, involving the replacement of aging coal-fired generation with more efficient, lower-emission, and flexible power while enabling greater renewable energy integration.
That role is becoming increasingly important as electrification, industrial expansion, and rising demand from data centres and AI drive sustained pressure on power systems worldwide.
To meet that demand, GE Vernova is investing across its Gas Power manufacturing and services footprint (including facilities in Greenville and Schenectady) with nearly $300 million in planned investments in the Gas Power business.
This forms part of a broader $700 million investment across the company to meet unprecedented customer demand.
Recent project wins further illustrate the fleet’s global momentum.
In the U.S., Duke Energy secured 20 advanced HA gas turbines, several included in a framework agreement executed in 2025, while several other traditional utilities have entered significant multi-unit HA agreements.
A new customer archetype is also emerging: hyperscalers and data centre project developers now represent approximately 20 per cent of total gas turbine contracts.
In Türkiye, GE Vernova and Enka Power announced the start of commercial operation at ENKA’s 850-megawatt Kırklareli power plant (the first HA-powered plant in the country), bringing GE Vernova’s total installed gas power capacity in Türkiye to 13.5 GW.
In the UK, GE Vernova is supplying a 9HA.02 gas turbine for the NZT Power project, expected to be the world’s first commercial-scale gas-fired power station equipped with carbon capture technology.
Construction has started, and the gas turbine is expected to be shipped from GE Vernova’s manufacturing centre in Belfort, France, in June.
