Global electricity demand climbs, and GE Vernova HA-class gas turbine units have surpassed 4 million operating hours

GE Vernova (NYSE: GEV) recently announced that its HA-class gas turbine units have surpassed 4 million hours of commercial operation worldwide. As one of the most advanced and efficient gas turbine technologies in the power industry, this breakthrough achieved by the HA-class gas turbines marks an important milestone for top-tier high-efficiency gas turbine technology in the power sector.  

Since the first HA-class gas turbine was put into commercial operation in 2016, the scale of this unit has continued to expand. Currently, it covers 128 standalone operations in 21 countries worldwide, with an installed capacity of approximately 74,000 megawatts, equivalent to meeting the electricity needs of over 55 million households. As of now, GE Vernova's HA-class gas turbine remains the fastest-growing gas turbine of its kind in the world.  

Furthermore, this milestone also underscores the continuous enhancement of the comprehensive strength of the supporting services for the GE Vernova HA series units. Each newly commissioned gas turbine is typically accompanied by a long-term operation and maintenance agreement as well as a performance guarantee, which will drive the growth of servce orders for GE Vernova in the coming decades.

Eric Gray, CEO of GE Vernova's power generation business, stated, "This breakthrough of surpassing 4 million hours of commercial operation fully demonstrates the excellent performance, reliable operation, and strong adaptability of the HA series units in the current energy landscape. Achieving this milestone reflects customers' trust in GE Vernova's HA-class gas turbine technology and further underscores the crucial role of this technology in supporting flexible power generation globally. With the continuous growth of electricity demand and energy security being elevated to the level of national security, customers are increasingly focusing on power solutions that offer reliability, efficiency, and greater flexibility. Our HA-class gas turbine units are committed to meeting the needs of various customers worldwide today, and through continuous technological evolution, we aim to facilitate the construction of a lower-carbon power system in the future."

In the US market, HA-class gas turbines have achieved record-breaking success. Taking Duke Energy as an example, the company has secured 20 advanced HA-class gas turbines, several of which were included in the framework agreement signed in 2025. In addition, several other traditional US utility companies have also signed important multi-unit HA-class gas turbine agreements. Besides traditional customers, data centers are giving rise to a new group of non-utility customers, including hyperscale cloud service providers and other project developers, who now account for approximately 20% of the total gas turbine contract volume.

In the Turkish market, GE Vernova and Enka Power jointly announced that Enka's Kırklareli Power Plant, located in Kırklareli, Turkey, with an installed capacity of 850 megawatts, has officially commenced commercial operations. This power plant is the first in Turkey to adopt HA-class gas turbine technology, bringing the total installed capacity of GE Vernova's gas-fired power generation in Turkey to 13.5 million kilowatts.

In the UK market, GE Vernova has also supplied a 9HA.02 gas turbine for the NZT Power project. This project is expected to become the world's first commercially operated gas power generation base equipped with carbon capture technology. Currently, the project has commenced construction, and the gas turbine is expected to be delivered from GE Vernova's manufacturing center in Belfort, France, in June this year.
