GE Vernova Inc. (NYSE: GEV) announced that its HA gas turbine fleet has surpassed 4 million commercial operating hours worldwide. The milestone represents operations across 128 units in 21 countries since the first unit began commercial operation in 2016.

The fleet has generated approximately 74 gigawatts of power plant capacity, equivalent to electricity for more than 55 million U.S. homes, according to the company. GE Vernova states its HA gas turbine is the fastest-growing fleet in its class globally.

"Surpassing 4 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.

The company reported continued demand for gas power technologies as customers seek deployable solutions for grid reliability. Recent contracts include Duke Energy securing 20 advanced HA gas turbines, with several included in a framework agreement executed in 2025. Data centers and hyperscalers represent approximately 20 percent of total gas turbine contracts.

GE Vernova announced nearly $300 million in planned investments for its Gas Power business, part of $700 million invested across the company. The investments target manufacturing and services capabilities in locations including Greenville and Schenectady.

Recent international developments include the start of commercial operation at ENKA's 850-megawatt Kırklareli power plant in Turkey, marking the first HA-powered plant in the country. In the UK, GE Vernova is supplying a 9HA.02 gas turbine for the NZT Power project, expected to be equipped with carbon capture technology.
