GE Vernova Hits 2M Operating Hours with HA Gas Turbine Fleet

Published on: 

GE’s gas turbine fleet has compiled more than two million commercial operating hours across 88 units globally.

GE Vernova’s Gas Power division reported that its H-class gas turbine fleet has amassed more than two million commercial operating hours among 88 units installed across the globe. The HA fleet has a total installed power capacity of 47 GW, which is equivalent to the energy needed to power 35 million American homes. Grid operators can dispatch power quickly with flexible HA units, enabling the integration of renewable energy at scale.

The company reached one million commercial operating hours in 2021, as GE Vernova’s 9HA.02 gas turbines hit the market for first installation at the Sultan Ibrahim Power Plant in Malaysia. In 2022, GE Vernova released the next gas turbine platform with its 7HA.03 model—a 60-Hz design that enables gas-to-electricity conversions. HA combined-cycle plants encourage the transition from coal-to-gas power through the integration of renewables, system reliability, and grid stability.


“We’re thrilled to reach this latest milestone for our HA fleet, which is helping power plant operators reduce emissions, increase efficiency, retire coal-fired facilities, and integrate greater levels of renewable energy globally,” said Amit Kulkarni, Head of Product Management at GE Vernova’s Gas Power business. “We will continue to work with our customers and partners to introduce technologies for a lower-carbon future, including improved hydrogen-burning capabilities and carbon capture, storage and sequestration systems.”

GE Vernova’s pre-combustion and post-combustion capabilities include:

  • Pre-combustion: The H-class gas turbine collection can burn up to 50% by volume of hydrogen when combined with natural gas. Current 9HA.01/9HA.02/7HA.03 gas turbines contain the DLN2.6e combustion system, which may reach 100% hydrogen burn capability by 2030.
  • Post-combustion: H-class combined-cycle plants can be equipped with a carbon-capture system to minimize CO2 emissions by nearly 90%. Combined-cycle plant engineering recaptures and utilizes carbon from natural-gas processing.
