GE’s 7HA.03 heavy-duty gas turbine is the world’s largest, most efficient, flexible 60 Hz gas turbine with the lowest cost conversion of gas to electricity today. Its >64% net combined cycle efficiency is higher than any other competing technology today, and its industry-leading flexibility allows full combined cycle plant load in less than 30 minutes, making it a great complement to intermittent renewable energy sources. This evolution of our 7HA.02 turbine is based on proven HA architecture, representing almost three decades of H-Class technology experience. HA power plants have supplied more than 18 GW of power around the world—the equivalent electricity needed to power more than 13.5 million US homes.


  • The 7HA.03 is the highest capacity 60 Hz gas turbine with 430 MW simple cycle output

  • The 7HA.03 provides cost benefits—over its lifecycle, total cost of ownership is 5% lower than F-Class turbines.

  • The 7HA.03 turbine uses advanced gas turbine materials, coating and cooling features to improve output, efficiency and flexibility.

  • GE’s DLN family (DLN 2/2.6/2.6+/2.6e) of combustion systems enables GE’s F- and H-Class gas turbines to reduce NOx emissions while enabling high plant efficiency plus extending outage intervals.
