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.
