GE’s 7HA and 9HA Gas Turbine Efficiency

HAheroimageWeb

The World's Most Efficient Turbines

It's not often that a more powerful machine is also more efficient. But that's exactly what GE has accomplished with our new 7HA and 9HA gas turbines. They lead the industry in output, while using less gas-per-megawatt than any other turbine on the market. That's not only good for our customers. It's also good for theirs.

Put to the Test

GE’s test stand in Greenville, South Carolina, USA is one of a kind. Only here can a gas turbine, like GE's HArriet, be exposed to a variety of environments and challenges to validate her performance. 

Recently, Power Engineering visited HArriet at the test stand to see how she did.
