Benefits
9EMax technology innovations
With the 9EMax turbine, you can reduce fuel costs by running up to 37% efficiency in simple cycle, and up to 54% in combined cycle. Annual fuel costs could shrink by as much as $5 million, while creating the potential for up to $6 million in additional revenue.
A game-changing package
A re-engineered turbine module with new casings, rotor, advanced exhaust diffuser, and four-stage hot gas path—the 9EMax is delivered as a fully assembled, modular solution. Its components are more accessible, including a reconfigured diffuser for efficient maintainability.

Sokolovska Uhelna
GE injected the latest technology into a full turbine upgrade for Sokolovska Uhelna in the Czech Republic. Evolving the 9E.03 to a 9E.04 (three-stage turbine to four-stage configuration) allows more energy to be extracted—but also modernizes the turbine for another 20 years of operation.

in simple-cycle baseload
“We’ll do a rotor life extension on that front-end section to give it 100,000 additional hours. We can do this because the compressor configuration of the 9E.03 and 9E.04 are identical.”
Robert Colwell
Senior Product Manager, Power Services, GE Power
Stadtwerke München
GE will upgrade two 9EMax gas turbines for German utility Stadtwerke München (SWM)—a power plant at the heart of Munich. The upgrade of these turbines and two A39 generators can increase plant output and boost operational flexibility per gas turbine.
