GE has developed the new FlexEfficiency* 50 Combined Cycle Power Plant, a product of ecomagination, to respond to the current and evolving energy production needs of the world. Developed from GE’s proven F-class legacy, this new single-shaft platform is an innovative total plant design that defines a new standard for high efficiency and operational flexibility.
A new level of flexibility and efficiency
Plant Overview
The latest evolution of the FlexEfficiency 50 Combined Cycle Power Plant uses an integrated approach to reduce fuel costs, create additional revenue sources, improve dispatch capability and reduce carbon emissions compared to prior technologies.
With new gas turbine, steam turbine, and generator components—along with digital control capabilities, power island integration, and a turnkey plant design—the new 510 MW block-size plant features an expected baseload efficiency of more than 61 percent.
