Update on fast start Combine Cycle Gas Turbines (base load suitable for wind backup)

Latest from GE

FlexEfficiency* 50 Combined Cycle Power Plant

"GE's new FlexEfficiency* 50 Combined Cycle Power Plant is an innovative total plant design that defines a new standard for high efficiency and operational flexibility. The FlexEfficiency 50 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."
