GE-Powered Combined Cycle Plant Sets New Efficiency Record
Guinness World Records recognized GE’s HA gas turbine for powering the world’s most efficient—up to 62.22%—combined cycle power plant.
The first unit equipped with an HA turbine officially began operation on June 17 at EDF’s plant located in Bouchain, France.
