Siemens Powers Clean Energy Center

Scaled 60-Hz version of turbine designed for 275 MW of efficient output of electric power

Posted on November 26, 2012


The first of three Siemens' H-Class gas turbines has been successfully started at Florida Power & Light Company's (FPL) Cape Canaveral Next Generation Clean Energy Center in Port St. John, Florida, U.S.A., near NASA's Kennedy Space Center. Siemens said that this successful start was enabled by the Siemens full-power output testing program designed to put the turbine through many operating regimes.

        Three more units of the model SGT6-8000H gas turbine will also be installed at a similar new plant under construction in Riviera Beach, Florida. That project, FPL's Riviera Beach Next Generation Clean Energy Center, is scheduled to enter operation in 2014.

       The SGT6-8000H is the scaled 60-Hz version of Siemens' SGT5-8000H gas turbine, which was installed in a combined-cycle power plant configuration at Irsching Power Station in Bavaria, Germany, and achieved record efficiency of 60.75% in May 2011, said the company. The SGT6-8000H is designed for 274 MW output of electric power, and Siemens said it is likewise capable of reaching efficiencies topping 60% in combined-cycle operation, which FPL's Cape Canaveral and Riviera Beach plants will employ.

       FPL, a subsidiary of U.S.-based NextEra Energy, Inc., serves the third most customers of any American electric utility, with approximately 4.6 million accounts. When FPL's Cape Canaveral Clean Energy Center enters operation in 2013, it will use Siemens' gas turbines to generate power with 33% less fuel per MW/h than the site's previous plant. Because of this fuel efficiency, FPL expects that the new plant will more than pay for itself with fuel savings for customers estimated at more than US$1 billion over its 30-year operational life, the company said.
