GE Launches "Breakthrough" Power Plant
GE today unveiled what it described as "a first of its kind" combined cycle power plant called the FlexEfficiency 50 rated at 510MW and with a fuel efficiency of more than 61%.
The company said the plant is the result of a US$500 million-plus investment in research and development as part of its stated bid to deliver "cleaner, more efficient energy."
GE said that by "rapidly ramping up and down" in response to fluctuations in wind and solar power, the technology will enable the integration of more renewable resources into the power grid. The company said its engineers avoided the "typical tradeoffs" between flexibility and efficiency by approaching the plant design from a total equipment and control systems perspective.
The new plant integrates "an evolution" of the company's 9FB gas turbine which operates at 50Hz - the widely used power frequency; a 109D-14 steam turbine running on the gas turbine's waste heat; GE's W28 generator, a Mark Vle integrated control system and a heat recovery steam generator, GE added.
