GE has developed what it calls a “first-of-its-kind” power plant. 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 FlexEfficiency 50 Combined Cycle Power Plant is rated at 510 MW and offers fuel efficiency greater than 61%. The plant is the result of an investment of more than $500 million in research and development by the company.
