GE and eSolar have an investment and licensing agreement that will incorporate eSolar technology into its offers of cost-effective ISCC and standalone solar thermal power plants. An ISCC project combines a combined-cycle system including a gas turbine, steam turbine, generators and a heat recovery steam generator, with a field of mirrors that focus sunlight on a tower to produce high temperature steam. Steam generated in the solar field is fed into the water-steam cycle of the combined-cycle plant, increasing the power of the steam turbine and creating extra megawatts of electricity without using any additional natural gas.

“GE has the world’s largest installed base of gas turbines that are being used in ISCC power plants, but these plants used higher cost and lower temperature trough technology and combined-cycle technology that have limitations in flexibility. Our revolutionary FlexEfficiency technology was designed from the ground up to integrate with renewable power, and the addition of eSolar’s high temperature tower technology to our FlexEfficiency combined cycle power plant is an important step forward for our industry because it allows us to offer an ISCC power plant that creates more value for customers at a competitive cost,” said Paul Browning, president and CEO – thermal products for GE Energy. “As a part of this transaction, GE is becoming an investor in the technology as well as the primary channel to the power industry though the license arrangement.”
