The production of electricity with gas turbine and solar energy project aims to install at the Themis site (Targasonne, France) a prototype of hybrid solar/fossil gas-turbine system for electricity generation. The system features a 3800kWth pressurized air solar receiver combined with a fossil backup feeding a recuperated 1400kWe Turbomeca gas turbine with an external combustion chamber.
