Martin Next Generation Solar Energy Center

The Martin Next Generation Solar Energy Center is the second largest solar facility in the world and the largest solar plant of any kind outside of California. The facility is the first hybrid facility in the world to connect a solar facility to an existing combined-cycle power plant, providing 75 megawatts of solar thermal capacity in an innovative way that directly displaces fossil fuel usage. The project consists of up to about 200,000 mirrors over about 500 acres at the existing FPL Martin Plant site.
