A system and method for compensating for the changing power requirements of an electrical grid. A first generator is mechanically linked to a turbine and electrically linked to a power grid, such that the generator converts rotational energy into electrical energy to supply the power grid. The rotor of the generator is mechanically linked to the rotor of one or more additional generators, not connected to a turbine or the grid, via a continuously variable transmission. The turbine is maintained at optimal running speed. When the generator produces more electrical energy than required by the power grid, mechanical energy from the rotor is transmitted to the rotors of the additional generators. When the power grid requires more energy than generator produces, as the turbine runs at optimal efficiency, mechanical energy from the rotors of the additional generators is transmitted to the rotors of the first generator.
