Abstract

See full text

An electric energy storage and recovery system is provided to store electric energy from a generator when it is not required for the electric power grid. The system employs a controller to switch a generator between operating as an electric motor in power storage mode and operating as a generator in a power generation mode. A weight engaged to a distal end of a cable may be wound upon a reel by the generator when operating as an electric motor. The weight, in an elevated position, will pull the cable from the reel to rotate the generator and produce electric power when operating in power generation mode.
