Patent attributes
An energy storage system uses energy produced by a primary energy generation assembly beyond a peak primary use production limit to increase potential energy in a secondary energy generation assembly for later use to supplement energy produced by the primary energy generation assembly during periods of less than peak energy production by the primary energy generation assembly. The system includes a primary energy generation assembly having a peak primary use production limit and a peak total production limit. The peak total production limit is greater than the peak primary use production limit. A secondary energy generation assembly utilizes gravitational transfer of a weighting material from an elevated position to a lowered position to produce electrical energy. The secondary energy generation assembly is selectively actuatable such that energy generated by the secondary energy generation assembly supplements energy produced by the primary energy generation assembly.
