Abstract
Hydroelectric pumped-storage includes monitoring electrical demand on a system over time. If the monitored demand exceeds a predetermined first value, fluid is allowed to flow substantially under the influence of gravity from a first aquifer to a second aquifer. Kinetic energy from the flowing fluid is converted into electrical energy. If the monitored demand drops below a predetermined second value, fluid from the second aquifer is moved to the first aquifer.
