An energy storage system (ESS) for electricity generation uses electricity (or some other energy source, such as solar-thermal energy) to charge an energy storage system or device, which is discharged to supply (generate) electricity when needed at desired levels and quality. ESSs provide a variety of services to support electric power grids.
Electric Thermal Storage is a system that stores electric heat during the night when rates are lower, and releases the heat throughout the day. This doesn''t save energy overall, but it can save you money based on the difference in power rates between day and night. Check whether your area and electric utility offer time-of-use electricity rate ...
