Electric Thermal Energy Storage (ETES) is an available technology solution using interim thermal energy storage in a packed bed of low-cost natural rocks. Electric air heating is used for charge and a heat recovery steam generator to either supply to a steam turbine for re-electrification or an industrial heat consumer at discharge.

Temperatures can be hottest during these times, and people who work daytime hours get home and begin using electricity to cool their homes, cook, and run appliances. Storage helps solar contribute to the electricity supply even when the sun isn''t shining. It can also help smooth out variations in how solar energy flows on the grid.
