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.
Technologies and economics of electric energy storages in power systems
Current power systems are still highly reliant on dispatchable fossil fuels to meet variable electrical demand.
