Storage can provide similar start-up power to larger power plants, if the storage system is suitably sited and there is a clear transmission path to the power plant from the storage system''s location. Storage system size range: 5–50 MW Target discharge duration range: 15 minutes to 1 hour Minimum cycles/year: 10–20.
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.
