6 FAQs about [Discharge duration requirements for energy storage power stations]
What is storage duration?
Storage duration is the amount of time storage can discharge at its power capacity before depleting its energy capacity. For example, a battery with 1 MW of power capacity and 4 MWh of usable energy capacity will have a storage duration of four hours.
What is the difference between rated power capacity and storage duration?
Rated power capacity is the total possible instantaneous discharge capability (in kilowatts [kW] or megawatts [MW]) of the BESS, or the maximum rate of discharge that the BESS can achieve, starting from a fully charged state. Storage duration is the amount of time storage can discharge at its power capacity before depleting its energy capacity.
Can a storage system be at full capacity for 8 hours?
If the grid has a very high load for eight hours and the storage only has a 6-hour duration, the storage system cannot be at full capacity for eight hours. So, its ELCC and its contribution will only be a fraction of its rated power capacity.
Should energy storage systems be recharged after a short duration?
An energy storage system capable of serving long durations could be used for short durations, too. Recharging after a short usage period could ultimately affect the number of full cycles before performance declines. Likewise, keeping a longer-duration system at a full charge may not make sense.
Do energy storage systems need long-term resiliency?
True resiliency will ultimately require long-term energy storage solutions. While short-duration energy storage (SDES) systems can discharge energy for up to 10 hours, long-duration energy storage (LDES) systems are capable of discharging energy for 10 hours or longer at their rated power output.
What is the ELCC of energy storage?
The ELCC of energy storage is higher than that of renewables since the stored power can be dispatched at any time but is limited by its duration. If the grid has a very high load for eight hours and the storage only has a 6-hour duration, the storage system cannot be at full capacity for eight hours.
