What is an energy storage system battery?
Like a common household battery, an energy storage system battery has a “duration” of time that it can sustain its power output at maximum use. The capacity of the battery is the total amount of energy it holds and can discharge.
Can energy storage be used for a long 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. So, its ELCC and its contribution will only be a fraction of its rated power capacity. An energy storage system capable of serving long durations could be used for short durations, too.
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.
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.
