The results of five German and European studies are summarized in the appendix (table A2 ). The reported optimal storage energy capacities are large enough to supply 12–32 d of the average load within the considered region, which is about 2–3 times longer than what time series analyses found as the duration of low-wind events.
NFPA 855 also sets the maximum energy storage threshold for each energy storage technology. For example, for all types of energy storage systems such as lithium-ion batteries and flow batteries, the upper limit of storage energy is 600 kWh, and all lead-acid batteries have no upper limit. The requirements of NFPA 855 also vary depending on ...

the maximum rate of discharge that the BESS can achieve, starting from a fully charged state. • Energy capacity. is the maximum amount of stored energy (in kilowatt-hours [kWh] or megawatt-hours [MWh]) • Storage duration. is the amount of time storage can discharge at its power capacity before depleting its energy capacity. For example, a
In some scenarios, this storage size does not provide the maximum amount of energy to the system, as storage wastage is needed to maximize the energy provided. These scenarios usually have a high leakage rate of more than 40% per time interval, and small charge and discharge rates of less than 0.1C relative to the storage capacity.
Energy time-shift works by charging an energy storage system when electricity is cheap—typically during off-peak hours when demand is low and renewable energy sources like wind and solar are producing more energy than can be immediately consumed. Instead of curtailing this excess energy, it is stored in ESS.
