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. Cycle life/lifetime is the amount of time or cycles a battery storage system can provide regular charging and discharging before failure or significant degradation.
A battery's average duration is the amount of time a battery can contribute electricity at its nameplate power capacity until it runs out. Batteries used for electricity load shifting have relatively long durations. We calculate a battery’s duration by using the ratio of energy capacity (measured in megawatthours [MWh]) to power capacity (in MW).
In 2018, the capacity was 869 MW from 125 plants, capable of storing a maximum of 1,236 MWh of generated electricity. By the end of 2020, the battery storage capacity reached 1,756 MW. At the end of 2021, the capacity grew to 4,588 MW.
As with capacity, there is no set definition regarding storage duration. According to US Energy Information Administration, storage duration depends on how grid scale batteries are used. It notes the following regarding capacity-weighted average storage duration in megawatt hours (MWh): Why is grid scale battery storage necessary?
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.
Power capacity refers to the greatest amount of energy a battery can discharge in a given moment. Batteries used for grid services have relatively short average durations. A battery’s average duration is the amount of time a battery can contribute electricity at its nameplate power capacity until it runs out.
