FAQs 6

What is energy storage duration?

When we talk about energy storage duration, we’re referring to the time it takes to charge or discharge a unit at maximum power. Let’s break it down: Battery Energy Storage Systems (BESS): Lithium-ion BESS typically have a duration of 1–4 hours. This means they can provide energy services at their maximum power capacity for that timeframe.

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.

What is a discharge duration?

Different energy storage technologies offer different discharge duration ranges – a measurement indicating how many hours of energy can be delivered in one discharge cycle. The three main categories of durations are short, medium, and long, with each serving specific needs in the evolving clean energy space.

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.

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 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.
