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.
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. Pumped Hydro Storage: In contrast, technologies like pumped hydro can store energy for up to 10 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. An energy storage system capable of serving long durations could be used for short durations, too.
Although the majority of recent electricity storage system installations have a duration at rated power of up to ∼4 h, several trends and potential applications are identified that require electricity storage with longer durations of 10 to ∼100 h.
