4 FAQs about Battery storage capacity

What is a battery energy storage system?

A battery energy storage system (BESS), battery storage power station, battery energy grid storage (BEGS) or battery grid storage is a type of energy storage technology that uses a group of batteries in the grid to store electrical energy.

What is battery energy storage capacity?

Battery energy storage capacity is the total amount of energy the battery can store, measured in kilowatt-hours (kWh) or megawatt-hours (MWh). Think of this as like the size of a water tank where you measure the water capacity in litres.

What is battery capacity?

Battery capacity is a core indicator of battery performance, representing the total amount of energy a battery can release under specific conditions, such as discharge rate, ambient temperature, and cutoff voltage. Battery capacity is usually expressed in three units: Ah (Ampere-hour), Wh (Watt-hour), and kWh (Kilowatt-hour):

What is battery storage duration?

Battery storage duration describes how long the battery can discharge at its rated power. It's calculated: Energy Capacity (MWh) ÷ Power Rating (MW). A 4 MWh battery with a 1 MW power rating has a 4-hour duration. A 1 MWh battery with a 2 MW power rating has a 0.5-hour duration. We've written about storage duration in more detail here.
