What is battery storage? | National Grid
Battery storage, or battery energy storage systems (BESS), are devices that enable energy from renewables, like solar and wind, to be stored and then released when the power is needed most.
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.
Batteries are electrochemical devices and they store energy by converting electric power into chemical energy. This chemical energy is released again to produce power. There are a number of important battery energy storage systems, some well established, some new.
All battery energy storage systems must be approved by BC Hydro before installation to ensure safety and effective operation – even if your battery will not be sending power to our grid. It is important for BC Hydro's crews and other service providers to know if there is a battery onsite to ensure they can work safety.
Different types of Battery Energy Storage Systems (BESS) includes lithium-ion, lead-acid, flow, sodium-ion, zinc-air, nickel-cadmium and solid-state batteries. As the world shifts towards cleaner, renewable energy solutions, Battery Energy Storage Systems (BESS) are becoming an integral part of the energy landscape.
