Batteries

With our battery parks, we help support and stabilize local power grids by delivering power when shortages occur in the electricity system, not least in greater Stockholm.

A battery park is like a giant power bank that is used when variations in electricity consumption or production become too great. The battery stores, located adjacent to a grid station, are charged when balance in the electrical grid allows and are discharged when need is high. Battery parks play a key role in the green transition of the energy system.

How a battery park works

  • The battery stores are located adjacent to a grid station, and are charged when balance in the electrical grid allows and discharged when need is high
  • Our battery storage facilities are comprised of containers with around 180 batteries per container. The batteries used are lithium batteries, just like most electric car batteries
  • The battery parks help support and stabilize local electricity grids by delivering power on a large scale when shortages occur in the electricity system, not least in the greater Stockholm area
