Battery storage

Our battery storage offer

Charging the future.

As renewable energy capacity expands, the ability to store energy is becoming increasingly important. By complementing our parks with battery storage capabilities, we can support the grid when needed and ensure a more consistent supply of electricity.

Advantages of Battery Storage

Battery storage allows us to respond quickly to changing needs. It provides the flexibility to adapt to variations in electricity production and demand, which is crucial in today's dynamic energy landscape. By storing energy when not all the electricity produced is needed, we can supply it to the auothoruty Svenska Kraftnät as an ancillary service when electricity production falls short. Conversely, when the grid requires less electricity, we can charge the battery as a service to the Svenska Kraftnät. By storing electricity when demand is low and selling it when demand is higher, we help support and ensure the balance of the power system.

A consistent supply to the grid


With battery storage, we achieve a smoother and more flexible delivery of renewable electricity all year round.

Stability in the power system


Electricity can be delivered as an ancillary service to the authority Svenska Kraftnät when electricity production falls short.

Local capacity resource


Batteries can be used to balance local grids, thereby enabling more connections.
