Battery storage systems

Battery storage systems support the integration of electricity from wind and solar power.

Vattenfall also offers batteries as fossil-free storage solutions. With battery storage, industrial customers can manage their consumption more flexibly by capping peak loads, with the so-called peak shaving. Peak shaving is a technique that lowers power consumption in times of maximum demand and thus reduces costs.

In areas with weak electricity supply, Vattenfall uses large batteries to increase capacity at peak times in order to avoid expensive grid expansion, or when waiting for transmission system operator (TSO) grid expansions, for example in the Swedish city of Uppsala.

Battery storage systems have the potential to play a key role in integrating renewable energy into the power grid. Vattenfall operates large battery storage systems in combination with wind and solar parks at several locations in Europe. These combined systems, also known as hybrid parks, balance the feed-in for greater stability of the power grid. Vattenfall’s newly built Haringvliet Energy Park in the Netherlands is the largest hybrid park in Europe.

Hybrid parks combine batteries, wind and solar power

With the Haringvliet hybrid energy park in the Netherlands, Vattenfall is combining the three technologies of battery, wind and solar for the first time.


Vattenfall is constructing an unique battery storage facility in Uppsala, Sweden.

Mobile batteries

Batteries are also suitable for mobile deployment. A mobile battery storage system from Vattenfall allowed snowmobiles and electric vehicles at the 2019 World Ski Championships to be charged with carbon-free power at all times.
