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.
Uppsala
Vattenfall is constructing an unique battery storage facility in Uppsala, Sweden.
Pen y Cymoedd
A 22 MW battery is operational at one of Europe's largest onshore wind farms, Pen y Cymoedd.
Princess Alexia
At the Princess Alexia wind farm in the Netherlands, 88 BMW batteries have been connected to form a mega battery for storing electricity from wind energy.
Northvolt
Together with the Swedish battery manufacturer Northvolt, Vattenfall is developing a modular battery system as an alternative to diesel generators.
Boliden and Landskrona Energi
Vattenfall, Boliden and Landskrona Energi, with support from the Swedish Energy Agency, are conducting a research project and investing in a new battery storage facility in Landskrona.
Ray wind farm
A battery storage system with a capacity of 20 MW is planned at the Ray wind farm in the United Kingdom.
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.
