Northvolt & Mälarenergi partner to deploy battery energy storage for EV charging

Stockholm, Sweden – Northvolt and Swedish power provider Mälarenergi are partnering to establish a battery energy storage system at an electric vehicle charging station in Västerås, Sweden.

The Northvolt battery system is intended to reduce peaks in electricity demand of the charging station by more than 80%, and thereby lessen the impact of EV charging on the local electricity network.

The battery system will be commissioned in summer 2020 at the Rocklunda charging station and will be Mälarenergi’s first to be co-located alongside EV charging infrastructure.

Emad Zand, President Energy Solutions, Northvolt, comments: “Northvolt’s mission is to enable the future of energy by developing battery products across multiple industries. We believe that an electrified transportation system coupled with increased urbanization will rapidly increase the demands on utilities to strengthen their grids in a quick and flexible manner. The partnership with Mälarenergi represents our first commercial deployment, showcasing how batteries can be a part of the solution of the future grid.”

Helena Olssén Strategy Manager, Mälarenergi Elnät, comments: “We are excited to be partnering with Northvolt on this project which will support our vision for a sustainable energy system. In Mälardalen region we face challenges with both power consumption and grid capacity. For Mälarenergi, this project provides the opportunity to validate the benefits battery storage can provide for the electricity grid, the customer and society at large.”

“Rocklunda Fastigheter is proud to be able to contribute to increasing knowledge and experience regarding energy storage through our participation in this project. Local energy storage for the purpose of peak shaving is very interesting for us as commercial property owners as our arenas are energy and power intensive, especially during large events. The project fits in well with our ongoing work to deliver a more sustainable future,” said Björn Sandvall, Technical Manager, Rocklunda Fastigheter AB.

As technology provider, Northvolt will deliver a lithium-ion battery system based around its modular battery system, Voltrack, which will provide power output up to 220 kW and a usable energy capacity of 320 kWh.

The Rocklunda project is supported by financing from the Swedish Energy Agency (Energimyndigheten).
