Denmark’s first urban energy storage system has been commissioned for Copenhagen.

ABB has announced a lithium-ion based battery energy storage system (BESS) will be integrated with the local electricity grid in the district of Nordhavn.

It is expected to play a key role in ensuring a reliable energy supply as the city increasingly focuses on sourcing its power from intermittent renewables such as wind and solar.

The flexible and modular system can help balance the grid through peak load shaving and frequency response.

The BESS, which has been commissioned for Radius, DONG Energy’s electrical grid division, forms part of the ‘EnergyLab Nordhavn’ project to develop and demonstrate future energy solutions.

These solutions are crucial for reaching the ambitious goal of turning Copenhagen into the world’s first carbon neutral capital by 2025.

Knud Pedersen, Chairman of the Board at Radius, said: “By integrating battery storage in Nordhavn we have the opportunity to learn more about how new technological solutions and market mechanisms interact with the grid.

“I expect that battery technology, on the longer horizon, holds the potential to reduce the load on the grid and make it run more cost efficiently.”

Copenhagen also plans to install 20,000 energy efficient LED streetlights.
