Exide Technologies, provider of industrial and automotive battery solutions, has installed an energy storage system (ESS) in the heart of the Dutch city Den Haag.
The 500 kW/552 kWh storage with LFP batteries is installed in a pedestrian walkway close to the central train station.
Passers-by can look at the system, which is encased in glass. Signage has been installed to explain the purpose and the functions of an ESS.
The office building to be supplied by the new system, Rikskantoor, houses governmental agencies, commercial offices and restaurants. The ESS, called Stadsbatterij (City Battery), serves several applications, utilisation of PV energy, peak shaving for high energy consumers such as the elevators and the electric vehicle chargers. It supports the HVAC system.
The system is expected to lower total energy costs for the tenants and to reduce peak loads on the cable system of the urban power network.
The batteries flank a 500 kW modular and bi-directional converter. The constellation is designed to comply with the latest NEN4288 norm for ESS. Exide Customized Energy Systems (ECES) contributed to designing the new norm.
Dutch construction company BAM Group NV chose Exide among several potential partners for the project. Safety is a key issue as thousands of people pass by every day and the ESS is protected with an automatic aerosol fire-extinguishing system.
The project was an initiative of the energy company Energirijk den Haag and can be considered a template for other projects.
Michael Geiger, SVP Energy Solutions Division at Exide Technologies, said: “Energy storage systems are the cornerstone of modern cities’ progress. They help us capture renewable energy, ensuring cleaner and more reliable power. These systems redefine urban energy, making our cities greener and more resilient.”
