Umicore - Belgium


Reactive power and frequency response services from the first second-life battery energy storage system on an industrial site in Belgium.


Energy intensive user Umicore wanted a system that would provide reactive power to help improve power quality on their site, whilst also delivering a new revenue stream for the business. The firm has an ambition to develop, produce and recycle materials in a way that fulfils its mission: materials for a better life. Playing a broader role in improving the penetration of renewable energy was also appealing to Umicore and participating in a grid balancing solution enabled them to do this.

The E-STOR energy storage system will provide reactive power to the site and frequency response services to the grid. The batteries in the system have a combined energy storage capacity of 720 kWh and can deliver 1.2 MW in power.

The E-STOR has been connected to a DERMS (Distributed Energy Resources Management System) platform, alongside a load bank and generator. The platform, operated by aggregator Kiwi Power, will optimise the three assets in unison to capitalise on their differing performance characteristics and maximise value.

Together the assets will provide a frequency response service to Elia, the Belgium system operator.
