“Intelligent energy platform” company Kaluza is claiming a UK first as it provides one of the country’s distribution network operators (DNOs) with flexibility from domestic batteries and transport solutions using one platform.

Electric vehicle (EV) smart charging and vehicle-to-grid (V2G) have been added into the flexibility service Kaluza’s provides to Western Power Distribution (WPD), with its platform already providing the DNO with flexibility using domestic battery storage systems from sonnen.

Kaluza lauded the milestone as the first time V2G has been used to provide flexibility to the local grid, as well as the first time a grid service has been provided using a mix of storage and transport devices.

Kaluza also hit a flexibility milestone with WPD in January as it utilised its sonnenBatteries in Lincolnshire to become the first residential flexibility platform to provide a paid service to a UK distribution network operator.

Its platform will now also shift EV charging away from times of high demand, while the combination of V2G and home batteries will be used to support WPD’s network with available export capacity during times of high demand.

Roger Hey, DSO systems and projects manager at WPD, said that the project “enables us to understand how all of these technologies will work together” whilst also bringing forward the “prospect of cleaner and cheaper energy” for consumers “in a way that can be replicated across the country”.

As part of the service Kaluza is providing to WPD, AI technology is utilised to provide a fully automated, machine-to-machine operation with no need for manual intervention.
