Kaluza identified an opportunity for WPD to reduce local congestion in Lincolnshire through the optimisation of sonnenBatteries that store renewable energy from domestic solar panels. Working with energy supplier partners OVO Energy, 40 Kaluza-connected sonnenBatteries were installed for free into WPD customer homes, who already had existing solar PV.
Working closely with WPD’s Flexible Power team, Kaluza integrated with Flexible Power’s technology giving it access to their real-time telemetry. Kaluza is now aggregating these batteries to deliver local flexibility services to WPD by discharging unused energy to WPD’s network during times of high demand. In addition to batteries being charged up by solar panels, Kaluza is also optimising excess charging of the battery at times when grid electricity is cheapest and greenest. This local and flexible capacity is then intelligently used for offsetting customer peak demand and exporting electricity to the grid when called upon by WPD in a predetermined availability window.
The service is the first in the UK to trade domestic flexibility in a live DSO market and signals important progress in the journey to a decarbonised smart grid.
