UK: Home storage enables renewables, savings during peaks


Battery storage could enable the use of up to 25% more renewable energy during periods of peak demand, according to a new report by UK network operator Northern Powergrid.

The finding, one of many made in a two-year study into the use of smart home batteries to boost electricity network capacity, is that more homes can to install solar and benefit from revised savings offers to customers.

During the study, Northern Powergrid worked with smart battery solutions company Moixa to manage a virtual power plant (VPP) project in Oxspring, Barnsley, made up of 40 of Moixa’s Smart Home Batteries connected to 27 sets of rooftop solar. The homes which participated in the study both reduced energy bills, as well as their carbon footprint, saving up to £60 ($75) on their annual energy bills.

The savings were made by using stored energy during the more expensive, more carbon-intensive evening peak periods, saving approximately 25% during the period, and at night when tariffs are typically higher than daytime rates.

Paris Hadjiodysseos, smart grid development engineer for Northern Powergrid, said: “We have to achieve net-zero carbon emissions by 2050 and real-world projects like this are paving the way for this to be achieved.

“This project has unveiled significant insights into a future flexible domestic electricity market, and demonstrated how smart energy storage systems can maximise benefits for both consumers and network operators.”
