Northern Powergrid has revealed its findings from its two-year Distributed Storage and Solar Study.
The study saw Northern Powergrid work alongside Moixa, managing a cluster of 40 of its Smart Home Batteries alongside 27 sets of rooftop solar, forming a virtual power plant in Barnsley. The trial looked to explore how smart home batteries can increase electricity network capacity, enable more homes to install solar panels and deliver financial benefits for customers.
Outlining the key findings, Northern Powergrid revealed energy storage systems could reduce the impact of domestic solar on the network by 20% and that the batteries, combined with rooftop solar, reduced the need for power from the network during the ore expensive and carbon-intensive evening peak by 25%. Trial participants with solar panels were also able to secure up to £60 off their electricity bills a year by storing free solar energy before then using it at night. When batteries were programmed to operate at certain times of the day, the impact was doubled.
Northern Powergrid added that there was still some network benefit when operating under threshold charging. Because of this, it said it indicates a government incentive to drive uptake of home batteries in areas of expected network constraints could stimulate uptake of energy storage, without there being an additional cost to DNOs.
Patrick Erwin, Policy and Markets Director at Northern Powergrid, said: “Following the findings of this trial, we would like to see the UK Government and energy regulators consider the role of storage in network management in more detail, potentially offering financial incentives to stimulate the market in areas where storage can deliver social as well as system benefits.”
