Domestic demand side response (DSR) can reduce bills by 25%, the UK’s largest trial has found. The FLATLINE pilot project looked at the viability of a demand-side approach to energy management, using batteries in conjunction with smart energy management systems to allow demand to be ‘time-shifted’ to better align with generation. It found that the key enabling asset – the battery – led to cost savings of around £220 per year, or roughly a 25% reduction. Additionally, the average carbon emissions at the trial’s 20 newbuild homes at Parc Eirin in Wales were down by 71.2 tCO₂/year. This could be further reduced by 4-6% due to the DSR though. The homes were fitted with a 6kW Kensa Shoebox ground source heat pump, a 5kW sonnen 9.43 Hybrid battery storage system, a 3.6kW Viridian Clearline Fusion solar PV system and a hot water tank, as well as a resident facing interface developed by Sero and an energy management system developed by Passiv UK.
