Milestone reached for UK’s largest domestic DSR trial

The UK’s largest domestic demand-side response (DSR) trial has achieved a key milestone with the first residents moving into pilot homes.

On 25 August, Sero confirmed that residents had moved into three pilot homes at The Mill site in Cardiff as part of the FLATLINE (Fixed Level Affordable Tariffs Led by Intelligently Networked Energy) project. The project, coordinated by Sero and backed by BEIS, is aiming to significantly reduce energy bills for residents, using a combination of DSR and demand shifting for both heat and electricity.

Another 46 homes are being developed at Parc Eirin in Tonyrefail with the first residents set to move in this autumn. This will take the total number of homes involved to 225.

Sero will provide its intelligent home comfort service to residents, working with PassivSystems. Octopus Energy will provide 100% renewable energy for the homes, with its Agile API facilitating half-hourly tariffs. Sero’s app will be used to control the energy network for each home, which includes a mix of smart energy technologies, including ground source heat pumps, thermal and electrical storage, and photovoltaic generation.

The app will enable residents to draw, discharge, and anticipate energy demands, enabling them to avoid relying on National Grid at peak times. This will ensure costs and carbon intensity are kept low. Using the preferences of residents, which could include room temperature or hot water needs, Sero will forecast energy demands as well as generation using intelligent software. This will control in-home energy storage and shift the impact of energy demands on the grid.
