FLATLINE – smart optimisation of low-carbon technologies
FLATLINE explored how smart, coordinated optimisation of low-carbon technologies could reduce energy bills and provide flexibility to the National Grid.
Heat pumps, battery storage and solar PV were installed in 20 homes in two specially built developments, with Passiv providing smart control and optimisation.
The project showed that by optimising to time of use tariffs, energy bills could be reduced by around £220 per year, while at the same time providing valuable flexibility to the National Grid.
The FLATLINE (Fixed Level Affordable Tariffs Led by Intelligently Networked Energy) project explored how smart, coordinated optimisation of low-carbon technologies could enable demand from homes to be ‘time-shifted’ to better align with energy generation, reducing energy bills and providing flexibility to the National Grid. The project was led by Sero Energy with Passiv and Minus7 as partners.
FLATLINE saw heat pumps, battery storage and solar PV installed in 20 homes in two specially built developments, The Mill in Cardiff and Parc Eirin in Tonyrefail. These installations served as a proof of concept for deployment of multiple low-carbon technologies in homes. Passiv used its Smart Energy Platform and multi-asset controls to optimise the technologies installed according to time of use tariffs to reduce energy bills while optimising network capacity for the National Grid.
FLATLINE demonstrated how careful management of low-carbon technologies can shift household energy consumption to avoid periods of peak demand. By optimising to time of use tariffs, the battery reduced energy bills by around £220 per year, a reduction of 25%. The average carbon emissions saving at Parc Eirin were estimated at 71 tonnes a year - the equivalent of the emissions produced by 15 cars.
As part of the FLATLINE project, the Passiv Smart Energy Platform provided demand side response services enabling energy users to automatically reduce their electricity consumption in response to an incentive from the network operator. The project saw the successful delivery of two demand side response scenarios – ‘no-net-import’, where the homes used their stored energy rather than drawing from the grid, and ‘negative import’, where the homes actively exported energy back to the grid.
