Greater domestic flexibility can significantly cut peak electricity demand, according to the results of a trial project.
The Crowdflex project, run by SSEN Distribution, National Grid ESO, Octopus Energy and Ohme, looked at how 25,000 households responded to price signals by reducing or increasing electricity demand.
The project found that customers on time of use tariffs saw reductions of up to 23% in the proportion of their daily demand consumed during the evening peak.
The project partners are now hoping to undertake future trials to investigate the reliability, consistency and the cost of domestic flexibility.
Geoff Down, Innovation Manager, National Grid ESO, said: “System flexibility is vital for future system operation and we’re encouraged to see that engaged consumers can, by participating in time of use tariffs, help manage and reduce peak electricity demand.”
"With the use of low carbon technologies in the home set to grow rapidly, this project helps us understand the exciting opportunities for us in the future.”
