The question

To ask the Secretary of State for Energy Security and Net Zero, what assessment his Department has made of the potential impact of heat pump deployment on winter peak electricity demand.

Answered by Martin McCluskey

The Department assesses that heat pump deployment, as part of the wider electrification of heat, is expected to increase annual and winter peak electricity demand over time. The precise impact depends on factors including the rate of deployment, heat pump performance, weather conditions and the availability of consumer-led flexibility. The Department models a range of plausible future demand trajectories to ensure that the electricity system remains flexible, resilient, and able to maintain security of supply under different pathways to net zero.
