Ofgem is seeking views on how best to encourage domestic customers to provide demand-side response from devices such as electric vehicle chargers and heat pumps. The call for input comes as a new report from Cornwall Insight and Smart Energy GB highlights the tens of billions of pounds that households could save over the coming decades by using energy more flexibly. Ofgem said demand-side response will enable Great Britain’s rising electricity consumption to better match the growing output of intermittent renewable generators such as wind and solar farms, and is a key element in the government’s plan to decarbonise the electricity system by 2035.
