Question to the Department for Business, Energy and Industrial Strategy:

To ask Her Majesty's Government, further to the Written Ministerial Statement by Lord Callanan on 18 November (HLWS580), what estimate they have made of the additional power required from the National Grid to support their plans to increase the use of electric vehicles and to end the sale of new petrol and diesel cars and vans by 2030.

Each year BEIS publishes updated energy projections (UEPs), analysing and projecting future energy use and greenhouse gas emissions in the UK. The most recently published assessment (EEP 2019) included assumptions on the transition to electric vehicles and accounted for policies which were considered firm and funded by autumn 2019. Forthcoming energy projections will be updated to account for the latest policy decisions, including ending the sale of new petrol and diesel cars and vans from 2030.

We expect the transition to electric vehicles to create significant new demand for electricity but also offer opportunities for flexible management of the electricity system. Smart charging during off-peak periods, when electricity demand is low, can reduce peak demand and avoid triggering unnecessary network reinforcement. It can also maximise use of renewable electricity and can benefit consumers with cheaper electricity.
