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

To ask Her Majesty's Government what estimate they have made of future electricity storage requirements resulting from increased generation of electricity from intermittent sources.

BEIS’s 2017 Energy Emissions projections outlines that 11GW of electricity storage could be deployed in Great Britain by 2035 under the Reference Scenario. Up to 2020, the reference scenario reflects current power sector policies. Beyond 2020, the reference scenario includes assumptions that go beyond current Government policy. The results do not indicate a preferred outcome and should be treated as illustrative.
