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

To ask the Secretary of State for Business, Energy and Industrial Strategy, what proportion of UK energy supply the Government estimates will be comprised of interconnected capacity by (a) 2020, (b) 2030 and (c) 2040.

The proportion of electricity supplied by electricity imports in 2020 is expected to be 7.6%.

Projections for the power sector up to 2035 are published in the BEIS Energy and Emissions Projections 2017, which can be found here: https://www.gov.uk/government/publications/updated-energy-and-emissions-projections-2017

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.
