Written Question
Electricity Interconnectors
Friday 2nd November 2018

Asked by: William Cash (Conservative - Stone)

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

To ask the Secretary of State for Business, Energy and Industrial Strategy, what estimate he has made of the (a) amount and (b) proportion of UK electricity supply will be provide by interconnectors in (a) 2020 and (b) 2025.

Answered by Claire Perry

The proportion of electricity that will be supplied by electricity imports by 2020 is expected to be 7.4%.

The power supply sector is projected using the reference case scenario from the Energy and Emissions Projections 2017 (published January 2018), 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.

Written Question
Energy Supply: Prices
Thursday 1st November 2018

Asked by: William Cash (Conservative - Stone)

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

To ask the Secretary of State for Business, Energy and Industrial Strategy, what the average price is that interconnectors pay to use the electricity transmission network compared with the price paid by domestic generators of electricity.

Answered by Claire Perry

According to National Grid, the average transmission network use of system charge for a GB generator is £5.98 / kW (2018/19 tariffs). The actual tariff is dependent on the location of the generator, the historic load factor of the generator, the type of generator and details of its specific connection.

As interconnectors are part of the transmission network, they do not pay use of system charges for the network. Generators and consumers in different countries are liable for charges in those countries.
