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

To ask the Secretary of State for Business, Energy and Industrial Strategy, what estimate the Government has made of the proportion that gas-fired generation will form of the new proposed 14GW of electricity interconnection to be developed by 2023.

The Government has not made an estimate of the proportion of electricity imports on interconnectors that will have been generated by gas-fired generation.

Electricity interconnection connects Great Britain’s energy market to the markets of neighbouring countries, enabling electricity to be traded. It is not possible to trace the precise source of the electricity transported through interconnectors; the electricity that we import will have been produced by the mix of generation technologies connected to the exporting country’s transmission network. The precise generation mix that provides the imported electricity at any point in time will depend on a complex set of factors and, in particular, will vary depending on the characteristics of the exporting market.
