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.

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.
