As the Electricity System Operator for Great Britain, National Grid ESO (NGESO) manages the connection and generation contracts that impact on the transmission system. We work closely with Transmission Owners (TOs) to support customer connections.

In this section, we’ve got everything you need to understand the connections process. Including what you need to do to connect to, or make use of the National Electricity Transmission System (NETS).

If you need any more help, please contact us.
