STOP PRESS: As of 1 April 2019, National Grid Electricity System Operator (NGESO) became a separate legal entity within the National Grid Group, separating the system operator (SO) and transmission owner (TO) roles previously held by National Grid Electricity Transmission plc (NGET). NGESO now takes on the role of SO, while NGET will continue to act as TO. As a result, this Practice Note is currently being updated. For more information on the effect of the split, see Practice Note: The Split of National Grid’s Transmission Owner (TO) and System Operator (SO) Roles and Licences.

What is a grid connection?

A grid connection allows a user to connect to the local network or ‘grid’ so they can receive or produce electricity. A connection agreement is key to an ongoing connection and the ability to import or export power from the grid.

Whether a developer building a small housing development or a power company building a nuclear power station, a grid connection is required whenever there is no existing connection in place.

A new connection is usually obtained through a contract for the construction of a grid connection (a construction agreement). Where projects are project financed it is usually a condition precedent to financing arrangements given its necessity for the viability of the project.
