Grid Code

The Grid Code details the technical requirements for connecting to and using the NI System. Compliance with the Grid Code is one of the requirements of connecting and using the Transmission System.

As the code administrator for the Grid Code, SONI maintains and oversees any proposed changes to it. All changes must be reviewed by the Grid Code Review Panel, consulted upon and approved by the Authority.

For more information about the code please contact gridcode@soni.ltd.uk
