Grid Code

The Grid Code is the technical code for connection and development of the National Electricity Transmission System (NETS).


The Grid Code Review Panel (GCRP) is a standing body established and maintained by National Grid in accordance with the General Conditions of the Grid Code. The GCRP, under normal circumstances, meetings every other month.  It will convene ad-hoc meetings when required. 

The Panel is made up of members from across the industry who have an interest in the development of the Grid Code and its aims include keeping the Grid Code and its working under review, discussing and reviewing suggestions for amendments to the Grid Code, and issuing guidance in relation to the Grid Code.
