We are becoming a separate company

In April 2019, the Electricity System Operator is becoming a separate company within the National Grid Group. Find out more about what this change will mean.

Grid Code

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

Grid Code Elections were launched on 11 September 2018 and  the new Panel will be in post from 1 January 2019 until  31 December  2020. 

This is to advise you that that the Grid  Code Election process has been extended for a further period as per time table below.

The timetable below outlines the key indicative milestones in relation to the election process, and gives you the opportunity to be nominated to sit on the Panel, along with the Guidance on the process and how to vote in this year’s Election should we receive more nominations than the elected seats.

As Code Administrator we are on hand to talk you through any questions you may have around the process, and also provide information on the role and responsibilities of a Panel Member, so please do not hesitate to get in touch if you are interested or have any questions by emailing the Grid Code dedicated mailbox ([email protected]) or you can contact me directly on ([email protected]).

The Grid Code specifies technical requirements for connection to, and use of, the NETS. Compliance with the Code is a requirement under the Connection and Use of System Code (CUSC).

We maintain the Grid Code and serve as its administrator. All changes are subject to industry consultation and approval by Ofgem.

Find out more about connecting to the NETS in our Electricity connections pages.

Please refer to the Electrical standards page for documents and details relating to electrical standards and specifications for electronic data communications facilities.
