We are a separate company

European network codes

The Third Energy Package of European legislation created a requirement for European network codes (ENC), covering grid connections, markets, and system operation. The codes are designed to provide a sustainable, secure and competitive electricity market across Europe.

Changes to the GB electricity codes to implement part of a European code or guideline will be managed through the normal GB code modification processes, with timely delivery overseen by Panels.
