Decision to Modify Licence held by National Grid Electricity System Operator in relation to Business Separation

Share the page

On 21 July 2022, we published a consultation on a proposal to modify Special Condition 1.1 (Interpretation and definitions) (‘SpC 1.1’) and Special Condition 2.7 (Prohibition on engaging in preferential or discriminatory behaviour) (‘SpC 2.7’) of the electricity transmission licence held by National Grid Electricity System Operator Limited ('NGESO').

We received two responses to the consultation. Following consideration of the responses, we have decided to modify SpC 1.1 and SpC 2.7 in the manner set out in the consultation, with minor housekeeping changes. The responses we received have been published on our website.

A licence modification notice under section 11A(1)(a) of the Electricity Act 1989 ('the Act'), detailing the modifications to SpC 1.1 and SpC 2.7, has been issued and is published alongside this decision.

These licence changes will take effect from 20 November 2022.
