GC0120 - National Grid legal separation changes to clarify Grid Code responsibilities and consequential changes

GC0112 ‘National Grid Legal Separation Grid Code changes to incorporate NGESO’ was approved for implementation by the Authority on 3 December 2018. This will be implemented on 1 April 2019. GC0112 will modify the Grid Code to reflect the creation of a new National Grid Electricity System Operator (NGESO) titled ‘The Company’ that is legally separated from
National Grid Electricity Transmission Limited (NGET) throughout the Grid Code in order to ensure the System Operator and Transmission Owner obligations are clear.

Prior to the approval of GC0112, there were four active Grid Code modifications, namely GC0097, GC0098, GC0099 and GC0104, whereby the legal text baseline used, did not take into account the changes that will be implemented by GC0112. As a result, incorrect references remain in the Grid Code in relation to which party is responsible for some of the
obligations within the Grid Code. GC0120 is proposing to rectify these incorrect references, which can be found in section 2 and the legal text in Annex 1.
