Transmission Standard Framework

To implement the Offshore Transmission regime, modifications were made to the existing transmission licence and its associated codes in June 2009 and again in December 2010.

This work was carried out by Ofgem, National Grid and other related parties, under the general heading of standard framework development. This reflected the fact that this framework would be common onshore and offshore.

The government took powers in the Energy Act 2004 (EA04) so that the Secretary of State (SoS) would be able to make changes to the transmission licence and industry codes for purposes connected with offshore transmission. These changes were made with the commencement of the offshore regime powers under Sections 90 and 91 of the EA04.

Further information on the changes made can be found in our Offshore transmission consultation documents.

A number of working groups were set up to develop the modifications. More details can be found at:
