Interconnector policy review: Working paper for Workstream 4 - multiple purpose interconnectors

In August 2020, Ofgem launched a review of its regulatory policy and approach to new electricity interconnectors. The objectives of the review are two-fold: firstly, to establish whether there is a need for further GB interconnection capacity beyond those projects currently with regulatory approval; and secondly, to consider Ofgem’s approach to the regulation of future GB interconnection. The review has been broken down into four workstreams considering specific aspects of regulatory policy and decision-making. This working paper consultation is for Workstream 4 review. We also published our working paper for Workstream 3 today, and the working papers for Workstreams 1 and 2 were published on on 18 June 2021 and can be found in the related links.

This working paper summarises our analysis, findings, and provisional recommendations from workstream 4 – Multiple-purpose Interconnectors. In this workstream we have looked at whether the final conclusions of our Integrated Transmission Planning and Regulation (ITPR) project on MPIs remain fit for purpose. We also considered whether our regulatory approach for point-to-point (P2P) interconnectors, the cap and floor regime, could potentially be used for the regulation of MPIs. We have considered this alongside our ongoing work on offshore coordination with government, National Grid ESO (NGESO) and others through the Offshore Transmission Network Review (OTNR).

We are now seeking stakeholder feedback on our analysis, proposed conclusions and initial proposals set out in this public consultation. We will then consolidate the findings across each workstream into a single decision paper, which will provide our final proposals for the future regulation of interconnectors in GB.
