This document sets out the cap and floor regime application process for the upcoming third application window for new regulated interconnectors, following our Interconnector Policy Review decision from December 2021. We have included guidance for potential applicants on eligibility and submission criteria for the Initial Project Assessment stage.

We also propose a new timelines and incentives framework for the third application window to improve our treatment of project delays. Our preliminary positions are outlined in this document, which will be subject to further consultation.

The third window will be open from 1st September to 31st October 2022. Please note that we are accepting applications for the third window and the Multiple Purpose Interconnector (MPI) pilot regulatory framework in tandem, more detail on the MPI pilot can be found in a separate guidance document.

Further details on our needs case assessment framework for the Initial Project Assessment stage, and how we plan to target the third window will be published in summer 2022.

Please send any feedback, questions, or completed applications to Cap.Floor@ofgem.gov.uk.
