This document sets out the application process and eligibility criteria for the upcoming Multi-purpose Interconnectors (MPIs) Pilot Regulatory Framework. We have included guidance on which types of projects would be considered eligible, what submission material applicants should include in their application, detail on the one-way reopener mechanism and how the pilot scheme interacts with other ongoing workstreams relevant to MPI regulatory development.

On 14 October 2022 Ofgem revised the “Multiple Purpose Interconnector Pilot Regulatory Framework” to include greater detail on the selection of the MPI Pilot projects, in paragraph 2.8, together with an updated timeline figure.

The MPI Pilot scheme will be open from 1 September 2022 to 31 October 2022. Please note that we are accepting applications for the third interconnector window and the MPI pilot in tandem.

Further details on our needs case assessment framework for the Initial Project Assessment stage and how we plan to target the pilot scheme was be published in summer 2022.

Subsidiary guidance dated 14 October 2022 titled “Supplementary application submission guidance for Third Window and the MPI Pilot” offers clarification on the submission of documents.

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

On 31 August 2022 Ofgem contacted stakeholders to inform them of our decision to provide one new high level cost assessment template for all applicants of the third investment round for interconnectors, including the MPI Pilot. As a result of the consolidation of the MPI Pilot and Third Window templates, there were some inconsistencies, which required correction. These have been documented in the supplementary application submission guidance and a revised version of the cost assessment template has been provided on 14 October 2022.
