Department for Energy Security and Net Zero: decision on DCC’s proposal to re-designate SMETS1 TMAD with clarifications to SMETS1 TMAD Clause 18 and on DCC’s draft Decommissioning Timetable for the Requesting Party services in respect of the SMETS1 IOC cohort

In April 2023 DCC consulted on its proposals to amend the ‘Excluded Category – Duplicate MPANs and MPRNs’ in Clause 18 of the SMETS1 Transition and Migration Approach Document (TMAD) and designate the amendments into the SMETS1 TMAD. The amendments also supported the DCC’s recommendation to the Secretary of State and the Department of the draft Decommissioning Timetable for closing the Requesting Party service in respect of the Initial Operating Capability (IOC) cohort on 28 May 2023.

Today, the Department issued its letter of approval, dated 17 May 2023, for re-designating the amendment into the SMETS1 TMAD and for the DCC’s proposed draft Decommissioning Timetable

Activities to close the Requesting Party service would begin on 29 May 2023, provided, that all in-progress migrations have concluded. The final Decommissioning Timetable was provided by the DCC to the Department today here.
