SMETS1 Consultation on changes to the SMETS1 Supporting Requirements

A DCC consultation on changes to Clause 17 and Clause 18 of the SMETS1 Supporting Requirements (S1SR) that records certain Device Specific Behaviours.

DCC has identified new device specific behaviours for the IOC, MOC and FOC cohorts that have arisen out of testing. DCC has proposed changes to clauses 17 and 18 of the SMETS1 Supporting Requirements (S1SR) to make provision for these device specific behaviours.

On 5 November 2021 DCC is consulting on the proposed changes to the S1SR, which consultation closes on 3 December 2021.
