Between 13 January 2023 and 10 February 2023 [1] , DCC consulted on an amended version of SEC Appendix AM ‘SMETS1 Supporting Requirements’ (and its annex Device Model Variations to Equivalent Steps – DMVES) to implement changes relating to the behaviours of a range of SMETS1 meters. Today, the Department issued its letter of approval and direction designating a new version of the S1SR.
