An updated version of the SEC came into effect today, 13 January 2021, to implement a modification to SEC Appendix E ‘DCC User Interface Services Schedule’ (UISS) made by the Department for Business, Energy and Industrial Strategy (BEIS).
This is to align the Target Response Times within the UISS across Smart Metering Equipment Technical Specifications 2+ (SMETS2+) and enrolled SMETS1 Device Models.
Paragraph 3 of the UISS previously restricted the Target Response Times for Scheduled Services to SMETS2+ Devices only. This restriction has been removed, making the Target Response Times applicable to SMETS1 and SMETS2+ Devices, thereby making sure that the regulatory framework reflects the system behaviour.
The accompanying documents can be found via the following links:
- BEIS designation letter
- Annex A: SEC Appendix E ‘DCC User Interface Services Schedule’ v5.0
- Annex B: SEC Appendix E ‘DCC User Interface Services Schedule’ v4.0 mark-up
