SEC v63.0 released to implement MP209

1 August 2022

An updated version of the SEC came into effect on 1 August 2022 to implement MP209 ‘Lifetime CPA Certificates’.


MP209 will enable new Lifetime CPA Certificates that will not expire, but will need to be renewed, to be accommodated by the SEC. This will be accompanied by updates made to the CPL Guidance Notes to advise Device Manufacturers, Suppliers and the DCC how to highlight whether the Certificate expires or requires renewal.


What parts of the SEC were affected?

The following parts of the SEC were affected:

  • SEC Section F ‘Smart Metering System Requirements’
  • SEC Appendix Z ‘CPL Requirements Document’

Additionally, we have made corrections to Section L ‘Smart Metering Key Infrastructure and DCC Key Infrastructure’. These corrections are to rectify an error that had been introduced when SEC v57.0 was designated which had inadvertently omitted changes introduced by MP173 ‘SMKI and DCCKI Document Set reviews’.
