SEC Version 6.13 Designated

14 June 2019

Today, on 14 June 2019, SEC v6.13 was designated.

On 15 April 2019 the Data Communications Company (DCC) published a consultation on a new Migration Testing Approach Document (MTAD) for a SMETS1 service and associated amendments to SEC Appendix AK ‘SEC Variation Testing Approach Document for SMETS1 Services’ (SVTAD) in support of testing of the migration solution for a SMETS1 service.

Following consideration of stakeholder responses, BEIS have decided to:

  • approve the MTAD; and
  • incorporate the amended version of the SVTAD into the SEC.

The Government response to this consultation and associated documents, including redlining for the SVTAD can be found here. The MTAD can also be found on our Developing SEC webpage here.
