On 1st February 2018, BEIS concluded on a consultation on the renaming of SMETS documents, the incorporation of various schedules and subsidiary documents and related transitional variations to the SEC, including:

  • changes to the Smart Metering Equipment Technical Specifications (SMETS) naming conventions;
  • introducing a suite of new Schedules and Subsidiary Documents to the SEC in advance of Release 2.0, in order support the introduction of Dual Band Communication Hubs. Related Transitional Variations* are also being introduced to support the early introduction of Release 2.0 documents; and
  • introducing additional SEC Schedules in order that SEC Party Modification Proposals can be raised against them for implementation in future SEC Releases.

*Please note that pursuant to SEC Section X3.6, DUIS V2.0 and MMC V2.0 have been designated and incorporated into the SEC, but no Party shall be entitled to exercise the rights set out in them, nor obliged to comply with the obligations set out in them.

As a result SEC v5.13 came into effect on 1st February 2018, with the four documents being re-designated and several documents being designated to sit alongside existing versions.
