SEC v30.0 implemented to align the UISS Target Response Times across SMETS2+ and enrolled SMETS1 Device Models

13 January 2021

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.

BEIS Response to Consultation on matters relating to the BEIS elements of the November 2020 SEC Release

27 November 2020

Today the Department for Business, Energy and Industrial Strategy (BEIS) published a response to its consultation of 23 October 2020. This consulted on the date for BEIS’ designations and re-designations to align with the November 2020 SEC Release, and on additional corrections to Smart Energy Code (SEC) Technical Specifications and Subsidiary Documents (SSDs) that BEIS proposed to designate or re-designate for inclusion into the SEC in the November 2020 SEC Release.

Please note that many of the documents that are being introduced by BEIS are being immediately further modified by SEC Modifications. Please refer to our news page here to see the final versions of these documents.

The BEIS changes to SSDs are needed to support relevant changes to energy licences and the main body of the SEC that BEIS has previously consulted and concluded on. These comprise changes to support the addition of Auxiliary Proportional Controller functionality and XML signing Certificates functionality. Included within the consultation response are directions to designate/re-designate SEC Technical Specifications and SSDs for BEIS-directed changes in the November 2020 SEC Release and to bring into effect a modification to SEC Section L3.18 that was suspended by BEIS’ X3.1 Direction of 18 September 2020. The purpose of this suspension was to prevent the issuing of XML signing Certificates until functionality to support them is introduced as part of the November 2020 SEC Release.

The BEIS consultation response and accompanying annexes can be found here.

 

What parts of the SEC will be (re)designated on 29 November 2020?

SEC designation implemented in support of the November 2020 SEC Release

7 October 2020

An updated version of the SEC came into effect on 7 October 2020 to implement a designation by the Department for Business, Energy and Industrial Strategy (BEIS) in support of the November 2020 SEC Release.

 

Background

In July 2020, the Data Communications Company (DCC) consulted upon proposed amendments to the SEC Subsidiary Documents (SSDs) that are required to support the November 2020 SEC Release, which includes BEIS directed changes.

The introduction of Additional SR Testing removes the requirement for specific UEPT-type arrangements for DCC functional releases, some of which were contained in the Common Test Scenarios Document (CTSD) itself, and some of which were set out as requirements for Eligibility Testing in the SMETS1 User Testing Services Approach Document (UTSAD), which is a document created under the SEC Variation Testing Approach Document (SVTAD) for SMETS1 Services.

Consequently, in August 2020, the DCC then consulted upon the proposal to remove the UTSAD under the SMETS1 SVTAD and make further consequential changes to the ETAD.

On 29 September 2020, the Data Communications Company (DCC) provided BEIS with its conclusion reports for both consultations and its final proposed changes to the CTSD, ETAD and SVTAD for SMETS1 Services. Having considered the DCC submission, BEIS is today designating new versions of the CTSD, ETAD and SVTAD for SMETS1 Services for incorporation into the SEC.

The BEIS designation letter and accompanying annexes can be found here.
