The November 2021 SEC Release, due to go live on 4 November 2021, will contain DCC System impacting changes arising from SEC Modification Proposals. The following modifications are currently in scope:
The full scope of the release was baselined by the Panel on 14 May 2021.
SECMP0007 implementation approach
The SEC changes and Data Services Provider (DSP) elements for SECMP0007 will be implemented on 4 November 2021 (November 2021 SEC Release). The DCC and SECAS are proposing that the Communication Services Provider (CSP) system changes be delivered in the June 2022 SEC Release with the subsequent Communications Hub firmware updates being made as soon as they are available. The DCC is consulting on this approach with the industry before asking the Panel to endorse it.
Please note that Prepayment Meter Interface Devices (PPMIDs) and Home Area Network (HAN) Connected Auxiliary Load Control Switches (HCALCSs) can only be updated over-the-air (OTA) once the associated Communications Hub has its firmware updated to reflect the SECMP0007 solution. These updates will be rolled out following the June 2022 SEC Release as soon as they become available.
More information on this approach and what benefits Service Users can expect to see at each point can be found here.
Change to the SECMP0007 CTSD implementation date
On 25 March 2021, the SEC Panel wrote to the Authority requesting to change the implementation date of the SEC Appendix R ‘Common Test Scenarios Document’ (CTSD) legal text under SECMP0007 ‘Firmware updates to IHDs and PPMIDs’. The Authority approved this request on 1 April 2021 and the SECMP0007 CTSD legal text will now be implemented on 24 June 2021 (June 2021 SEC Release). The Panel’s letter to the Authority and the Authority’s response can be downloaded below.
