MP188 approved and implemented in SEC v55.0

23 December 2021

On 22 December 2021, the Change Board decided to approve MP188 ‘Temporary Communications Hub Ordering and Delivery Rules extension’. An updated version of the Smart Energy Code (SEC) came into effect today, on 23 December 2021 to implement MP188.

The Data Communications Company (DCC) considered that an extension to the validity period of the Temporary Communications Hub Ordering and Delivery Rules (TCHODR) should be granted, so that requirements on 2022 orders could be amended and Communications Hub volumes secured. This document was set to expire as of 1 January 2022 but the end-date on the TCHODR has now been removed by MP188. Instead, any requirements set out within the TCHODR will include a specific end date agreed by the Panel following consultation.

The DCC has further developed the TCHODR to account for the 2022 orders. This took place separate to this modification through industry engagement and consultation. On 17 December 2021, the SEC Panel signed off these changes as per the process set out in SEC Section F5.1A.
