Latest update
SECAS will present this modification to the SSC on 8 May 2024 for discussion. The Refinement Consultation for this modification has now closed. SECAS will present this modification CSC on Tuesday 21 May 2024 to progress to the Opine phase.
What is the issue?
The Data Communications Company (DCC) Systems have a limit to the amount of firmware images that can be processed meaning that if a significant volume of large firmware images needs to be processed, they must be spread over several days. Some Electricity Smart Metering Equipment (ESME) have a very large firmware image, in excess of 750kB that requires being broken down into multiple images. The current processing of these images is possible at maximum capacity of 12,000 images a day.
What is the solution?
The solution clarifies that if a firmware image for a SMETS1 Device is larger than 750kB and the User wants to send a batch larger than 500 images per day, the User needs to contact the DCC through the DCC Service Desk to coordinate and agree on a delivery schedule. Once this delivery schedule is agreed, the five-day TRT will still apply from the point of sending each batch.
The proposed change to the legal text for this is placed in SEC Appendix E ‘DCC User Interface Services Schedule’ (UISS).
