MP160 Certificate Signing Request forecasting

StageRefinement Process
Implementation date Unknown
Latest update On 18 June 2021, the SEC Panel agreed that DP160 should be converted into a Modification Proposal and enter the Refinement Process. SECAS will now work with the Proposer to develop the solution.

What is the issue?

Smart Energy Code (SEC) Section L ‘Smart Metering Key Infrastructure and DCC Key Infrastructure’ currently sets out the obligation whereby each Party which is an Authorised Subscriber shall provide the DCC each quarter with a forecast of the number of Certificate Signing Requests (CSRs) it expects to send in the following eight months. The forecasts contain a breakdown of the total number of CSRs for Device Certificates, including the issue of a single Device Certificate and ones that are batched together.
The DCC believes that the obligation on Users to provide these forecasts should be removed. There is sufficient capacity within the Smart Metering Key Infrastructure (SMKI) services to no longer require the CSR forecasting process except in the case when exceptional volumes of CSRs are to be sent in a given period by a SEC party.
