Implementation date

Latest update
Following discussions with the Security Sub-Committee (SSC), the Proposer and the SSC agreed that the business case was not strong enough to continue with the modification in its current format. The Proposer notified SECAS on 10 November of their intention to withdraw this modification. This modification has now been withdrawn.
What is the issue?
Only the relevant Supplier (or their agent) holds the SMKI Private Keys that enable Critical Commands, such as Emergency Credit, to be sent and actioned by the meter. It can commonly take between two and four weeks from the point of SoLR appointment for the new Supplier to change the SMKI Certificates and much longer in some instances where there are problems with data and communications. During this time Prepayment meter customers may be off supply.
What is the solution?
The Proposed solution applies mainly where a failing Supplier exits the market without ensuring their PPM customers are protected from losing energy supply. It seeks to enable the SMKI PMA to facilitate the ongoing use of the failed Suppliers SMKI certificates until all PPM customers are protected from loss of supply or the incoming SoLR takes responsibility for those customers. This will be a DCC System solution.
