MP134A 'Use of SMKI Certificates relating to a SoLR event'

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.

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.
