DR 0124 – Working Practice 0013 Document the procedure to be used to terminate Meter Point Reference Numbers identified as duplicates

There are a small number of sites where a duplicate MPRN has been set up and registered to a supplier
and this has occurred because, as part of an increased connection process at the site or the wrong
Service Product was applied in Networks ISU and a second MPRN was created for the site that was
subsequently energised. There is a requirement to de-register and terminate these duplicate MPRNs as
and when they are identified by Market Participants and this Working Practice was developed to
establish a common procedure between ESB Networks and Suppliers to de-register these sites.
Working Practice 0013 originally issued from RMDS, and was discussed at the IGG Meeting held on 21st
September 2006 where a number of issues were raised by Market Participants.
Working Practice 0013 v1.0 was circulated to Market Participants on 2nd November 2007 and following
feedback from one participant, a note has been included in step 6.
