As is the case in many utilities, the association between customer meters and transformers is one area where there are known inaccuracies. Public Safety Power Shutoffs (PSPS) have highlighted the need to correct this association so that the correct set of customers can be notified in advance of a safety shutoff. Manual inspection of all of PG&E’s 5.4 million meters is infeasible, so an alternative approach was needed. A project to automatically identify misassignments, recommend corrections, and prioritize workflows to review and correct errors has been implemented.
This project has been informed by the initial work that was done as part of an Electric Program Investment Charge project in which analysts from PG&E and several other vendors evaluated the potential for a fully automated solution. Unfortunately, this evaluation determined that though the algorithms were able to find and accurately correct some mis-assignments, the number of incorrect outcomes outweighed the correct ones. Without a fully automated solution, a human in the loop solution was implemented to enable the issue to be mitigated prior to the availability of a sufficiently accurate algorithm.
