Methods, systems, and computer program products for prioritizing errors in connectivity models of distribution networks are provided herein. A computer-implemented method includes collecting geo-spatial data arising from each of multiple transformers and multiple customer meters within an electric power distribution network; collecting load data arising from each of the customer meters within the electric power distribution network; assigning one of the transformers to each of the customer meters that is not presently assigned to one of the transformers according to a connectivity model for the distribution network, wherein said assigning is based on the collected multiple items of geo-spatial data and the collected load data; computing an error probability attributable to each of the transformers and the customer meters assigned thereto within the electric power distribution network based on multiple variables; and modifying an existing field inspection schedule corresponding to the electric power distribution network based on said computing.
