The GIS model will give utilities the advantage of viewing the flow of electrical current during a power outage. This helps determine possible breaks in electrical service. A cooperative can also use a flow model to determine a possible change (re-route option) in flow direction by changing a switch position to provide power to customers during extended service disruptions.

Through the database, users can view plant assets, evaluate sites, and plan projects using a desktop or GIS portable device, saving time and money. Combined with high-resolution aerial imagery, the GIS offers a powerful way of storing information. Rather than relying on paper maps or CAD drawings, the intelligent data combined with spatial accuracy in the GIS display precise information.

Once data collection is complete, the information is thoroughly verified. Visual checks identify missing features, incorrect rotation, poor placement, incorrect devices or symbols, and mistaken cable phases. They also verify that transformers are positioned at all primary and secondary cable intersections. Automated checks identify problems related to duplicate line section values, cable end point switches, individual devices, and connectivity issues.

The justification for the GIS is not in the improvement of the mapping process, but as one of the enablers for fundamental and perhaps radical process improvement and its associated savings in cycle time, asset utilization, and productivity.
