Snohomish County PUD Uses Network Model Management Solution for Entire Grid

To feed its advanced distribution management system with timely and accurate data, Snohomish County PUD implemented Intergraph G/Technology to create a single system of record for its entire network and provide information to all departments and systems.

The Challenge

As the second largest publicly owned utility in Washington, Snohomish County Public Utility District (SnoPUD) serves more than 348,000 electric and 20,000 water customers. SnoPUD engaged in a smart grid project partially sponsored by the U.S. federal government to deploy an advanced distribution management system (ADMS). Critical to the success of any ADMS deployment is accurate, timely network data. To feed this data, SnoPUD needed an enterprise system that featured at its core a with single system of record of the network to provide information to all departments and systems – not only the ADMS, but also SAP and others.


The Solution

SnoPUD adopted Hexagon Safety & Infrastructure’s Intergraph G/Technology for its extensive capabilities and lifecycle support for grid data. The solution serves as the system of record for work and asset location information, providing source data to SnoPUD’s GE ADMS and SAP systems. The product’s database-centric architecture drives network model management. SnoPUD uses the solution to merge its as-built network with its as-operated model to make daily corrective measures to its services.
