Objective: ArcGIS Utility Network Data Model Development
UDC is excited to share the progress of Ameren’s transformation to the Esri Network Information Management System. Ameren Gas and Electric began its modernization journey with UDC in 2018 with the replacement of the company’s GIS solution, which included the implementation of the Utility and Pipeline Data Model (UPDM) and ArcGIS Pipeline Referencing (APR) for its gas assets. Since then, Ameren and UDC have partnered on several data and modernization initiatives, including migrating the utility’s electric transmission assets to the ArcGIS Utility Network data model.
Following the data architecture reviews for gas transmission and distribution and electric distribution, completed in 2024, UDC and Ameren continued in this second phase to determine the effort and steps required to transition the utility’s maps and information products, system integrations, auto updaters, quality control scripts, and custom tools to the Esri Network Information Management System.
Project Goals
Ameren is preparing its data and infrastructure to leverage modern network information management features, including data-quality controls, enhanced editing and tracing, a service-oriented architecture, and increased out-of-the-box functionality. Through this transformation, Ameren aims to establish its Esri Network Information Management System as the system of truth for the organization.
In this phase, Ameren focused on designing and building data models as the foundation for future network information management initiatives. It has also developed a phased plan for migrating commodities to the new ArcGIS Utility Network model.
UDC’s Role
UDC configured ArcGIS Enterprise and the ArcGIS Pro extensions within UDC-hosted cloud environments. The results from previous data architecture reviews were used to conduct additional analyses of geometry and source data, ensuring that Ameren’s data quality meets the requirements of the intended ArcGIS Utility Network model. For the gas transmission data, geoprocessing tools were run to assess data readiness to support pipeline referencing.
Schema mappers were developed to support the future electric distribution data model and the combined gas distribution/transmission data model. Subnetworks were created from migrated data subsets, and ArcGIS Pro sandbox environments were configured to host the sample migrated datasets, enabling Ameren to gain experience with the new model using their own utility data.
This effort has provided Ameren with greater confidence in its data and GIS across the organization, as well as a comprehensive plan for moving forward with full Network Information Management System implementation.
