Project Duration: 06/2025 – 12/2025
Objective: Utility Network Data Model Development
UDC is excited to share the progress of Ameren’s digital transformation to Network Management. Ameren began its modernization journey with UDC in 2018 with the implementation of Esri’s 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 Utility Network data architecture reviews for gas transmission and distribution and electric distribution completed in 2024, UDC and Ameren have teamed up 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 Utility Network and ArcGIS Pro. UDC is working closely with Ameren’s IT and Business teams on these initiatives, which are set to wrap up next month.
Project Goals
Ameren is modernizing its systems and infrastructure to leverage the Utility Network’s high-value features, which include advanced network modeling, high data quality standards, enhanced editing and tracing capabilities, a service-oriented architecture, and increased out-of-the-box functionality. Through this transformation, Ameren aims to establish its GIS as the system of truth for the organization.
In this phase of Ameren’s digital journey, the focus is on designing and building the data models that will serve as the foundations for future Utility Network implementations. Additionally, Ameren will have in hand a phased implementation plan for moving its commodities to the new data model.
UDC’s Role
For these initiatives, UDC configured ArcGIS Enterprise and the ArcGIS Pro extensions within UDC cloud environments. The results from the previous data architecture reviews were then leveraged to conduct additional geometry and source data analyses to ensure Ameren’s data quality meets the high standards of the Utility Network model. For the gas data, APR geoprocessing tools were run on migrated linear referencing features to assess the data readiness of those features.
UDC additionally developed schema mappers for the future electric distribution data model and combined gas data model, configured subnetworks using migrated data subsets, and created and configured ArcGIS Pro Project sandbox environments for the teams to view and interact with their specific datasets in the model.
This effort has provided Ameren with higher data quality, increased confidence in the data and GIS across the organization, and a comprehensive plan for moving forward with full implementation.
