Summary: Municipal and electric cooperative utilities must transition from ArcMap and the legacy Geometric Network to Esri’s Utility Network to remain on supported platforms. Success isn’t about size—it’s about data maturity, governance, and planning. A structured, right-sized approach helps smaller utilities modernize connectivity modeling, improve outage response, and build a sustainable GIS foundation aligned with real-world operations.
When an outage hits, there’s no time to second-guess the map.
Crews need to know what’s connected, what’s energized, and what’s downstream. Dispatch needs clear answers. Engineering needs confidence that rerouting power during an outage won’t create new risks or unintended outages.
If your GIS can show assets but can’t reliably trace connectivity or model system behavior, those decisions get harder—and riskier.
That’s the problem the Esri ArcGIS Utility Network (UN) was designed to solve. It brings structure, validation, and traceability to utility GIS data so it can reliably support real-world operations.
For municipal utilities and electric cooperatives, moving to the UN isn’t a matter of preference. With ArcMap and the legacy Geometric Network retired in 2026, continuing on unsupported platforms is no longer viable. The real question now isn’t whether to move, it’s how to move in a way that aligns with your size, resources, and operational realities.
Utility Network Readiness Is About Data Maturity—Not Headcount
The Utility Network modernizes how connectivity and system behavior are modeled inside ArcGIS. It strengthens tracing, validation, and subnetwork management so utilities can rely on their data when it matters most.
For smaller utilities, the concern is often capacity. But readiness has far less to do with team size and much more to do with data maturity and governance.
Smaller utilities succeed with the UN when:
- Asset data is accurate enough to support operational decisions
- Connectivity is represented consistently
- Editing standards are defined and followed
- GIS, engineering, and field teams agree on how the network should behave
Team size influences how quickly a project progresses. It does not determine whether the UN will succeed long term. In lean organizations, the added structure and validation can reduce reliance on institutional knowledge and increase operational confidence.
The 2026 Retirement Is a Planning Moment
As the industry moves beyond the legacy Geometric Network, utilities need a supported, future-ready network model. For smaller municipal and co-op utilities, that shift directly affects:
- Outage response
- Switching validation
- Planning and analysis
- Integration with other systems
- Long-term maintainability
Waiting may feel easier in the short term, but it often leads to compressed timelines and reactive decision-making. Utilities that approach migration with a structured plan have more control over scope, budget, and internal alignment.
What “Ready” Really Looks Like
You do not need a large GIS department to prepare for the UN. You need clarity in a few key areas.
- Asset Integrity: Device types, statuses, and critical attributes are reliable enough to support tracing.
- Connectivity Confidence: Assets connect in a consistent, traceable way—even if cleanup is required.
- Defined System Behavior: Phases, terminals, and isolation points can be modeled intentionally rather than assumed.
- Governed Editing Practices: There is a clear, consistent process for updating the map so data quality does not degrade over time.
- Operational Alignment: GIS and operations share a common definition of what “correct” looks like.
Most smaller utilities find they are strong in some areas and weaker in others. That’s normal. Gaps are not disqualifiers; they simply shape the migration plan.
Keep It Practical: Configure First
One of the most common pitfalls is overcomplicating the model.
The UN offers powerful capabilities, but not every organization needs advanced configurations on day one. A configuration-first approach—using standards-based device behaviors, terminal configurations, and subnetwork controllers—keeps the system maintainable.
Customization should be intentional and tied to clear operational value.
For smaller utilities, maintainability matters more than sophistication. A well-configured model that your team understands and can support will deliver far more value than an overengineered system that becomes difficult to manage.
Utility Network Should Support Real Work
The UN is not just a GIS enhancement. It’s an operational tool. When implemented well, it supports:
- Faster upstream and downstream tracing
- More confident switching validation
- Clearer outage isolation
- Better visibility into energized states
When the model reflects how your crews and engineers actually work, adoption improves, and the return on investment becomes tangible. That alignment should be part of planning, not an afterthought.
Plan for Sustainability, Not Just Go-Live
For smaller utilities, long-term sustainability is critical. You may not have a large IT team or a dedicated UN architect. Institutional knowledge may sit with one or two key individuals.
A successful UN migration focuses on:
- Clear data governance ownership
- Maintainable integrations
- Defined editing standards
- A model your team can confidently support
The goal is not simply to migrate. It is to modernize in a way that reduces technical debt and strengthens operational clarity.
A Structured, Right-Sized Path Forward
Every utility’s starting point is different. Some need a focused readiness checkpoint and standards-based configuration. Others require deeper discovery, data remediation, and governance support.
That’s why the Epoch UN Blueprint is designed to scale based on your organization’s size, data maturity, and goals.
The Epoch UN Blueprint can be aligned to your needs and your budget. Whether the priority is accelerating to a production-ready model or building a comprehensive, future-state design with stronger governance and validation, the approach remains structured and proven.
By leveraging the Epoch UN Blueprint, utilities benefit from:
- A repeatable migration framework grounded in UN best practices
- Standards-first configuration that prioritizes maintainability
- Data readiness guidance and QA/QC support
- Clear architectural direction before irreversible decisions are made
- Support from experienced, Esri-certified professionals
For municipal and electric cooperative utilities, that flexibility matters. It allows you to move forward at the right pace, with the right level of support, without overwhelming internal resources.
Utility Network is not reserved for large utilities. With a structured, right-sized approach, smaller utilities can modernize confidently to improve connectivity modeling, strengthen operational visibility, and build a sustainable foundation for the future.

ArcGIS Utility Network Migration for Small and Mid-Sized Utilities
Esri’s ArcGIS Utility Network is a modern GIS framework that models how utility assets connect and behave. It enables accurate tracing, validation, and subnetwork management so utilities can support outage response, switching decisions, planning, and analysis with more reliable connectivity data. It replaces the legacy Geometric Network retiring in 2026.
No. Migration is required to remain on supported platforms, and success is not determined by customer count. Smaller municipal and cooperative utilities can successfully transition when they focus on data maturity, governance, and a structured migration plan aligned to their operational needs.
The greatest risk is treating the migration as a one-time data conversion rather than an operational modernization effort. Without clear governance, editing standards, and ownership, data quality can erode over time, reducing the long-term value of the Utility Network.
Migration establishes the supported network foundation, but integration planning should occur alongside it. Aligning GIS, outage management, and other enterprise systems during migration helps ensure long-term sustainability and prevents costly rework after go-live.
It means using Utility Network’s built-in configurable capabilities—such as terminal configurations and subnetwork controllers—before developing custom logic. This approach keeps the model simpler, easier to maintain, and more sustainable for smaller utilities with lean internal teams.
