Automation Workflow for Dynamic Outage Map Generation and Public Facing Updates

During an outage, corporate communications and IT teams are manually collating data from SCADA, field crews, and customer calls to update static PDF maps—a process that takes hours and is instantly outdated. An autonomous workflow ingests these streams in real-time, renders a live geospatial visualization, and pushes it to the public-facing portal and CDN, eliminating the manual bottleneck and the associated 2-4 FTE hours of scramble per incident.

Up to 40% of outage-related calls are customers asking 'is my power out?' or 'when will it be back?'. A dynamic, public map that shows confirmed outage polygons and crew locations provides immediate, transparent answers. This deflects a significant volume of low-intent contacts, allowing agents to focus on critical care customers and complex issues, directly reducing average handle time and call abandonment rates.

Utilities are judged on communication clarity during service incidents. Manual, delayed updates erode trust and can trigger regulatory scrutiny. An automated, always-accurate public map demonstrates operational competence and a commitment to customer communication. This transforms the map from a cost center activity into a trust engine, directly supporting SAIDI/CAIDI metrics and improving CSAT scores post-event.

Dispatchers and field supervisors waste time cross-referencing multiple systems to understand the full outage picture. A live map that fuses OMS outage data with real-time crew GPS from workforce management systems provides a single pane of glass. This improves dispatch accuracy, reduces travel time between jobs, and allows for dynamic rerouting based on restoration progress, boosting crew productivity.

The workflow is built on a resilient orchestration layer (e.g., LangGraph) that polls the OMS for new outages, queries the GIS for feeder and customer mappings, and pings the MDMS for smart meter last-gasp signals. An agent validates and clusters this data, a geospatial rendering service (e.g., MapLibre) generates vector tiles, and a publisher agent pushes updates to a cloud storage bucket, triggering immediate CDN invalidation. The entire loop runs on a sub-60-second cycle.

A pilot begins by automating map updates for a single distribution district, with a human-in-the-loop approval gate before publishing. Phase 2 removes the gate for non-storm events and integrates crew GPS. Phase 3 adds predictive shading for at-risk areas based on weather feeds. Each phase includes rigorous monitoring for data freshness errors and automatic fallback to the last known good state, ensuring public-facing reliability.

The core workflow ingests and correlates live signals from the Outage Management System (OMS), smart meter last-gasp pings, SCADA fault indicators, and field crew GPS locations. An orchestration agent normalizes this data, maps affected customers to GIS circuit models, and calculates outage polygons. This replaces manual data calls between control rooms and GIS analysts, cutting map refresh latency from 15+ minutes to under 60 seconds.

A dedicated rendering agent takes the processed geospatial data and generates visualization tiles using libraries like Mapbox GL or Leaflet. It applies utility-branded styling, overlays restoration estimates, and pushes the updated tiles to a Content Delivery Network (CDN). The workflow includes versioning and rollback logic to ensure the public-facing map is always available, even during backend failures. This eliminates the manual, error-prone process of screenshotting internal systems and uploading to web servers.

Before publishing major updates (e.g., during storm events), the workflow routes the proposed map and associated messaging through a configurable approval layer. A supervisor agent can review for accuracy, or the system can require a human-in-the-loop sign-off from the Emergency Operations Center (EOC). All changes are logged with full audit trails to meet regulatory requirements for public communication accuracy. This balances automation speed with the necessary control for high-stakes information.

The generated outage polygons and restoration estimates are not just for visual display. The workflow automatically pushes this structured data to the mass notification system (e.g., Everbridge, SendGrid) and IVR platforms. This enables personalized, location-aware SMS/email alerts and accurate phone tree updates, creating a single source of truth for all customer-facing communications and eliminating contradictory information across channels.

The entire pipeline is instrumented for operational health. Monitoring agents track data freshness, API latency from source systems (OMS, GIS), CDN cache hit rates, and end-user map load times. Anomalies (e.g., OMS feed failure) trigger alerts to the NOC and can automatically fall back to a degraded but functional mode, such as displaying cached data with a timestamp. This ensures reliability matches the critical nature of the service during outages.

A practical build starts with a pilot on a single distribution division, integrating with a cloud-based GIS and the OMS's REST API. Phase 1 focuses on automated generation for internal dashboards. Phase 2 adds the CDN publishing layer and basic public map. Phase 3 integrates with communication systems and adds advanced approval workflows. This incremental approach de-risks the integration with legacy utility systems and allows for tuning based on real operational feedback.
