Presentation · EN — A February 2026 Siemens Energy Grid Technologies one-pager deck (version 1.0) presenting the three offerings of the Noedra Flow suite for overhead-line digitalization under the tagline 'Intelligence from above the grid'. One slide each covers: Dynamic Line Rating (DLR) / Ambient Adjusted Ratings (AAR) — line-mounted sensor networks and analytics that continuously compute the safe real-time capacity of overhead lines, supporting FERC 881 compliance and deferral of costly upgrades; Situational Awareness & Weather Resilience — real-time detection and alerts for icing, abnormal vibration (galloping, aeolian), and extreme weather events; and Advanced Inspection — helicopter, drone, and ground-based multi-sensor data acquisition (Ultra-HD RGB, 3D LiDAR, infrared, UV/corona) with AI analytics for vegetation management, automated asset inventory, defect detection, and centimetric-accuracy surveying. Each one-pager follows the standard main-benefits / features-at-a-glance / technical-information layout with experience and version stamps.
DLR / AAR use advanced sensor networks and analytics to continuously assess the safe, real-time capacity of overhead lines, enabling operators to maximize asset utilization, ensure regulatory compliance, and make smarter operational decisions (slide 1).
Main benefits as printed: real-time capacity optimization — operators safely maximise line capacity based on actual conditions rather than static limits, unlocking hidden capacity and deferring costly upgrades; regulatory compliance — supports regulations such as FERC 881 by adjusting ratings based on real-time ambient temperature; predictive maintenance — continuous monitoring of the physical behaviour of overhead lines (conductor condition, sag, tension, galloping, ageing, ice formation) provides early warnings and data-driven maintenance planning to reduce unexpected failures.
Technical information: real-time ampacity calculation uses sensors mounted directly on overhead lines to measure conductor temperature, wind speed/direction, current, and ambient conditions. Dashboards, alerts, and 'what-if' simulations deliver real-time visibility, bottleneck identification, and proactive decision support — operators can evaluate scenarios, anticipate constraints, and proactively optimise line performance.
| Feature | Description (slide 1, 'Features at a glance') |
|---|---|
| Real-time monitoring | Current, conductor temperature, wind speed/direction, humidity, and ambient temperature; optional cameras for inclination and visual inspection |
| Analytics | Automated algorithms for Dynamic Line Rating and Ambient Adjusted Rating; sag, tension, galloping, ageing, and ice detection; AI-powered vegetation management and wildfire detection |
| Data processing | Continuous measurement and correlation of line parameters; diagnostics, prognostics, and trending for incipient failures; overload guidance |
| Connectivity & security | Encrypted data to web dashboards; API integration with SCADA and asset management systems; supports standard protocols for seamless integration |
This offering provides real-time detection and alerts for weather-related and mechanical risks, helping operators maintain grid reliability and prevent outages before they occur (slide 2).
Main benefits as printed: icing detection prevents mechanical stress and overload, reducing the risk of line failure and outages; vibration monitoring identifies risks such as galloping or aeolian vibration early, avoiding conductor damage and costly repairs; extreme weather transparency minimises outage risk, protects assets, and ensures grid stability during extreme conditions. The slide also cites proven expertise from decades of experience in power systems and grid modernization, and tailored solutions developed in close collaboration with customers' operational needs.
| Capability | Description (slide 2) |
|---|---|
| Icing detection | Combines sensor data and weather models to detect and quantify ice build-up on power lines |
| Vibration monitoring | High-frequency sensors detect abnormal vibrations caused by wind or mechanical issues |
| Extreme weather transparency | Enables rapid response to severe events such as wildfires, hurricanes, and heatwaves |
| Real-time monitoring (technical) | Multi-sensor system for continuous overhead line condition monitoring, including icing and vibration detection |
| Analytics (technical) | Automated alerts and predictive algorithms for rapid operational response and risk mitigation |
| Connectivity & integration (technical) | Integration-ready with grid control and maintenance systems; secure data transfer to dashboards for live visibility and decision support |
Advanced Inspection transforms inspections from manual, time-consuming tasks into precise, intelligence-driven processes powered by AI. It leverages aerial and ground data, AI-based analytics, and digital modelling to deliver a comprehensive, accurate, and continuously up-to-date view of the assets; this unified digital inspection layer delivers actionable insights — helping operators detect risks early, prioritize maintenance, and strengthen grid reliability (slide 3).
Main benefits as printed: reliability — comprehensive and precise inspections with consistent digital records for trend monitoring, reduced EHS exposure by limiting climbing and helicopter hover operations, and cost-efficient data access, reporting, and workflow integration; OEM expertise — in-house OEM domain know-how for all key technologies and solutions; vendor-agnostic advisory — unbiased advice through access to proprietary products and solutions of major OEMs.
Features at a glance: vegetation management (detect encroachment, simulate tree-fall scenarios, identify right-of-way obstacles such as buildings, machinery, and terrain features); AI-based inventory (automatic identification of overhead-line components including insulators, ID plates, joints, tension clamps, and marker balls); AI-based defect detection (automated detection of defects affecting towers, foundations, conductors, and structural elements); surveying / right of way (advanced GIS mapping with orthophotos up to 4 cm GSD, digital terrain and surface models, AI-powered LiDAR point-cloud classification with centimetric accuracy across X, Y, and Z).
| Capability | Description (slide 3, 'Technical information') |
|---|---|
| Data acquisition | High-fidelity helicopter, drone, and ground-based inspections using a multi-sensor system: Ultra-HD RGB cameras, 3D LiDAR scanner, and weather data; infrared (thermal) and UV/corona sensors — all co-mounted for synchronized capture and accurate 3D localization |
| Analytics | AI/deep-learning models for automated inventory, visual defect detection, thermal hotspot & corona detection, vegetation clearance & tree-fall simulation, LiDAR point-cloud classification delivering centimetric GIS accuracy |
| Data processing | High-definition multi-sensor data aligned and processed in a smart analytics platform; typical flights generate up to 100 GB per km (~160 GB per mile), ensuring precise 3D localisation and consistent trending across missions |
| Outputs & deliverables | Interactive web interface to document line findings, defects, clearance maps, and survey products (orthophotos, digital terrain/surface models); annotation of findings, maintenance-task planning, and integration of outputs into existing asset-management systems |
Each one-pager carries an experience stamp: DLR/AAR and Situational Awareness & Weather Resilience are marked 'Globally proofed', while Advanced Inspection is marked proofed 'In Europe & North America'. All three offerings are stamped version 1.0, dated February 2026, under the header 'Grid Technologies | Noedra Flow – Line digitalization | Overhead lines' (slides 1-3).
