Transmission bottlenecks: Utilities face congestion and efficiency losses due to static line ratings that underestimate real capacity.
High costs of monitoring: Installing weather stations or hardware sensors along every line span is prohibitively expensive.
Integration challenges: Many dynamic line rating (DLR) solutions require proprietary hardware or external portals, complicating adoption.
Solution
GLASS provides a software-only, plug-and-play solution that:
Uses limited real-world weather and current data inputs.
Applies precomputed CFD models to extend accuracy across unmonitored spans.
Calculates real-time and forecasted ampacity values to maximize grid utilization.
Outputs standardized text files easily integrated with existing utility systems.
Key Advantages
Higher capacity utilization: Can enable line ratings up to 40% above conservative static limits.
Lower infrastructure costs: Reduces need for dense weather station deployment.
Seamless integration: Simple, agnostic input/output formats support adoption without system overhauls.
Proven reliability: Validated through years of testing and alignment with IEEE and CIGRE standards.
Flexible deployment: Works with any utility-grade data historian or enterprise system.
Market Applications
Electric utilities: Enhance grid flexibility, reduce congestion losses, and safely integrate renewable energy.
Grid operators: Improve real-time situational awareness and operational decision-making.
Software vendors: Incorporate GLASS as a dynamic line rating module within existing platforms (e.g., OSIsoft PI).
Renewable integration: Support greater use of wind energy by capturing wind cooling effects on lines.
The Department of Energy, through the Battelle Energy Alliance–DOE CNTR, has issued special notice CW-19-22 regarding a licensing opportunity for the General Line Ampacity State Solver (GLASS) software. Developed by Idaho National Laboratory, GLASS is a high-performance platform designed to optimize power transmission capacity in real time by calculating the current-carrying capacity of overhead lines. This opportunity is classified under NAICS 221118, Other Electric Power Generation, and PSC DA10, IT and Telecom - Business Application/Application Development Software as a Service. The software provides a plug-and-play solution for electric utilities and grid operators, utilizing computational fluid dynamics and minimal data inputs to increase line ratings up to 40% above conservative static limits.
The GLASS platform facilitates the integration of renewable energy and reduces grid congestion by providing accurate thermal state insights without the need for dense hardware sensor networks. The system is validated against IEEE and CIGRE industry standards and outputs results in standardized formats compatible with various utility enterprise systems and data historians. Performance of the technology involves extrapolating weather and line current data across unmonitored spans to support operational decision-making. Responses for this Idaho Falls-based licensing opportunity are due to Javier Martinez by March 10, 2026.
