View moreProblem Addressed
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, is offering a software licensing opportunity for the General Line Ampacity State Solver (GLASS) under solicitation number CW-19-22. This high-performance software platform, developed by the Idaho National Laboratory, calculates the real-time current-carrying capacity of overhead power transmission lines to mitigate grid congestion and transmission bottlenecks. The opportunity is classified under NAICS 221118 Other Electric Power Generation and PSC DA10 IT AND TELECOM - BUSINESS APPLICATION/APPLICATION DEVELOPMENT SOFTWARE AS A SERVICE. Responses are due by March 10, 2026, and the primary place of performance is Idaho Falls, ID.
The GLASS software provides a plug-and-play solution for dynamic line rating by integrating limited weather and line current data with computational fluid dynamics modeling. This method enables utilities to safely increase transmission capacity by up to 40% over conservative static limits without the need for extensive hardware sensor networks or specialized weather stations. The system calculates steady-state ampacity, transient temperature, and forecasted values, outputting results in standardized formats compatible with various utility-grade data historians and enterprise systems.
Validated against IEEE and CIGRE standards, the technology is intended for use by electric utilities, grid operators, and software vendors to improve situational awareness and support the integration of renewable energy sources. The platform serves as a software-only alternative to hardware-heavy monitoring solutions, utilizing precomputed models to extend accuracy across unmonitored spans of the transmission network.
