Live ratings, ready to stream to any line, worldwide.
Static ratings assume the worst weather all year. LineClarity gives each line its real, weather-driven rating — typically +15–35% more capacity, live, with an automatic fail-safe to your static rating.
In May 2026 a single PJM line racked up about $150M of congestion in 72 hours during a heatwave — software dynamic ratings could have saved roughly $100M in three days. PJM congestion hit $3.2B in 2025 and is climbing with data-center load. The headroom is real — LineClarity computes it from live weather, in software.
What you see below is a live snapshot. In service, LineClarity delivers your line's rating as a continuous real-time feed — recalculated as the weather changes and pulled by your systems whenever they need the current limit.
Built on the IEEE-738 standard: live ambient temperature, wind and solar become each line's real, weather-driven capacity — updated hour by hour.
LineClarity publishes a safe operating limit that captures the headroom your static rating leaves on the table, while always staying within the line's thermal limits. Validated against IEEE-738.
You pull a numbers-only rating feed. If it's ever late, missing or out of range, your system falls back to the static rating. It can only add capacity — never make the line less safe than today.
FERC-881 makes weather-based ratings mandatory — LineClarity delivers a compliant, live real-time feed and the capacity your static ratings hide. And it's pure software: no sensors, no trucks, no hardware. Where sensor systems run into the hundreds of thousands per line to install, LineClarity covers every line for a fraction — stood up in days, pull-only, fail-safe, on-prem if you need it.
