Line Ratings based on precision weather forecasting

A light wind of 2 m/s adds 30% capacity to a power line by cooling it down

Hyper-local Weather

2 × more accurate wind forecasts in sheltered areas

It works right out of the box. The models are pre-calibrated based on over 30,000 weather stations globally. No additional hardware is needed.

Gridraven accurately predicts wind also in forested, hilly and built regions, making Dynamic Line Ratings possible without any additional hardware.

How it works

Wind prediction based on meter-resolution landscape images.

All of the world has been imaged from satellites and airplanes. Gridraven applies machine learning to include every tree, building and hill in our weather forecasts.

Gridraven's weather models achieve the required accuracy for boosting grid capacity with no hardware at all.
Power lines are limited by overheating so that when it's cold or windy the same line can carry up to 2× more power.

Calculate ratings based on IEEE and CIGRE standards

Boost capacity day-ahead

Increase the available capacity for energy markets.

Ambient Adjusted Ratings

Account with solar irradiation and ambient temperature for accurate ratings up to 10 days ahead.

Dynamic Line Ratings

Maximize grid capacity by accounting with wind cooling up to 72 hours ahead.

Works anywhere in the world

Scalable to your full network

Gridraven already covers every span of your every line.

Gridraven is working with Elering, the Estonian national grid, on a full-network Dynamic Line Ratings pilot covering 15,000 spans of 3500 miles of transmission and distribution lines.

Accurate

Wind forecasts with 2× higher accuracy in sheltered areas

Forecast ratings with precision in all geographies and optimize transmission capacity with span-level precision. By incorporating sub-meter remote scanning data from airborne LiDAR and satellites, Gridraven Claw forecasts weather conditions close to the ground in all types of terrain.

Reliable

Forecasts ratings with 98% or 99% confidence intervals

Determine the conditions in all spans under all weather conditions. Our weather models learn the patterns of errors in weather forecasts based on millions of measurements and provide probability estimates for every forecast. Ambient ratings are forecasted up to 10 days ahead. Dynamic Line Ratings are provided up to 72 hours ahead.

Scaleable

Globally applicable with no hardware needed

Implement Dynamic Line Ratings across entire power grids. Zero upfront cost and no hardware investment needed to cover eery span in your network. Straightforward API integration with your SCADA/EMS.
