Sensorless Dynamic Line Ratings
Cover all voltage levels from 30 kV to 765 kV
With enough transmission capacity we would always enjoy the lowest cost power generation. Data centres, industry and new power plants could connect to the grid without having to wait ten years for grid upgrades. Zero marginal cost solar and wind would not be wasted due to congestion. Power prices are high when there is not enough grid capacity.
The slow pace of building new power lines is the biggest obstacle on the path towards energy abundance. But the existing grid is not yet used to its maximum potential.
Your existing grid can handle 30% more power with GridRaven's fully sensorless Dynamic Line Ratings. We are ready to help you do so right away. Fast-track the connection of new generation, reduce curtailment, sell more power and bring down the cost of energy.
Grids are under increasing stress due to the growing demand for power around the world.
Grids are under increasing stress due to the growing demand for power around the world.
The best resources for solar and wind are often located far away from centres of demand with weak existing grids. Transporting this zero marginal cost power to consumers requires a massive grid build-out.
The acceleration in the pace of building the grid is unprecedented. The quickest way to add capacity is to maximize existing lines.
The grid already cannot handle new connection requests from industry, data centres, batteries, EV chargers or solar and wind generators. The lack of transmission capacity is now the biggest obstacle to affordable power prices.
High-voltage transmission lines are extremely sensitive to the weather and especially wind. A light wind doubles the capacity of an overhead line. Grid capacity can safely be increased by one third by properly accounting with the conditions along power lines.
Fully sensorless Dynamic Line Ratings
Account with actual temperature and clearance limits.
Account with actual temperature and clearance limits.
Reduce line ratings in hot, windless hours to ensure safety
Traditional static ratings are overly generous around 3% of the time, in hot, windless hours. Accurate ratings help reduce the risk of damage to the grid.
Determine clearance from the ground and objects in each span
Possible clearance violations reduce the maximum operating temperature of a span. GridRaven Claw ensures clearance limits are maintained.
Ratings are calculated based on IEEE and CIGRE standards
Line rating calculation methods have known limitations. GridRaven relies on and improves the existing methods.
Downscaling Numerical Weather Predictions based on Digital Elevation Models from satellite and LiDAR scans.

Wind forecasts close to the ground in sheltered areas
By accounting with the detailed landscape around every span of every power line, GridRaven Claw can cover power lines at any voltage level in all types of terrain.
Forecast grid capacity in sufficient time for operational planning
Ambient temperature and solar irradiation can be forecasted up to 10 days ahead. Wind speed and direction can be predicted at least 72 hours ahead.
Wind forecasts with 50% increase in accuracy over the best NWP
Our weather models are trained on tens of thousands of weather stations. Our predictions are 50% more accurate for wind speed prediction than available weather forecasts.
GridRaven Claw is available globally, with hyper-local precision.

Forecast ratings with precision in all geographies
Optimize transmission capacity with span-level precision at all voltage levels, from urban areas to challenging terrains such as hills and forests.
Determine the conditions in all spans under all weather conditions
Ensure that operators can reliably assess line conditions under any weather scenario, enhancing both grid capacity and safety
Globally applicable with no hardware needed
Implement Dynamic Line Ratings across entire power grids, regardless of location or size. Straightforward API integration with your SCADA/EMS
Your grid is probably not operated safely during hot, windless hours, especially on parts of your network that are sheltered from the wind by trees, buildings or hills. Such lines are at risk of overheating and can become damaged or even spark wildfires.
GridRaven ensures the actual limits of your grid are always maintained, in every section of every line. Most of the time you'll gain additional capacity, but sometimes capacity should be reduced. We ensure there are no safety violations anywhere in your network. We give you peace of mind.

Meter-scale precision in weather modelling is needed to increase the capacity of every power line in the network, including at medium voltage levels such as 30 kV. GridRaven applies machine learning to achieve the required accuracy.
