High-voltage transmission line capacity is strongly influenced by weather conditions such as temperature, wind, and solar radiation. Traditionally, operators rely on Static Line Rating, which often leaves a significant portion of the grid underutilized. Dynamic Line Rating (DLR) leverages real-time weather data to determine the actual capacity of transmission lines. 

The Belgian Royal Meteorological Institute (RMI), Elia, PropheSea, and GeoSphere Austria are currently developing a next-generation pilot service for Dynamic Line Rating, under a contract with ECMWF as part of the European Commission’s Destination Earth initiative. Their objective is to introduce an advanced level of granularity in weather forecasting, combining on-demand simulations of the Extremes Digital Twin with DLR technology. As such, they strive to optimize the use of existing grid infrastructure, potentially reducing costly investments such as deploying additional sensors on overhead lines and reinforcing the grid, by maximizing the lines’ rated capacity.

The webinar is hosted by PropheSea, RMI, Elia and GeoSphere Austria.

Program: 

• Explain the fundamentals of DLR – Understand why DLR matters, its advantages, and its contribution to the energy transition.
• Share insights on their methodology – Discover how high-resolution, on-demand weather forecasts are combined with DLR technology in this pilot service.
• Present preliminary results – Get a first look at their findings and learn about the project’s objectives.
• Engage in a Q&A session – Discuss your questions, provide feedback, and explore how the pilot service could benefit your operations.

Learn more about the project at the 4th Dynamic Line Rating (DLR) and Grid Enhancing Technologies (GETs) 2025 in October in Amsterdam! 

About Destination Earth and ECMWF 

Destination Earth is a European Union-funded initiative launched in 2022 aimed at creating a digital replica of the Earth system by 2030. It is jointly implemented under the leadership of Directorate-General Communications Networks, Content and Technology (DG CNECT) by three entrusted entities ECMWF (responsible for the Digital Twins and Digital Twin Engine), ESA (responsible for the Core Service Platform), and EUMETSAT (responsible for the Data Lake).”

This activity is supported by ECMWF for Destination Earth.
