Introduction: This project is installing a distributed weather and conductor temperature monitoring system on a 132kV and 33kV overhead line in Cumbria and developing a Dynamic Line Rating (DLR) calculation engine within our control room management system based on the Cigré algorithm.

Objectives: The increasing pressure to connect distributed energy systems without (or with minimal) constraints and in a sustainable way is leading to a great deal of interest in the subject of DLR. Electricity North West are aiming to explore the physical loading limits of our assets rather than limit the potential connection of distributed energy sources to national planning standards.
