National Grid has completed the installation of dynamic line rating (DLR) technology from LineVision across 275 kilometres of overhead power lines, in a move aimed at increasing grid efficiency, reducing costs, and enabling greater integration of renewable energy.
The technology, now operational on circuits between Penwortham and Daines, and Norton to Thornton, uses sensors to monitor real-time environmental and line conditions. This allows operators to safely increase transmission capacity beyond traditional static limits.
“This will boost the capacity of our existing infrastructure and help increase the network’s capacity for renewable power,” said Corin Ireland, SO:TO optimisation engineer at National Grid.
The deployment is expected to unlock enough grid capacity to supply renewable electricity to approximately 75,000 homes and generate potential savings of up to £20 million annually by reducing the need for more costly network reinforcements.
Hudson Gilmer, chief executive of LineVision, said the project would “rapidly deliver real benefits to customers” while also improving grid reliability.
The rollout forms part of National Grid’s broader investment strategy to upgrade and modernise the electricity transmission system under The Great Grid Upgrade, a key initiative supporting the UK’s transition to a net-zero energy system.
