The UK’s National Grid is to extend the roll-out of technology to increase power line capacity across a further 585km of transmission routes.
Dynamic Line Rating (DLR) technology was first trialled by National Grid on UK transmission lines in 2022. Following its success, by 2025 it had been deployed across more than 275km of its network.
Under a new five-year contract, the technology will now be expanded across an additional 585km, potentially saving consumers up to £50m. The three firms delivering the DLR technology are US-based LineVision, Belgium-based Ampacimon and Heimdall Power from Norway.
Alice Delahunty, president of National Grid Electricity Transmission, said: “Integrating grid-enhancing technologies will deliver significant savings for consumers by reducing constraint costs and is an important part of our work to upgrade the grid to deliver a resilient, future-ready energy system.”
