LineVision, a U.S.-based provider of non-contact overhead power line monitoring systems, today announced the continued deployment of its Dynamic Line Ratings (DLR) technology on National Grid’s electricity transmission network in the United Kingdom (U.K.). This effort is aimed at unlocking additional capacity on existing transmission corridors to speed the integration of secure, affordable power sources while reducing costs for energy consumers.
LineVision’s advanced sensors have been installed on key circuits along some of the most constrained north-south transmission lines in the U.K. The project spans more than 170 miles of overhead conductors across multiple transmission lines.
This deployment is expected to greatly increase the capacity of these lines to transmit electricity, potentially powering an additional 75,000 homes annually – and could deliver annual consumer savings of $26 million by alleviating costly congestion. Early results show LineVision’s DLR has already increased capacity on these lines by over 20%.
This expansion builds on successful projects completed on both sides of the Atlantic. In the U.S., National Grid has implemented LineVision’s solutions on networks in New York and Massachusetts, where DLR has proven effective in increasing grid reliability.
“We’re proud to support National Grid’s leadership in deploying grid-enhancing technologies that boost capacity, reduce congestion, and rapidly deliver real benefits to customers,” said LineVision CEO Hudson Gilmer. “This technology unlocks additional capacity on existing lines, helping National Grid meet the challenge of surging load growth, strengthen grid reliability and honor their commitment to affordability.”
“Integrating grid-enhancing technologies such as LineVision’s is a crucial part of National Grid’s work to increase the capacity of our network to meet increased demand,” said Mark Lissimore, Director of Infrastructure Delivery at National Grid Electricity. “Innovative projects such as this will boost the capacity of our existing infrastructure and help increase the network’s capacity for renewable power, delivering lower costs for consumers whilst continuing to maintain world-class reliability.”
LineVision’s DLR system utilizes non-contact sensors to continuously monitor power line conditions and environmental factors. This data is used to calculate a real-time “dynamic line rating,” reflecting the actual capacity of the line under prevailing weather and loading conditions. Unlike static ratings – which are based on conservative, fixed assumptions – dynamic ratings safely and reliably unlock additional capacity by increasing situational awareness of line capacity in real time.
LineVision is proud to be part of the National Grid Partners investment portfolio, working to modernize transmission infrastructure globally.

About National Grid in the UK
National Grid sits at the heart of Britain’s energy system. The individual companies in our group run the networks and infrastructure that connect millions of people to the electricity they use every day.
Our regulated businesses own and develop the high voltage electricity transmission network in England and Wales, and the electricity distribution network in the Midlands, South West England and South Wales. Operating separately from these core regulated units, National Grid Ventures (NGV) focusses on competitive markets, investing in energy projects, technologies and partnerships such as electricity interconnectors.
We bring energy to life, with an ambition to serve our customers well, support the communities in which we operate, and make possible a clean, affordable and resilient future energy network.
Facts about our networks in England and Wales:
- Our transmission network takes electricity generated from different power sources and carries it at high voltage via our 7,000km of overhead line, 700km of underground cable and over 300 substations.
- Our distribution network delivers electricity at lower voltage from our transmission network to where it’s needed in the regions we serve, via 60,000 miles of overhead line and 83,900 miles of underground cable.
