The current carrying capacity of overhead transmission, and distribution (T+D) lines has become a key constraint for global electrification. Global electricity demand is due to increase 75-150% 2022-2050 (IEA,2022). The current mechanisms to increase T+D capacity are based on large infrastructure projects such as reconductoring, taking 3-7 years, costing £300k/km or building new lines (7-10 years, £1mn+/km). More cost-effective ways to increase transmission and distribution capacity are required. This project involves the development of an automated coating systems for overhead lines, configured to deploy a specialised photonic coating which increases the capacity of overhead lines. This will permit a transition from a T+D uprating paradigm of heavy infrastructure projects to one of advanced mechatronics and functional coatings.

The project aims to demonstrate discontinuous cost savings in upgrading transmission and distribution capacity via the application of capacity-enhancing coatings to overhead lines.
