A Carillion and Eltel Networks joint venture has won a £38m National Grid contract.
The JV will design, procure and build a 400 kV double circuit overhead line which will run between National Grid substations in Canterbury and Richmond.
Fittings and conductors will be installed along the 20 km route as well as 60 new steel lattice towers.
The existing 132 kV overhead line running between Canterbury South and Richborough substations will be dismantled and removed.
Temporary and permanent diversions of existing overhead lines will be put in place, including temporary access roads, bridge structures, highway works, construction compounds, protective scaffold structures and ecological mitigation works.
The project will be the first overhead line construction under the new Development Consent Order planning requirements, which place greater focus managing environmental and local community impact.
Design and planning work will start immediately, with work on site due to start in summer 2017. Work is expected to be completed in 2020.
