- The construction of approximately 25km of new 132kV Overhead Line to replace the existing line linking Lewis and Harris
- The construction of a new Gas Insulated Switching Station near Balallan, to facilitate the connection of the Muaitheabhal Wind Farm onto the electricity transmission network
- The removal of the existing 132kV Overhead Line between Balallan and Stornoway Grid Supply Point
- Connections of the Overhead Line at Balallan, Stornoway Grid Supply Point and the new Arnish Substation
