Electric Cables: Costs

Question

To ask His Majesty's Government what assessment they have made of the relative costs of undergrounding power lines by (1) cable ploughing, and (2) open trenching.

Answer

Undergrounding is usually by open trenching with costs varying between 5-10 times those of overhead lines. These costs are from the Institution of Engineering and Technology Study, 2012. Cable ploughing is a newer method of undergrounding some types of electricity cables. The Government has not made a formal assessment of those costs. The Government regularly engages with industry to understand new opportunities and innovations.
