§ Mr. SteinbergTo ask the Secretary of State for Energy if he will estimate the cost of placing electricity cables underground compared with pylons; and what measures he is taking to encourage more electricity cables to be laid below ground.
§ Mr. Heathcoat-AmoryThe cost of placing electricity cables underground compared with overhead lines is a matter for the National Grid Company and the regional electricity companies, but for high voltage lines is approximately between nine and 10 times more expensive. All new overhead lines require a consent under section 37 of the Electricity Act 1989 and, in considering applications, the Secretary of State must have regard to the preservation of amenity.
