HC Deb 19 March 1970 vol 798 c184W
Mr. Chataway

asked the Minister of Technology whether he will give estimates of the percentage increase in electricity costs to the consumer in 1975, 1980, and 1985, respectively, resulting from the undergrounding from henceforth of all Central Electricity Generating Board power lines in national parks and areas of outstanding natural beauty.

Mr. Alan Williams

No: future transmission construction will depend on the growth and location of electricity demand and the siting of generating capacity. It is not possible to undertake for so far ahead the detailed predictions required to provide the estimates requested.
