HC Deb 21 July 1976 vol 915 c492W
Mr. Skeet

asked the Secretary of State fir Energy if he will indicate the percentage loss of electricity through transmission over variable distances.

Mr. Eadie

The percentage loss in electricity transmission depends on a number of factors including the operating voltage of the line, the extent to which it is loaded, the ambient temperature and whether the line is overhead or underground. The energy loss on a main overhead transmission line in the United Kingdom would be in the region of 0.01 to 0.03 per cent. for each route mile of length.
