In 1949, the British Electricity Authority decided to upgrade the grid by adding 275 kV links. At its inception in 1950, the 275 kV Transmission System was designed to form part of a national supply system, with an anticipated total demand of 30,000 MW by 1970. This predicted demand was already exceeded by 1960.
