 Following the Second World War the demand for electricity increased in the United Kingdom . In North East England , this led to the construction of two new power stations at Stella , along with the expansion of stations at Dunston and Billingham , to meet the demand for power quickly . At Blyth , a larger and more efficient plant was planned , consisting of six 100 megawatts ( MW ) generating units . This increased to six 120 MW units , before increasing again in the final proposal for an A station consisting of four 120 MW units and a B station consisting of two 275 MW units and two 350 MW units . This gave the A and B stations generating capacities of 480 MW and 1 @,@ 250 MW respectively . The Blyth Power Stations were to be an experiment , using a variety of generating set sizes at a time when engineers were trying to standardise power station plant and layout . Blyth was the first in the UK to use generating sets larger than the then standard 30 MW and 60 MW . The station 's location was chosen because of its position within the super grid , rather than to be near a load centre .
