What we used to know as Blyth Power Station was actually two generating stations built alongside each other. Blyth A first produced electricity in 1958 using four 120MW generating units with Blyth B being built four years later with two 275MW units and two 350MW units. The engineering was done by Merz & McLellan and the stations were built by the Cleveland Bridge Company.
By September 1966 the site was fully operational with a generating capability of 1,730MW making it briefly the biggest in the UK before Ferrybridge C Power Station came into operation later in the year.
The A Station's two chimneys stood at a height of 140 metres whilst Station B's were higher at 170 metres and, for over forty years, the four chimneys were a very distinct landmark and could be seen from many parts of Northumberland before being demolished on 7 December 2003, the power station having closed in 2001.
The site is still derelict although in recent years there have been, as yet, unfulfilled plans for a new coal-fired power station or a site for wind turbine construction.
A little bit of "movie trivia": the site was used as a location for the film "Alien 3".
Congratulations to The Hills on their FTF.
