Been done many times before, so heres a brief history;
Thorpe Marsh Power Station was a 1 Gigawatt (GW) (1000 MW) coal-fired power station near Doncaster in South Yorkshire, England.
Construction of the station began in 1959, it being built as a prototype for all the large modern power stations in the UK. It was commissioned between 1963 and 1965. It contained 2 generating sets powered by coal, and had a gas turbine set using an industrial static version of a Rolls-Royce Avon aero engine with a capacity of 14.9 MW. On 7 January 1973 four workmen died. The CEGB was put under investigation for breaches in safety provisions but they were found to have all died accidental deaths
Much of the station has been demolished and now only its six cooling towers (each 340 ft (100 m) high and 260 ft (79 m) in diameter at the base), two ash slurry hoppers, railway sidings and the station's large adjacent electricity switching station still remain. Visit;
Had no issues with security, there is a guard building on the main enternce to the site but they were only interested in protecting the demolition going on nearby. the Seco even said hi when he saw me walking round the towers. Photos taken with;
