It was located in the Layerthorpe area of the city,[2] to the east of the city centre.
It was built by York Corporation in the 1890s, opened in February 1900[3] and closed on 25 October 1976.[4]
History
In 1923 the station was supplying 3-phase AC at 400 and 230 V; DC at 460 and 230 V; and DC for traction at 500 V.[5] The steam turbine driven AC generators comprised two 1,250 kW and two 3,500 kW machines. DC current was produced by two 500 kW oil-driven machines. Electricity supplies were supplemented by a water powered generating station near Linton-on-Ouse (Linton Lock Hydro), which was commissioned in 1923 and comprised a 250 kW and a 500 kW generator. In 1923 the facilities at York generated 15.128 GWh of electricity. The sales of electricity produced a surplus of revenue over expenses of £26,938 for the Corporation.[5]
The steam plant at Foss Island were chain grate stoker boilers capable of delivering 400,000 lb/h (50.4 kg/s) of steam at 400 psi (27.6 bar) and 399/427°C.[6] The generating capacity of the station was 40 MW. Steam condensing and cooling was by river water and a single concrete cooling tower. In the year ending 31 March 1972 the station delivered 54.772 GWh of electricity, its load factor (the average load as a percent of maximum output capacity) was 16.4 percent.[6]
The electricity output from the station, in GWh, was as follows.[7][8][9]

The buildings were demolished around 1980 and the transmission line which ran from the power station to a substation at Tang Hall Lane was dismantled at around the same time.
