Chadderton Power Station  Chadderton Power Station refers to a series of two coal-fired power stations, which were situated at Chadderton, Greater Manchester in North West England. The first power station to be constructed at Chadderton was built around 1925–1929 and was commissioned in November 1929 for the County Borough of Oldham in the Slacks Valley. The station was fueled by coal and had six cooling towers and eight chimneys. This station was still active in 1953 but at some time between 1959 and 1975 it was demolished. The principal plant at Chadderton A station comprised:   The electricity output from Chadderton A power station was:  In 1943, Oldham Corporation investigated the anticipated growth of load on their distribution area, and so a scheme was prepared to replace the existing Slacks Valley station. The preparation plan, drawn up by Kennedy & Donkin, considered other sites for the replacement but decided that the existing site at Chadderton was the most suitable, with an envisaged capacity of 120,000 kW, using four 30,000 kW turbo-alternators, installed at intervals of two at a time. However following discussion with the then Central Electricity Board, this was revised to four 50,000 kW sets, giving the station a capacity of 200,000 kW. This was revised again with the standardisation of unit sizes and operating temperatures and pressures, meaning the sets ended up each being 60,000 kW in size. Surveying of the site had indicated that the site, some in size, was of ample area for the scale of the new development. The site was partly made up of waste ground, having previously been used as an aircraft factory, and later as a cotton storage area by the Cotton Board. It also remained occupied by the low pressure Slacks Valley power station and its 132 kV transformer compound. It was found that suitable rail facilities for the new station were obtainable from the adjacent Caldervale Line. It was also found that effluent from the Oldham Corporation's Sewage Works could be used as make-up for the station's cooling towers. These factors helped in the station going ahead. The station was to be built in two phases, the first phases was granted consent in January 1950, and the second phase in September that year. Chadderton B Power Station was officially opened on 8 July 1955 by Councillor F. Kenyon, chairman of the North Western Electricity Consultative Council, and member of the North Western Electricity Board.
