Warrington power station supplied electricity to the town of Warrington, Lancashire (now Cheshire) and the surrounding area from about 1900 to 1979. The power station was initially developed by the Warrington and District Electric Light and Power Company Limited, this was taken over by Warrington Corporation, which operated the power station prior to the nationalisation of the British electricity supply industry in 1948. It was redeveloped several times to meet the increased demand for electricity.

History

Warrington and District Electric Light and Power Company Limited was registered in January 1898 to generate and supply electricity to Warrington. A Provisional Order under the Electric Lighting Acts was granted by the Board of Trade and was confirmed by Parliament through the Electric Lighting Orders Confirmation (No. 11) Act 1898 (61 & 62  Vict. c. xciv). [1] The power station was built in Howley, Warrington (53°23’08”N, 2°35’10”W). [2] [3] Equipment was added to meet the rising demand for electricity; by 1922  it had a generating capacity of 7,750 kW. [4]

From the establishment of the Warrington Corporation Tramways in 1902 the power station supplied electric current to tram system. The trams were decommissioned in 1935. [5]

Warrington power station became a selected station in the North West England and North Wales Electricity Scheme. It was part of one of three national grid rings in the northwest. Other stations on the Warrington ring were Ribble (Preston), Southport, Lister Drive (Liverpool) and Westwood (Wigan). [6]

New plant was installed and the output of the power station was uprated in 1940, 1944, 1946 and 1952. [7]

The British electricity supply industry was nationalised in 1948 under the provisions of the Electricity Act 1947 (10 & 11 Geo. 6 c. 54). [8] The Warrington electricity undertaking was abolished, ownership of Warrington power station was vested in the British Electricity Authority, and subsequently the Central Electricity Authority and the Central Electricity Generating Board (CEGB). [9] At the same time the electricity distribution and sales responsibilities of the Warrington electricity undertaking were transferred to the North Western Electricity Board (NORWEB).

Warrington power station was closed on 29 October 1979. [10]

Equipment specification

By 1923 the plant comprised boilers delivering 193,000 lb/h (24.3 kg/s) of steam to: [4]

These machines gave a total generating capacity of 7,750 kW comprising 6,000 kW of alternating current (AC) plus 1,750 kW of direct current (DC). [4]

The following electricity supplies were available to consumers:

Plant in 1940–52

In 1940 the old plant had a capacity of 12 MW; new plant with a generating capacity of 20 MW was installed. This was followed by extensions of 20 MW (1944), 20 MW (1946) and 30 MW (1952). The old plant was decommissioned in March 1949. [7]

By 1954 the plant comprised: [7]

The total generating capacity was 90 MW at 6.6 kV. [7]

Condenser cooling water was drawn from the adjacent River Mersey. [7]
