Harrogate power station. Harrogate power station supplied electricity to the town of Harrogate and the surrounding area from 1897 to 1960. The power station was built by the Harrogate Corporation which operated it until the nationalisation of the British electricity supply industry in 1948.

History 
The Harrogate Corporation applied for a Provisional Order under the Electric Lighting Acts  to generate and supply electricity to the town of Harrogate. An Order was granted by the Board of Trade and was confirmed by Parliament through the Electric Lighting Orders Confirmation (No. 1) Act 1891 (54 & 55 Vict. c. xlix).

The power station was built north of the town off Ripon Road Harrogate (54°00’03”N 01°33’17”W); it began to supply electricity on 14 April 1897. The site was adjacent to the Oak Beck which provided make-up water to the station's spray cooling pond.

The Central Electricity Board built the first stages of the National Grid between 1927 and 1933. Harrogate power station were connected to the 132 kV electricity grid. In 1935 Ripon ceded its electricity supply rights to the Harrogate electricity undertaking.

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

Following nationalisation Harrogate power station became part of the Harrogate electricity supply district, covering an area of 192,084 acres (77,734 ha).

Harrogate power station was closed in 1960.
