Dolgelley power station
From Wikipedia, the free encyclopedia
Dolgelley or Dolgellau power station was a combined diesel and hydroelectric generating station. It provided electricity to the town of Dolgellau, Gwynedd, Wales and the surrounding district from 1936 until the 1960s.
Dolgellau Urban District Council constructed a combined diesel engine and water-turbine electricity generating plant at Frongoch Dolgellau.[1] In 1936–7 the Electricity Commissioners had authorised the Council to obtain a loan of £4,979 for building work, the purchase of plant, the installation of mains, and the provision of customers’ meters.[2] Upon the nationalisation of the British electricity supply industry in 1948 the Dolgellau power station was vested in the British Electricity Authority.[3] The power station was decommissioned in the 1960s.[4]
