History

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]

Power station owners

The owners and operators of the power station over its operational life were: Dolgellau Urban District Council (1935–48), British Electricity Authority](1948–55), Central Electricity Authority (1955–57), Central Electricity Generating Board (1958–70). [3]
