Full description
Trueman, M., 1994 - 1998, Electric Power Generation (Report - non-specific). SDV335661.
Morwellham Power Station built in 1934 by the West Devon Mining & Power Co. The scheme took water from the river Tavy via the Tavistock canal, and discharged into the river Tamar. It remains operational. Historically important site in terms of the twentieth-century development of England's hydro-electric resource and as a working example. Such schemes were, and are, rare in England, although it is from an era that post-dates Britains technologically innovative lead.

The hydro-electric power station at Morwellham was built in 1932 using water brought along the old canal from the River Tavy at Abbey Weir to a million gallon storage reservoir 250 feet above Morwellham Quay. The water is taken down the cliff through a 3 feet diameter pipeline into two turbines. In December 1979 the River Tamar reached an exceptional flood level inundating the station floor to a depth of 2 feet.
Chitty, G., 2000, Electric Power Generation, Step 4 Report, Monument Protection Programme, Site 3 (Report - non-specific). SDV335660.
A working hydro-electric station of 1930s, utilising stored river water and the canal system, with a well preserved layout. Originally operated privately to power local copper mining. Historically important as a representative of inter-war hydro schemes, which were never numerous, and this is a relatively unaltered example. One of four extant stations of the West Deven Electric Supply Company.
