Water tail race from Cwm Dyli hydro electric power turbine hall after generation of electricity Snowdonia
Hydroelectric green energy has been generated at Cwm Dyli since 1906 to supply power to then prosperous slate industry. The hydro site is historic due to electricity produced there powering the first ever transatlantic transmission station set up by Marconi in 1912 near village of Waenfawr, Carnarfon. The power house was rebuilt in 1990 with a Francis turbine capable of producing megawatts of electricity. Water comes from Llyn Llydaw high above the site just beneath Mount Snowdon where very high rainfall averages more than 400 centimetres a year (or 13 feet). The water passes through an intake grid chamber and onto the turbine generator. The turbine is controlled from a computerised panel and the amount of electricity generated is dependant on the amount and flow of water from the pipe. A tailrace returns the water after it has passed through the turbine to the main stream. The generation of this clean electricity will help prevent an annual release of many tonnes of the main greenhouse gas, carbon dioxide, which is a major contibutor to global warming and climate change.
