Radyr Weir hydro scheme commissioned.

The Radyr Weir hydro scheme located on the River Taff, South Wales, is now fully completed and operational. The 2 x 200 kW Archimedes screw turbines, with their combined capacity of 400 kW, were commissioned in December 2015. The hydropower scheme is located to one side of Radyr Weir and makes use of 3.5m head and a mean flow of around 22 cubic metres per second. This is a relatively large scheme and it is estimated to produce an annual energy yield of 1.8 million kWh (equivalent to well over 400 UK homes) and an annual CO2 saving of around 785 tonnes. Renewables First produced the detailed designs and specification of the hydropower scheme for the main contractor, Dawnus Construction, acting on behalf of Cardiff City Council.

Back in Autumn of 2015, the large Archimedes screws were lifted into position using large cranes. The photographs above provide an aerial (drones eye) view of this procedure taking place. Each one of the Archimedes screws has a diameter of 3.5 metres and are 10 metres long. The pictures below show a ground level view of the site today. The image on the left shows the water intake screen close to the location of the Archimedes screws. The image on the right shows the view down the water intake toward the turbine house.

The picture below is taken from the downstream end of the hydro scheme. Just visible beneath the protective screens are the tips of the Archimedes screws. To the left of those is the new fish pass, which itself runs alongside the original fish pass on the weir.
