The power plant is the largest of its kind in England and Wales and has generated renewable energy since 1962.

The environment was taken into consideration when designing it’s scheme in the 1950’s: The award winning Felin Newydd Falls in Cwm Rheidol were designed to blend in with the surrounding countryside, and many of the scheme’s buildings are clad with local stone.

The plant covers an area of 162 square kilometres and is made up of an interconnected group of reservoirs, dams, pipelines, aqueducts and power stations. Their highest peak is situated at 750 meters above sea level in the Plynlimon mountain range.

A series of aqueducts collects the water and channels it into the Nant-Y-Moch reservoir. From there, water flows to a power station at Dinas featuring a 13 MW generator.

Dinas' additional reservoir then supplies water to the largest power station at Cwm Rheidol with two 20.5 MW generators.

At Cwm Rheidol, a further reservoir has been created to avoid large variations in the flow of water down river towards Aberystwyth.

This reservoir collects the water that flows through the power station and releases it slowly through a 1 MW generator at Cwm Rheidol Dam.

The control room at the Rheidol hydropower plant also monitors the operations of Statkraft’s onshore wind farms in the UK.
