First Hydro Company operates various hydroelectric power stations in Britain. This includes the management and operation of the pumped storage plants at Dinorwig and Ffestiniog in the Snowdonia region of Wales. Dinorwig are former slate quarries and so the water scheme was considered a subsequent use of an landscape already heavily alterated by human. Ffestiniog Power Station was the UK's first major pumped storage power facility commissioned in 1963.

The Visitor Center offers exhibits on the power scheme, the pumped storage, the historic mining and much more. It is also the start for guided tours to the power station and the miles of underground tunnels. Currently [2020] the center is closed and there are no tours this year. The will be held again after the construction of the new Visitor Center is completed.
