[1] In 1964/65 Rheidol Power Station was awarded the Christopher Hinton trophy in recognition of good housekeeping.

The plant covers a total area of 162 square kilometres (63 sq mi) and is made up of an interconnected group of reservoirs, dams, pipelines, aqueducts, and power stations.

Water flows from this reservoir to a power station at Dinas where it drives a 13 MW generator.

Dinas reservoir supplies water to the largest power station at Cwm Rheidol where there are two 20.5 MW generators.

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