Maentwrog Dam was built in the 1920s to provide a source of hydroelectric power. Later in 1965 the lake also became a source of cooling water for the nuclear power station.

Trawsfynydd nuclear power station was the only inland nuclear power plant in the UK. It was able to be situated here because of the large lake that provided sufficient cooling water to the reactors. The power station switched on in 1965 and closed at the end of its safe life in 1991. The planned decommissioning was expected to take about 100 years but in 2021 the Welsh government started to explore plans to install a smaller reactor and reinstate the power station to help Wales reach zero carbon electricity production.
