How to turn water into electricity in less than 10 minutes

The Dinorwig Power Station is the United Kingdom’s biggest pump-storage facility.

The plant uses simple science to generate backup power for the grid.

Water from its top lake rushes downhill via large tubes into massive turbines. This creates backup electricity for the grid. The hydroelectric power plant needs about 10 minutes of time to start the process to create backup power.

For every 3 units of electricity it generates, it uses 4 units to pump the water back up to the top of the mountain.

This power station was constructed deep inside the mountain Elidir Fawr… preserving the natural beauty of Snowdonia National Park.
