Great Britain's largest battery is a lake

In Wales, in the town of Llanberis, the Dinorwig power station, also called Electric Mountain, is a pumped-storage hydroelectric power station.
In this video by Tom Scott (November 5, 2018), Engie explains how this rather surprising power station works.
In short, gravity does the work. At the top of the mountain there is a reservoir, at the bottom another one, and between the two, the hydroelectric power station is installed in caverns inside the mountain. Water moves from one reservoir to the other, triggering a turbine that converts this energy into electricity and then exports it to the national electricity supply system.
During the night, the system is reversed, the turbine becomes a pump, the generator becomes a motor, and the water is sent back to the upper reservoir. The idea is that during the day the power station helps meet electricity demand, and at night, when the population consumes less electricity, the station uses the electrical surplus to prepare for the next day.
To sum up, the plant produces energy during the day and consumes energy at night, which will be converted back the following day. The water moves between the two reservoirs to use gravity in one direction in order to produce electricity.
According to the official website electricmountain.co.uk, today, in June 2019, Electric Mountain is closed for renovation and partial demolition.
