Hydro-electric power stations are an important source of renewable energy.
In this model you will learn how a hydro-electric power station operates and why it forms a vital part of an energy distribution grid
Hydro-electric power stations convert gravitational potential energy stored by the water in the dam to electrical energy that can be transmitted around the country to homes and factories.
Press the button to view the inside of the power station.
Water is allowed to flow through turbines in the dam. The turbines are attached to generators that produce electricity ready for transmission.
Hydro-electric power stations are especially important as they can be used for energy storage.
During periods of peak supply, when electricity is cheap and available, water can be pumped back into the dam.
When demand rises, such as in the evening or during a special event, the hydro-electric plant can be activated and the stored energy converted back into electricity.
A major sports event is on television and a nearby coal power station that supplies power to this region cannot keep up with the demand.
Turn on the switch to connect the Hydro-electric power station to the grid and restore power.
In real life, the distribution company monitors supply and demand in real-time to adjust the generating capacity.
The hydro-electric power station would be started automatically without any interruption in power.
