Pumped storage power plants are all-rounders in the energy industry. On one hand, they can store energy. On the other hand, they are connected to the grid as electricity producers within a few seconds. In this way, they help to cover energy requirements when other supply capacities are not sufficient and provide important emergency reserves in the event of power plant outages.
What pumped storage power plants can do
- They store large quantities of electricity like a gigantic battery.
- They deliver electricity to the market on demand.
- They compensate for fluctuations in the power grid.
- They compensate for fluctuations in the supply of sun or wind.
- They are black-start ready – in other words: They quickly rebuild the power grid in emergencies.
