Why are electricity storage systems important?

The use of renewable energy sources like solar and wind power is often intermittent, meaning they are not always available when needed. Electricity storage systems are crucial for overcoming this issue by storing excess energy generated during peak production periods and releasing it when demand exceeds supply.

What is pumped hydro storage?

Pumped hydro storage is a major energy storage system that uses excess electricity to pump water uphill to a reservoir. When energy is needed, water flows downhill through turbines, generating electricity. This is like a giant water battery!
