6 FAQs about [Use valley electricity to store energy]

Why is electricity storage important?

Depending on the extent to which it is deployed, electricity storage could help the utility grid operate more efficiently, reduce the likelihood of brownouts during peak demand, and allow for more renewable resources to be built and used. Energy can be stored in a variety of ways, including: Pumped hydroelectric.

How can storage help balance electricity supply and demand?

One way to help balance fluctuations in electricity supply and demand is to store electricity during periods of relatively high production and low demand, then release it back to the electric power grid during periods of lower production or higher demand. In some cases, storage may provide economic, reliability, and environmental benefits.
