Why is energy storage important?
Much like refrigerators enabled food to be stored for days or weeks so it didn't have to be consumed immediately or thrown away, energy storage lets individuals and communities access electricity when they need it most—like during outages, or when the sun isn't shining.
Why do power plants need energy storage systems?
For one, they can make power grids more flexible. In times of low demand, excess electricity generated in power plants can be routed to energy storage systems. When demand rises—during a heat wave, for example—stored energy can be deployed to avoid straining the grid. Stored energy can also provide backup power.
Why do we need electricity storage?
More broadly, storage can provide electricity in response to changes or drops in electricity, provide electricity frequency and voltage regulation, and defer or avoid the need for costly investments in transmission and distribution to reduce congestion.
