    Energy storage is one option to making grids more flexible. An other solution is the use of more dispatchable power plants that can change their output rapidly, for instance peaking power plants to fill in supply gaps.

    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 energy storage systems?

    It makes the most of renewable resources by releasing stored energy when demand is high or output is low instead of keeping it for use during peak production periods. Additionally, energy storage systems enable the implementation of decentralized renewable power sources, which improves energy stability and lessens dependency on fossil fuels.
