Energy storage improves grid resilience during peak demand periods primarily by acting as a flexible energy buffer that “time-shifts” electricity supply. It stores surplus energy generated during low-demand times—often from renewable sources like solar and wind—and discharges it when demand peaks, thereby balancing supply and demand more effectively.
Key ways energy storage enhances grid resilience in peak periods include:
- Reducing reliance on peaker plants: Peaker plants, which operate only during peak demand, are costly and less efficient. Energy storage can supply power during these times, decreasing the need for such plants and reducing operational costs and emissions.
- Managing peak capacity: Battery energy storage systems (BESS) can store energy when the grid is under less stress and release it during peak usage, which helps maintain grid stability even during extreme weather or high demand events.
- Supporting renewable integration: Since renewables are variable and not always generating when needed, energy storage ensures that renewable energy can be dispatched during peak demand, enabling a cleaner and more reliable energy mix.
- Enhancing grid stability and reducing costs: By smoothing out fluctuations in supply and demand, energy storage reduces grid strain, lowers the risk of outages, and leads to cost savings for utilities and consumers.
Overall, energy storage systems are foundational to a resilient grid capable of meeting growing and variable demand while integrating clean energy sources efficiently.
