p thermal energy storage (TES) improves grid resilience by reducing peak electricity demand, providing flexibility, and enhancing the integration of intermittent renewable energy sources. Here are some key ways TES contributes to grid resilience:
Key Contributions of Thermal Energy Storage to Grid Resilience
- Peak Demand Reduction: TES systems can store thermal energy (heat or cold) during off-peak hours and release it during peak times, reducing the strain on the electricity grid. For example, in heating systems, thermal energy storage can lower the electric demand by up to three times during peak periods, alleviating the need for costly grid upgrades.
- Grid Flexibility: By shifting energy usage from peak to off-peak periods, TES helps distributors manage energy distribution more efficiently. This flexibility is particularly beneficial in managing variable supply from renewable sources like solar and wind.
- Renewable Energy Integration: TES can complement renewable energy sources by providing a buffer during periods of low solar or wind output. This ensures a stable energy supply even when renewable sources are not available.
- Reliability and Resilience: In industries like cold storage, where continuous refrigeration is crucial, TES systems enable facilities to turn off energy-intensive equipment during peak hours, reducing demand spikes and enhancing grid stability.
- Cost Savings: By reducing peak demand, TES can defer the need for costly infrastructure upgrades, offering a more economic solution to improve grid resilience.
Overall, thermal energy storage plays a critical role in enhancing grid resilience by optimizing energy usage, reducing peak demand, and facilitating the integration of renewable energy sources.
