The most common technologies used in energy storage systems for peak shaving include:
- Battery Energy Storage Systems (BESS): These systems are highly effective for peak shaving due to their ability to store energy during off-peak hours and release it during peak demand periods. BESS can quickly respond to changes in energy needs and are widely used in various industries, including manufacturing, commercial buildings, and data centers.
- On-site Generation with Energy Storage: This approach combines on-site power generation sources like solar panels or wind turbines with energy storage. The excess energy generated during peak production hours can be stored for later use, reducing reliance on the grid during peak demand periods.
- Bidirectional Electric Vehicles: Vehicles with bidirectional charging capabilities can also act as energy storage systems by storing electricity when not in use and supplying it back to the grid or local loads during peak demand periods.
- Other Energy Storage Options: While less common for peak shaving than batteries, other technologies like hydrogen storage via electrolysis and thermal storage are emerging for specific applications, especially industrial and large-scale uses.
