Utility-scale batteries can provide a variety of ancillary services beyond frequency response, which is crucial for maintaining grid stability. Here are some additional services they offer:
- Ramping and Spinning Reserve: These services provide immediate backup power during sudden changes in generation or demand, maintaining system stability by rapidly increasing or decreasing power output.
- Voltage Support: Utility-scale batteries can help maintain stable voltage levels in the grid by adjusting their power output in real-time, which is essential for preventing voltage fluctuations that could disrupt grid operations.
- Transmission and Distribution (T&D) Upgrade Deferral: By reducing line losses and delivering power locally, energy storage systems can improve efficiency and reduce the need for costly upgrades, optimizing existing grid resources.
- Reserve Capacity: Batteries provide reserve capacity for grid emergencies, acting as a buffer during periods of high demand or when power generation drops unexpectedly.
- Curtailment Mitigation: Utility-scale batteries can store excess energy from renewable sources during low-demand periods and release it during peak demand, reducing the need to curtail renewable energy production.
These services not only enhance grid stability and reliability but also support the integration of renewable energy sources into the grid.
