The most effective types of energy storage systems for peak shaving are primarily battery energy storage systems (BESS). These systems are highly efficient due to their ability to charge during off-peak hours or when renewable energy is available and discharge during peak demand periods, thereby reducing reliance on the grid and minimizing demand charges. Here are some key points about these systems:
Battery Energy Storage Systems (BESS)
- Flexibility and Efficiency: BESS can be integrated with renewable energy sources like solar or wind power, allowing them to store excess energy generated during non-peak hours.
- Dispatchability: They can be strategically controlled to charge and discharge at optimal times, making them ideal for peak shaving.
- Cost Savings: By reducing peak demand, businesses can avoid high-demand charges, leading to significant cost savings over time.
- Reliability: BESS provide backup power and improve power quality, especially in critical infrastructure like hospitals and data centers.
Other Emerging Technologies
While batteries are the most commonly used technology for peak shaving, other emerging technologies like hydrogen storage and thermal storage are gaining attention for larger-scale applications. However, these technologies are less mature compared to BESS.
Overall, battery energy storage systems remain the leading choice for peak shaving applications due to their widespread availability, efficiency, and cost-effectiveness.
