C&I BESS

FAQ

How does a C&I BESS help reduce my business's operational costs?

The system primarily reduces costs through Peak Shaving and Time-of-Use (ToU) optimization. By discharging stored energy during peak-rate periods and charging during off-peak hours, you can significantly lower your monthly demand charges and energy consumption costs.

What is the typical ROI for a 125kW/241kWh energy storage system?

ROI varies by region based on local electricity tariffs and available subsidies. On average, businesses in high-tariff markets see a return on investment within 3 to 5 years. We can provide a detailed financial simulation based on your specific utility bill.

What is "Peak Shaving" and why is it critical for factories?

Peak Shaving involves using the BESS to cap the maximum power drawn from the grid during spikes in demand. For factories with heavy machinery, this prevents expensive surcharges and penalties from utility companies for exceeding allocated capacity.

Can I monetize my BESS through Grid Services?

Yes. Depending on your local grid regulations, our smart EMS allows you to participate in Demand Response programs or Frequency Regulation, turning your energy storage into a revenue-generating asset.
