🔋 BESS 2-4 Hr Storage (Slashing $25/kW Demand Charges, Net Arbitrage ROI)

Commercial BESS Peak Shaving Calculator

Calculate utility electric demand charge reductions achieved by automated commercial Battery Energy Storage Systems (BESS): calculate peak shaving capacity (discharging 250 kW to 1,000 kW during the facility highest 15-minute billing window to eliminate $20 to $40 per kW monthly utility demand charges), and turnkey energy storage retrofit yields.
