Scenario : A manufacturing plant with high electricity costs and fluctuating loads
Storage System : 500kW/1MWh lithium iron phosphate (LFP) battery storage cabinet
Features :
Peak Shaving : Charges during off-peak hours (¥0.3/kWh) and discharges during peak hours (¥1.2/kWh), completing one cycle per day.
Demand Control : Smoothes load peaks to reduce transformer capacity fees.
Economics :
Annual savings: ~¥500,000, with a payback period of 4-5 years.
Local subsidies (if available) can shorten payback to ~3 years.
