Power supply （Daily load curve ）
Reduce maximum demand
Charge to battery
Discharge from battery
■For Customer : Electricity fee saving(Factory/Office) - Reduce maximum demand
- Reduce peak time use by charged power at night ■For Power supplier : Investment deferral by load leveling
Maximum Demand
【Example】 1,000kW/7,200kWh NAS system for Sewerage treatment equipment in Tokyo
■Field Example- In Japan(Maximum size at one site) : 140MW / 1,000MW (12MW / 86MWh)- In USA and Canada(AEP,NYPA,BC Hydro） : 20MW / 144MWh- EDF Reunion Inland : 1MW / 7MWh
