Reduce Demand Charges with Battery Storage
When adding DC fast-charging stations, your peak demand usage can increase by the rated output power of the charger. For example, if you install one 50kW fast charger, your peak demand would increase by 50kW when that charger is used. If you have demand charges of $30, this could amount to $1,500 extra per billing cycle.
