Question: how to calculate electricity maximum demand?
Answer: 3000 kWh divided by 720 hours = 4.16 (demand limit if at 100% load factor) 4.16 divided by .60 = ~7kW. 20kW multiplied by 720 hours = 14,400 Total kWh (if at 100% load factor) 3000 kWh divided by 14,400 Total kWh = 21% load factor at 20kW.
