Remember, 1,000 watts = 1 kilowatt, so we need to divide by 1,000. Using the above example, the equation to determine peak kW is: (300,000 watts) / 1,000 = 300 kW. Kilowatts are important to forecast because they determine the other half of your electricity bill, utility distribution, or delivery costs.
