A small manufacturing plant on a single three-phase service consumes 126,000 kWh of electrical energy over a monthly billing period. Peak demand is typically measured at 400 kW during the day and 200 kW at night. However, because of an abnormality in plant operation, demand for power increases to 1200 kW over a 15-min period on one day during the month.
