A new machine is required to upgrade a process. The equipment to drive the machine is rated at 200 horsepower and will operate on full load for 8760 hours per year. The equipment’s efficiency is 90%. Because the equipment is fairly large, a demand charge of $90 per kilowatt per year will be incurred in addition to an energy charge of $0.08 per kilowatt-hour.
