Efficiency Payback Comparison Calculator
Is a premium efficiency motor worth the premium? You decide. Here's an example: A local manufacturing plant operates a piece of equipment 24 hours a day (8760 hours per year). The local utility charges 9 cents per kilowatt hour. This piece of equipment needs a new 25 HP 1800 RPM motor. Based on the annual savings formula, the premium efficient will save over $200 per year. Try it yourself. Take a couple of typical installations in your plant. Plug in the numbers in the payback analysis. Based on your individual situation, is it worth the premium?
