Calculating Cost to Operate Electric Motor for 1 Hour

Energy companies charge on an average of 11cents for kWh(Kilo Watt Hour). Most electric motors will provide the watts the motor uses for an hour however an alternative to find this is amps multiplied by volts.

1 kWh = 11 cents

1000 watts = 1 kWh

Amps x Volts = Watts

Hotels

Hotels have many motors that operate throughout the day and use large amounts of energy. Hotels also have motors that operate 24 hours like a pool or whirlpool Motor. By reducing the amperage of the motor on typical a 40% savings is possible per day.

Without PFCD
Typical Pool or Whirlpool Motor is 1.5 Horsepower and Operates at 220 volts at 9.9 amps

9.9amps x 220volts = 2178watts = 2.1 kWh = 24cents per Hour or $5.76 per day or $172.80 per Month

With PFCD - 1200
Typical Pool Motor is 1.5 Horsepower and Operates at 220 volts at 9.9 amps

5.1amps x 220volts = 1122watts - 1.2 Kwh = 14cents per Hour or $3.36 per day or $100.80 per Month

Savings of $72.80 per month or $864.00 per year on a single Motor or $145.60/month on both the Pool and Whirlpool Motor or $1728.00/year

Residential Customers

Your home can benefit from a PFCD, a 2500 sq ft home will generally have a washer, dryer, refrigerator, Air Conditioning, Heating, ceiling fans and many other high electric consuming items. By using a PFCD device the residential customer, can save by lowering the total amps used and thus reducing the Power Factor for an overall savings of 15 - 25%.

Without PFCD

Average Household 990kWh/month = $109.00/month = $1308.00/Year

With PFCD - 1200

Average Household 730kWh/month = $81/Month = $975.00/Year Savings of $400.00
