It's Time to Add Power Management to Your Service Catalogue

A lot of people talk about "going green" -- but have you ever done the math to see how power management can assist your company -- and your customers? Take a look at this quick example, involving the cost of running 500 PC desktops year-round in California.

The retail price of electricity in California is 11.53 cents per kW hour. If you run a Vostro 200 Mini (which is a Dell desktop) in California, fitted with Intel Pentium Dual Core E2160 processor and a 17” monitor non-stop for a year, you would burn 1226.4* kW hours. This will cost you $141.40 per year. Now, assume you have a customer in California with 500 such Vostro Minis. He is going to burn $353, 505 for a five year period just on electricity for these desktops.

Here's the math:

  • 65Watts + 75Watts X 8760 hours / 1000 = 1226.4 kW hours
  • 1226.4kW hours X 11.53 /100 X 500 X 5years = $353,505
But the standard business hours 9AM-6PM Monday to Friday contribute just 27% of the overall available time. Take a look:ManageEngine

And in these 45 hours, reports indicate that, only 60% of the time the desktops are actively used. Rest goes in breaks, phone calls, meetings, and discussions. If someone enables strict power management** for the above case, it will result in a savings of approximately $300k
  • $353,505 X 0.73 = $258,058 (for non-working hours)
  • $353,505 X 0.27 X 0.4 = $38,178 (for 40% idle time)
  • Total: $258,058+$38,178 = $296,236
(Note: *Thermal Design Power of E2160 is 65Watts. For monitors its 75Watts. 65+75X8760 hours /1000 =1226.4 kW hour. Refer Wikipedia for TDP of other processors.)
