Data Center operators want to allocate these costs in as fair a way as possible. If they allocated the costs by the amount of relative space that each tenant has then the allocation could be (would be) distorted due to differences in power consumption density within the suite. One tenant with a relatively small space, but with super high-power-density may be consuming a huge amount of cooling, while another tenant with very large space that is sparsely populated may be consuming very little cooling.

The correct solution, and one which has been adopted by the industry, allocates the additional costs based on how much power your space consumes. Power consumption translates nicely into heat produced and therefore heat that must be removed, hence how much of the overall cooling capacity you are utilizing.

Data Center Operators have become pretty sophisticated in understanding and allocating these shared costs. In my most recent review, I found that the allocation among different Data Centers varied between 45% and 65% upcharge. Putting it differently, for every dollar you spend on electricity; the Data Center will assess and additional Forty-Five to Sixty-Five Cents.

Taking the example, we used above, and assuming a 60% upcharge for the Data Center you select, your actual bill for electrical service would be:

Cost of electricity ($7440) + Upcharge (.6 X $7440) = $11,904
