PUE: power usage effectiveness at South Hill

PUE: power usage effectiveness at South Hill

What is PUE? Power usage effectiveness (PUE) is a metric used to determine the energy efficiency of a data center. PUE is determined by dividing the amount of power the data center utilizes by the power used to run the computer infrastructure within it. PUE is therefore expressed as a ratio, with overall efficiency improving as the quotient decreases toward 1.

3.0 MW - Conventional Data Center PUE = 1.9 Power Cost - $0.09/kWH 3,000 kW @ 1.9 PUE = 5,700 kW @ .95 Load Factor x 24 x 365 = 47,435,400 kWH @ $0.09 kWH = $4,269,186

3.0 MW – South Hill Data Center PUE = 1.4 Power Cost - $0.058/kWH 3,000 kW @ 1.4 PUE = 4,200kW @ .95 Load Factor x 24 x 365 = 34,952,400 kWH @ $0.058 kWH = $2,027,239

Annual Sustainable Savings: $2,241,946
