      Opportunity for Savings in Data
                 Centers

• In data centers >50% of delivered power is
  used by core operations
  (US DOE estimate)

• Power conversion and distribution
  accounts for 20% of the wasted power
• Lowering power conversion losses represents
  a substantial opportunity for savings



                                                3
Why Are Transformer losses So Often
             Ignored ?




                                      4
       DOE Identifies the Need for Efficiency
       Based on Dept. Of Energy Study


• Approx. 40 million dry-type transformers
• Economic & Grid Impact
   – 60-80 Billion kWh losses
   – 9 days generating capacity
   – Annual Cost $3-4 Billion/year
• Environmental Impact
   – Requires burning 145 Million tons of coal
   – Resulting in CO2, Acid Rain, Smog

 DOE drives move
From low first cost
   Efficiency to
Low Life Cycle Cost

• EPACT 2005/NEMA TP1
  is minimum efficiency –
  to rid market of worst
  offenders
• Significant losses remain
