1 Data Center Combined Heat and Power Benefits and Implementation Justin Grau, Google Inc. Sam Brewer, GEM Energy

2 Data Center Challenges Electric Load Densification Thermal Dissipation Requires constant cooling Power limits from utility Electric costs Unreliable electric grid Moore s Law

3 Market Fundamentals Energy has been very inexpensive traditionally A wasteful energy economy has evolved that is running into limits to growth As limits are approached or exceeded, energy prices become expensive and reliability decreases Growth in population and standard of living puts pressure on our energy system Environmental degradation issues are related to our energy system Regulatory bias against clean energy technologies is being removed

4 Risk Electric supply availability and quality is the key variable for data operations Current planning does not adequately address reliability for long duration electric outages (48 hours+) Computers run almost everything Diesel reciprocating generators are not reliable for long duration events Standby diesel generator have high emissions due to the costs of adding emission reducing equipment

5 Legacy Electrical Distribution Model

6 Current Legacy Data Center Normal Operation Diesel Fuel Storage Utility Provides Electric Power UPS provides quality control of electricity Diesel Generators Battery System Central Grid Utility Switchgear UPS PDU IT Equipment Infrastructure Chillers DX Units Pumps Lights Cooling Interface / Infrastructure Key Raw Electricity Clean Electricity Fuel Chilled Water

7 Current Legacy Data Center Emergency Operation Diesel Fuel Storage Utility is absent UPS components fail because of generator output quality Diesel Generators provide power Diesel Generators Battery System Central Grid Utility Switchgear UPS PDU IT Equipment Infrastructure Chillers DX Units Pumps Lights Cooling Interface / Infrastructure Key Raw Electricity Clean Electricity Fuel Chilled Water Cooling system becomes less reliable because of power quality and switching Reliability decreases to ~0 after 1 2 weeks

8 Distributed Generation Model 50% fewer links in the distribution chain Resource Recovery Gas Distribution End User Gas Drilling Company Gas Utility You

9 On Site Power Generation Technology Needs a primary fuel Must operate unattended and be reliable Must be cost effective Must be less polluting than the utility

10 Benefits of CHP over 1MW Legacy Data center Increased Reliability Tier 4 data center (Uptime Institute) 4 hour outage in any 5 year period 48 minute outage in any 1 year period CHP Data Center (US EPA) CHP + 1 utility feed provides for an expected 43 minute outage in any 1 year period CH + 2 utility feeds provides for an expected 7 minute outage in any 1 year period

11 Green Data Center CHP Retrofit Reduces Operational Costs Additional network deliverable fuel source Alternate cooling technology Environmentally friendly

12 Green Data Center New Build

13 Green Data Center New Build 2

14 Benefits of CHP over 1 MW Legacy Data center Reduced annual electricity costs Utility= $1,350,000 CHP= $390,000 Decreased annual emissions (metric tons) Utility CO2= 10,800 Nox= 12.5 CHP CO2= 5,300 NOx= 1.6
