1. Smart Grid: Opportunities in the Data Center January 22, 2010 Charles O’Donnell, Vice President, Engineering Liebert AC Power Emerson Network Power

2. Data Center Facts U.S. data centers consume between 20 and 30 billion kWhr per year Data center energy consumption is expected to double every six years Roughly half of the energy used by the data center is actually consumed by IT equipment Loss of power to a critical data center can cost millions of dollars per incident 2

6. What Smart Grid Will Mean to You Adjust usage in response to real-time pricing –Dynamic load shedding to reduce demand during peak times –Coordinate energy usage to level load Protect critical functions –Shed non-critical loads in response to level of grid stress –Transfer loads to distributed generation Sell excess generation capacity –Reverse metering –Spot and day-ahead markets Sell ancillary services –Voltage and frequency support –Reactive power compensation Source: The Smart Grid: An Introduction U.S. Department of Energy, 2008

16. Takeaways Focus on managing energy consumption in data centers will continue –Data center managers will explore every option to save energy, including some that may compromise reliability Future data center power systems will include energy management features, such as energy storage and VAR correction –But current technology is not ideally suited to this application Data center load management in response to signals from the Smart Grid is a practical application –Maximum benefit will require coordination of IT and facility management Interest in renewable energy in the data center will increase
