Smart Grid – Principal CharacteristicsWhat experts say about Smart Grid1… What data center operators think…
Self-Healing Will I see fewer outages? Shorter outages? Will I need my UPS?
Active Customer Participation Sounds good, but what does it mean?
Resilience to Human-caused and Natural Disasters and Cyber-attacks
Nice. I’m still recovering from 2003.
Enhanced Power Quality and Reliability for 21st Century Loads
It’s about time.
Support of All Generation and Storage Options
Generation? Storage? I have those!
Enable New Products, Services and Markets
I guess I can expect a call from my local IT reseller.
Asset Utilization and Operational Efficiency Now you’re speaking my language!

Data Center Energy ManagementElectricity In Heat Out
1 out of 500 data centers will have a severe disaster each year1
40% of companies take a day or longer to bring records back online1
A rolling blackout across Silicon Valley totaled $75 million in losses2
The Northeast blackout of 2003 resulted in a $6 billion economic loss to the region2

Optimizing Within a Layer Creates Gaps: Bridge the Gaps to Maximize Smart Grid Benefits
For data centers, Smart Grid promises many benefits: greater control of power consumption, energy efficiency and cost reduction. It will also create a new layer of data to support critical decision making about energy usage. For organizations to fully realize these benefits and utilize the data provided, they must bridge the gap between IT and
facilities. Source: Emerson Internal
Demand Management OverviewThere are two elements to demand management – demand response & demand control
Demand Response Driven externally by a power utility provider Responds to the condition of the power grid as
signal to curtail loads (wholesale price or grid capacity)
Can be either manual or automated Savings based on pricing incentives “economic” or
“reliability” (ISO/utility dependent) Enabled by ProAct’s ability to command & execute
enterprise demand response calls
Demand Control Driven internally by customer to avoid peak
demand power surcharges Limits peak demand by shedding loads in
response to data center power meter Savings based on reducing peak demand or
demand based energy consumption Enabled by power shedding abilities

Data Center Load Shedding Options• Shed non-critical functions
• Degrade response time– Aggregate applications on
fewer servers
– Put servers in power saving mode
• Offload processing– Move processing load among
enterprise data centers
– Move processing load to cloud service provider
• Local generation– Diesel or natural gas
generator
– Fuel cells
– Wind or solar
– Battery
• Raise cooling set point
Preparing for a Smart Grid
Five key steps data center managers can take today:1. Begin talking with the local utility about their Smart Grid initiatives, plans,
incentives and timelines.2. Consult with an energy management specialist to evaluate current and
future energy needs, consumption levels, and patterns.3. Evaluate current building automation and infrastructure management
systems, as well as onsite generation capacity if applicable.4. Develop a strong delineation for load types (critical, essential, and non-
essential) and a policy for prioritization.5. Stay current with local and federal government mandates and regulations
relative to the Smart Grid as well as onsite power generation.
