3. Smart Grid – Principal Characteristics What experts say about Smart Grid 1 …What data center operators think… Self-HealingWill I see fewer outages? Shorter outages? Will I need my UPS? Active Customer ParticipationSounds 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 21 st 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! 1.

7. 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

8. Demand Management Overview There 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 Source: Emerson Internal

10. 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

11. 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.
