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!

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.
