Discussion Points

What is driving the emphasis on energyefficiency in the IT/Data Center/High Techsector?

What’s happening on the ground withPG&E, leading high tech companies, andutilities across the nation.

What are the likely developments in thenear term.

3

Let’s Look at High Tech…

PG&E serves Silicon Valley – almost all of theindustry heavyweights have a presence there

They mostly operate office space and someresidual clean rooms

Mostly, the focus is on data centers

4

…in Northern California

A total load of 400-500 mW (2.5% of total)

“Enterprise” centers are known

“Corporate” centers are hidden

“Closet” servers are invisible

Key issue for enterprise and some corporatedata centers: space cooling power

Situation so dire, that the industry is moving to…

5

…“Instant” Data Centers

6

Where’s the Data Center?

7

Here’s the Data Center!

8

Response to Power/Space/Cooling

“Efficiency” comes to the forefront, but it is largelydue to growth and constraints, notfor environmental responsibility.

Proof Point 1:Companies chasing cheap power locations

Proof Point 2:Old design habits are dying hard (or hardly dying)

What PG&E Offered pre-2006

Audits, incentives that addressed coolingsystems only:

High-efficiency equipment(chillers, pumps, fans, etc.)

Air- and water-side economizers VFD’s

What we were missing:

Anything having to do with operations “insidethe white room”

10

What We Were Missing

Energy use in a high-performance data center (LBNL/PG&E Study)

HVAC30%

LightingOther12%

Servers &Data Equipment

55%

fans, compressors,and others

3%

11

More Importantly

The Information Technology managersrun the show at data centers, not facilitymanagers.

Programs and services that address coolingonly address one aspect of the challengesfacing these customers.

12

New Initiatives in 2006

Incentives for energy-efficient computingequipment (Rip & Replace only)

Incentives for virtualization/server consolidation

Incentives for airflow control systems

Incentives for high efficiency UPS and powerdistribution systems

Integrated, high quality, technical services

13

Coming in 2007 Incentives for energy efficient computing equipment

(new installations)

Focus and incentives on efficient data storagetechnologies

Retro-commissioning program for airflowmanagement

Integration of demand response into data centermanagement!

Incentives for conversion to liquid coolingtechnologies

80+ program for computing equipment

Increased focus on distributed systems: thin-clientconversion, PC management

14

Results

Industry agrees that a third to a half of datacenter energy use can be addressed throughenergy efficient technologies and strategies

PG&E doubles expected performance in thissector

PG&E announces formation of national utilitycoalition to extend program adoption.

15

Predictions

Near term winners:

Widespread adoption of virtualization forcomputing and data storage

New data storage technologies (MAID)

Integrated data center energy management(virtualization 2.0, control of equipment andcooling systems)

Equipment metrics place high emphasis onefficiency as part of performance

16

Predictions

Mid-term winners:

Increased regulatory attention?

Evolutionary power conditioning, management,and delivery systems

Industry move to liquid cooling

Long-term winners:

On-site generation, demand management

Truly “green” data center designs
