Energy Facts

Of all the potential electricity available in an energy source, only 30 percent reaches consumers

•

An estimated 170 billion kilowatts are wasted by consumers each year due to insufficient power usage information

•

US Datacenters and servers consumed about 670 billion kWh in 2008 with an estimated total electricity cost of $ 5.0 Billion Generation & Distribution Cooling DATA CENTER Power Supplies, UPS 100% 30% 16%

Mission Critical Apps .003% Silicon 1% Servers

IT Equipment = 30% Energy Equipments = 25% Cooling = 45%

Where Does Power Go?

3 3 

Total number of servers installed increased by factor 100 in one decade



Number of server/processors per rack increased by factor 10 in ten years



Power and thermal waste per server increased by factor 5 in ten years

I.T damage to the environment

Billions of KW/hrs Millions of Tons of CO 2

• I.T Does as much damage to environment as Airline Industry • 2% of CO 2 Emitted comes from I.T Industry • For every 1 spent powering systems 0.5 to 1 spent on cooling 4 4 I.T is the focus of GREEN lobby!

Green Buildings

Enhancing existing buildings to be more energy efficient typically reduces total energy consumption by 20-50%...

…

while new “green” buildings have the potential to reduce energy consumption by 80% or more.

Benefits



Average achievable energy savings greater

 

Asset utilization rates increasing 2x-4x;



Average payback of <2 years in Data Center Energy Efficiency assessments; Deferral of massive capital investments in new datacenter builds

$1 energy savings drives another $6-8 operational savings on average

Addressing Challenges

Contributor/Reasons Innovative ‘s Solutions Site Operation Cost

• • • • • Various AC/DC Conversion Cost Backup Cost Environment Conditioning Cost D.G. running cost due to unhealthy grid Over-design Infrastructure for Peak Load (like 15KVA DG for 3KW load) • • • • • Less/low AC/DC Conversion

Low backup cost

Low Air-Conditioning Cost Wide range PIU to maximize low cost grid usage Low back up power cost with DC power house of 5kw

Site Downtime Main Reasons

• Battery • • Generator Air-Conditioner • • • NextGen thin Plate Technology Aviation grade very high MTBF DC Generator Compressor less N + 2 redundancy 8 8

Project Operation and Maintenance Cost ,

• • • Installation Time Expandability IT Interface for critical and operational need monitoring • • • • Installation time (24-48 hours) Expandability modular Energy metering for each operator and their individual load Detailed NMS
