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

Where Does Power Go?

IT Equipment = 30%

Energy Equipments = 25%

Cooling = 45%

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/hrsMillions of Tons of CO2

• I.T Does as much damage to environment as Airline Industry

• 2% of CO2 Emitted comes from I.T Industry

• For every 1 spent powering systems 0.5 to 1 spent on cooling I.T is the focus of GREEN lobby! Source: EPA ReportSource: EPA Report

Green Buildings

IBM Example

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 than 40%;

Average payback of <2 years in Data Center Energy Efficiency assessments;

Asset utilization rates increasing 2x-4x;

Deferral of massive capital investments in new datacenter builds

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

Conventional solutions & associated problems

• Unhealthy Grid• High DG running costs• Higher capacity DG’s

• Operational problems• Low efficiency in Power utilization (85%)

– Leading to Heat losses• Slow Voltage regulation time leading to

– SMPS Failure– High maintenance

• Large foot print• Excessive cabling • Frequent breakdowns with no monitoring

of passive infrastructure elements

• Shelter• High solar gain• Non modular• Rusting problem

• Air Conditioning• Oversized AC’s• Very High Inrush Current• No Free Cooling

Addressing ChallengesChallenges 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

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

Use of technology for reducing energy costs

• Air Conditioning– Next Generation Cooling solutions (for Indoor BTS)– Battery Cooler (for Outdoor BTS)

• Battery back-up power– High efficiency and cycle life batteries– Float Mode operation for extended life

• DG based power– Cost of DG running to be reduced– Move site to DC Power architecture which creates future proof

site– Explore Alternative technologies like wind/ solar or fuel cells

• Energy losses in SMPS & PIU– New products offering high efficiency– Wide operating range to reduce DG running

• Integrated NMS– Integrate Tower Management (Through SMS and GPS) with

overall NOC
