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 k. Wh in 2008 with an estimated total electricity cost of $ 5. 0 Billion DATA CENTER Power Supplies, Cooling UPS Generation & Distribution 100% 22 Mission Critical Apps 16% 30% . 003% Silicon 1% Servers

Where Does Power Go? IT Equipment = 30% Energy Equipments = 25% Cooling = 45% § § 33 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 Source: APC View

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! • Source: EPA Report

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 IBM Example than 40%; § § Asset utilization rates increasing 2 x-4 x; § 55 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 Source: IBM Client Survey

Conventional solutions & associated problems Problems with Conventional systems • Unhealthy Grid • High DG running costs • Higher capacity DG’s 15/25 KVA DG IT, Servo, AMF, Alarm box ACDB etc GI: GI Shelter 77 1. 5 x 2 2. 0 x 2 Tr AC’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 Challenges Contributor/Reasons Site Operation Cost • • • Site Downtime Project , Operation and Maintenance 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 15 KVA DG for 3 KW load) Main Reasons • Battery • Generator • Air-Conditioner • • • Installation Time Expandability IT Interface for critical and operational need monitoring Innovative ‘s Solutions • • • 88 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 5 kw Next. Gen thin Plate Technology Aviation grade very high MTBF DC Generator Compressor less N + 2 redundancy 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 99
