Aircel is a joint venture between Maxis Communications Berhad of Malaysia and Apollo Hospital Enterprise Ltd of India. It started operations in the year 1999. In a short span of 18 months since 2007, Aircel has expanded its reach from 10 telecom circle to 18 circles out of the total 23 circles. Moreover, it has licenses secured for the remaining 5 telecom circles. This quick transformation involved consolidation of Aircel’s 5 separate datacenters into 1 single datacenter to control operations all over Aircel’s network.

What according to you is the USP of the project? What were the key business benefits gained after having deployed this project? By deploying Adaptive Cooling methods, the wastage of coolant was minimized. Optimal utilization of the cooling plant has been made possible by the Adaptive Cooling, EAT and specific coolant usage that emits less CFCs. Sensor based lighting systems has brought down the power wastage considerably. |

The Green IT initiatives at Aircel were taken up as separate projects with measurable KPIs. These green initiatives were designed and implemented by Wipro Eco Energy, the clean energy division of Wipro. The automation in IT service management and operations process gave immense benefits by measuring the IT service performance with all type of analytics/reporting and approval on Web and mobile. These solutions have reduced the overall carbon footprint of the datacenter by over 400 tons per year. Few of the technologies implemented for green data centre were-- Adaptive Cooling Technology, Geo-thermal exchange, Earth Air tunnel (EAT), lighting solutions, solar thermal solutions, which has contributed to the save earth initiative through effective preservation and reduction in climate control variables. By using these technologies, the datacenter’s cooling system was enhanced, and there was about 20-25% improvement in efficiency of the chillers due to geothermal heat-exchange and Earth Air Tunnel system.
Rain water harvesting was implemented, wherein run-off water from the roof was captured and directed toward percolation pits to recharge the ground water. Considering an average rainfall of 511mm, 500 KL water will be charged to the ground Geothermal Exchange. 28 thermal wells drilled around the building and vertical looping system is used to transfer heat from HVAC system to ground. Three 20 tons GSHP are being used, totaling 60 tons for comfort cooling bed. This has replaced conventional cooling system of 72 ton, thereby saving power. In the cooling systems, refrigerant R410A is used instead of R22 or R407 leading to better energy efficiency and lowered costs.
Sensor based lighting systems are used which turns on the lights only for the occupied areas. LED lights used in place of 36W CFLs reduced the power consumption by 26 KW/day. Solar energy based heating system is also used to provide 1000 LPD of hot water supply saving on the 12KW of power that a conventional heating system would use.
Aircel has migrated all of its OSS/BSS and other systems to this Green data center. Considering the pace of industry growth, Aircel forsees the needs to build three more such data centers of similar or even higher capacity. They also have a roadmap planned for developing a public and private cloud for appropriate applications. This data center is also in the process of getting a LEED’s certification.
