Tata Docomo has spent some Rs 100 crore, or about US$15.8 million, in the last 18 months to “green” 10,000 sites under an initiative called Project Optimus. The project’s goal was to reduce the carbon of the sites located across 20 circles, or regions, in India.
The project has resulted in annualised savings of Rs 98.97 crore of operating expenditure, 67,865 megawatt of electricity, 8,436 kilolitre of diesel and massive reduction in carbon footprint, according to Tata Teleservices VP Saji Mathew.
As part of the scheme, the operator designed a special outdoor cabinet for the sites, which deployed advanced heat exchange technologies for cooling. The scheme currently worked through sites operated by Viom Networks and American Tower Corporation, but the operator is also talking to other tower infrastructure operators.
According to a report by Economic Times, Tata is now sourcing new equipment that do not require cooling equipment, looking at lithium-ion batteries and diesel turbine generators to optimise site power, and is also considering fuel cells as an alternative power system.
