Telecom tower company Indus Towers will make 20,000 of its sites or 20% of its network diesel-free by April 2013 at an investment of up to Rs 165 crore as part of an initiative to reduce carbon footprint, a top company official said today.
Indus Towers is a joint venture between telecom majors Bharti Airtel, Vodafone and Idea Cellular.
The company has already turned over 8,900 towers in its portfolio of 1.10 lakh diesel-free and will work towards taking the number to 20,000 by April 2013, Chief Executive BS Shantharaju told reporters here.
Making a tower diesel-free entails an investment of up to Rs 1.5 lakh, he said, adding though capital cost of setting up a site is much higher, the operational cost is lower.
Due to frequent power disruptions across the energy-deficient country, mobile tower firms depend on the carbon-emitting diesel for keeping the towers running.
To go diesel-free, Indus will enhance electricity supply at the site, augment battery bank, deploy free cooling unit and increase usage of solar power interventions, he said.
