Airtel, Indus Towers Step Up Push to Reduce Diesel Dependence at Telecom Sites

Indian telecom operator Bharti Airtel has continued expanding solar power deployment across its network infrastructure. Over the last two years, Airtel has solarised nearly 27,000 network sites. “We are amplifying our efforts, in collaboration with Indus Towers, to significantly reduce dependence on diesel by transitioning to high-powered batteries and alternate sources of energy,” Bharti Airtel said in its recent Q4 FY26 release dated May 13, 2026.

Key Highlights

Bharti Airtel has solarized nearly 27,000 telecom network sites over the last two years.
Airtel currently operates around 42,000 network sites with solar energy access across India.
The company aims to eliminate diesel dependency by deploying high-powered batteries and renewable energy solutions.
Frequent power outages and rising diesel prices are increasing operational costs for telecom tower infrastructure providers.
Airtel’s collaboration with Indus Towers is focused on scaling clean energy adoption and improving network sustainability.

Why Telecom Towers Depend on Diesel Backup Systems

Telecom infrastructure is deployed extensively across the country, with lakhs of BTS towers and small cells requiring electricity to operate. In the event of power failures or interruptions, telecom equipment falls back on battery, diesel, or solar backup systems to provide users with uninterrupted connectivity. You may have encountered situations where specific towers or locations experience poor connectivity or a “No Network” state during power disruptions. These issues are often caused by prolonged power outages, diesel supply constraints, and rising fuel costs.

Rising Fuel Prices Increase Pressure on Telecom Infrastructure Providers

According to the industry body Digital Infrastructure Providers Association (DIPA), widespread power outages in several states, with disruptions lasting between four and six hours daily, have significantly increased reliance on diesel generators for backup power. According to media reports on Tuesday, May 19, 2026, diesel prices increased by 91 paise per litre and petrol prices by 87 paise per litre, marking the second increase within a week. This is expected to increase operational costs for infrastructure providers and the telecom industry overall, making it less viable for operators to continue running towers on diesel-based backup systems.

Airtel and Indus Towers Focus on Clean Energy Transition

In a statement, Gopal Vittal, Executive Vice Chairman, said:

“…a major focus for us is to completely eliminate diesel from our operations. We are working with Indus Towers to scale clean energy.”

During the Bharti Airtel and Bharti Hexacom Q4 FY26 Earnings call, Soumen Ray, Group Chief Financial Officer, said:

“With Indus, we are working towards significantly reducing dependence of diesel by transitioning towards high-powered batteries and renewable power. We strongly believe that work across these areas will provide meaningful outcomes with superior revenue growth and cost efficiencies.”

During the Q4 FY26 Earnings call, Shashwat Sharma, Managing Director and CEO (Airtel India) said: “A key focus area is increasing the use of energy from alternate to renewable sources. This is reflected in our continued expansion of solar power deployment across our network infrastructure. We ended the year with 42,000 network sites which have solar access. Over the last 2 years, we have solarized nearly 27,000 network sites.”

Airtel’s War on Waste

Speaking about cost pressures on the company, Sharma said: “The last and fourth pillar of our strategy is war on waste. As there are cost headwinds on both OpEx and CapEx, I want to underscore that we have widened the funnel to identify and eliminate waste across the organisation. While unpredictable scenarios are playing out globally, the cost pressures we are seeing today remain confined to a few specific areas, particularly in servers and memory prices, as well as availability of these components. Significant steps to re-engineer and redesign are underway in the organisation to mitigate these pressures.”

Reduce Dependency on Diesel Consumption

Commenting on reducing diesel consumption, Sharma added:

“We’ve also taken significant steps to reduce our dependency on diesel consumption across our sites. These initiatives are beginning to deliver meaningful outcomes, and we believe there is a lot of work still to be done in this space of war on waste. To sum up, overall we delivered another year and a quarter of strong performance, underpinned by strength of our diversified portfolio and sharp execution. Looking ahead, we continue to see large growth opportunities across mobility, led by ARPU growth through portfolio premiumisation and postpaid, rapid expansion of homes, and across B2B.”

Conclusion

It appears that Airtel is aiming to completely eliminate diesel from its network operations. From its Green 5G initiative and efforts to enhance energy efficiency through tower solarisation to its plan to phase out diesel use across network operations, the company is pushing toward cleaner, more sustainable telecom infrastructure. If these initiatives scale successfully, Airtel users could experience more reliable network connectivity with reduced dependence on diesel-powered backup systems. India’s telecom sector may gradually move toward greener and more energy-efficient networks in the coming years.
