Discuss how decarbonising digital infrastructure such as telecom towers can contribute to India's climate goals. What are the bottlenecks?

India has more than a million telecom towers. Many in remote areas rely on diesel generators for backup power, which are costly and carbon-intensive [2]. The October 2026 Cygni Energy–Indus Towers MoU plans to explore up to 1.5 GWh of BESS manufacturing for telecom sites [1]. Cleaning up this "invisible" power demand can support India's net-zero 2070 pledge, but real hurdles remain.

Contribution to climate goals

• Replacing diesel: battery or hydrogen fuel-cell backup can replace diesel generators at off-grid sites [2].
• Emission savings at scale: a government estimate says just 4,000 MWh of BESS can cut about 1.3 MMT of CO₂ a year [4]. Thousands of tower batteries could add similar savings.
• Renewable integration: paired with rooftop solar, tower storage fits the 208 GWh BESS needed by 2030 under the National Electricity Plan [3].
• Industrial co-benefit: steady telecom demand supports domestic cell-making under PLI-ACC (50 GWh, ₹18,100 crore) [3]. This reduces import dependence.
• Falling costs: bid-discovered BESS cost has fallen steeply [5], so clean backup is becoming economically viable.

Bottlenecks

• Storage is not generation: during long grid outages a battery still needs the grid, solar or diesel to recharge it. Without on-site renewables, diesel use continues.
• Cost mismatch: low grid-BESS tariffs assume two cycles a day [5]. Tower backup batteries cycle less often, so each unit of stored power costs more.
• Policy gap: VGF covers up to 40% of capital cost, but 85% of power must first go to Discoms [6]. Captive tower storage therefore gets no VGF support, and there is no framework to group tower batteries as distributed storage.
• Manufacturing constraints: PLI-ACC firms face unavailable technology, skill gaps and imported machinery [7]. A new plant will face the same problems.
• Non-binding commitments: the MoU only "explores" collaboration. It sets no timeline, location or investment [1].

Telecom decarbonisation links India's digital ambitions with its climate goals. To make it work, the Ministry of Power and the Department of Telecommunications should create a captive-storage support window and rules that let tower batteries be grouped as distributed storage. Solar-plus-storage at tower sites and stronger domestic cell supply chains should go with it. Together, these steps would help India meet its Panchamrit commitments and SDG 7 and SDG 13.
