India's 700,000 diesel-powered telecom towers face a structural energy crisis. Here is how Cosmos Power's hydrogen-BESS architecture eliminates diesel dependency at zero CAPEX while meeting 5G uptime standards.
India has 700,000+ telecom towers. Every single one needs uninterrupted power 24 hours a day. The telecom sector is the second-largest consumer of diesel in India, consuming an estimated 2 billion litres annually and producing approximately 5 million tonnes of CO2 every year. With diesel prices rising sharply in 2026 and 5G rollout accelerating power demands, the fuel cost problem is getting structurally worse before it gets better.
Overview
The company faced operational inefficiencies like fragmented delivery routes, underutilised cargo loads, and a lack of visibility into fleet performance. These issues not only inflated transportation costs but also led to higher carbon emissions—contradicting EcoWare’s commitment to reducing environmental impact.This case study explores how a tailored freight optimisation strategy transformed EcoWare’s supply chain, delivering measurable cost savings, improved operational efficiency, and a significantly reduced environmental footprint.
The Challenge
India's telecom infrastructure runs on diesel by default, not by preference. In 80-90% of rural tower sites, diesel generators meet the majority of power requirements due to unreliable grid supply. Widespread outages lasting 4-6 hours daily are common across multiple states. Meanwhile:
Diesel prices rose by INR 22/litre in March 2026 and continued rising through May
5G base stations consume 2.5 to 3 times more power than 4G equivalents
India's 5G subscriber base is projected to reach 690 million by 2028
DoT and TRAI green energy directives are tightening compliance requirements
Fuel logistics to remote sites adds operational complexity and cost beyond the fuel price itself
Our solution
Cosmos Power deploys a three-layer integrated energy architecture for telecom tower sites:
Solar generation with BESS time-shifting handles daytime generation and evening peak demand
VapourGen PEM hydrogen provides extended backup beyond 4-6 hours, replacing diesel entirely
AI energy management optimises dispatch across all layers, predicts outages, and manages multi-site portfolios centrally
Zero CAPEX Energy-as-a-Service model means operators pay per kWh with no upfront investment
Sub-millisecond response time meets 5G uptime requirements with no interruption at handover
Key results and impact
The Cosmos Power blueprint for a 500-tower rural cluster in Rajasthan projects the following outcomes versus the current diesel-dependent model:
Diesel eliminated across all tower sites
100%
Annual energy infrastructure cost savings per 500-site cluster
INR 27cr+
