ANNOUNCEMENTS
Internet and Communication Technologies (ICT) have become an integral part of modern life and serve as critical enablers of economic development worldwide. These technologies have acted as force multipliers, accelerating innovation, expanding access to information, and transforming industries. This ICT revolution has been led by the telecom towers and mobile devices, which have made mobile connectivity and broadband services possible at every corner of India. These developments have been further complemented by the emergence of mobile applications, digital government services, and mobile-based payment platforms, all of which have deepened mobile penetration across both urban and rural areas.
Telecom towers are primarily powered by electricity from state distribution companies (DisComs). However, due to frequent grid power outages, Diesel Generator (DG) sets are commonly used as backup power sources. While these energy sources have supported the growth of mobile services, they have also significantly contributed to carbon emissions and Green House Gases (GHGs), thereby exacerbating global warming and climate change. With the rollout of 5G in recent years has further driven the installation of high-capacity telecom towers and small cells, leading to increased energy demands. With over 8.25 lakh telecom towers as of March 2025, India’s telecom sector contributes considerably to national GHG emissions, with towers accounting for approximately 65–70% of the sector’s total energy consumption.
India, as the world's second-largest and fastest-growing telecom market, now faces a major challenge: balancing rapid digital infrastructure expansion with environmental sustainability. In the context of global climate change, the role of carbon emissions and GHGs is well known and requires efforts to reduce them by all sectors of the economy. The telecom sector is also under increasing pressure to reduce its carbon footprint. This calls for a comprehensive strategy that includes: (1) deploying energy-efficient network equipment, (2) optimizing network operations to consume energy whenever necessary, (3) improving energy storage systems to reduce DG set reliance during power outages, and (4) adopting renewable energy sources such as solar and wind to replace conventional grid and diesel-based power. This thesis is focused on policy analysis of Green Energy for Telecom Towers in India. The thesis has been structured around three key objectives. First, it evaluates the steps taken by government agencies over the past decade to green the telecom sector, including a study on the effectiveness of the policy initiatives. Second, it assesses the efforts by telecom service providers (TSPs) and Tower Companies(Towercos) to migrate from conventional power sources to hybrid models combining grid power, DG sets, and renewable energy sources, while also identifying the practical challenges faced during this transition. Finally, stakeholder feedback was collected through a structured survey consisting of two sets of questionnaires to understand ground-level barriers, policy expectations, and suggestions/feedback for fostering a more environmentally sustainable telecom ecosystem.
Research findings reveal that while both regulators and industry players have taken promising steps, large-scale progress is hindered by several persistent barriers. High capital investment required for renewable energy systems remains a major deterrent—particularly for smaller companies. Though renewable energy proves cost-effective over time, the initial high expenditure on solar panels, inverters, and storage systems requires financial support mechanisms from the Government. There are other challenges like technological constraints, skilled man-power in rural areas, and varying climatic and geographic conditions across India also affect the performance and feasibility of renewable energy systems. There are substantial policy implementation gaps, and actionable measures at the state level have been inconsistent.
The research concludes with a set of policy recommendations to support a green transformation for India’s telecom towers. These include strengthening regulatory mandates with enforceable energy efficiency targets and mandatory reporting of energy consumption and emissions, Promoting innovation and indigenous R&D in energy-efficient hardware, storage systems, and AI/MLpowered energy management platforms, capacity-building and sharing of best practices amongst various agencies like central, state and local governments, streamlining state-level regulations and introducing single-window clearance systems to facilitate rapid deployment of green solutions for telecom towers and financial support through tax incentives and soft loan support for encouraging migration towards green energy for telecom towers in India.
In summary, aligning India’s telecom growth with its environmental commitments is both a necessity and an opportunity. With coordinated action from policymakers, industry stakeholders, and technologists, India can build a sustainable, low-carbon digital infrastructure that not only supports its development goals but also positions it as a global leader in green telecom innovation.
