India’s electricity system stands at a critical crossroads. Over the past two decades, the country has achieved remarkable progress in expanding power generation capacity, improving grid connectivity, and providing near-universal electricity access. Yet the context in which this system operates is rapidly changing. Climate change is intensifying extreme weather events—heatwaves, floods, cyclones, and erratic rainfall—posing serious risks to energy infrastructure. As India moves toward its development ambitions and rising electricity demand, the resilience of the power sector is becoming as important as its capacity.
The Draft National Electricity Policy (NEP) 2026 recognises this emerging challenge. The policy emphasises the need for resilient and flexible power systems that can withstand climate-related risks while integrating large volumes of renewable energy. It also aligns with India’s long-term development vision and climate commitments, including increased electricity consumption, decarbonisation, and net-zero emissions by 2070.
However, the policy arrives at a time when climate hazards are already testing India’s electricity infrastructure. Ensuring that power generation, transmission, and distribution systems are climate-resilient will be central to safeguarding energy security and economic stability in the coming decades.
Rising Climate Extremes and Impact on Power Systems
India is among the countries most exposed to climate-related disasters. Studies indicate that climate physical risks—including rising temperatures, erratic monsoons, floods, and cyclones—threaten a large share of the country’s population and economy.
The scale of extreme weather events is growing rapidly. In 2024 alone, India experienced extreme weather conditions on nearly 93% of the days during the first nine months of the year, including floods, cyclones, heavy rainfall, and heatwaves.
These climate hazards directly affect electricity infrastructure in multiple ways:
Heatwaves increase electricity demand for cooling and reduce the efficiency of power plants and transmission lines.
Floods damage substations, transformers, and distribution systems.
Cyclones and high winds can topple transmission towers and disrupt grid connectivity.
Droughts and water scarcity threaten thermal power plants that rely on water for cooling.
Research examining India’s power outages shows a clear link between extreme weather and grid disruptions. During intense rainfall events, outage durations can increase by 80–220%, while heatwaves can increase outage minutes by 15–60%. Flooding in urban areas can multiply outage times by up to five times.
These findings underscore that climate change is not a distant risk for India’s electricity sector—it is already affecting the reliability and performance of energy systems.
Vulnerabilities across the Power Infrastructure
Electricity infrastructure is inherently climate-sensitive. From power generation plants to transmission networks and distribution lines, each component faces distinct risks from extreme weather.
- Generation Infrastructure
Thermal power plants remain the backbone of India’s electricity generation. However, many of these plants face climate-related vulnerabilities, particularly linked to water availability. Studies indicate that about 40% of India’s thermal power plants are located in water-stressed regions, and up to 70% could face high water stress by 2030.
This has significant implications. Thermal plants require large volumes of water for cooling, and shortages can lead to reduced output or shutdowns. As climate change intensifies droughts and competition for water increases, power generation risks could grow substantially.
Renewable energy infrastructure also faces climate risks. Solar panels can experience efficiency losses during extreme heat, while wind turbines and transmission lines may be damaged during cyclones and storms.
- Transmission Networks
Transmission systems are particularly vulnerable to cyclones, strong winds, and lightning strikes. Transmission towers, which carry electricity over long distances, can collapse or sustain damage during extreme weather events.
For example, studies examining damage during major cyclones in India have shown that high-voltage transmission towers in coastal regions can fail under extreme wind speeds, disrupting power supply across large areas.
Flooding can also submerge substations and damage critical equipment, causing widespread outages and lengthy restoration times.
- Distribution Infrastructure
Distribution networks—the final link delivering electricity to homes and businesses—are often the most exposed to climate hazards. Overhead power lines are susceptible to storm damage, fallen trees, and flooding.
Urban flooding has repeatedly disrupted electricity supply in cities such as Mumbai and Chennai, highlighting the need for improved infrastructure planning and climate-resilient design.
The Economic and Development Implications
Electricity is the backbone of modern economies. Reliable power is essential for industry, healthcare, transportation, digital infrastructure, and daily life. Climate-induced disruptions in electricity supply can therefore have cascading impacts across multiple sectors.
In India’s rapidly growing economy, these risks are particularly significant. Power outages can halt industrial production, disrupt supply chains, and reduce productivity. Hospitals, transportation systems, and emergency services also depend heavily on uninterrupted electricity.
The economic consequences of climate-related disruptions to energy systems could therefore be substantial. As electricity demand grows alongside urbanisation, industrialisation, and digitalisation, the resilience of power infrastructure will increasingly determine the stability of the broader economy.
The Role of the National Electricity Policy 2026
Against this backdrop, the National Electricity Policy 2026 represents an important opportunity to strengthen India’s power sector. The draft policy recognises that developing a resilient and flexible grid will be essential—not only for integrating renewable energy but also for addressing climate-related risks.
The policy also aims to support India’s long-term energy goals, including increasing per-capita electricity consumption to 2,000 kWh by 2030 and more than 4,000 kWh by 2047.
Achieving these targets will require not only expanding electricity supply but also ensuring that infrastructure can withstand increasingly severe climate shocks.
The NEP therefore offers a critical framework for embedding resilience into the planning and development of India’s electricity systems.
Building Climate-Resilient Power Infrastructure
Integrating climate resilience into the power sector requires a combination of technological innovation, infrastructure upgrades, and improved planning. Several key strategies could help strengthen India’s electricity system against climate risks.
- Strengthening Transmission and Grid Infrastructure
Robust transmission networks are essential for maintaining reliable electricity supply. Climate-resilient grid design includes:
Reinforcing transmission towers to withstand higher wind speeds
Elevating substations in flood-prone areas
Installing advanced monitoring systems for early detection of grid disruptions
Expanding inter-regional transmission networks to enhance flexibility
Such measures can help prevent large-scale power outages during extreme weather events.
- Underground Cabling in Vulnerable Areas
In cyclone-prone coastal regions and flood-prone urban areas, underground cabling is increasingly being adopted as a resilience measure. For example, replacing overhead lines with underground cables has helped reduce outages and speed up restoration in cyclone-affected regions of India.
Although underground infrastructure involves higher initial costs, it can significantly reduce damage during storms and improve long-term reliability.
- Climate-Informed Infrastructure Planning
One of the most important steps toward resilience is incorporating climate risk assessments into infrastructure planning. This includes:
Mapping flood-prone areas before building substations
Designing transmission lines to withstand projected wind speeds
Evaluating heat stress on generation and transmission systems
Integrating climate models into long-term energy planning
Such approaches can ensure that infrastructure investments remain viable throughout their lifespan.
- Diversification of Energy Sources
Expanding renewable energy sources can enhance resilience by reducing reliance on single points of generation. Distributed renewable systems—such as rooftop solar and microgrids—can provide backup electricity during large-scale grid disruptions.
Microgrids, in particular, can play a vital role in disaster-prone regions by maintaining electricity supply for critical facilities such as hospitals, emergency services, and shelters.
- Smart Grids and Digital Technologies
Smart grid technologies can significantly improve the resilience of electricity networks. Digital monitoring systems can detect disruptions in real time, enabling faster response and restoration.
Advanced forecasting tools can also help utilities anticipate demand surges during heatwaves and manage supply more effectively.
Integrating Climate Adaptation into Energy Policy
While infrastructure upgrades are essential, climate resilience must also be embedded within policy frameworks. The National Electricity Policy 2026 provides a foundation for this integration, but implementation will be key.
Effective climate-resilient energy policy requires coordination across multiple sectors, including disaster management, urban planning, water resources, and environmental protection.
For instance, ensuring reliable electricity supply during floods requires coordination between power utilities and urban drainage authorities. Similarly, protecting coastal power infrastructure from cyclones involves collaboration with disaster management agencies.
Financing Resilient Infrastructure
Building climate-resilient electricity infrastructure will require substantial investment. However, these investments should be viewed as risk-reduction measures rather than additional costs.
Resilient infrastructure reduces the economic losses associated with power outages, infrastructure damage, and disaster recovery. In the long term, investing in resilience can lower maintenance costs and improve system reliability.
International climate finance, green bonds, and multilateral development funding could play a significant role in supporting these investments.
The Opportunity to Future-Proof India’s Electricity System
India’s electricity sector is entering a new phase of transformation. The country is expanding renewable energy capacity, electrifying transport and industry, and increasing electricity access across rural and urban areas.
At the same time, climate change is reshaping the risk landscape for energy infrastructure. The frequency and intensity of extreme weather events are expected to increase in the coming decades, making resilience a central priority for the power sector.
The National Electricity Policy 2026 provides an opportunity to address these challenges proactively. By integrating climate resilience into planning, design, and investment decisions, India can build an electricity system capable of withstanding future climate shocks.
This approach will not only safeguard energy supply but also strengthen economic stability, protect communities, and support sustainable development.
Conclusion
Climate change is fundamentally altering the environment in which electricity infrastructure operates. Heatwaves, floods, and cyclones are already disrupting power systems in India, highlighting the urgent need for resilient energy infrastructure.
The Draft National Electricity Policy 2026 recognises the importance of building a flexible and resilient grid capable of addressing both renewable integration and climate-related risks. However, translating this vision into reality will require sustained investment, improved planning, and strong institutional coordination.
As India moves toward its development goals and rising energy demand, resilience must become a central pillar of power sector planning. Strengthening transmission networks, climate-proofing generation infrastructure, deploying smart grids, and integrating climate risk assessments into policy decisions will be essential steps.
Ultimately, climate-resilient electricity infrastructure is not just about protecting power systems—it is about safeguarding economic growth, ensuring energy security, and building a sustainable future.
The National Electricity Policy 2026 therefore represents more than a regulatory update. It is an opportunity to future-proof India’s electricity system against escalating climate shocks and ensure that the country’s power infrastructure remains reliable, secure, and resilient in an increasingly uncertain climate.
