The Lede
Experts associated with the Council on Energy, Environment and Water (CEEW) have provided a comprehensive review of India's performance in the renewable energy (RE) sector and its climate action efforts throughout 2025. The year marked significant advancements, particularly in expanding renewable power generation capacity. However, critical challenges persist, notably the urgent need for enhanced energy storage and grid flexibility to fully leverage these gains and address the growing impacts of climate change.
The assessment highlights a year of record-breaking achievements alongside stark environmental realities. While India solidified its position as a global leader in solar and wind power, the nation also grappled with an unprecedented frequency of extreme weather events, underscoring the immediate need for robust adaptation strategies and resilient infrastructure.
Renewable Energy Milestones
- India achieved a remarkable milestone by bringing a record 45 gigawatts (GW) of renewable energy capacity online by November 2025, demonstrating substantial growth despite hurdles like land acquisition and grid integration.
- The growing dominance of renewables was evident in July, when renewable sources collectively met more than half of the country's electricity needs on a single day.
- The single biggest catalyst for this expansion was the rapidly falling cost of renewable technologies, making them increasingly competitive and attractive.
- Renewables integrated with battery storage are now emerging as the cheapest form of reliable, firm power available, significantly undercutting the fixed costs associated with new coal power plants.
The Critical Storage Bottleneck
- Despite its global standing in solar and wind power, India has been slow to develop operational battery energy storage systems (BESS). This lag represents a significant missed opportunity.
- There is an immediate imperative to accelerate the adoption of storage solutions and enhance grid flexibility to capitalize on low-cost renewable energy. This is vital for ensuring affordable and dependable power supply for all citizens.
- Projections indicate that grid flexibility requirements will need to increase at least fivefold over the next five years to accommodate the growing RE penetration.
- While India has a substantial pipeline with 68 GWh of awarded BESS capacities, only nearly 10 GWh are currently under construction, highlighting the slow pace of actual deployment.
Climate Action and Policy
- Adaptation to the escalating impacts of climate change was elevated on the national agenda, with the finalization of contours for India's national adaptation plan during 2025.
- This focus on adaptation did not come at the expense of mitigation efforts; India's renewable energy capacity continued its substantial upward trajectory.
- A significant development was the intensified debate surrounding domestic compliance carbon markets, as stakeholders worked to understand their structure and implications following the notification of firm-specific mitigation targets.
- Indian businesses also faced complexities in comprehending the administrative procedures and economic consequences of Europe's proposed border carbon tax.
- On the international stage, India maintained pressure on developed nations, advocating strongly for climate finance and opposing unilateral trade measures that could disadvantage developing economies.
Facing Environmental Extremes
- The year 2025 was characterized by an alarming frequency of extreme weather events, occurring almost every other day and signaling a definitive shift towards a "new normal" of climate change impacts.
- These events included a severe heatwave in Mumbai in February, devastating floods across Punjab, and destructive cloudbursts in Himachal Pradesh, all of which resulted in significant human casualties and substantial economic losses.
- Statistics reveal that over 80 percent of India's population resides in districts highly vulnerable to extreme hydro-meteorological disasters.
- Similar extreme climate impacts were observed globally, with over 800 cities in Europe reporting temperatures significantly above average, and Cyclone Senyar causing an estimated $20 billion in economic losses across Southeast Asia.
Impact
- The news highlights the critical need for investment and policy focus on energy storage and grid modernization, potentially creating opportunities for companies in this space. It also signals ongoing risks from climate change for businesses and populations. The successful integration of renewables and storage is crucial for India's energy security and economic growth, while climate resilience measures are vital for protecting lives and assets.

Difficult Terms Explained
- Renewable Energy (RE): Energy derived from natural sources that are replenished at a higher rate than they are consumed, such as solar, wind, and hydro.
- Gigawatts (GW): A unit of power equal to one billion watts, commonly used to measure the capacity of electricity generation plants.
- Battery Energy Storage Systems (BESS): Systems that store electrical energy generated from sources like solar or wind for later use, helping to stabilize the grid.
- Grid Flexibility: The ability of an electricity grid to adapt to changes in supply and demand, essential for integrating variable renewable sources.
- Mitigation: Actions taken to reduce the extent of climate change, primarily by lowering greenhouse gas emissions.
- Adaptation: Adjusting to actual or expected future climate conditions and their effects to moderate harm or exploit beneficial opportunities.
- Compliance Carbon Markets: Systems where companies must reduce emissions to meet a regulatory cap and can trade emission allowances.
- Unilateral Trade Measures: Trade policies enacted by one country without the agreement of other countries, often used to address issues like carbon emissions.
- Hydro-met Disasters: Extreme weather events such as floods, droughts, heatwaves, and storms, often linked to hydrological and meteorological phenomena.
