2025: The Year India’s Clean Energy Ambition Met Market Reality 

2025 marked a pivotal year in India’s clean energy transition, characterized by the significant achievement of reaching 50% non-fossil power capacity five years ahead of schedule, driven by record solar additions. However, this milestone revealed the next set of complex challenges, as breakneck renewable growth strained grid infrastructure and exposed a critical paradox: while project pipelines for essential battery storage swelled, actual installations slowed dramatically. The market strategically shifted from “plain solar” to tenders for firm, dispatchable power integrated with storage, and the impending EU carbon border tax (CBAM) pressured heavy industries to accelerate decarbonization. Ultimately, the year demonstrated that India has successfully scaled generation but must now master systemic integration, strategic industrial policy, and geoeconomic navigation to secure its sustainable energy future.

2025: The Year India’s Clean Energy Ambition Met Market Reality 

While headlines celebrated India reaching its 50% non-fossil energy capacity target five years early, a deeper look at 2025 reveals a more complex and pivotal chapter in the nation’s climate journey. This was a year where initial ambitions matured into strategic realism, exposing both the remarkable momentum of the transition and the formidable, systemic barriers it now faces. From the paradox of a booming renewables pipeline alongside stalled storage deployments to the looming challenge of European carbon taxes, 2025 crystallized the next set of battles India must win to secure its energy future. 

The Milestone and Its Discontents: Record Growth Meets Grid Constraints 

India’s clean energy achievement in 2025 is undeniable. By October, the country had added 31.2 gigawatts (GW) of non-fossil capacity in the financial year, pushing the total to approximately 259 GW. The third quarter alone saw a record 16 GW of new capacity, with solar power dominating additions and driving total national installed capacity past the 500 GW milestone. 

This explosive growth, however, is straining the very system it aims to transform. A critical challenge emerged in the form of grid integration and transmission bottlenecks. As solar and wind generation surged, the grid experienced a notable increase in curtailment—the wasteful reduction of renewable output—particularly in resource-rich states. This highlights a growing disconnect: generation capacity is sprinting ahead, while the midstream infrastructure of transmission lines and grid management is struggling to keep pace. 

The Storage Paradox: A Booming Pipeline Meets an Installation Slowdown 

Perhaps the most telling contradiction of 2025 was in the energy storage sector, a linchpin for India’s renewable future. While project pipelines swelled to tens of gigawatt-hours, actual installations told a different story. 

• A Sluggish Start: In the first half of 2025, India added a mere 48.8 megawatt-hours (MWh) of new energy storage capacity. This represented a dramatic 74% year-over-year decline from the same period in 2024. 

• A Massive Future Pipeline: In stark contrast, the project pipeline is enormous. As of mid-2025, India had nearly 13.7 GWh of standalone battery storage and over 81 GW of pumped storage in various stages of development. 

This paradox signals a market in transition. The slowdown is likely a temporary pause as the industry digests new mandates and business models. The government has actively shifted its focus, instructing agencies to move from “plain solar” tenders to solar-plus-storage and “firm and dispatchable” renewable energy (FDRE) projects. The economics are following suit: tariffs for renewables-with-storage projects fell 12% year-over-year in Q3 2025, largely due to a 17-25% reduction in battery storage costs. 

The Tender Transformation: From Quantity to Quality 

The shift in India’s renewable energy market is clearly visible in its tender activity. The focus has moved decisively from sheer volume of capacity to the quality and reliability of power. 

• The Rise of Storage-Centric Bids: In Q3 2025, about 40% of all tendered capacity was for standalone energy storage. Furthermore, 70% of new storage tenders required a two-hour discharge duration, indicating a focus on managing peak demand. 

• The Decline of Plain Solar: Reflecting this strategic pivot, awards for basic utility-scale solar photovoltaic (PV) projects have nearly vanished. Only about 2.2 GW of such capacity was awarded in the first three quarters of 2025, down from a peak of 8.2 GW in Q3 2024. 

This evolution marks a critical maturation. Distribution companies and large consumers are no longer satisfied with intermittent power; they are demanding reliable, schedulable clean energy, and the market is restructuring to provide it. 

The Geopolitical Shock: Navigating the EU’s Carbon Border 

Beyond domestic grids and markets, 2025 was the year a major external challenge—the European Union’s **Carbon Border Adjustment Mechanism (CBAM)**—moved from theoretical risk to imminent reality for Indian exporters. 

Scheduled to enter its definitive, chargeable phase in January 2026, CBAM will impose a carbon cost on imports of steel, aluminium, cement, fertilisers, and hydrogen into the EU. For India, a major exporter in sectors like steel and aluminium, this represents both a trade barrier and a catalyst for internal reform. 

The business community’s primary concerns are practical: 

• MRV Challenges: Many exporters, especially small and medium enterprises, lack the technical capacity for the complex monitoring, reporting, and verification (MRV) of emissions required by the EU. 

• Competitiveness at Risk: Without adequate preparation, Indian goods could become less competitive in the crucial European market. 

In response, a strategic consensus is forming. Experts and officials argue that a robust domestic carbon pricing mechanism, such as India’s newly introduced Carbon Credit Trading Scheme (CCTS), could serve a dual purpose. It would help decarbonise Indian industry while potentially allowing exporters to avoid paying the CBAM levy to the EU, as the carbon price would already be paid in India. As Commerce Minister Piyush Goyal stated, “If we collect the tax in India itself, there will be no additional tax”. 

Adaptation and the Road Ahead 

Facing these intertwined challenges, India’s adaptation strategies in 2025 point toward a more integrated, self-reliant, and justice-oriented energy future. 

• Strengthening Domestic Markets: The push for a domestic carbon market is accelerating, driven by both climate goals and the need to pre-empt external trade pressures. 

• Strategic Industrial Policy: Initiatives like the National Green Hydrogen Mission and incentives for green manufacturing parks reflect a turn toward self-reliance in clean technology, aiming to build domestic champions and resilient supply chains. 

• Asserting Climate Justice: On the international stage, India has consistently framed mechanisms like CBAM as undermining the principle of “Common but Differentiated Responsibilities.” The country is coupling its domestic actions with demands for greater climate finance and technology transfer from developed nations, framing equity as a non-negotiable component of global cooperation.

Conclusion: The Maturing of a Green Superpower 

The story of 2025 is not one of simple success or failure. It is the story of a maturing clean energy giant. India has convincingly passed the first test of scaling up renewable capacity. The challenges that dominated the year—grid integration, the storage gap, and geoeconomic pressures—are the next-tier problems of a more advanced stage in the transition. 

The path forward requires moving from building generation projects in isolation to orchestrating a fully integrated, intelligent energy system. It demands coupling industrial policy with climate diplomacy to protect economic interests while accelerating decarbonisation. In navigating these dualities, India’s experience in 2025 offers a crucial lesson for all emerging economies: the energy transition is not just a technological shift, but a profound test of systemic adaptation and strategic foresight. The foundations laid this year will determine whether India’s clean tech story becomes one of sustainable leadership or constrained potential.
