What Lies Beyond Renewable Capacity Addition For India?

Context

Global Wind Day 2026 Conference: India hosted the Global Wind Day 2026 Conference in Goa under the theme “Wind Energy: From Ambition to Acceleration”, signalling a shift in policy focus from renewable energy expansion to renewable energy integration.
Growth in Renewable Capacity: According to the Ministry of New and Renewable Energy (MNRE), India's cumulative renewable energy capacity crossed 282.7 GW by May 2026, including 157 GW of solar power and 56.8 GW of wind power.
India had already achieved the milestone of deriving more than 50% of its installed electricity capacity from non-fossil sources in 2025, five years ahead of its original target.
Building on this achievement, the country has committed to increasing the share of non-fossil capacity to 60% by 2035.
The importance of this transition extends beyond climate policy.

Beyond Climate Objectives: India remains one of the world's fastest-growing energy markets, making energy security, industrial competitiveness, import reduction and sustainable growth increasingly dependent on clean-energy expansion.
A Growing Global Challenge: At the same time, global warming reached approximately 1.37°C in 2025, despite record renewable additions worldwide.
This underscores a crucial reality: the challenge is no longer simply installing renewable capacity.
The next phase will depend on whether renewable electricity can be stored, transmitted and supplied reliably across the economy.

How Has India's Renewable Energy Landscape Changed?

Renewable Expansion to Energy Transition: India's renewable energy growth over the last decade reflects a broader transformation in national energy policy.
What began as an effort to diversify the electricity mix has gradually evolved into a strategy that simultaneously addresses energy security, industrial competitiveness, climate commitments and long-term economic growth.
The share of non-fossil capacity increased from 32.54% in 2014 to 51.93% by December 2025, indicating that clean-energy expansion has moved from the margins of the power sector to its centre.

Year	Total Installed Capacity (GW)	Non-Fossil Capacity (GW)	Share of Non-Fossil Capacity
2014	249.42	81.16	32.54%
2025	513.73	266.79	51.93%

India's installed power capacity more than doubled during this period, while the share of non-fossil sources increased by nearly 20%, reflecting simultaneous expansion and decarbonisation of the electricity sector.
Policy Architecture Enabled Expansion: The transition was supported through a combination of market reforms, infrastructure development and investment incentives.
Competitive bidding guidelines for solar, wind, hybrid and Firm and Dispatchable Renewable Energy (FDRE) projects reduced procurement costs and improved price discovery.
A renewable-energy bidding trajectory of 50 GW annually was introduced to provide long-term investment visibility.
The sector was further supported through 100% Foreign Direct Investment under the automatic route, expansion of transmission infrastructure under the Green Energy Corridor Scheme.
In addition, concessional transmission arrangements that reduced integration costs for renewable projects commissioned during the sector's high-growth phase.
At the consumption end, programmes such as PM Surya Ghar: Muft Bijli Yojana, PM-KUSUM, offshore wind initiatives and the National Green Hydrogen Mission expanded the scope of the transition beyond grid-connected electricity generation.
Fundamentally Different Current Phase: The first phase of India's renewable journey focused on creating generation capacity.
The current phase is increasingly concerned with ensuring that renewable electricity remains reliable, dispatchable and available when required.
This shift is visible in the growing emphasis on energy storage, pumped-storage projects, grid modernisation and domestic manufacturing.
The Government has approved two separate Viability Gap Funding (VGF) schemes supporting 13.22 GWh and 30 GWh of Battery Energy Storage Systems (BESS) capacity respectively.
In parallel, 10 Pumped Storage Projects with a combined capacity of 11,870 MW are under construction to strengthen renewable integration and grid stability.
India's energy transition is therefore no longer centred solely on adding renewable capacity.
It is increasingly focused on building a resilient clean-energy system capable of supporting future economic growth while reducing dependence on fossil fuels.

What Is India Trying to Achieve Through the Energy Transition?

India’s Raised Climate and Energy Ambition: India's renewable energy expansion is guided by a broader vision that combines climate action, energy security and economic development.
The country aims to achieve 500 GW of non-fossil electricity capacity by 2030 and net-zero emissions by 2070 under its Panchamrit commitments.
The updated Nationally Determined Contribution (NDC) further raises ambition by targeting 60% non-fossil installed electricity capacity by 2035, reducing the emissions intensity of GDP by 47% from 2005 levels, and increasing India's carbon sink to 3.5–4 billion tonnes of CO₂ equivalent.
India has also committed to reducing cumulative projected carbon emissions by one billion tonnes by 2030.
These commitments indicate a transition from incremental renewable deployment towards a long-term restructuring of the national energy system.
Planned Scale of Transformation: The scale of India's future ambitions becomes clearer through the projections of the Central Electricity Authority (CEA).
By 2035–36, India is expected to target approximately:

Component	Target
Solar Capacity	509 GW
Wind Capacity	155 GW
Battery Energy Storage Systems (BESS)	80 GW
Pumped Storage Projects (PSP)	94 GW

Together, battery storage and pumped hydro imply a future storage requirement of approximately 174 GW, highlighting that storage will become as important as generation itself.
The transition is also extending beyond electricity.
Under the National Green Hydrogen Mission, India aims to produce 5 million metric tonnes of green hydrogen annually, supporting decarbonisation in hard-to-abate sectors such as fertilisers, refining and heavy industry.
Targets Beyond Climate Commitments: These targets are not merely environmental objectives.
They seek to reduce dependence on imported fuels, strengthen energy security, expand domestic manufacturing and position India as a major participant in emerging clean-energy industries.

What Challenges Could Slow the Next Phase of the Transition?

Renewable Success as Paradox: India's renewable energy expansion has achieved remarkable scale, yet a substantial gap remains between installed capacity and actual electricity generation.
This disparity reflects the fundamental challenge of renewable integration rather than renewable expansion.
The gap exists because electricity demand remains continuous, whereas solar and wind generation remain variable.
India has largely succeeded in building renewable assets; it now faces the more complex task of ensuring that renewable electricity is available when consumers actually need it.

Indicator	Share(As of March 2026)
Renewable Installed Capacity	42.4%
Renewable Share in Electricity Generation	15.8%
Coal Share in Electricity Generation	71.8%

Storage as the Missing Link: The most important bottleneck in the next phase of the transition is the shortage of energy storage infrastructure.
India currently has only about 0.27 GW of installed battery storage capacity, while the Central Electricity Authority projects a requirement of 80 GW of Battery Energy Storage Systems (BESS) by 2035–36.
This implies a nearly 300-fold expansion within a decade.
The significance of this gap lies in the fact that renewable electricity is increasingly being generated at times when it cannot be fully utilised.
Without storage, surplus daytime solar power cannot be shifted to evening peak-demand periods, forcing the system to depend on coal-based generation for balancing and reliability.
Volatile Electricity Prices: The rapid growth of solar power has begun to reshape electricity markets.
Evidence from power exchanges during May 2026 showed near-zero electricity prices on multiple days during peak solar-generation hours, while prices approached the ceiling of ₹10 per unit during evening periods when demand remained high but solar output had fallen sharply.
On 21 May 2026, India's electricity demand reached approximately 270.8 GW, creating a nighttime shortfall of about 2.5 GW despite abundant solar generation earlier in the day.
This emerging duck curve phenomenon demonstrates that electricity abundance during one part of the day can coexist with shortages during another.
The challenge is therefore shifting from electricity generation to electricity timing.
Transmission Networks Bottleneck: Renewable energy creates value only when electricity can reach consumers.
However, several renewable-rich states are facing transmission constraints that restrict the utilisation of available capacity.
For example, Rajasthan has about 23 GW of commissioned renewable capacity but only 18.9 GW of evacuation margin, leaving over 4,000 MW stranded despite being operational.
This highlights the need to expand transmission infrastructure, grid flexibility, and system planning alongside renewable deployment.
Cooling as Energy Transition Challenge: Rising temperatures are driving rapid growth in air-conditioning, refrigeration, and cooling services, making cooling increasingly essential for health, productivity, and economic activity.
This creates a paradox: climate change is increasing electricity demand even as it necessitates a clean-energy transition.
Without major efficiency gains, cooling demand could outpace renewable-energy expansion.
The challenge is further heightened by India's commitment under the Kigali Amendment to freeze hydrofluorocarbons (HFCs) consumption from 2028 and shift to climate-friendly cooling technologies.
Replacing Energy Dependence with Technology Dependence: While renewable energy reduces dependence on imported fossil fuels, it can create new strategic vulnerabilities.
Despite progress in domestic manufacturing, India still imports about 75–80% of its lithium-ion cell requirements, creating reliance on external supply chains.
As a result, energy security is increasingly linked to technology security, critical minerals, manufacturing competitiveness, and supply-chain resilience.
Uneven Renewable Adoption: India's renewable-energy transition remains uneven.
The top five states–Gujarat, Maharashtra, Uttar Pradesh, Kerala, and Rajasthan–account for nearly 70% of rooftop solar installations, reflecting significant regional concentration.
A key reason is that heavily subsidised or free electricity in some states reduces incentives to adopt rooftop solar. Bridging this gap will require better alignment between state electricity policies and national renewable-energy goals.

What Should India Do Next?

Move Beyond Capacity Addition: India has largely succeeded in expanding renewable capacity.
The next phase must focus on system integration, with equal emphasis on generation, storage, transmission, and reliability.
Success should increasingly be measured by the share of actual clean electricity generation, not installed capacity alone.
Make Storage Core Infrastructure: Energy storage must become a foundational part of the power system.
The Energy Storage Obligation (ESO) framework, falling battery costs, and rising storage requirements make accelerated deployment through co-location mandates, long-term procurement, and market incentives essential.
Modernise Grid Management: A renewable-rich grid requires smarter operations.
Investments in AI-based forecasting, real-time monitoring, and advanced scheduling can improve grid efficiency and better manage variable renewable generation.
Integrate Wind and Solar: India should maximise the complementary strengths of wind and solar energy.
Hybrid projects, Round-the-Clock (RTC) renewable models, and storage-linked systems can improve reliability while reducing balancing costs.
Reduce Technology Dependence: Energy security must extend beyond fossil fuels.
Strengthening domestic manufacturing through the Production Linked Incentive Scheme (PLI Scheme), Approved List of Models and Manufacturers (ALMM), battery production, and critical-mineral processing can reduce reliance on imported clean-energy technologies.
Decarbonise Cooling: Cooling policy should be integrated with energy policy.
Greater adoption of energy-efficient appliances, low-GWP refrigerants, climate-responsive urban planning, and better building design can moderate future electricity demand growth.
Accelerate Distributed Renewable Energy: Consumers should increasingly become energy producers.
Expanding rooftop solar and shifting support from electricity-consumption subsidies to renewable asset creation can improve energy resilience and reduce long-term fiscal burdens.
Build a Renewable Energy System: The next phase of India's transition is not merely about adding capacity but about creating a reliable, affordable, and resilient clean-electricity system supported by storage, transmission, manufacturing, and strong institutions.
The Ultimate Test: India has demonstrated that rapid renewable expansion is possible.
The real challenge now is transforming renewable capacity into a system that simultaneously advances energy security, economic growth, and climate goals.
