Surpassing the Non-Fossil Fuel Capacity Goal Ahead of Time: India has already achieved its COP26 commitment to have 50% of its installed electricity generation capacity from non-fossil fuel sources, showcasing exceptional policy effectiveness and rapid execution.
This early achievement demonstrates a decoupling of energy growth from carbon-intensive sources, providing strong global confidence in India’s net-zero 2070 pathway and enabling further ambitious clean energy targets.
As of September 2025, the installed non-fossil capacity has crossed 250 GW, representing over 50% of the country’s total power capacity, successfully meeting the 2030 target five years early.
Global Leadership in Solar Capacity and Manufacturing Growth: Solar energy is the central pillar of the energy transition, and India is asserting itself as a global solar powerhouse through massive capacity addition and domestic manufacturing support.
The success of national schemes and low tariffs, driven by reverse auctions, makes solar the most cost-competitive and rapidly deployable source of new power generation, reducing the need for imported fuel.
India’s cumulative solar capacity has reached around 130 GW (as of October 2025), and domestic solar module manufacturing capacity has nearly doubled from 38 GW to 74 GW in FY 2024–25, driven by the Production Linked Incentive (PLI) scheme.
Launch of the National Green Hydrogen Mission (NGHM): The launch of the National Green Hydrogen Mission marks India’s aggressive move to decarbonize hard-to-abate sectors like fertilizers, refining, and heavy industries, shifting the focus beyond just the power sector.
The mission establishes a comprehensive ecosystem for green hydrogen production and utilization, positioning India as a potential global hub for green hydrogen export, which is crucial for long-term energy security.
The mission targets developing a Green Hydrogen production capacity of at least 5 Million Metric Tonnes (MMT) per annum by 2030, which is expected to attract over ₹8 lakh crore in total investments.
Decentralization of Renewable Energy through Rooftop Solar Schemes: A major shift is the focus on democratizing power generation, moving beyond large utility-scale projects to empower households and farmers as producers of clean energy.
The widespread adoption of decentralized solar, particularly rooftop and agricultural pumping, significantly reduces transmission losses, enhances grid resilience, and directly impacts consumer’s electricity bills.
The PM Surya Ghar: Muft Bijli Yojana, launched in February 2024 with a ₹75,021 crore outlay, targets rooftop solar installations in one crore households.
Financial Incentives for Energy Storage: Recognizing the intermittency challenge of solar and wind, the government has prioritized energy storage, including Battery Energy Storage Systems (BESS) and pumped storage projects (PSP), to achieve a Round-the-Clock (RTC) reliable power supply.
The introduction of targeted financial mechanisms is essential to bridge the current cost gap, making storage projects viable and facilitating high penetration of variable renewables into the grid.
The Cabinet has approved a Viability Gap Funding (VGF) scheme for BESS, in September 2023 with an initial allocation to support the development of 4,000 MWh of BESS projects.
