Context : The Cabinet has approved significant green energy investments, raising NTPC's limit to Rs 20,000 crore and allowing NLC India to invest Rs 7,000 crore. These decisions aim to boost renewable energy capacity, with NTPC targeting 60GW by 2032.
Introduction
India is undergoing a massive energy transformation, shifting from fossil fuels to renewable sources at an unprecedented pace. With ambitious targets and innovative policies, the country is emerging as a global leader in clean energy. This article examines India’s renewable energy landscape, supported by real-world examples, key challenges, government initiatives, and future strategies.
India’s Energy Mix: Current Status & Growth
- India’s total installed power capacity reached 476 GW as of June 2025.
- Power shortages dropped from 4.2% in 2013–14 to 0.1% in 2024–25.
- Over 2.8 crore households were electrified, per capita electricity consumption increased by 45.8%.
- Non-fossil fuel sources now contribute 235.7 GW (49%) of total capacity, including 226.9 GW renewable and 8.8 GW nuclear.
- Thermal power remains dominant, accounting for 240 GW or 50.52% of installed capacity.
As per IRENA RE Statistics 2025, India ranks 4th globally in Renewable Energy Installed Capacity, 4th in Wind Power, and 3rd in Solar Power capacity.
Why Renewable Energy is Crucial for India?
1. Energy Security & Reduced Imports
- Example: Solar and wind energy helped reduce coal imports by ~38 million tonnes in FY23, saving ~$2.5 billion.
- Goal: Cut fossil fuel imports by $100 billion/year by 2030.
2. Climate Change & Pollution Control
- Impact: Renewables helped India avoid ~300 million tonnes of CO₂ emissions annually.
- Case Study: Delhi’s Indira Gandhi International Airport runs entirely on solar and hydropower, cutting 200,000 tonnes of CO₂/year.
3. Rural Electrification & Job Creation
- Example: Solar microgrids in Bihar & Uttar Pradesh power 5 million homes, reducing kerosene dependency.
- Employment: The sector employs ~400,000 people; target of 3 million jobs by 2030.
Key Challenges in Scaling Up Renewables
1. Dependence on Imports & Critical Minerals
- Issue: 80% of solar modules imported from China.
- Example: India’s PLI scheme for solar manufacturing aims to cut reliance by boosting domestic production.
2. Grid Integration & Storage Limitations
- Challenge: Only ~4 GW/8 GWh of battery storage installed.
- Case Study: SECI’s 1 GW Battery Storage Tender (2023) seeks to stabilize renewable supply.
3. Land Acquisition & Environmental Concerns
- Example: Great Indian Bustard (GIB) vs. Solar Farms – Supreme Court ordered underground transmission lines to protect endangered birds.
4. Financing & Policy Bottlenecks
- Issue: DISCOM financial health delays payments to renewable producers.
- Solution: Late Payment Surcharge (LPS) Scheme to clear ₹1.4 lakh crore dues.
Government Initiatives Driving Renewable Growth
1. National Solar Mission (500 GW by 2030)
- Example: Kurnool Ultra Mega Solar Park (1 GW) powers ~700,000 homes.
2. PM-KUSUM Scheme (Solar for Farmers)
- Impact: 3 lakh solar pumps installed, reducing diesel use.
3. Green Hydrogen Mission (5 MMT by 2030)
- Case Study: Reliance’s 5 GW Green Hydrogen Plant in Gujarat (Largest in Asia).
4. International Solar Alliance (ISA)
- Global Impact: 120+ countries collaborating on solar projects.
Way Forward: Strategies for a Sustainable Future
1. Boost Domestic Manufacturing
- Example: Adani Solar’s 4 GW factory – India’s largest integrated solar unit.
2. Expand Energy Storage Solutions
- Initiative: Pumped Hydro Storage (PHS) projects (e.g., 10 GW planned in Himachal Pradesh).
3. Strengthen Grid Infrastructure
- Case Study: Green Energy Corridors (₹40,000 cr project for renewable transmission).
4. Encourage Private Investments
- Example: Amazon & Google investing in Indian solar/wind farms for carbon-neutral operations.
5. R&D in Emerging Technologies
- Innovation: Floating Solar Plants (e.g., 600 MW Omkareshwar Dam project).
The International Solar Alliance (ISA), launched in 2015 by India and France at COP21, is the first treaty-based intergovernmental organisation headquartered in India. With a 2020 amendment, all UN member states became eligible to join the ISA. As of March 2025, 122 countries have signed the ISA Framework Agreement, and 105 have ratified it.
Prime Minister of India at the First Assembly of the International Solar Alliance (ISA) in Oct 2018, had called for One Sun – One World – One Grid (OSOWOG). It is a global initiative to create a transnational solar power grid based on the idea that “The Sun Never Sets.” The International Solar Alliance (ISA) is leading its implementation. Phase-I of the study has been completed and approved, and further work is in progress. A task force was also set up in 2021 to explore grid interconnections with regions including South Asia, Middle East, Africa, and Europe.
Conclusion: India’s Green Energy Ambition
India is on track to achieve 50% renewable energy by 2030, a critical milestone for energy independence and climate action. While challenges like import dependency and grid stability persist, strong policies, private investments, and technological advancements are paving the way for a sustainable future.
Final Thought:
"India’s renewable energy journey isn’t just about megawatts; it’s about securing a cleaner, self-reliant future for generations."
