Context:
India has recorded a major expansion in its power sector by adding 52,537 MW of electricity generation capacity up to January 31 of the current financial year. A large share of this addition has come from renewable energy, indicating progress towards cleaner growth and energy transition.
Key Highlights:
Scale of Capacity Addition
• India added 52,537 MW of new generation capacity during the current financial year.
• This represents an increase of more than 11% in the country’s total installed capacity.
• Total installed power generation capacity now stands at 5,20,510.95 MW.
Dominant Role of Renewables
• Renewable energy contributed 39,657 MW to the total addition.
• Solar energy alone added 34,955 MW, while wind energy added 4,613 MW.
• Renewables now account for nearly 50.5% of India’s total installed power capacity at 2,63,189.33 MW.
Energy Mix in India
• Fossil fuel-based power still constitutes around 48% of total installed capacity at 2,48,541.62 MW.
• Nuclear energy contributes about 1.6%, amounting to 8,780 MW.
• The current year’s capacity addition has surpassed the previous record of 34,054 MW in FY 2024–25.
Significance of the Trend
• The figures reflect accelerating growth in renewable energy deployment, especially solar power.
• They also indicate progress towards India’s commitments on energy transition, climate action, and energy security.
Relevant Prelims Points:
- Megawatt (MW) is a unit of power equal to one million watts.
• Installed Capacity means the maximum electricity generation capability of a plant or system under ideal conditions.
• Renewable Energy includes sources such as solar, wind, hydropower, biomass, and small hydro, which are replenished naturally.
• Solar energy has emerged as the largest contributor to new renewable capacity addition in India.
• Installed capacity is different from actual electricity generation, which depends on factors such as fuel supply, sunlight, wind conditions, and plant load factor.
Relevant Mains Points:
Why this Growth Matters
• Strengthens energy security by diversifying the power mix.
• Reduces long-term dependence on imported fossil fuels.
• Helps India meet its climate commitments and expand non-fossil fuel capacity.
• Supports industrialisation, urbanisation, and rising electricity demand.
• Promotes growth of sunrise sectors such as solar manufacturing, storage, transmission, and green jobs.
Concerns and Limitations
• High installed renewable capacity does not automatically ensure round-the-clock power supply.
• Need for stronger grid integration, energy storage, and balancing mechanisms.
• Fossil fuels still retain a major role in ensuring baseload power.
• Land acquisition, transmission bottlenecks, and DISCOM financial stress remain concerns.
Way Forward
• Invest in battery storage, pumped hydro, and smart grids.
• Strengthen transmission infrastructure for renewable-rich regions.
• Improve DISCOM reforms and power sector financial health.
• Promote domestic manufacturing under clean energy value chains.
• Balance renewable expansion with grid reliability and affordability.
