India's Clean Energy Milestone Achieved

India has reached a significant milestone in its energy transition, achieving 50% of its installed electricity capacity from non-fossil fuel sources, five years ahead of the target outlined in its Nationally Determined Contributions (NDCs) under the Paris Agreement.

Key Highlights

• Milestone Achievement: As of June 30, 2025, India’s installed electricity capacity totals around 484 gigawatts, with 50% sourced from non-fossil fuels, marking a major shift in energy policy and commitment to climate action, as stated by Pralhad Joshi, Union Minister for New and Renewable Energy.

• Historical Context: In 2014, renewable energy sources constituted approximately 30% of India’s total electricity capacity. This share has seen substantial growth, emphasizing the nation’s commitment towards sustainable development.

• Electricity Generation from Clean Sources: Despite the increase in installed capacity reaching 50%, the actual share of clean energy generation stands below 30%. The share of electricity generated from non-fossil sources increased marginally from 17% in 2014-15 to about 28% in the period of April 2024 to May 2025.

• Annual Production Growth: Clean energy production surged from 190 billion units in 2014-15 to 460 billion units in the 2024-25 period, indicating a notable rise in renewable energy output in line with the increasing capacity.

• Capacity Utilisation Factor (CUF): A critical factor limiting effective utilization of clean energy is the lower CUF associated with renewable sources compared to traditional energy sources like coal. Current CUF values stand at approximately 20% for solar and 25-30% for wind, contrasted with coal’s 60% and nuclear’s 80%.

• Base Load Demand: Approximately 75% of India’s energy mix is supplied by coal, meeting base load demand. Although there is rising utilisation of solar energy, its production primarily occurs during the day, leading to potential shortfalls in the evening when demand spikes.

• Recommendations for Improvement: Experts advocate for the introduction of differential tariffs for electricity, similar to previous telecommunications models, allowing for cheaper night-time rates to encourage energy use during off-peak hours. Implementing this would require enhanced grid flexibility and advancements in battery storage technologies.

• Future Framework: The development of hybrid power projects integrating solar, wind, hydro, and storage elements is recommended to meet India’s growing energy requirements. Such hybrids would allow for energy storage and release during peak demand, particularly during evening hours. However, challenges remain, including land-aggregation issues, ineffective transmission planning, and high costs associated with storage components.

Conclusion

India's progress towards achieving a substantial part of its electricity generation from non-fossil fuel sources demonstrates a shift towards a sustainable energy framework. While the installed capacity has significantly advanced, actual electricity generation still requires improvement in utilization strategies and the incorporation of innovative technologies to maximize the potential of renewable energy.
