India is steadily building the foundation for a five-fold expansion in its power sector over the next 15 years, driven by rising demand, renewable energy adoption, and long-term infrastructure planning.
Installed Capacity on a Strong Growth Path
India’s installed power capacity has reached ~510 GW as of November 2025, with nearly 100 GW added in just the last three years. Annual capacity additions are now running at ~50–55 GW, largely led by solar energy, with consistent contributions from wind and hydro.
To reach the projected ~900 GW by 2030–32, India will need to sustain annual additions of 60–70 GW. Given the current momentum, this target appears well within reach.
Rapid Shift in the Generation Mix
The transformation of India’s power sector is not just about scale, but also about composition:
- Solar share has surged to ~26%, up from ~15% three years ago
- Wind remains stable at around ~10%
- Thermal power’s share has declined from ~58% to ~48%, reflecting aggressive renewable additions
Importantly, this capacity is not merely for optics. Plant Load Factors (PLF) and Capacity Utilisation Factors (CUF) have improved across technologies, translating into higher actual power generation to meet rising demand.

The Bigger Demand Story
India’s per-capita electricity consumption currently stands at ~1,250 units, significantly lower than:
- China: ~6,500 units
- United States: ~12,900 units
With total generation of 1,800–1,900 billion units and a population of ~146 crore, the gap highlights immense headroom for growth.
Even under a conservative assumption of 6,000 units per capita by 2040, and a population exceeding 160 crore, India’s electricity generation would need to rise to ~9,600 billion units. This implies a ~12% CAGR over the next 15 years.
To support this demand, India would require over 2,500 GW of installed capacity by 2040—more than 5x current levels—excluding additional renewable capacity needed for green hydrogen production.
Multi-Year Investment Opportunity
A 5x expansion in power generation unlocks long-term opportunities across:
- Transmission & Distribution (T&D)
- Substations and grid infrastructure
- Power equipment and capital goods
Despite often being labelled an “old economy” sector, power will remain the backbone of a Viksit Bharat by 2047, requiring sustained and large-scale investments.
