India's Power Capacity to Hit 1,121 GW by 2036, Renewables to Lead

A New Era for India's Power Sector

India is poised for a significant expansion of its power generation capacity, projected to reach 1,121 gigawatts (GW) by the financial year 2035-36. A new report from the Central Electricity Authority (CEA), released at the Bharat Electricity Summit in New Delhi, outlines a strategic shift where non-fossil fuel sources are expected to constitute nearly 70% of this total capacity. This ambitious roadmap underscores the nation's accelerated transition towards cleaner energy while ensuring a reliable power supply for its growing economy.

The Future Energy Mix

The CEA's National Generation Adequacy Plan details a diversified energy portfolio for the next decade. Solar power is set to lead this transformation, accounting for 509 GW of the total projected capacity. It will be followed by coal, which will remain a significant contributor at 315 GW. Other key sources include wind power at 155 GW, large hydro projects at 77 GW, and nuclear power at 22 GW. This planned capacity addition aligns with India's target of achieving 500 GW of non-fossil fuel capacity by 2030.

Meeting Surging Demand

This capacity expansion is driven by robust electricity demand projections. The report anticipates that peak electricity demand will grow at a compound annual growth rate (CAGR) of 5.58%, reaching 459 GW by 2035-36. The total electricity requirement is projected to grow even faster, at a CAGR of 6.41%, to 3,365 billion units during the same period. This growth is fueled by economic expansion, increased electrification, and the rise of new sectors like electric vehicles and green hydrogen.

Milestones and Recent Progress

India's power sector has already achieved significant milestones. As of January 31, 2026, the country's installed capacity stood at 520.5 GW. Notably, India surpassed its target of having 50% of its installed capacity from non-fossil fuel sources in 2025, five years ahead of its 2030 commitment under the Paris Agreement. The current financial year (2025-26) has seen a record addition of 52.5 GW of capacity as of January, with renewable energy sources contributing about 43 GW of this total.

The Crucial Role of Energy Storage

To manage the intermittency of renewable sources like solar and wind, the plan envisages a substantial increase in energy storage capacity. A total of 174 GW of storage is planned, which includes 80 GW from battery energy storage systems (BESS) and 94 GW from pumped storage projects. This infrastructure is critical for ensuring grid stability and providing a reliable, round-the-clock power supply.

Coal's Continued Importance

Despite the rapid growth in renewables, the CEA report acknowledges that coal will continue to play a major role in India's energy security. Coal-based generation is considered a vital source of firm, dispatchable power that can operate 24x7, providing the baseload stability required to support the grid as more variable renewable sources are integrated.

Investment and Overcoming Challenges

The path to achieving these targets requires substantial investment. Estimates suggest that India will need around $100 billion (approximately ₹30.54 lakh crore) by 2030 to fund renewable power generation, storage solutions, grid infrastructure, and manufacturing. The Economic Survey 2026 highlighted several challenges that need to be addressed, including high capital costs for renewable projects, delays in land acquisition, and ensuring adequate grid availability to evacuate power from new projects.

A Forward-Looking Strategy

India's energy strategy reflects a clear commitment to a sustainable future, balancing environmental goals with economic development. The government's stable policies and transparent markets have attracted significant private sector participation. By focusing on a mix of solar, wind, hydro, and nuclear power, supported by essential storage systems and a stable coal fleet, India is charting a course to meet its future energy needs securely and sustainably. The successful implementation of this plan will be crucial for achieving the nation's long-term goal of net-zero emissions by 2070.
