What is approximately the total installed power generation capacity of India…

Concept: "Installed power generation capacity" is the total electricity-generating capacity (in MW/GW) that India's power plants can produce, aggregated across all sources - thermal, hydro, nuclear, and renewable - and compiled by the Central Electricity Authority (CEA) under the Ministry of Power as of a stated date.

Application: As per the CEA's official installed-capacity report and the Ministry of Power's Annual Report, India's total installed power generation capacity stood at approximately 475 GW (475,211.80 MW) as on 31 March 2025.

Cross-check: This is consistent with India's capacity growth trend - from about 249 GW in 2014, crossing roughly 425 GW by October 2023, about 457 GW by November 2024, and further past 500 GW by September 2025. A figure of approximately 475 GW at the close of FY 2024-25 (31 March 2025) fits this trajectory.

The other figures correspond to distinct milestones, not the 31 March 2025 total:

• 500 GW is the non-fossil-fuel-based installed capacity target India committed to for 2030 under its NDC at COP26 (2021), a separate future target rather than the 31 March 2025 total.

• 450 GW was an earlier (2021) MNRE target specifically for renewable-energy installed capacity by 2030, not the 31 March 2025 total across all sources.

• 420 GW is close to India's total installed capacity level around late 2023, a figure the country had already grown past well before 31 March 2025.
