India’s total primary energy supply (TPES) increased to 39,055 Petajoules in 2024–25, up from 37,936 Petajoules in the previous year, the government informed Parliament. The renewable energy potential also more than doubled to 4,704,043 MW as of March 2025, reflecting the country’s accelerating clean energy transition.
Key Highlights
- India’s total primary energy supply rose to 39,055 Petajoules in FY25.
- Renewable energy potential increased to 4,704,043 MW by March 2025.
- MoSPI has reduced survey data release timelines using digital technologies and AI-enabled tools.
- The government has revised the base years for GDP, IIP and CPI to better reflect the evolving economy.
New Delhi, July 22: India’s total primary energy supply (TPES) reached an estimated 39,055 Petajoules during 2024–25, compared with 37,936 Petajoules in 2023–24, according to information shared by the government in the Lok Sabha on Wednesday.
In a written reply, Minister of State (Independent Charge) for Statistics and Programme Implementation Rao Inderjit Singh said the country’s total renewable energy potential was estimated at 4,704,043 MW as of March 2025, more than double the 2,109,655 MW estimated as of March 31, 2024.
The minister explained that one Petajoule (PJ) equals 10¹⁵ joules, or approximately 278 gigawatt-hours (GWh) of energy, making it a standard unit for measuring large-scale national energy supply.
Highlighting improvements in official statistical systems, Singh said the Ministry of Statistics and Programme Implementation (MoSPI) has strengthened data collection through digital platforms, including Computer Assisted Personal Interview (CAPI) and the e-SIGMA system. These platforms incorporate real-time validation checks, AI-enabled chatbots, multilingual interfaces and continuous data monitoring, improving the accuracy and reliability of official statistics.
The minister said the use of digital technologies has significantly reduced the time taken to release survey results. Data that previously took 8–9 months to publish is now released much faster. Annual survey results are published within 90–120 days, quarterly surveys within 45–60 days, and monthly surveys within 15–30 days after completion.
To promote transparency and evidence-based policymaking, MoSPI has also revamped its Microdata Portal, making anonymised unit-level survey data available to researchers, policymakers and other stakeholders for analysis and research.
Singh further informed Parliament that the government has completed comprehensive base year revisions for key macroeconomic indicators to better reflect India’s evolving economic structure and align with international statistical standards. The base year for Gross Domestic Product (GDP) has been revised from 2011–12 to 2022–23, the Index of Industrial Production (IIP) base year has also been updated to 2022–23, while the Consumer Price Index (CPI) base has been changed from 2012=100 to 2024=100.
The latest government data highlights India’s growing energy demand alongside a rapid expansion in renewable energy potential. Coupled with modernisation of statistical systems and updates to key economic indicators, these measures are expected to improve policy planning, strengthen transparency and support India’s long-term economic and energy transition goals.
