Introduction

Energy security — the uninterrupted availability of energy at an affordable price — is a strategic imperative for India's economic growth and geopolitical sovereignty. India is the world's third-largest energy consumer (after China and the USA), with energy demand growing rapidly alongside industrialisation and rising living standards.

Key tension: India needs cheap energy for development while simultaneously committed to climate targets under the Paris Agreement. Managing this transition is the central energy policy challenge.


India's Energy Profile

Indicator Data
Global rank in energy consumption 3rd largest
Oil import dependence ~85% of crude oil requirements imported
Installed electricity capacity (total) Over 500 GW (as of early 2025, including all sources)
Non-fossil capacity 250 GW (as of September 2025)
Coal share in electricity generation ~69% (FY 2024-25)
Primary energy mix Coal dominant (~55% of primary energy)
Per capita energy consumption Below global average

India achieved 50% non-fossil capacity (as a share of total installed capacity) in June 2025 — five years ahead of the NDC target.


Oil and Gas Sector

Import Dependence and Vulnerability

India imports approximately 85% of its crude oil requirements, making the economy vulnerable to global price shocks. Over 60% of oil imports come from the Middle East (Gulf), creating geographic concentration risk.

Major oil import sources: Iraq, Saudi Arabia, Russia (increased sharply post-2022 Ukraine war), UAE, USA.

Upstream Sector (Exploration & Production)

Company Role
ONGC (Oil & Natural Gas Corporation) India's largest oil and gas E&P company; Navratna PSU under MoPNG
OIL India Ltd Second largest E&P PSU; focused on North-East India
ONGC Videsh Ltd (OVL) Overseas E&P arm of ONGC

Downstream Sector (Refining & Distribution)

Company Role
Indian Oil Corporation (IOC) Largest company by revenue; runs 11 refineries
Bharat Petroleum (BPCL) Second largest; Kochi, Mumbai, Bina refineries
Hindustan Petroleum (HPCL) Third largest; Mumbai, Vizag refineries
Reliance Industries Operates world's largest single-location refinery complex at Jamnagar

Challenges in Oil & Gas

  • High fiscal subsidy burden on LPG and kerosene (though direct benefit transfer reformed LPG subsidies)
  • Gas infrastructure underdeveloped; gas share in primary energy ~6% vs world average ~24%
  • ONGC declining production from ageing fields; difficult to attract FDI for deep-water exploration
  • City Gas Distribution (CGD) network being expanded under PNGRB

Strategic Petroleum Reserve (SPR)

India maintains emergency crude oil reserves to cushion against supply disruptions.

Location State Capacity
Visakhapatnam Andhra Pradesh 1.33 MMT
Mangaluru Karnataka 1.50 MMT
Padur (Udupi district) Karnataka 2.50 MMT
Total 5.33 MMT
  • Managed by ISPRL (Indian Strategic Petroleum Reserves Limited), a SPV under MoPNG
  • Total SPR provides approximately 9.5 days of consumption cover
  • India also has commercial stocks — combined total gives ~74 days
  • International Energy Agency (IEA) recommendation: 90 days' cover (India is now an IEA associate)
  • Phase II expansion: additional locations planned but stalled due to funding constraints

Coal Sector

Dominance and Scale

Coal remains India's dominant energy source, accounting for about 69% of electricity generation and ~55% of primary energy. India crossed 1 billion tonnes of coal production in FY 2024-25 for the second consecutive year, reaching 1,047.57 MT.

Metric Data
Coal production (FY 2024-25) 1,047.57 MT (provisional)
Coal India Ltd share ~80% of domestic production
Coal share in electricity generation ~69%
Target coal generation by 2030 Projected to fall to ~60%

Coal India Limited (CIL)

  • World's largest coal producer
  • Navratna PSU under Ministry of Coal
  • Has 7 wholly-owned coal mining subsidiaries
  • CIL is also setting up 3,000 MW of renewable energy for its own mining operations

The Coal Import Paradox

Despite being the 2nd largest coal producer, India imports coal for:

  • Power plants (due to high ash content of domestic coal for super-critical plants)
  • Steel sector (coking coal — India has limited coking coal reserves)
  • Coastal power plants (imported coal cheaper than inland freight for domestic coal)

Just Energy Transition

  • India committed to transition away from coal as part of COP26 commitments (with caveats)
  • JETP (Just Energy Transition Partnership): India in discussions; no formal deal signed as of March 2026 (unlike South Africa, Indonesia, Vietnam which signed)
  • Key concern: coal employs over 2 million workers directly and millions indirectly; abrupt phase-down risks social disruption
  • Planned Coal Mines Closure Policy and just transition funds being discussed

Renewable Energy

500 GW Target by 2030

India's NDC commits to 500 GW of installed non-fossil fuel capacity (RE + nuclear) by 2030.

Milestone Status
Non-fossil capacity (Sept 2025) 250 GW
50% non-fossil capacity target Achieved June 2025 — 5 years early
RE capacity H1 2025 addition 22 GW (56% year-on-year growth)
Solar capacity (Feb 2025) ~102.57 GW
Total power capacity (early 2025) Over 5.05 lakh MW (505 GW)
