Coal India Limited
India's state-owned coal miner, founded in 1975 and responsible for roughly 80% of the country's coal output through 322 mines — a Maharatna-status company now expanding into other minerals like iron ore.

Overview and History
Coal India Limited was incorporated on November 1, 1975, following the Indian government's nationalisation of the country's coal mines in the early 1970s — a move driven by concerns over unsafe and exploitative practices in the then-fragmented, privately run coal sector, and by the strategic need to guarantee reliable fuel supply for a power and steel sector the government was actively trying to expand. Consolidating hundreds of individual mines under a single state-owned company gave India centralised control over its most important domestic energy resource at a time when coal was, and largely still is, the backbone of the country's electricity generation.
CIL now holds Maharatna status, the highest tier of operational and financial autonomy the Indian government grants to a central public sector enterprise, a distinction shared with only a handful of India's largest state-owned companies. That status reflects both CIL's scale — it is the world's largest coal producer by volume — and its consistent profitability, a combination that is unusual among public sector coal miners globally.
Operations and Subsidiaries
CIL doesn't mine coal directly under its own name so much as coordinate a group of eleven operating subsidiaries, each responsible for a different coalfield region of India — among them Mahanadi Coalfields, its largest producer, alongside Eastern Coalfields, Bharat Coking Coal, South Eastern Coalfields, Western Coalfields, Central Coalfields and Northern Coalfields. Together, these subsidiaries run 322 mines across eight Indian states, split between 171 opencast mines, 138 underground mines and 13 mixed operations, accounting for well over 80% of India's total domestic coal production.
CIL has also taken its first steps outside India, holding an international coal mining subsidiary in Mozambique — a modest but notable departure for a company whose entire operating history had, until recently, been confined to Indian coalfields.
Diversification Beyond Coal
As India's energy transition puts long-term pressure on thermal coal demand, CIL has begun diversifying its mineral base rather than remaining a single-commodity miner. Its move into iron ore — becoming the preferred bidder for the large Gadadharpur block in Odisha — marked the company's first-ever entry into iron ore mining, giving it a genuine second mineral revenue stream for the first time in its history rather than simply expanding coal capacity further. It's a strategically cautious first step for a company whose scale, government backing and mine-operating expertise position it to become a more diversified minerals player over time, even as coal remains, by a wide margin, its core business today.
