Coal fired a minefield of controversies in 2012, fuelled by CAG estimates of a huge Rs 1.86 lakh crore loss for allocation of coal blocks to business houses without auction which served as fodder to the Opposition parties to target the government.
The blaze started from a leaked draft report of the Comptroller and Auditor General (CAG) that initially had a figure of Rs 10.6 lakh crore loss resulting from the controversial allocation of coal blocks to about 100 companies without bidding.

The CBI was also roped in to probe into the coal blocks allocated under questionable circumstances.
Several big firms like JSPL, ArcelorMittal, GVK Power, JSW Steel, Bhushan Steel had to face penal action -- either cancellation of allotments to them or forfeiture/deduction of bank guarantee.
Congress MP and industrialist Naveen Jindal-led Jindal Steel and Power was also one of the companies embroiled in the controversy. Some other big names involved in the controversy included former minister Subodhkant Sahai, Premchand Gupta and Vijay Darda.
Another issue which dominated the business news throughout the year was the tussle between Coal India (CIL) and power companies over fuel supply.
Supported by the Power Ministry on the issue, the Prime Minister's Office intervened which led to both Coal and
