Power and Coal Minister Piyush Goyal warned that it would take years to alleviate coal supply shortages, which have reduced stocks at thermal power stations to their lowest since a huge blackout in 2012 cut off 620 million people.
Any strategic decisions would have to wait until a final decision by the Supreme Court on whether to revoke licences for more than 200 coal blocks awarded since 1993, Goyal told a news conference.
The court has already ruled that these 'captive' blocks for industrial use were handed out illegally.
It will reconvene on Tuesday to consider whether they should be reallocated, or whether the operators should be fined.
"We will ensure quick action after the Supreme Court decision to get the process rolling and enhance coal output to 1 billion tonnes (a year) by 2019," Goyal told a news conference.
The "Coalgate" scandal, estimated in a 2012 audit report to have cost the taxpayer up to $33 billion, entrenched the dependence of Indian industry on supplies from lumbering state producer Coal India.
Coal stocks on hand at thermal generators, which produce three-fifths of the nation's power, have fallen to six days' forward cover - down nearly half since Modi's national election victory in May.
Modi's landslide came at least in part thanks to his reputation for CEO-style competence as chief minister of Gujarat, where he tackled a similar power crisis in 2005 and ensured round-the-clock electricity supplies.
