"It has been decided that Sasan Power is required to revise the mining plan of Moher and Moher Amlohri Extension coal blocks from the present 20 MTPA mine capacity to 16 MTPA so as to conform to the coal requirement of Sasan UMPP, it being a specified end-use plant," the Coal Ministry said in a letter.
The company declined to comment on the letter.
The government last month had taken away one of the the three coal blocks allocated to Reliance Power's Sasan project in Madhya Pradesh. The Supreme Court had scrapped allocations of 204 coal blocks last year.
In March, Reliance Power said its 3,960-MW Sasan thermal power project had been fully commissioned.
Anil Ambani-led Reliance Power has already announced termination of the contract for Rs 36,000-crore Tilaiya UMPP in Jharkhand over "inordinate delays" in land acquisition.
