The move from the bank comes at a time when the US politicians are urging to stop funding coal-plants.

An Exim official was quoted by the Financial Express as saying that "We are currently reviewing the application, which we received last month, to determine if it satisfies our criteria of ‘reasonable assurance of repayment’ and to ensure that it adheres to our environmental and other policies."

The bank is reviewing a 4,000MW coal mine and power plant located in Jharkand.

Reliance Power, Tata Power and coal mining firm NTPC own the plant, which uses boilers instead of traditional coal-fired power facilities.
