While a company spokesperson declined to comment on the matter, sources said the project, fired by imported coal and an important source of electricity for the state, has been facing financial difficulties due to outstanding payments for power supplied to Karnataka.
When contacted, Karnataka Energy Minister D K Shivakumar told PTI that all bills have been paid to the firm and that the state had even given Rs 300 crore in advance.
"We will manage the (power) situation and have the alternative... And (this time) we are having good rain," he said.
Meanwhile, sources said with dues yet to be paid, it has become difficult for the plant operator to purchase overseas coal.
