Chief Minister Manohar Parrikar stated in the legislative assembly that there were certain "grey areas" in the deal between a private firm and the state-run Goa Industrial Development Corporation.
"I will ask vigilance department to go into parameters of this deal. There are some grey areas. I knew about it. I have raised this issue in 2008. If something substantial is found, then we will act," Parrikar said, replying to a question by independent MLA Rohan Khaunte.
The Goa government has already signed an agreement with the private company which will get the coal from the block alloted to the state in Chhattisgarh, and supply 250 MW of power to Goa.
Parrikar said that Chhattisgarh government was yet to issue mining licence for the block.
It would come within a month and Goa would start getting electricity from the private firm within the next two-three months, he said.
