'It will take about a week to resume production as we are in talks with companies like South Eastern Coalfields to improve supply,' Paranjape told IANS over phone.

He, however, declined to explain the reason behind the coal shortage. The project needs three million tonnes of the feedstock annually.

Of the 500 MW generated, 280 MW is to go to state-owned SAIL's Bhilai Steel Plant, 100 MW to the union territory of Dadra and Nagar Haveli, 70 MW to the union territory Daman and Diu, and the remaining 50 MW to Chhattisgarh.
