Indian power generator NTPC plans to purchase two Indonesian coal mines to ensure secure fuel supplies for its plants, which are experiencing a severe coal shortage.

Cost, size, and other details of the purchase have not yet been confirmed.

NTPC says it will need 125 million tonnes of coal per year to meet demand and that it plans to import more than 12 million tonnes in the current fiscal year to meet demand.

Coal accounts for more than 25% of NTPC’s total capacity of 30,644MW.

NTPC, which had earlier purchased stake in Australian mines, also plans to buy coal mines in South Africa and Mozambique.
