Coal supply. The 1,320MW thermal power project is estimated to use of blended coal (70% domestic coal and 30% imported coal) a year. The domestic coal for the plant is sourced from NTPC's captive coal block Pakri Barwadih in Jharkhand. Pakri Barwadih is the first captive coal mine of NTPC that commenced commercial production in April 2019.

burning gas or coal. In a nuclear plant, the heat is generated by the fi ssion of some of the uranium in the nuclear fuel assemblies. When the nucleus of an atom of, for example, 235U absorbs a neutron, it may split (or fi ssion) into two pieces, giving off energy as heat and a few more neutrons to continue this nuclear chain reaction.
