🔢 Key Formulas

Pout=η×PinP_{out} = \eta \times P_{in}Pout​=η×Pin​ — representing the generation efficiency of a thermal unit

⚙️ Working Principle

NTPC operates on the principle of large-scale bulk power generation. It converts chemical energy (coal/gas) or potential energy (water) into electrical energy, which is then transmitted via the Power Grid Corporation of India (PGCIL) to various State Discoms and bulk consumers under the ministry of power guidelines.
