What is the capacity of the largest thermal power generation unit currently running in India ________________?
Show answer Hide answer
Answer: E. 500 MW
Explanation
Thermal power generation units in various large-scale stations reach individual capacities up to 500 MW. Electrical grids in major developing nations incorporate large subcritical and supercritical thermal units rated at 500 megawatts. Standardizing on 500 MW turbine-generator sets allowed utilities to achieve significant economies of scale in thermal power generation. Thermal power plants convert chemical energy from fossil fuels into electrical energy using high-pressure steam Rankine cycles. Large generating units require massive boilers, steam condensers, cooling water towers, and high-capacity electrical generators. Grid stability requires balancing power output from large centralized units with fluctuating consumer demand profiles.
Units rated at 30 MW are obsolete for modern centralized baseload power generation and are limited to captive industrial plants. A 60 MW capacity represents older, smaller-scale utility generation units that have largely been superseded by larger machinery. A 100 MW unit is smaller than the major large-scale thermal power generation blocks deployed in primary regional grids.
