Energetic and exergetic analyses of a 626 MWe supercritical power plant-based mazout oil-fired are carried out to assess the system's performance. The energy losses and exergy destruction are evaluated for each system component using real actual data. The results show that the boiler is the primary source of irreversibility with 88.62% of the total exergy destruction. The intermediate pressure turbine maintains an exergy efficiency of 97% at 100%-load. Moreover, the maximum thermal efficiency is achieved at 100%-full load by 44.85% whereas, the maximum overall exergy efficiency of 40% is acquired at the maximum continuous rate condition of 105%-load.

Solar energy is the most readily available energy in India, which can be utilised in coal-fired thermal power plants for feedwater heating and Monoethanolamine (MEA) for MEA regeneration in post-combustion CO2 capture unit. The present study deals with 4-E (energy, exergy, environment, and economic) analysis of a 500 MWe Supercritical (SupC) coal-based thermal power plant with solar-assisted feedwater heating and MEA regeneration in CO2 capture unit. Results show that the plant efficiency is improved by 8.2% points, and the coal consumption rate is reduced by 18%. The levelised cost of electricity (LCoE) generation is increased to INR 6, and the cost for CO2 avoided is INR 3607 per tonne of CO2.
