<p align="justify">Coal-fired power plants are the main source of global electricity as coals are the cheapest fossil fuel to date. With the high capacity this plant provides, governments and even venture capitalists will eventually see an attractiveness of investing to a coal-fired power generation. But, as environmental regulations tighten, there is a need to improve the design, operation and control of existing or new built coal-fired power plants. Modelling and simulation is identified as an economic, safe and reliable approach to reach this objective. The modelling and simulation of Suralaya Power Station’s 5th Unit using the software Ebsilon Professional has been executed with success. The operation point of said plant is set in variation so we can see the effect of said variation to the plant’s performance which tells us that the superheat and reheat steam temperature have a great influence on increasing the plant efficiency. Three proposed models for efficiency improvement of this plant have also been modelled successfully. The first model sees an improvement of 0.3%, this model swapped the boiler feed pump turbine to a three phase motor. The second model has no improvement in efficiency but has a decrease of fuel consumption around 20 tons/hour, this model adds aftercooler components to model drain coolers in feed water heaters. The third model combines both of the earlier models, where a three phase motor is used instead of a boiler feed pump turbine, and drain coolers for the feed water heaters are used. This model sees an efficiency improvement of 0.5% and a decrease on fuel consumption for around 20 tons/hour. The effect of using other brands of coal to the plant fuel consumption is also observed.<p align="justify"> <br />
