The aim of this study is to assess and evaluate the performance of a large-scale thermal power plant (TPP). The performance rating was conducted in compliance with the statistical principles. The data for this analysis were obtained for a TPP with an installed capacity of 375 MW during a span of 8 years (2010–2017). Four parameters were used to evaluate the performance of the TPP including the availability, the reliability, the capacity factor, and the thermal efficiency. These parameters were calculated using a set of equations and then compared to the international best practices and target values. The results indicate that approximately 91% of the expected capacity was available throughout the studied period against the industry best practice of 95%. However, the average TPP’s reliability was found to be approximately 95% against the target value of 99.9%. Furthermore, the average capacity factor throughout the studied period is 70% as against the international value of 40–80%. Moreover, the thermal efficiency of the TPP is 40% against the target value of 49%. Due to the outage hours and malfunctions, the power losses throughout the studied period reached 846 MW. Overall, the analysis indicates that the studied TPP is not within the scope of the best industrial practices.

这项研究的目的是评估和评估大型火力发电厂（TPP）的性能。绩效评估是根据统计原则进行的。此分析的数据是针对在8年（2010-2017年）内装机容量为375 MW的TPP获得的。使用四个参数来评估TPP的性能，包括可用性，可靠性，容量因子和热效率。使用一组方程式计算这些参数，然后将其与国际最佳实践和目标值进行比较。结果表明，在整个研究期间，约有91％的预期产能可用，而行业最佳实践为95％。然而，发现TPP的平均可靠性约为95％，而目标值为99.9％。此外，整个研究期间的平均产能因子为70％，而国际价值为40-80％。此外，TPP的热效率为40％，而目标值为49％。由于停电时间和故障，整个研究期间的功率损耗达到846兆瓦。总体而言，分析表明，所研究的TPP不在最佳工业实践的范围内。
