Power plant reliability is an important thing to take into account for future generation planning and evaluating the level of reliability in a power plant, in calculating reliability there are several methods used, in this study using Loss of Load Probability (LOLP), Loss of Load Expectation (LOLE), and Expect Energy Not Supplied (EENS), involving load data for a year, a combination of four generating units, as well as forced disturbance data that occurred during the year. The results of the LOLP calculation obtained a value of 7.97% days, LOLE of 28.9 days and EENS of 2.7815 MW. From this calculation, the reliability value of the generator is still in an unreliable form, so an experiment was carried out to increase power generation by conducting experiments until the value obtained was in accordance with the standard. determination. After carrying out four experiments to increase power generation, the reliability values of these three research methods were LOLP 0.2% day, LOLE 1 day and EENS 0.000899 MW with additional power of 200 MW in each generating unit
