The Electricity System in Bali continues to experience growth every year, where increasing demand for electricity is affected by the increase in the number of electricity consumers in one phase and consumers of electricity in three phases. The Gas Diesel Power Plant (PLTDG) in fulfilling the electricity needs in Bali can supply 200 MW of electricity, sourced from 12 generators. Along with the increase in various types of electricity consumers in Bali, the problem arises in the PLTDG Pesanggaran, namely the occurrence of unbalanced current. A large unbalanced current can cause a trip or a sudden death at the PLTDG Pesanggaran’s generator.Based on the results of the study, the percentage of unbalanced current that occur in the PLTDG in normal conditions ranges between 2% to 3%. But at the time of the trip to the unit 6 generator due to unbalanced current, the percentage of unbalanced current that appeared on the generator just before the trip was 21.69% and has been going on for more than 58 minutes, which exceeds the setting of the relay which only allows a percentage unbalanced current under 8% with a maximum time of 58 minutes. During the trip, the generator only operated 1 unit in block 2, so the magnitude of the unbalanced carried by the generator unit 6 itself.

This study contains an electric power system consisting of generation, distribution and distribution. One type of power plant is a Gas Diesel Power Plant (PLTDG). As industrial activities and population increase, the demand for electrical power also increases. This results in each generator having to be effective and maximum so as not to cause losses, the generator must also be environmentally friendly so as not to cause global warming. Where the effect of specific fuel consumption and load percentage greatly affects thermal efficiency, as well as the amount of fuel consumption greatly affects the economy and CO2 emissions generated at the power plant. Therefore, it is important to know the efficiency from an economic point of view, the performance of the PLTDG power plant and the resulting CO2 emissions. One of the efforts made is by changing the main fuel for the generator. The results of the analysis show that using LNG fuel thermal efficiency, electricity costs per kWh and the resulting emissions are better than using HSD fuel.
