Genset is one of the important equipment that must be available in public places as a backup power source, in the event of a power outage from the main power source. This research analyzes the capacity evaluation of generators in the regional secretariat building of the Pln Ulp Lambaro Building in May 2025. This building has a total load of 677 kW supplied by PLN medium voltage 20 kV and lowered by a step down transformer of 630 kVA. Current observations were made at Non-Peak Load Time at 12:30-14:30 and Peak Load Time at 17:15- 19:15. From the results of this experiment it can be concluded that in May 2025 the highest peak load usage was 568.67 kW or 710.83 kVA. After the calculation, the generator power capacity in the building is 651.61 kW, while the generators used are two units with a power capacity of 1280 kW. Thus, the generator set has met the building's electrical energy needs. The generator efficiency when the generator works for 60 minutes in the building is still relatively low, which is 26.25%. The ACB safety rating value used in the generator set that exits to the Low Voltage Main Distribution Panel (LVMDP) has a rating of 2000 A for one generator unit and 4000 A for two synchronous generator units, which is in accordance with the calculation of the safety capability value of the PUIL 2000, 2011 and 2020 references
