In the distribution of electrical energy from the plant to the consumer, there is a decrease in quality due to the loss of power (losses). These power losses are caused by a voltage drop across the line and subsequently producing a power loss on the line. This power loss can be classified into two types based on its line parameters, i.e., active power loss and reactive power loss. The line’s active power loss generates losses of power/losses so that the active power reaches the load on the receiving end is always less than the productive power of the sender side. Power losses in the electrical system must exist and cannot be reduced to 0% (zero percent). According to SPLN No. 72 of 1987, the permitted distribution network’s power loss should not be higher than 10%. This paper investigates the magnitude of the voltage loss and the line active power losses on the 20 kV distribution line. The calculation conducted through case study and simulation of Etap 12.6 program on an electrical power distribution system that is 20 kV distribution line in PT. PLN (Persero) Rayon Muara Labuh. In the distribution line 20 kV, there is IPP (Independent Power Plant) PLTMH PT SKE used to improve the stress conditions in Rayon Muara Labuh. Therefore the loss of power will be calculated in 3 terms, i.e., before and after IPP PT. SKE with 20 kV distribution lines as well as on feeder load maintenance (as a repair action plan). The simulation results show the highest voltage drop and the highest power losses continue generated during IPP. PT SKE has not done synchronized with the distribution line of 20 kV with a significant voltage drop of 1,533 kV percentage of 7.93% and power loss of 777.528 kWh percentage of 7.69%.
