In the process of distributing electrical energy to consumers or customers, there is a difference in the value of the electrical energy distributed to the electrical energy sold. The difference in the amount of electrical energy is due to energy losses or losses. Energy losses or losses are the loss of electrical energy that occurs during the process of distributing electrical energy, this value can be seen from the difference in the value of the electrical energy sent to the value of the electrical energy received. The location of Detian Feeder is located in an urban area, so efforts are made to keep the value of energy losses relatively small so as not to result in a relatively large loss for PT PLN. In this study using quantitative methods and calculation methods used to calculate the value of energy losses is to use the difference in energy difference (kWh). Based on the calculation of the difference in energy difference (kWh) that has been carried out, the value of the energy losses that occurred during the 2022 period from January to August 2022 is 9,719,376 kWh, with an average of 1,214,922 kWh and a proportion value of 7.64%. . The results of the calculation of the energy loss value exceed the standard limit that has been set based on SPLN 72:1987, which is 5%. Then the method used to reduce the losses is in the form of a method of solving the load on the feeder to a new feeder, balancing the load on the transformer, repairing the connection points, managing overloaded transformers, selling as much energy as possible and implementing P2TL} }
