Electricity is a primary necessity that must be supplied continuously with reliable quality to meet increasing societal demand. However, technical losses in distribution systems, particularly those caused by transformer load imbalance, can reduce system efficiency and lead to energy losses. This study aims to analyze the effectiveness of load-balancing methods in optimizing kWh energy savings at the JE016 substation in Labu Lalar, operated by PT PLN (Persero) ULP Taliwang. This research employs a quantitative experimental approach using load measurement data obtained from field observations and the AMG application. The analysis focuses on load-imbalance percentage, neutral current, power losses, and energy losses before and after load-balancing implementation. The results show that the load-balancing method successfully reduced the load-imbalance percentage to 20.29% and decreased the neutral current to 40.67%. Consequently, energy losses were reduced to 241.52 kWh, while the transformer achieved energy savings of up to 25.53 kWh. These findings indicate that load balancing significantly improves transformer efficiency by minimizing losses and optimizing energy usage. In conclusion, the implementation of load balancing is an effective strategy for reducing technical losses and enhancing energy efficiency in distribution substations. This method can be applied as a practical solution to optimize transformer performance and improve the quality of electrical power distribution.
