Transmission shrinkage / losses have several factors, including the factor that the distance between the plant and the load center is too far. This study uses power flow analysis and calculation of transmission loss coefficient (loss coefficient). Using the calculation of the power flow of the Newton-Rapson method in the Equatorial System, it can determine the magnitude of active power losses and reactive power losses. The calculation of power flow in the Equatorial System is carried out in several scenarios, namely scenario 1 condition without operation of the UPP GCL PLTU, scenario 2 of the july-December 2022 operating pattern assuming the entry of GI Sekadau and GI Sintang, and scenario 3 uprating and network configuration. Based on the total active power losses of the Equatorial System channel from the three scenarios used, it still gets transmission shrinkage within normal limits, namely the threshold of transmission line losses of around 5-15% (Jaleani, 2013).} }
