Uncontrolled Keywords:	Abstract: The number of high power users operating in the subsystem will rise in line with economic expansion, which will result in overloading conditions on the inter bus transformers (IBT). To overcome the overload condition of 500 kV/150 kV (IBT) in the X area due to load forecasting, 2×400 MW power plant is planned to be moved from 500 kV bus into 150 kV bus. This research aims to analyze the power flow and short circuit study before and after the migration is implemented. The method used in this research is a simulation using ETAP software. From the results of the power flow study, it can be concluded that the migration of 2 units of power plant can reduce the load on IBT 1 and IBT 2 both under normal conditions and during contingency in one of IBTs. In addition, it also increases the bus voltage profile, reducing losses in the 150 kV sub-system area. From the results of the short circuit study, migrating 2×400 MW power plant units, is safe in terms of equipment durability.

Introduction Currently, steam power plant is still one of the dominant types of power plants in Indonesia. This cannot be separated from the fact that Indonesia is the largest coal producer in the world. The continuous use of coal will certainly cause serious environmental degradation and higher business costs [1], [2]. The International Energy Agency (IEA) reveals fossil fuel Coal accounts for 44% of global CO2 emissions. Coal combustion is the largest source of GHG (green house gas) emissions, which trigger climate change. In addition, from various studies, the environmental studies that mention coal mining and combustion have a poor impact on life and recommend that mining and combustion activities should continue. Coal is problematic because its extraction, processing, and use damage the environment [3]. Therefore, it is necessary to take strategic steps by changing the energy paradigm, gradually reducing the use of fossil energy, reducing subsidies on energy prices, providing national energy reserves, taking responsibility for regional energy needs, and prioritizing energy development [4], [5], [6].
