The primary energy source in developing countries, including Indonesia, is fossil energy. Therefore, evaluating the environmental impact of coal-fired steam power plants is crucial, but limited. Comprehensive scientific analysis is required to develop appropriate alternative measures. This research aims to analyze the life cycle impact of the coal power plant at the gate, including the coal yard, coal crusher, boiler, turbine, and generator, with the functional unit of 1 kWh of electricity produced. This research provides clear recommendations for mitigating emissions from the main contributing units. The analysis reveals the highest impact in the climate change potential category (1.40 × 10^-1 kg CO₂ eq/kWh), while the smallest impact was recorded in the Eutrophication potential category (7.55 × 10^-4 kg PO₄ eq/kWh), with no impact on ozone depletion in the stratosphere. The operation of boiler and generator units (gate hotspots) are the main contributors to climate change impacts, including carbon dioxide (9.25 × 10^-2 kg CO₂ ), sulfur dioxide (8.21 × 10^-3 kg SO₂ ), and nitrogen dioxide (7.55 × 10-4 kg PO4 ). Alternative programs that may be implemented to reduce emissions include co-firing and installation of flue gas desulfurization and low NO_x burner. The findings of this research provide guidance for developing a policy framework to promote more environmentally friendly coal power plants, thereby achieving greater energy sustainability.
