Global awareness of climate change has prompted various industries to evaluate the environmental impacts of their operational activities, particularly concerning the greenhouse gas emissions produced. PT PLN Nusantara Power UP Indramayu, as part of the energy sector, also generates significant greenhouse gas emissions with substantial environmental impacts. This paper analyzes the greenhouse gas emissions at PT PLN Nusantara Power UP Indramayu using the Life Cycle Assessment (LCA) method with a functional unit of 1 kWh and a gate-to-gate scope, covering electricity generation activities from the condenser unit to the generatortransformer unit. The hotspot of the electricity generation activity was found in the boiler unit, contributing 99.98% of the global warming potential (GWP) impact from the overall GWP value of 0.001020865 tonss CO2 eq/kWh. Similarly, the boiler contributed 99.99% to the overall photochemical ozone creation potential (POCP) impact from the overall POCP value of 0.000703089752 gr C?H? eq/kWh. A trend of increasing greenhouse gas emissions from the Indramayu coal-fired power plant was also observed, with an emission increase of 4.89% from 2021 to 2022 and 5.31% from 2022 to 2023. Recommended solutions for reducing greenhouse gas emissions include optimizing co-firing technology, implementing carbon capture technology, and utilizing Ultra Super Critical (USC) Boilers.
