Techno Economic Modeling for Replacement of Diesel Power Plant

Several problems occur in an old diesel power plant such as derating, low efficiency, high emission and noise decrease the performances of the systems. Besides, most of the old diesel power plants in Indonesia is still use High-Speed Diesel (HSD). In order to decide if the old diesel power plant is still feasible from the technical and economical point of view, a detailed analysis should be done. This paper proposes a model management tools to determine its techno-economic feasibility analysis from some factor such as cost, reliability, availability and economic life. This paper also propose the modeling calculation of Cost of Electricity (COE), Life Cycle Cost (LCC) and Equivalent Uniform Annual Cost (EUAC) methods to determine in techno-economic. A simple case study is discussed. The result recommends for asset retirement without abandonment for the old diesel power plant and replacement with the new Power Plant using a dual fuel engine (Gas Fuel and Marine Fuel Oil (MFO)). From the new power plant, it also can be estimated the replacement should be carried out in 14th year for the future. Finally, model management tools can be used to facilitate decision making in similar cases in the diesel power plant.
