A SIMULATION-BASED ASSESSMENT OF COST EFFECTIVENESS OF ONSHORE POWER SUPPLY UNDER THE EU ETS FRAMEWORK
Abstract
The study-s aim is to assess the economic and environmental benefits of onshore power supply (OPS) implementation in port areas and to evaluate its cost-effectiveness under different energy price and emission trading scenarios. Specifically, the research investigates how OPS adoption impacts total annual costs, emissions of NOX, SO2, PM, and CO2, and overall cost-effectiveness expressed in euros per pollution unit. A quantitative simulation approach was employed using the OPS Calculation Tool, an Excel-based model designed to estimate annual costs, benefits, and emission reductions for various vessel types. The model includes parameters such as ship call frequency, berthing time, energy consumption, fuel and electricity prices, investment and operational costs, and depreciation rates. Cost-effectiveness was calculated by balancing total OPS-related costs against pollution units. Sensitivity analyses were performed to explore the influence of CO2 pricing and energy mix (diesel vs. grid electricity) on results. The study confirms that OPS is not only an environmentally beneficial measure but also an economically viable solution under the EU ETS regime (EU Emission Trading System). The tool-based simulation helps us to determine if the integration of OPS in port infrastructure contributes effectively to achieving EU decarbonization targets while enhancing local air quality and port sustainability. Future work should extend this model to real-world case studies in European ports to validate simulation results and support policy decision-making for green port transitions.
