Evaluating renewable energy strategies for operational efficiency in seaports

This study provides a comprehensive assessment of solar energy integration and fuel efficiency optimization in the Bushehr Commercial Port, addressing a critical research gap in sustainable maritime logistics. While global trade has intensified port energy demand, existing studies lack a comprehensive assessment of operational energy efficiency in commercial ports. This paper introduces an innovative framework that quantifies the technical benefits of solar photovoltaic (PV) systems in port operations. Using pv syst software, including solar radiation analysis and port-specific energy assessments, the study shows that the deployment of 6,336 PV panels, each with a power of 585 W, results in a total installed capacity of 3,707 kWh. The system exhibits an annual energy generation rate of 7,385,951 kWh with a performance ratio (PR) of 83.92%, indicating high operational efficiency. Furthermore, the analysis of fossil fuel consumption shows significant seasonal fluctuations, with peak diesel consumption exceeding 10,578,132 liters in February due to increased operational demand, while the summer months show lower consumption. The findings highlight the critical role of solar photovoltaics in reducing seaports’ dependence on conventional fuels, thereby reducing greenhouse gas emissions and operating costs. This paper contributes to the strategic transition towards low-carbon port infrastructure and provides a replicable model for implementing sustainable energy in maritime hubs with high solar potential. Future research should focus on long-term energy resilience and optimization strategies for long-term outage scenarios.
