Abstract

A vital strategy for ports to mitigate the environmental impact of the maritime industry, while complying with frameworks such as the European Green Deal and the Sustainable Development Goals (SDGs), entails the systematic implementation of comprehensive energy management solutions. This paper provides a baseline evaluation of the energy management systems (EMSs) implementation and their impact on energy consumption, carbon emissions, and operational costs in smart ports. Initially, we provide a systematic review of the literature focusing on case studies from prominent ports, including Hamburg, Genoa, Jurong, and Shanghai Yangshan Phase IV. The analysis emphasises key aspects such as energy efficiency, reductions in emissions, and the minimization of operational costs. Subsequently, we formulate an optimisation model to simulate load dispatch, carbon emission reduction, and transport scheduling. Results indicate that EMS deployment reduces annual energy consumption and carbon emissions significantly by approximately 7%-8% and 11%-12% respectively, while achieving substantial cost savings of 30%. The study also identifies critical challenges, including system integration, data quality issues, cybersecurity risks, and the need for standardization. These findings provide valuable insights for port authorities and policymakers, supporting the transition toward more sustainable and efficient port operations.
