Introduction

Port electrification requires a reliable and increasingly flexible electricity system. This includes electricity generation, grid connections, substations, energy storage, shore power systems and digital energy management platforms. As ports electrify vessels, cargo handling equipment and logistics operations, they become increasingly dependent on electricity and electricity infrastructure becomes a strategic asset for decarbonisation, resilience and future growth. This factsheet provides an overview of key electricity system components and infrastructure considerations for ports.

Value proposition

  • Energy resilience

  • System efficiency

Ports are increasingly evolving into integrated energy hubs that combine renewable energy generation, electrified operations, energy storage and smart energy management. Local renewable energy sources, such as wind and solar power, can directly supply port activities, reduce dependency on external energy markets and support port decarbonisation. By coordinating local energy production and consumption, ports can improve energy resilience and system efficiency.

Port applicability

Applicable to most maritime and inland port types and particularly relevant for ports with high (peak) electricity demand, electrification ambitions, renewable energy potential, or grid capacity constraints. Renewable generation can be deployed within the port area or connected through nearby renewable energy assets.

Groups of innovations

  • Renewable electricity generation (wind and solar)

    Ports can generate renewable electricity through onshore wind turbines, solar photovoltaic (PV) systems on rooftops, warehouses, parking areas and unused land, or through connections to nearby renewable energy assets. Local renewable generation can support electrified port operations, reduce dependency on externally supplied electricity, and contribute to decarbonisation objectives.

  • Port grid infrastructure and substations

    As electricity demand increases, due to electrification, ports require robust grid infrastructure, including substations, transformers, switchgear, distribution networks and grid connection upgrades. Reinforcement of electrical infrastructure enables the integration of new loads such as shore power, electric cargo handling equipment, charging stations and industrial electrification projects.

  • Shore power integration

    Shore power systems allow vessels to connect to the onshore electricity grid while at berth, reducing emissions, noise and fuel consumption during port stays, but resulting in more peak demand periods. Integrating shore power within the broader port electricity system can improve utilisation of locally generated renewable energy and support compliance with increasingly stringent environmental regulations. The MAGPIE shore power and peak-shaving demonstrators demonstrated how electricity demand from shore power can be integrated with renewable generation, battery storage and energy management systems.

  • Battery energy storage systems

    Battery Energy Storage Systems (BESS) can store locally generated renewable electricity, reduce peak grid demand and provide flexibility services. Batteries can increase self-consumption of renewable energy, mitigate grid congestion and support operational reliability during periods of high electricity demand. The MAGPIE peak-shaving demonstrator showed how battery systems can reduce peak demand, increase infrastructure utilisation and improve the business case for electrification.

  • Smart energy management systems

    Digital energy management platforms use monitoring, forecasting and optimisation algorithms to coordinate electricity generation, consumption, storage and charging activities. These systems can support demand response, congestion management and more efficient use of existing electricity infrastructure. The Smart Energy Systems Simulator developed within MAGPIE supports the assessment of flexibility needs, congestion risks and infrastructure planning options.

  • Integrated port energy hubs

    The most advanced solution is the development of integrated port energy hubs that combine renewable generation, grid infrastructure (both electricity as other energy carriers, like hydrogen), energy storage, shore power, charging infrastructure and digital energy management into a coordinated energy system. Such energy hubs improve resilience, enhance operational flexibility and enable ports to accommodate future electrification growth while reducing pressure on the wider electricity network.

Port characteristics

Ports require adequate renewable resources, suitable locations for generation assets and sufficient electricity demand to utilize locally generated energy. Energy production infrastructure becomes more attractive when integrated with shore power, storage systems, and smart energy management. Ports facing grid congestion may benefit from increased local energy production, although regulatory and grid connection constraints remain important considerations. The business case depends on utilization levels, electricity prices, and available support mechanisms.
