When Port Electrification Meets Real Operations: Microgrids, digital twins, and automatic identification system-driven energy awareness.

Abstract

Ports are entering a new phase of electrification. Shore power, solar generation, battery storage, charging systems, and electrified equipment are being deployed more widely, but their value depends not only on installation but on how well they respond to vessel activity and berth operations as they happen. The challenge is that port demand is not static. It shifts with arrivals, departures, cargo handling, tug support, shore power connection, and charging events for vessels and port equipment, creating short but important electrical stress that static planning assumptions often fail to capture. This article discusses a practical way to address that problem by combining the port microgrid as the electrical backbone, the digital twin as a synchronized virtual representation and decision layer, and automatic identification system (AIS)-based vessel awareness as the operational context that reveals when demand is likely to change. Together, these elements can help ports move from reactive operation toward better-timed use of storage, renewable energy, shore power, charging infrastructure, and grid support. The broader message is simple: the smart port of the future is not only electrified but operationally aware, data informed, and closely aligned with real maritime activity.
