Average Shore Power Demand Guide
-
The Average Shore Power Demand Guide provides a transparent methodology to estimate auxiliary power demand of ships at berth across major vessel categories. Using GT-based scaling relationships derived from installed auxiliary engine data and calibrated against measured datasets, the guide produces defensible low, average, and high demand envelopes for OPS planning.
Rather than relying on generic bucket averages, the methodology captures operational variability between ship types and sizes, enabling ports, developers, and investors to size electrical infrastructure and evaluate project economics with greater confidence.
OPS capacity planning – Estimate representative berth demand to size grid connections, transformers, and shore connection systems.
Traffic mix analysis – Understand how different ship categories influence total port electricity demand.
Revenue modelling – Quantify energy throughput and income potential for OPS infrastructure.
Benchmarking and validation – Compare results with external references such as DNV, IMO, and EMSA datasets.
Average Shore Power Demand Database
You can use the full Sustainable Ships Average Shore Power Demand Database to further accelerate shore power project development by working directly with structured ship-level data, calibrated load factors, and category-specific scaling functions. The database consolidates auxiliary engine capacity data for 7,000+ vessels, measured operational datapoints, and cross-source benchmarks into a single harmonized environment, enabling transparent estimation of berth power demand, infrastructure sizing, traffic mix analysis, and revenue modelling for OPS projects.
