METS Technology specialises in high-performance charging systems for city ferries and short-distance routes between nearby towns. These operations run on uncompromising timetables. Ferries cross rivers, fjords and urban waterways dozens of times a day, stopping for only a few minutes at each quay. Every call demands fast, reliable and repeatable power delivery—without exception.
These systems are often compared to shore power installations used by large vessels in ports. At first glance they may seem similar. In practice, they solve very different problems.
When Every Minute Counts
City ferries live by the clock. During a narrow window alongside the quay, they must take on enough energy for the next crossing—often with little margin to spare. Power delivery must be instantaneous. Connections must align automatically. Control systems must communicate with the vessel in real time.
These demands shape every engineering decision. Power electronics are designed to handle extreme peaks. Shore-side battery systems absorb energy from the grid and release it decisively, protecting infrastructure from sudden load swings. Automation is central: automatic mooring, automatic charging interfaces and tightly integrated control systems minimise human intervention. The result is infrastructure that resembles urban rail or metro systems more than a traditional port installation.
City ferries operate to schedule, in all weather, all day—every day.
A Different Logic for Shore Power in Ports
Shore power for large vessels addresses a different operational reality. When a container ship, cruise liner or tanker connects to land-based electricity, time pressure largely disappears. The vessel may remain alongside for hours or days, drawing a stable and continuous flow of power for hotel loads, refrigeration, pumps and onboard systems.
Here, capacity matters more than speed.
Engineering priorities shift accordingly. The challenge is not rapid energy transfer, but ensuring safe, stable and standards-compliant power delivery. Ports reinforce their grids, coordinate closely with utilities and comply with strict international regulations—since a single cruise ship can consume as much electricity as a small town.
Energy Storage vs Grid Strength
Energy storage marks another clear distinction. Ferry charging systems rely heavily on batteries to store and release large amounts of energy instantly. For shore power serving large vessels, energy comes directly from a robust port grid, with little or no buffering.
Operational Resilience
Operational requirements also diverge. If a ferry charger fails, public transport can be delayed within minutes. If shore power is interrupted, a large vessel can usually revert to auxiliary engines—far from ideal, but manageable.
That difference drives system design. Ferry charging solutions are built with redundancy, fallback modes and continuous real-time monitoring from day one. Reliability is not a feature—it is a prerequisite.
In short, while both systems deliver electricity from shore to ship, city ferry charging is about speed, precision and automation. Shore power in ports is about scale, stability and endurance.
