The Port of Rotterdam is the largest port in Europe. It handled 13.82 million TEU in 2024 and grew to 14.2 million TEU in 2025, ahead of Antwerp-Bruges on 13.53 million and Hamburg on 7.8 million. These ports form the Hamburg–Le Havre range — the North Sea cluster that also takes in Bremerhaven, Amsterdam and Le Havre — and between them they move more containers than the rest of the continent's ports combined, alongside crude, refined products, LNG, RoRo and cruise.
That concentration is exactly why the European Union chose this range to carry its shore-power obligations first. Two regulations adopted in 2023 turn onshore power supply from a voluntary measure into a dated requirement — one aimed at the ship, one at the port — and both bite in the ports a great deal of the world fleet already calls. For an owner, the practical consequence is a fixed 2030 horizon and a queue of vessels needing the same engineering before it.
The Hamburg–Le Havre range: Europe's busiest port cluster
The Northern European range is where the largest share of EU maritime traffic concentrates, which is why the regulation targets it. Rotterdam and Antwerp-Bruges alone handle more boxes each year than the next several EU ports together, and the range mixes deep-sea container, tanker, RoRo and cruise calls in a small geographic area. The vessels that trade here are, disproportionately, the container and passenger ships the shore-power rules name first.
- Rotterdam: Europe's largest port, 14.2 million TEU in 2025, plus major crude, product and LNG throughput
- Antwerp-Bruges: 13.53 million TEU in 2024, second in the EU and closing on Rotterdam
- Hamburg: 7.8 million TEU, the third-largest container port in the range
- Amsterdam: a major energy and bulk port and a growing cruise gateway on the IJ
- Le Havre and Bremerhaven: the western and eastern anchors of the range
Do container ships have to use shore power in the EU?
Yes. Under FuelEU Maritime (Regulation (EU) 2023/1805), from 1 January 2030 container ships and passenger ships of 5,000 gross tonnage and above must connect to onshore power supply and use it for their electrical demand while moored at a quayside in a TEN-T core port, whenever the stay exceeds two hours. From 1 January 2035 the obligation extends to all EU ports where shore power is installed. The exceptions are narrow: calls under the two-hour threshold, unscheduled or emergency calls, situations where the port cannot supply compatible power, and vessels using an accepted zero-emission technology instead. A plan built on the exceptions is fragile, because most scheduled container and cruise calls in Rotterdam or Amsterdam sit well over two hours.
What AFIR requires of the ports themselves
The matching obligation sits on the port. The Alternative Fuels Infrastructure Regulation (Regulation (EU) 2023/1804) requires TEN-T core maritime ports to provide shore-side electricity by 2030, in sufficient quantity to meet at least 90 per cent of the demand from container and passenger ship calls, measured against the average annual number of such calls over the preceding three years. The two laws were written to land together: the ship rule only works if the socket exists. In practice the build-out is uneven, so which of your regular berths will actually be equipped — and at what voltage and frequency — is a question worth putting to the terminals now, not in 2029.
Shore power at the Port of Rotterdam
Rotterdam is among the most advanced ports in Europe on shore power, and it started early. The city and the Port Authority launched their first shore-power strategy for seagoing vessels in 2020, ahead of EU law, and have since set out an updated Shore Power Strategy for 2025 to 2035. The port already operates more than 100 shore-power installations with a combined capacity above 43 MW, and the cruise terminal at Wilhelminakade was commissioned in 2025. The aim is for shore power to be standard for a large part of shipping by 2030, and zero-emission berthing by 2050.
The container roll-out is larger again. Rotterdam Shore Power has contracted ABB to engineer and build what is expected to be the world's largest shore-power system by total capacity, over 100 MVA, delivering power at 35 connection points across APM Terminals Maasvlakte II and the Hutchison Ports ECT Delta and Euromax terminals — enough to serve up to 32 container ships at once. Studies are running at four large sites: ECT in the Amazonehaven, APMT2 in the Amaliahaven, the Vopak terminal in the Botlek, and the cruise terminal. For a boxship owner, that means the quay side is arriving at the terminals you call — the constraint moves to the ship.
Shore power at the Port of Amsterdam
Amsterdam brought sea-cruise shore power online in June 2025. The installation at Passenger Terminal Amsterdam supplies up to 16 MW and can serve one sea-cruise vessel plus up to eight river-cruise vessels; the grid operator laid 4.4 kilometres of cable under the IJ and built a Smart Energy Hub on the quay to house the transformers and shore-power equipment. From 2027, shore power will be mandatory for sea-cruise vessels calling Amsterdam — ahead of the EU-wide date. The port also runs one of Europe's larger inland-shipping networks, with 71 OPS installations and 205 plugs for moored inland-navigation and river-cruise vessels.
What does "ready to plug in" mean technically?
Being ready means the vessel carries a completed high-voltage shore connection, not a promise to fit one. On a commercial ship that is a shore-connection inlet and cable-management arrangement, a shore-connection switchboard, a step-down transformer, and protection and interlocking engineered to IEC/IEEE/ISO 80005-1 — the high-voltage shore-connection standard, typically at 6.6 kV or 11 kV. Much of the EU quay supply is 50 Hz; where a vessel runs at 60 Hz and the terminal has not installed conversion, a frequency converter has to sit on board, which changes the weight, cooling and space demands of the whole scope. Where that converter lives is a decision to settle early, because it reshapes the on-board work.
The approval and long-lead timeline against 2030
The step owners most often underestimate is not the hardware but the clock behind it. A shore connection alters the vessel's single-line diagram, so it is a class-approved modification: drawings go to class ahead of the work, and the approval turnaround is a real item on the schedule. Transformers, converters and HV cable carry lead times that compete with every other owner working to the same 2030 date, and the dock window has to be booked against those dates rather than the survey date. Starting the engineering in good time is what separates a ship that is compliant on its first 2030 call from one still waiting on a converter when the rule bites.
Frequently asked questions
- Which EU ports are covered by the FuelEU Maritime shore-power rule from 2030?
- From 1 January 2030 the at-berth obligation applies in TEN-T core maritime ports — the EU's main network ports, including Rotterdam, Amsterdam, Antwerp-Bruges, Hamburg and Le Havre. It covers container and passenger ships of 5,000 GT and above. From 1 January 2035 it extends to all EU ports where shore power is installed, not only the core network.
- Does a ship have to plug in for a short call in Rotterdam?
- Not if the stay is under two hours. FuelEU Maritime applies the at-berth connection requirement when a covered vessel is moored for more than two hours at a quayside in a TEN-T core port. Unscheduled and emergency calls, and calls where the port cannot supply compatible power, are also treated differently — but most scheduled container and cruise calls in Rotterdam run well beyond the threshold.
- Is EU shore power 50 Hz, and does a 60 Hz ship need a converter?
- Much of the European quay supply is 50 Hz, while a large share of the world fleet runs at 60 Hz. Where the terminal has not installed frequency conversion, a 60 Hz vessel needs a converter on board to take the connection. Converters are heavy and need cooling and space, so deciding whether conversion sits ship-side or shore-side is a design decision to resolve before specifying the retrofit.
- When does shore power become mandatory for cruise ships in Amsterdam?
- From 2027 the Port of Amsterdam will require sea-cruise vessels to use shore power, ahead of the EU-wide FuelEU date of 2030. The Passenger Terminal Amsterdam installation, commissioned in June 2025, supplies up to 16 MW and can serve one sea-cruise ship alongside up to eight river-cruise vessels. Cruise operators calling Amsterdam should treat 2027, not 2030, as their planning date.
