Only about 11% of the shore power connections that 31 European ports need by 2030 are guaranteed today, according to Transport & Environment figures based on DNV data. That number sits against a legal deadline that is now less than four years away, and against grid build times of four to ten years.

Two EU regulations meet at the quay in 2030. AFIR obliges TEN-T core and comprehensive ports above a traffic threshold — not just the big hubs — to put shore power on the berth for 90% of qualifying container and passenger calls. FuelEU Maritime obliges those ships, if they stay longer than two hours, to connect and take their electrical load from it. One rule builds the socket. The other forces the ship to plug in.

The date comes from Fit for 55. It is doing the ordering. It is not building the grid.

What does the split look like between ship and shore?

On the ship side, the box can be bought. In July 2026 Cavotec took an order to retrofit containerships with a containerised cable system while the vessels stay in service. DNV reckons about 20% of the world's containerships already carry a shore-power connection. Hapag-Lloyd sits at roughly 35%. A company can fit a ship. FuelEU still names that company even when the quay has no live point, or a chartered ship has no socket.

On the port side, the iron is thinner. Much of the OPS already advertised is low voltage, while deepsea boxes need high voltage. The 90% test is still ahead of the cable.

Can the calendar hold?

The arithmetic is tight. From October 2026 to 31 December 2029 is a little over three years. ESPO, setting out the Commission's grid-connection guidance, puts extra grid build at four to ten years, against two to three years for the port-side connection itself. If the connection request is not already in the queue, parts of the required build may not fit the time left.

Rotterdam is aiming for the second half of 2028. ABB says its kit is meant to supply up to 32 containerships at once. Yet the port's own strategy still records grid congestion. Installed megawatts are not the event the grid sees. The event is coincidence — a 90% coverage test does not ask whether those megawatts are free at 07:00 on a Saturday.

The clock also starts when the ship is alongside, not when the cable is live. Hamburg's routine connection takes about an hour to an hour and a half. If the commercial berth has no socket, the stay can still count as a FuelEU call of more than two hours.

What can a master actually do?

Ask before arrival. Article 6 already lists the misses: no connection point, not enough power or grid stability, incompatibility on a certified ship installation, emergency. From 1 January 2035 those availability exceptions tighten to the lower of 10% of a ship's annual calls or ten calls, unless the company shows it could not reasonably have known — and that showing rests on the information exchanged before entry.

A dead cabinet is a legal category. After 2035, an unasked miss can become a counted one, plus a FuelEU penalty on the electricity that should have come from shore. That is not a hole found later. It is how a duty stays on the books when the connection cannot. IMO 2020 did not need this — a 0.50% fuel could be blended. A substation cannot.

Who pays for the electricity?

The bill is a separate fight. A European Parliament study (759345) finds the EU can mandate the socket and still have no common price rule. Under the Energy Taxation Directive, electricity produced on board at berth must be exempt. Shore-side electricity is not covered by that exemption. A member state needs Council authorisation to apply a reduced rate. Germany obtained one in June 2026, running through 31 December 2029.

In tramp trades, the OPS invoice may not follow the bunker. The visible shore bill is still stacked against the auxiliary engines.

What happens next?

There is no sign of a general 2030 delay. If the megawatts, the berth and the cable are there, the auxiliaries stop. If they are not, the ship stays on its own plant and the call sits on the exception list. AFIR is due a review by 31 December 2026 — the first formal checkpoint where a date that cannot be followed as written gets followed through exceptions, then through reviews. A date can mandate a connection. It cannot manufacture grid capacity. The plug is not the power.
