EU regulations require OPS from 2030. Rotterdam has developed its own shore power strategy.
A combination of infrastructure, financing, operations, and customer integration.
Port strategy affects switchgear, protection logic, and load management on board.
Whether ports roll out shore power in a scalable and standardised way.
A robust shore power strategy encompasses five dimensions that are frequently insufficiently integrated in practice: grid capacity, infrastructure planning, operating model, customer integration, and financing.
Grid capacity is the fundamental prerequisite. A large container terminal with six berths can generate a simultaneous power demand of 60 to 80 MW. This load must be available in the regional power grid, which in many port cities requires substantial grid expansion measures. Lead times for grid expansion are three to five years, meaning grid planning must precede infrastructure planning.
Infrastructure planning concerns the physical equipment of berths: transformers, frequency converters, cable reels, plug devices, and control systems. Standardisation per IEC/IEEE 80005 helps, but concrete installations must be adapted to the respective vessel types and berth configurations. A cruise terminal poses different requirements than a container terminal.
The operating model defines who operates the shore power: the port operator itself, an energy supplier, a specialised service provider, or a joint venture. Each model has different implications for investment risk, operating costs, and pricing. Rotterdam has opted for a model where the port provides the infrastructure and specialised operators manage the service at terminals.
Customer integration means that the strategy systematically incorporates the needs of vessel operators. This encompasses pre-clearance of connection compatibility, booking systems for shore power slots, transparent pricing structures, and technical support during the connection process. Without a functioning customer interface, even the best infrastructure remains underutilised.
Financing is the fifth dimension. Shore power infrastructure requires high upfront investments with initially low utilisation. Funding programmes (CEF, national programmes) can improve the business case but typically cover only 30 to 50 per cent of investment costs. Refinancing through usage fees must be realistically calculated.
Shore power is becoming a competitive factor between ports. Ports with functioning shore power supply can enable lower emissions costs for vessels (EU ETS, FuelEU Maritime), influencing the total cost of a port call. Shipowners will increasingly align their route planning with the availability and cost of shore power.
For port authorities, this means shore power is not an isolated sustainability project but an instrument of location policy. A port without reliable shore power supply risks losing traffic to competing ports that offer this service.
For shipowners, a reciprocal dynamic emerges: the investment in onboard shore power capability only pays off if sufficiently many ports of call offer shore power. Conversely, ports only invest if enough vessels are shore-power-capable. This chicken-and-egg problem is being resolved by EU regulation, which obliges both sides simultaneously.
Rotterdam’s shore power strategy is currently the most ambitious in Europe. The port plans to equip all major terminals with shore power by 2028 and has established a dedicated shore power subsidiary for this purpose. The strategy integrates grid expansion, infrastructure planning, and customer service under one roof.
A key element is pricing. Rotterdam offers shore power at competitive prices, enabled by exemption from electricity tax and EU funding. Price transparency is deliberately high to give shipowners a reliable basis for calculation.
Hamburg pursues a similar approach but contends with higher grid expansion costs and more complex permitting procedures. Experience shows that political support at the municipal and national level is a decisive success factor. Rotterdam benefits from the strong position of the port in Dutch economic policy.
Shipowners and fleet managers should evaluate port strategies against five criteria. First: commitment – does the port have binding timelines or merely declarations of intent? Second: financing – is funding secured or dependent on uncertain grant commitments? Third: grid capacity – is the power supply secured for the planned expansion? Fourth: customer integration – are there booking systems, price transparency, and technical support? Fifth: experience – does the port already have operational experience with shore power, or is everything still on paper?
Ports that score strongly across all five criteria deserve prioritised consideration in fleet planning.
