Power for ports
and terminals.
Shore power rules, electric cranes and terminal equipment are adding load at the same time. Plan them together against the capacity the port already has.
The constraint
A vessel at berth needs a compatible connection with enough capacity. At the same time, terminals are electrifying cranes, yard equipment and data systems. These loads compete for the port’s existing connection, and a utility upgrade to a port can take years. How long grid connections take, with sources.
The rules have different scope
FuelEU Maritime began applying in 2025, with shore-power obligations for passenger and container ships at specified ports from 2030 and broader coverage from 2035. California’s At Berth Regulation covers emissions from ocean-going vessels at berth, with compliance through shore power or approved alternatives. Check the current primary sources for each port and vessel type. On-site generation by itself does not establish compliance with a shore-power regulation. Shore power rules and port infrastructure.
Questions to answer before sizing
- Available grid capacity and the utility’s actual connection offer.
- Expected vessel demand by berth and vessel type.
- Crane, yard equipment and data-system loads, and which run at the same time.
- Expansion timing, fuel options, emissions rules and space on the quay.
Options to compare
A site power plan can compare a utility upgrade, storage for crane peaks and local generation. Each option needs the appropriate electrical, environmental and safety review.
Where the DOR fits*
The DOR is being developed as compact on-site power, designed to run alongside the grid and add power as the load rises or, where there is no grid, to carry selected loads on its own. Engineering targets: 0.2 MW electrical output per unit, parallel operation (ten units make one 2 MW package, and packages scale to 100 MW), a 1.4 × 1.0 × 2.0 m unit of about 15 sq ft and 700 kg, about 90 kVA per cubic meter, 69 dBA at 5 m, and a grid-forming inverter for grid-tied, standalone or microgrid operation. Planned fuels are natural gas, CNG, LPG, biofuel and hydrogen blends. An integrated DOR prototype has not yet been built or tested. These are targets subject to integrated-system testing, third-party validation and certification, and first pilot deployments are planned for early 2028 (Q1 2028). See the technology and datasheet.
Common questions
How can ports comply with shore power rules like CARB and FuelEU Maritime without a grid upgrade?
Start with a site power plan covering grid capacity, vessel demand and terminal loads. The pre-pilot DOR is designed to run 0.2 MW units in parallel, ten to a 2 MW package, with natural gas, CNG, LPG, biofuel and hydrogen-blend configurations. Any port or shore-power use requires validation, certification, emissions and permitting review, fuel assessment and electrical integration.
How much power do electric cranes need?
It depends on the crane type, duty cycle and how many operate at once. Size from a measured or engineered load profile of the cranes and other terminal loads that run simultaneously, not from nameplate ratings alone.
Is this an application Immedia Power is pursuing now?
Yes. Immedia is developing the DOR for sites short on power, space or both, and ports are among them. The DOR is pre-pilot. Any use here would require validation, certification, fuel and emissions assessment, permitting and site engineering.
Has the DOR been deployed at a site like this?
No. The DOR is pre-pilot: an integrated prototype has not yet been built or tested, and first pilot deployments are planned for early 2028 (Q1 2028). Figures on this page are engineering targets or illustrations, not results from installed projects.
