I spent time with port operators in Rotterdam, Hamburg, Barcelona, and Singapore this past year. All of them are dealing with the same pressure. Emissions regulations are tightening. Shore power requirements for container ships and cruise vessels are coming. Climate commitments have been made publicly. The message is clear: ports need to electrify their crane operations, and they need to do it now.
The problem is nobody did the power math before making the commitment.
One crane isn't the issue. Twelve cranes are.
An electric ship-to-shore crane needs 1 to 2 megawatts just to run. That's while it's moving containers. A busy container terminal operates 6 to 12 cranes simultaneously. If you do the basic multiplication, a mid-size terminal needs 12 to 24 megawatts available at any given moment during peak operations. That's not theoretical. That's what's required to move the containers that are stacked on the dock.
Now add in shore power for container vessels, which need 1 to 4 megawatts while docked. A large terminal might have 3 to 5 ships at berth at the same time. That's another 5 to 20 megawatts on top of the cranes.
We're talking about 17 to 44 megawatts of continuous power demand just for electrification of one terminal. That's more than the total power consumption of a small city.
The grid is already running out of capacity
Let's talk about EU ports specifically, since that's where the regulations are strictest and the timelines are shortest. European container terminals, passenger terminals, and cruise ports combined require an average of 1,327 megawatts of power. At peak times, demand hits 2,034 megawatts. That's the combined capacity of a major coal power plant, all flowing through the electrical infrastructure of ports that were built in some cases 100 years ago.
Most EU ports are already struggling to deliver enough shore power for container ships. The interconnection infrastructure simply wasn't designed for this load. Upgrading grid capacity to a port takes years of planning, environmental assessment, and construction. And by the time the upgrade is complete, you're supposed to have already added cranes to the same grid.
Port electrification reduces emissions by 60 to 80 percent. That's real. But the grid infrastructure to support it doesn't exist at most ports.
Emissions cuts are real, but they can't wait for grid upgrades
Look, I'm not going to pretend the benefits aren't there. Electric cranes cut operational emissions by 60 to 80 percent compared to diesel equipment. Fewer fumes on the dock. Less noise. Lower lifetime fuel costs. These aren't small wins. For a terminal operator trying to hit net-zero targets, crane electrification is one of the bigger levers they have.
But it only works if you can actually provide the power. And right now, most ports can't, because the grid infrastructure was never built for this scale of demand. A port operator can install electrified cranes, but if the grid connection isn't there, you're stuck running on whatever supplemental power you can cobble together. That usually means backup diesel generators, which kind of defeats the purpose of electrification in the first place.
Distributed power is the bridge
Here's what's actually happening at the forward-thinking ports. They're installing electric cranes. They're building the infrastructure. But they're also deploying supplemental, distributed power generation right on the dock to bridge the gap between what the grid can provide today and what they need to actually run the operation.
A port can compare a utility upgrade with on-site generation and storage for defined crane loads. Each option needs a plan for fuel, equipment placement, controls, emissions and safety. Distributed power still requires applicable permits, electrical integration and utility coordination. It is not an exemption from site engineering.
The best units can also run in parallel with whatever grid power is available, which means they're not just backup. They're supplemental. The terminal uses grid power first, and the distributed unit covers whatever additional demand is needed. It's clean, flexible, and doesn't require betting your emission reduction strategy on an interconnection queue.
Why Immedia Power exists
The grid has traditionally determined where and when businesses can grow. Immedia Power changes that. We combine our unique power-generation system with Power OS, our embedded AI layer, to create the DOR, a new distributed power platform that gives space-constrained sites the on-site power they need to run and scale without waiting on the grid.
The DOR (Distributed On-demand Resource) is a distributed power platform designed for applications including port electrification. It targets 200 kW continuous output, a 15-square-foot footprint, and a 700-kilogram package. The multi-fuel, grid-parallel design requires validation, certification, and integration engineering for each port.
The deployment goal is a shorter path to supplemental on-site capacity than a major utility upgrade. Utility approval, interconnection, dock work, fuel, permitting, and electrical integration remain site-specific.
The engineering targets include 69 dBA at five meters and Power OS monitoring and coordination. Port acoustic performance, controls, and site suitability remain to be validated.
The architecture is designed to parallel multiple units under Power OS coordination. Any terminal configuration requires validated power quality, controls, redundancy, emissions, acoustic, and site-integration engineering.
If your terminal is stuck between an electrification commitment and grid infrastructure that's years away, let's talk about whether a future pilot could fit your operation.
