I watched a container ship sit at a California port for 28 hours waiting for a berth. The engines were running the whole time. Main engine burning fuel. Auxiliary systems running. It was cold outside, so the bridge heating was on. The crew was working in shifts. Everything consuming power, all drawn from on-board diesel generation.
The ship operator paid roughly $30,000 in fuel for those 28 hours. They also got a compliance notice from California's Air Resources Board. The fine would be $37,500 per day the ship wasn't connected to shore power. In this case, it was about a quarter of a day, so the fine came to a few thousand dollars.
But it added up. By year end, the operator had collected nearly 200 of these notices across their fleet. The fines alone exceeded half a million dollars. The fuel cost was separate. The emissions were separate. These were just penalties for not being plugged in.
And this operator was one of the few actually trying to use shore power when it was available. Most ports don't have it at all.
The regulatory regime tightened overnight
Europe's FuelEU Maritime regulation takes effect in 2030. It requires all TEN-T ports, that's the Trans-European Transport Network core ports, to have shore power infrastructure by a specific date. Not a suggestion. A requirement. Ships that can't plug in face progressively higher penalties. By 2035, the cost of not using shore power gets baked into the fuel carbon intensity calculations in a way that makes it economically punitive.
California got there faster. CARB's rules are in effect now. Ships at regulated berths need to be plugged in. No exceptions for weather, no delays, no "we're working on it." If you're docked and there's shore power available, you better be using it.
And the EU penalty structure is actually worse than California's. The formula is 1.50 euros per kilowatt per hour that a ship remains unplugged. So a 4 megawatt container ship sitting at a berth for 24 hours without power connection costs the operator 144,000 euros. 144K. For one ship. For one day. That adds up fast when you've got a fleet of 50 or 100 ships running global routes.
The infrastructure gap is massive
Here's the problem. Only 3% of global ports have shore power infrastructure. Three percent. And the ports that do have it are mostly in Europe and North America. If you're operating ships globally, you're visiting ports that don't have it.
Installing shore power at a port is not a weekend project. You need high-capacity electrical distribution infrastructure. You need transformers rated for multiple megawatts. You need cable management systems that can handle ships of different sizes. You need safety systems, grounding systems, monitoring systems. The electrical work alone is massive.
Then there's the civil work. You're running cables along the dock. You're installing connection points at each berth. You're dealing with tidal variations, salt spray, constant vibration from ship movement. This isn't building a charging station for cars. It's maritime infrastructure.
The cost for a single berth runs $2 to 5 million depending on the port's existing electrical capacity and the age of the infrastructure. Some older ports quote even higher. A port with 20 berths is looking at $40 to 100 million to fully outfit. And then there's the ongoing maintenance, the electrical monitoring, the connection protocols with ships.
Shipping companies would love to just absorb the cost and move on. But they can't because they don't own the ports. Ports own the ports. And most ports don't have the budget to retrofit their entire docking infrastructure for an incoming regulation they didn't ask for.
Ships need different amounts of power
There's also this problem. Container ships need different amounts of power than bulk carriers. A 20,000 TEU container ship needs 4 megawatts while docked. A tanker needs 1 to 2 megawatts. Some smaller general cargo ships need only 500 kilowatts. And the port cranes that are loading and unloading the ships also need power, often 1 to 2 megawatts per crane.
So a port that handles multiple ship types and wants to operate cranes while ships are plugged in needs to design for variable power demand across multiple berths simultaneously. That's not trivial electrical engineering. And if you get the design wrong or undersize it, you've just spent tens of millions on infrastructure that can't actually deliver what you need.
Port operators are in a bind. They know the regulations are coming. They know the fines are real. But they don't have the capital budget to retrofit everything at once. And the engineering timelines are brutal. Between permitting, grid interconnection queues, and construction, you're looking at years before a new shore power installation is operational. In most markets, six years minimum.
The gap between regulation and reality
This is the exact scenario where you have a regulatory requirement arriving faster than infrastructure can be built. Ships are facing fines starting now. Ports are trying to build the infrastructure to avoid those fines. But the timelines don't align.
A port operator could start building shore power infrastructure today. Best case scenario, it's done in a few years. More realistically, six or more. Meanwhile, ship operators are paying fines, burning fuel, and asking why they're being penalized for a problem the port can't solve.
Shipping lines are also making their own investments. Some are retrofitting ships with battery systems to reduce on-board power generation while docked. Some are installing more efficient auxiliary engines. Some are just absorbing the fines as a cost of doing business in regulated waters. But none of that changes the fundamental constraint: the infrastructure isn't there yet.
There's a bridge solution
What if a port could deploy temporary shore power in weeks instead of waiting years for permanent infrastructure to be built? What if you could cover the gap while you're designing and installing the permanent solution?
That's where compact, grid-parallel generation becomes valuable. You don't need a massive new electrical system. You need clean, reliable power that can plug into what you already have and deliver megawatts to a berth on demand.
The GX230 is a 200 kilowatt multi-fuel generator that's designed for exactly this kind of deployment. It's compact enough to position at a berth. It's grid-parallel, which means it works alongside whatever utility power the port already has. It deploys in days, not months of engineering.
For a port facing near-term regulatory pressure, this is a bridge. You deploy the GX230 at your highest-traffic berths. You provide clean power to ships while they're docked. You reduce the on-board load. You start hitting your compliance targets while you're still building out the permanent solution.
A 4-megawatt ship needs 20 units of 200 kilowatt generators to completely replace on-board power. That's not a single deployment. But for a port cranes that need 1 to 2 megawatts, it's 5 to 10 units. That's deployable. That's doable in weeks. And it buys you time to build the permanent infrastructure.
We're already talking to port operators about this. They understand the timeline crunch. They're looking for solutions that work now, not solutions that are theoretically great in six years. If your port is facing regulatory pressure to provide shore power and you need power delivered in weeks, not years, let's talk.
