I've spent the last year talking to fleet operators. Big ones, small ones, last-mile delivery, long-haul, school buses, you name it. FedEx has committed to going fully electric on new delivery vehicles by 2030. USPS just ordered 66,000 EVs. Amazon wants half their deliveries carbon-free by the end of the decade. UPS is retooling entire depots.
These aren't announcements. They're purchase orders. The trucks are coming.
But here's what nobody puts in the press release. Almost every one of these operators is hitting the same wall the moment they try to actually plug the vehicles in.
The depot is the bottleneck
Think about what it takes to charge a fleet of 50 electric delivery trucks overnight. You're looking at 2.5 to 5 megawatts of power draw. That's the equivalent of a small shopping mall, concentrated in a single parking lot. Most fleet depots today are wired for lights, a break room, maybe a forklift charger. Not for megawatts.
The utility’s answer depends on the depot, requested capacity and network work. Some upgrades require substantial lead time; others have a different path. Fleet procurement and charging design need to use the site’s actual utility offer.
And the cost of the upgrade itself? Anywhere from $50,000 to over $500,000 depending on how much work the grid needs. One operator in the UK got quoted 15 million pounds for a single depot. That's not a typo. 15 million for the privilege of plugging in trucks they've already bought.
The trucks show up before the power does
This is the part that keeps coming up. Federal programs like the Clean School Bus initiative are putting thousands of electric buses on order. Districts are signing contracts, getting excited, planning routes. Then the buses arrive and there's nowhere to charge them because the utility hasn't finished the interconnection study yet. Let alone the actual construction.
I watched this play out firsthand. A fleet manager showed me a row of brand new electric vans sitting in a lot. Not broken. Not waiting for drivers. Waiting for power. The chargers were installed. The software was configured. The grid connection was 14 months away.
That's not a technology problem. That's an infrastructure timing problem. And it's happening everywhere.
Smart charging doesn't solve the real issue
People love to talk about smart charging and load management. Spread the charging across the night. Stagger the vehicles. Use software to flatten the peak. And look, that helps. You can reduce peak demand by 60 to 80 percent with good scheduling. A fleet that needs 5 MW on paper might only pull 1.5 MW with smart management.
But 1.5 MW is still way more than most depots have available. You've gone from impossible to slightly less impossible. The fundamental constraint hasn't changed. The wires going into your site can't carry enough current.
The question isn't "how do we charge smarter." It's "how do we get megawatts to a site that was never designed for it."
Diesel gensets aren't the answer either
I keep hearing the suggestion. "Just drop a diesel generator at the depot as a bridge." But think about it for a second. You're electrifying your fleet to reduce emissions and lower operating costs. And your plan is to power the chargers with diesel? The fuel cost alone wipes out the economics. And most of these depots are in residential or commercial areas where a 3,000 kg generator running at 85 decibels isn't going to fly.
Fleet operators need something that actually works at scale across hundreds of sites. Something that deploys rapidly, not years from now. That fits in a parking space, not an industrial yard. That runs on clean fuel. That costs a fraction of a grid upgrade. And that you can monitor and manage remotely when you're running a network of 50, 100, 500 depots.
This market is massive and wide open
There are 87,000 commercial EVs registered in the U.S. right now. That number is growing fast. 53% of heavy-duty carriers are actively transitioning. Another 33% plan to start within the next year. We're looking at a $200 billion market by 2030 just in fleet charging.
But the money isn't in the chargers themselves. The real value is in solving the power delivery problem that sits between the grid and the depot. The big generator companies are focused on data centers and industrial sites. Nobody is building for the depot. The battery storage companies can handle short bursts but not continuous overnight charging for 50 trucks. The utilities are trying, but they're structurally incapable of moving at the speed fleet operators need.
This is why we built Immedia Power
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 designed as a modular distributed power platform targeting 200 kW continuous output, a 15-square-foot footprint, and a 700-kilogram package. The current design supports natural gas, CNG, LPG, biofuel, and hydrogen blends, with grid-parallel operation subject to validation and site approval.
The deployment goal is a shorter path to depot capacity than a major utility upgrade. Utility approval, interconnection, foundation, fuel, permitting, construction, and cost remain site-specific.
The engineering targets include 69 dBA at five meters and Power OS functions for remote monitoring, load coordination, consumption and cost visibility, and predictive diagnostics.
The DOR is being developed as a new on-site capacity option for fleets whose charging timelines are moving faster than utility upgrades.
