Electric trucks are no longer the constraint. Grid capacity is. A mid-size distribution centre adding truck charging on top of normal warehouse operations typically needs contracted power well beyond what legacy industrial sites were built for, and in congested parts of Europe, getting more of it from the local grid operator can take years rather than months. Where that connection falls short, battery energy storage (BESS) paired with an energy management system (EMS) has become the standard way tenants and landlords bridge the gap while a grid upgrade works its way through the queue.

This guide sets out how much power different types of e‑truck charging actually require, how to weigh BESS against a straightforward grid upgrade, and what to check before committing to a lease or a site.

Charging hardware is a mature, off-the-shelf category at this point. The harder problem sits upstream. Most industrial estates and distribution parks were designed decades ago around office and warehouse loads, not around vehicles that draw many times the power of a typical car charger. Requesting more capacity from the local grid operator can take a long time in congested regions, and on some connections, feeding surplus power back isn’t possible at all.

For a tenant planning to electrify a fleet, that turns grid capacity into a site selection criterion in its own right. It belongs in the same conversation as clear height and dock door count, not something to sort out after the lease is signed.

Buying a truck charger is the easy part. Charging hardware is widely available and proven. Getting enough electricity to that charger is where projects stall.

Most European industrial estates were designed decades ago, long before anyone planned to charge trucks there. In busy regions the local grid is already full. A request for a bigger connection can take years, and some sites cannot send surplus solar power back to the grid at all.

That turns power supply into a site selection criterion. It belongs on the same checklist as clear height and the number of dock doors, not on a to-do list after the lease is signed.

It depends on three things: how fast trucks need to charge, how long they stand still, and how many charge at the same time.

A WDP site in Raamsdonksveer, the Netherlands, shows both the problem and a way through it.

• What the site needed: around 200 kW at peak times.
• What the grid could deliver: 69 kW, roughly what six home EV chargers draw, with no option to send surplus power back.
• The solution: solar panels, a battery to store their energy, and an energy management system to steer both.
• The result: 269 kW of available power, expandable step by step, and a building that keeps running during grid congestion or a power cut.

The site did not wait years for the grid operator. It closed the gap on its own terms.

The two can go together, but they solve different problems.

A grid upgrade makes the pipe permanently wider. It is the most complete long-term fix. In congested regions, though, the timeline is set by the grid operator, not by you or your landlord.

A battery works like a water tank. It fills slowly from the grid or from solar panels, then releases a lot of power at once when trucks plug in. It works as soon as it is installed, and it keeps the site running if the grid goes down.

1. How much grid capacity does the site have, and how much of it is still unused?
2. Can the site send surplus power back to the grid, or only draw from it?
3. Are solar panels or a battery already installed?
4. Can the electrical installation grow step by step as the fleet grows?
5. If a grid upgrade is needed, how long will it realistically take, and who applies for it?

If most answers come back as ​“we would need to look into it”, your electrification plan carries real risk. A site with clear answers removes most of it.

WDP builds energy infrastructure into its warehouses: solar panels, batteries, energy management and EV charging. It does so through its Green Mobility Hub approach and offers EV charging stations across its European portfolio.

Nassau Sneltransport electrified its fleet this way without paying for the charging infrastructure itself. For Einride, WDP is building the Netherlands’ first dedicated charging plaza of its kind for electric trucks.

Want to go deeper? Read about depot charging versus en-route charging, why warehouses need battery storage for EV charging and build-to-suit versus an existing lease. Looking for a site? Raamsdonksveer already has battery storage and expandable power in place.

Fleet electrification succeeds or stalls on the power supply at the warehouse. Sites with spare grid capacity, battery storage and charging already in place offer the fastest and most predictable route. WDP builds that into its warehouses across Europe, so tenants can plan their electric fleet around what the site delivers, not around a grid operator’s waiting list.
