Square metres, and the power to go with them
What the warehouse of the near future looks like
Picture a logistics site as it will look five years from now. The roof is covered in solar panels. Autonomous robots move between the racks inside the hall. Eight electric tractor units are plugged in at the loading dock. Forty company cars are charging in the car park. In the office section, a heat pump has replaced the gas boiler.
All of it hangs off a single grid connection. And that connection has not grown with it.
Everything that is going electric
The electrification of logistics is usually reduced to electric trucks. That is the most visible part, but far from the largest.
Transport. Electric tractor units and vans, with charging infrastructure on site. Heavy freight does not need an ordinary charge point but fast chargers, drawing power levels a standard connection was never designed for. Add to that the electric terminal tractors moving around the yard all day.
Internal logistics. Forklifts and reach trucks now run on lithium-ion, topping up during breaks rather than swapping batteries. Alongside them come autonomous mobile robots, shuttle systems in the racking, automated sorting installations and robotic arms for picking and palletising.
The building itself. Gas heating gives way to heat pumps. Chilled and frozen storage is growing faster than the market average and is the heaviest consumer in the entire building. Reefer connections at the docks add another layer.
The workforce. This element is systematically underestimated in Belgium. Tax reform is pushing the company car fleet towards electric. Within a few years, a site with two hundred staff will not need ten charge points but several dozen. That is not a logistics decision; it is a car park problem with a power component attached.
And the servers. Warehouse management, image recognition on the sorting line, robotics control: part of that computing capacity is moving onto the site itself.
Each of these is manageable on its own. The sum of them is not.
Demand for power is growing faster than the grid
What users and owners are already seeing today is that the electrical capacity requested per site rises year on year. And that demand will keep climbing as fleets, internal logistics and heating electrify. A building designed ten years ago was designed for a consumption profile that no longer matches what a tenant will need tomorrow.
That growth is outpacing the build-out of the electricity network. Grid operators are investing heavily, but expanding infrastructure takes time while the electrification of demand moves ahead. Available power on a site therefore becomes a factor to account for in design, letting and redevelopment.
This is no cause for alarm. It is, however, a design question that did not exist a few years ago.
What the sector is doing about it
Solutions are being put in place to meet that growing demand, and battery storage is the most visible answer. The battery here is not a sustainability symbol. It is the component that makes the arithmetic work.
Major players such as Montea and WDP are installing battery storage on their sites, coupled to the rooftop solar panels and to an energy management system that controls the charge points. The logic is as simple as it is effective: these installations do not request additional grid capacity, they redistribute what is already available within the existing connection. Solar output peaks around midday, while fleets that return to site in the evening draw their energy mainly overnight. The two peaks do not coincide, and bridging that gap is exactly what the battery does.
The result is that more becomes possible within the same cable than the cable allows on paper.
In closing
The warehouse of the near future is no longer a box where goods wait. It is a node where flows of goods and flows of energy meet, with a roof that generates, a buffer that manages and a yard that charges.
That changes the question a tenant asks on a site visit. It used to be: how many square metres, and how quickly can I reach the ring road? Soon it will be: how many square metres, and how much power comes with them?
