Your sort schedule runs the building.
Your energy doesn't know that.
A logistics depot spends $30,000–120,000 a month on electricity — sort conveyors, cold zones, dock HVAC, warehouse lighting, and now EV fleet charging. Energy follows the operation: parcels arrive, the sort kicks off, trucks leave. But there is no energy function. The operations team manages the sort. The facilities team manages the equipment. Nobody connects the sort schedule to the demand peak. The sort starts at 6am. Every load in the building peaks simultaneously. That spike sets the demand charge for the entire month. Nobody coordinates. Nobody even sees the connection.
Model your depot economicsOne spike during the sort
sets the bill for 30 days.
Your demand charge is based on the highest 15-minute peak in the month. At a logistics depot, that peak almost always happens during the sort — conveyors running, dock doors open, HVAC compensating, cold zones working hard, lighting at full. One spike. One sort. Bill locked for 30 days.
Now add EV fleet charging. Your sustainability commitment says 50 electric vans by 2028. Those vans return between 5pm and 7pm. They all plug in at once. 50 trucks at 7kW each is 350kW of additional demand — on top of the existing peak. That's not an energy problem. That's a grid infrastructure crisis.
The grid upgrade: $200,000–500,000 per depot, 18–36 months. At 15 depots: $3–7.5M before a single truck charges.

Your energy signature is your sort schedule.
But your energy system can't read it.
A logistics depot's energy signature tells the story of its operations. The 6am spike is the sort starting. The 7am–2pm plateau is steady-state. The 3pm dip is the gap between sorts. The evening ramp is the return sort plus — increasingly — EV fleet charging.
Wattif reads this signature in real-time. It knows when the sort is running from the load pattern. It sees the HVAC compensating for open dock doors. It catches the cold zone compressor running during the gap when it shouldn't be.
Across 15 depots, the pattern intelligence surfaces which facilities are efficient, which are wasteful, and why.
Pre-cool before the sort. Stagger the docks.
Charge 50 trucks on time.
Operations-aware coordination
The sort is sacred — no energy action can delay a parcel. Wattif optimizes everything around it. Pre-cool cold zone an hour before sort. Stagger dock door HVAC. Dim warehouse lighting in inactive zones. Shift non-critical loads to off-peak. The sort runs exactly as planned. The demand peak drops 20–30%.
EV fleet intelligence
Every truck has a deadline. Van 12 leaves at 4am. Van 37 doesn't leave until 7am. Van 5 came back with 60% charge; Van 22 is nearly empty. Wattif knows the dispatch schedule, each vehicle's state of charge, and the depot's current load. It builds a charging plan that gets every truck charged by its deadline while staying under the demand limit. 50 trucks charged on time. No grid upgrade.
Operational context
This is what makes Wattif different. It connects to operational systems — warehouse management, fleet dispatch, sort scheduling. An energy action that delays a parcel is a failed energy action. Wattif never makes one.

One depot shaves the peak.
15 depots change the fleet transition plan.
Every depot optimized frees capacity for EV charging. Every grid upgrade avoided is $200K–500K redirected to more vehicles, more chargers, more routes.

“We were told we needed $4.2M in grid upgrades to charge our electric fleet. Wattif showed us we could charge 40 vehicles per depot within existing capacity by coordinating with the sort schedule. We've deployed chargers at 8 depots without a single grid upgrade.”
