MegaWatts Depot provides Charging-as-a-Service for delivery, rental, rideshare, transit and municipal depots with 100 or more vehicles. Mobile 700 kW to 1 MW+ blocks with on-board storage power DC dispensers on site in days, with energy, maintenance and 24/7 monitoring included under a written SLA, billed per kWh or per dispenser at a rate set in your quote.
The depot problem
The vehicles were approved in one budget cycle. The interconnection will take three.
Depots electrify faster than utilities can serve them. A 150-van depot needs 1–2 MW at night; a typical service upgrade runs 3–18+ months and major grid work 18–36. The vans are already delivered.

FAQ
Depots questions, answered.
What happens when our utility upgrade finally arrives?
The blocks leave or stay as backup. Exit terms for an early utility go-live are set in your agreement, so there is no stranded asset.
Do you need a permit at our depot?
Usually a temporary electrical permit for the dispensers, which we file. No trenching or switchgear changes inside your building.
How loud is it?
Battery-quiet at the dispensers. Any generation runs enclosed at the far side of the pad.
Is there an upfront cost?
There's no published rate for Charging-as-a-Service. Billing runs per kWh or per dispenser per month at a rate set in your quote.
What term do you require?
Term length is set in your quote, from a short pilot up to a multi-year agreement.
Can you scale as we add vehicles?
Yes. Add a block or a dispenser lane in days, not another interconnection application.
