Fleet charging looks like commercial charging and is engineered differently, because a fleet has a schedule. Vans that return at six in the evening and leave at six in the morning have twelve hours to share, which means load management can serve many more vehicles than there are full-capacity circuits. Vehicles that come and go all day cannot share, and the design has to assume simultaneous demand. Getting that distinction right is the difference between a service upgrade and no service upgrade, and it is worth more than any decision about hardware. So we start with the duty cycle: how many vehicles, when they park, how much range each one burns in a shift, and what happens on the worst day rather than the average one. From that comes the port count, the circuit layout, whether load management is viable, and whether the existing service carries it. Phasing usually follows, because most Boston fleets electrify a few vehicles at a time. Infrastructure gets sized for the eventual fleet and trenched once, with ports added as vehicles arrive, which costs slightly more now and far less than opening the pavement twice. Grant funding matters here: MassEVIP has a fleet track, and utility make-ready programmes cover infrastructure. Both need filing before the work starts.
A depot project runs: duty-cycle assessment, load study, layout and phasing plan, grant and make-ready filing, permit, trenching and infrastructure, ports, commissioning. We coordinate the utility's side against your operational calendar so the disruptive work lands when the yard is least busy. You get the assessment, the phased layout, the funding package, the permit and the commissioning record, plus the port count each phase adds. Where drivers take vehicles home rather than returning them to the yard, we scope those addresses separately, because a home install on a company vehicle is a different permit and a different rebate route.

Ports and circuits laid out around how the vehicles actually return and leave.
Service capacity and trenching dominate; the chargers are rarely the big number.
Infrastructure sized once, ports added as vehicles arrive in later years.
Ten services, from a single garage circuit to a commercial lot. The install work splits by what the panel can carry and by who owns the parking. Repair and maintenance keep an existing charger delivering full current instead of quietly derating.

Outside Boston we work in Cambridge, Somerville, Newton, Quincy and Medford. Each one files electrical permits through its own office and sits in its own utility territory, so the rebate route and the inspection timing shift from city to city. We confirm both before the first invoice.
Frequently Asked Questions
EV Charging can be complex, and we’re here to provide answers to common questions. Here are some frequently asked questions from our clients.
Most Boston home installs land somewhere between roughly $1,700 and $4,000, and the spread is almost entirely about the panel and the distance. A charger mounted beside an existing panel with spare capacity sits at the bottom of that range; a run to a detached garage, or one that needs a panel upgrade first, sits at the top. We price after we have looked at the panel and the parking spot, because a number given before that is not a quote.
Yes. A new charger circuit is electrical work, and Massachusetts requires that it be filed with the municipal wiring inspector before it gets energized. We pull the permit under our license and meet the inspector for the rough and final. If an installer offers to skip that step, the circuit never gets inspected and the paperwork you need for a rebate does not exist.
Not unreasonably. The Massachusetts Right-to-Charge law limits what a condo association can refuse when a unit owner wants a charger at their own parking space, though the association can still set reasonable conditions about routing, metering and insurance. What actually stalls these projects is incomplete paperwork rather than a flat refusal. We prepare the scope drawing, the equipment specification and the electrical detail the board needs to vote on.
Sometimes, and it comes down to the load calculation rather than the age of the panel. A 100-amp service with electric heat or a large air conditioner often has no room for a 40-amp charger circuit, while another 100-amp house has plenty. We run the calculation during the site visit. Where the load is tight, a load-management device can occasionally solve it for less than a service upgrade would.
The state runs MOR-EV, the utilities run charger and make-ready rebates through Mass Save, and MassEVIP grants cover charging at multifamily buildings, workplaces, fleets and public sites. The federal residential charger credit ended on June 30, 2026, so a charger placed in service after that date does not qualify. Amounts and eligibility change, so we confirm what your address and utility actually qualify for before you commit to equipment.
The wiring on a straightforward residential install is usually a single day. What sets the overall timeline is the permit and inspection sequence, equipment lead time, and any utility work if the service itself has to change. A condo or commercial project adds the approval step ahead of all of that. We give you the sequence in writing, with the inspection date, so you know what is waiting on us and what is waiting on somebody else.
Usually fewer than there are vehicles. If the fleet parks overnight, load management lets vehicles take turns on shared capacity and still be full by morning. If vehicles cycle through during the day, that does not work and the count rises toward one port per vehicle. The duty cycle decides it.
Yes, and it is usually the right approach as long as the infrastructure is sized for the eventual fleet now. Conduit, service capacity and trenching are the expensive parts and they should be done once. Adding ports to infrastructure that was already sized for them is a modest job.
MassEVIP includes a workplace and fleet track, and the utilities run make-ready programmes that fund the infrastructure side. Eligibility and amounts change, and both routes need to be filed ahead of construction rather than claimed afterwards. We check what your site qualifies for during the assessment.
For anything beyond a handful of vehicles, usually yes, because scheduling and load management depend on the units talking to each other. That brings a subscription and a data connection into the project. For a small depot with a predictable overnight pattern, simpler hardware can be enough.
