Fleet electrification · depot by depot

Will your depot's electrical service survive the day the whole fleet plugs in?

We model your worst plausible charging day against your real service limits, and show you what breaks, where, and by how much, before the capital is committed.

Bring your fleet size and your utility bill. We'll tell you on the call whether your service can take the load. No deck, no pitch.

The questions on the table

The five questions a depot electrification plan has to answer.

"Will the grid hold?"

We locate the breach: which electrical node fails, by how much, and when in the day and season.

"Do I need the $2M service upgrade, or can I avoid it?"

Compare upgrading the service against on-site storage and phasing the rollout. Each option is feasibility-checked, with sourced, dated cost and lead-time.

"Can these buses actually do their routes?"

We flag the battery-vs-route constraint honestly, at the aged, end-of-life pack rather than day one, before you commit to procurement.

"What does this cost me every month?"

Directional demand-charge exposure, tied to the peak that causes it, from sourced, dated utility rates.

"Prove it to my board and my utility."

A print-ready evidence pack where every figure traces to its source, built to justify a service-capacity review with your utility and a licensed engineer.

The problem

Electrifying a depot is a multi-million-dollar bet on electrical capacity.

And the expensive failures stay invisible until it's too late. A plan that's fine on a spreadsheet fails the morning the whole fleet returns, plugs in on a cold day, and peak load runs past what the site's electrical service can deliver. You only find out early if someone stress-tests the plan against the depot's real limits. That's what BEV Ready is: an independent referee, not an optimizer and not a vendor with hardware to sell.

A missed peak is not a rounding error. Utility service upgrades run $1–3M with 12–18-month lead times, and the depots that discover the breach after ordering buses pay for both the upgrade and the delay.

The power crunch

The grid is full. Your fleet is in line behind the data centers.

Electrifying a depot used to be a vehicle problem. Now it's a power problem, and you're competing for that power with the largest, best-funded buyers in history. The winners this decade won't be the fleets that ask for the most electricity. They'll be the ones that prove they need the least.

~2,000 GW

waiting in the U.S. interconnection queue at end of 2025, about 2× the entire existing U.S. power plant fleet.

8+ years

average interconnection wait in PJM in 2025, up from under 2 years in 2008.

6 months

to take delivery of the buses those chargers are meant to serve.

>60%

reduction in grid capacity required per vehicle achievable through smart depot management.

That's what the Depot Digital Twin does: it finds the smallest grid connection that still runs your fleet, before you get in a queue you can't afford to lose.

It finds your true managed peak, not the naive nameplate sum, but a defensible number your utility can act on: the one that gives you the strongest case for a flexible interconnection, or a connection the utility can grant on existing capacity.

01 · Screen

Free feasibility check

A fast, free first look at a depot: energy demand, peak load, the utility service tier you'll likely need, and directional cost exposure, in minutes rather than a multi-week study. Enough to know whether a depot is worth pursuing before you commit the capital.

● Free · live now
02 · Plan

Depot digital twin

Engineer-led · you keep the keys

A BEV Ready engineer builds your depot's twin with you: every charger, circuit, vehicle, and the electrical service feeding them. It runs your real duty cycles against your real limits, shows exactly where the plan falls short, then hands you the keys. You keep a living model you can plan and operate with, not a static report that's stale the day it lands. The pilot simulator takes it past the worst day to a full operating week, covering V2L, storage, and constrained-grid windows.

● Engagements open Start your depot twin
03 · Rehearse

Go-live rehearsal

Run your go-live before go-live. Your depot's twin plays the day: cold snap, late arrivals, a cabinet down, and you watch the plan break safely, before a single bus depends on it. Builds on the pilot simulator you already have.

◐ In development · included in early deployments
04 · Operate

Depot orchestration

The model that approved your depot watches it live: modeled vs. metered, drift alerts before the breach, and eventually the controls.

◐ In development · early-access waitlist

Across all four stages, BEV Ready engineers are involved; the software's job is simply to tell you when that conversation is worth having.

BEV Ready fits in the evaluation stage of a fleet electrification plan, after you've defined the strategy and inventoried the fleet, and before you commit to hardware or a utility application. It surfaces what will and won't work; then, if the stakes justify it, our engineers help you take the answer to a stamped design.

In development

The model that approves your depot will run it.

Every depot twin we build becomes an operating envelope. The orchestration layer, still in development, watches your live depot against it: modeled vs. metered, headroom alerts hours before a breach ("tonight's plug-in pace crosses your service limit at ~19:40"), and a rehearsal mode that certifies every capability in simulation before it ever touches your hardware.

The toolbox

What does the depot digital twin do?

The free feasibility check is live now. The rest is the engineer-led depot twin, built with you and owned by you.

Every run answers three questions, separately, never merged: Capability: can each vehicle physically do its shift? Delivery: under your electrical limits, did every vehicle get its energy? Charging Capacity: does any node exceed its rating, and when?

Feasibility & simulation

Worst-plausible-day and operating-week modeling against your real electrical limits, covering feasibility, CC-CV charging, seasonal presets, and an uncertainty band.

Cost & financial

Demand-charge exposure, a 20-year proforma, and scenario comparison, with every figure traced to a named assumption.

Resilience & lifetime

N-1 and backup-duration checks, plus how the fleet ages across its service life.

Why it's defensible

Honest by design. Independent by default.

Every number traces to a named assumption.

No hidden buffers, no flattering averages, no faked precision. When something breaks, we show you where and why. When it holds, we show you that too. Export the evidence straight into your procurement file or board pack.

We model your transition, and we don't sell you chargers.

Independent and vendor-neutral: your number isn't coming from someone with hardware to move. Today the model advises; it never silently acts. As the orchestration layer ships, every action it takes will trace to a verdict you can audit: the model shows its work whether it's planning your depot or running it.

Physics-based, grounded in peer-reviewed research.

Every number rests on established engineering science, not rules of thumb or vendor guesswork.

How the model works.

The engine is physics-based, grounded in peer-reviewed engineering science rather than rules of thumb. It stays directional and capacity-level, modeling a single worst-plausible day or a representative operating week. That makes it sharp enough to decide service upgrades, BESS sizing, and charger counts, not a billing-grade or stamped study.

Who we work with

Honest scope

What the digital twin is and isn't.

It's a capacity-level, directional model. The feasibility screen models a single worst-plausible day; the operating-week view simulates a multi-day representative week. Both are directional, sharp enough to decide service upgrades, BESS sizing, and charger counts. It is not a billing-grade, stamped, or "optimal" plan. The financials (20-year TCO, NPV, payback) are directional, named-assumption estimates you can re-run with your own inputs, not a guaranteed bill or investment advice. A BEV Ready engineer builds and validates it with you, then hands you the keys. You keep a living model that gets more accurate the longer it's used. It feeds your engineer, utility, and board; it doesn't replace the licensed PE who stamps the design.

What we do, and where the consultancy takes over.

The tool models the technical decision: what capacity, what chargers, what schedule, what it costs. The other half of an electrification project (stakeholder alignment inside your organization, workflow changes for your ops team, training for your drivers and technicians) is where the engineering consultancy engages. We paired the two deliberately: software for the early technical questions, engineers for the organizational and technical questions that follow.

Case studies

Six real depots, re-modeled against the published record.

Not illustrative scenarios. These are published transit electrification studies, rebuilt end-to-end in the twin and run against their own worst plausible day, then compared to what the original researchers found. Every number traces to a source you can read yourself.

Hamburg Alsterdorf · 127 buses

Finding the real peak behind a 127-bus fleet

The naive answer (127 buses × 150 kW chargers = 19 MW) is almost never right. Modeled managed-charging peak came in at 4,538 kW, leaving 3× headroom on a 20 MW service. Benchmarked against Jahić, Eskander & Schulz (2019).

Delhi Transit Network · 50 buses

Answering "what if a charger fails?" before it happens

An N-1 charger loss costs 10.0% of delivered charging energy and strands 5 of 50 buses. In a full grid outage, the depot carries a 500 kW critical load for 4.5 hours without stranding a single bus. Benchmarked against Sharma & Nezamuddin (2026).

FAQ

Fleet depot electrification, answered.

How do I know if my depot can support EV charging?

Run the free feasibility check. It models your fleet's worst plausible day of charging against your site's real electrical limits and reports energy demand, peak load, the utility service tier you'll likely need, and a directional cost range: enough to know whether a depot is worth pursuing before you commit the capital.

What is a fleet depot digital twin?

A depot digital twin is a model of your depot (every charger, circuit, vehicle, and the electrical service feeding them) that a BEV Ready engineer builds with you. It runs your real duty cycles against your real electrical limits to show exactly where and when a charging plan would breach service capacity, then hands you the keys. You keep a living model you can plan and operate with, not a static report.

What is the free feasibility check?

The free feasibility check is a fast first-pass screen for a depot (energy demand, peak load, the utility service tier you'll likely need, and a directional cost range) delivered in minutes, not over a multi-week study. It tells you whether a depot is worth pursuing.

Is BEV Ready a stamped engineering study?

No. BEV Ready is a capacity-level, directional model: sharp enough to decide service upgrades, storage sizing, and charger counts, but not a billing-grade or stamped plan. It feeds your engineer, utility, and board; it doesn't replace the licensed PE who stamps the design.

Is BEV Ready independent, and do you sell chargers?

No. BEV Ready is independent and vendor-neutral, and we don't sell you chargers, so your numbers aren't coming from someone with hardware to move. We model your transition: today the model advises and never silently acts, and as the orchestration layer ships, every action it takes will trace to a verdict you can audit.
