Your next phase of electrification
The first electric trucks may fit.
A different charging plan could make room for what comes next.
A truck that can do the route is only the start. The infrastructure, connection and running costs have to work too. TOGL is being developed to improve the parts of that equation a charging plan can change.

A different plan

Not yet
The current plan does not fit.
Some depots need a different charging plan. Others need changes to routes or infrastructure. An assessment shows which constraints can move.
These are starting points for assessment, not a claim that every depot can become viable.
01 / Start with the deployment
Electrification is a big commitment. You need the vehicle, the infrastructure and the running costs to make sense together, with enough charging time to do the work. Often, most of the pieces fit. One or two hold the decision back.
Compare costs over the same ownership period, including maintenance and service fees. Then check that the routes and available charging time work.
Green / Ready now
The deployment makes sense on its current assumptions.
Amber / A different plan
The trucks can do the work. The energy and connection costs hold the case back.
Red / Not yet
The proposal needs a more fundamental change before it can work.
Illustrative examples, not assessments or a scoring system. One critical constraint can stop a deployment; a red case does not need to fail every check. Different routes or expansion phases at one depot can sit in different groups.
The amber opportunity
TOGL does not change the truck’s purchase price. It is being developed to reduce charging costs and make better use of the supply you have. Those improvements could help a difficult overall business case become workable.
02 / Inside an amber depot
In developmentImagine a distribution depot planning its next electric trucks. Vehicles return in the afternoon and leave the following morning. Charging them all together would exceed the available supply. Could using more of their time on site make the proposal workable?
The initial proposal
Too much requested at once for the available supply.
A different plan
Same energy requirement. Lower simultaneous demand.
Illustrative, not a customer case study or a measured result. Equal blocks represent equal energy requirements. This simplified example assumes compatible charging equipment, sufficient time on site and a supply that can serve one group at a time. The initial proposal cannot run as drawn. A real plan must account for each vehicle’s charging rate, other site demand and route energy needs, including an agreed reserve.
Scheduling may reduce the connection capacity a proposal needs. To add further trucks, assess their additional energy and charging time separately. A better schedule does not create unlimited capacity.
03 / Build the plan around the shift
Move charging into lower-cost hours where the shift allows.
In developmentShare available power as vehicle needs and site demand change.
In developmentAdjust eligible charging for potential income, with the next shift taking priority.
PlannedBack at the depot
The driver returns the vehicle and connects it for charging.
Before the next shift
Departure times and the energy needed for each route set the requirements.
While vehicles are parked
TOGL is developing charging plans around site limits and tariffs, with earlier departures taking priority.
Time to leave
The aim is enough energy for the work and an agreed reserve. A full battery is not the only useful target.
04 / Look beyond the truck price
The vehicle is one part of the investment. Compare the same routes, workload and ownership period, including the infrastructure and the cost of running it.
Getting the depot ready
Vehicles, development work, grid connection, civils and charging equipment.
A charging plan may change the capacity required and whether an upgrade can be deferred or avoided.Keeping the fleet working
Finance, electricity, maintenance and software or service fees.
Charging at lower-cost times may reduce the energy bill where the operating window and tariff allow.TOGL focuses on what the charging plan can change. Infrastructure delivery, private-wire projects and changes to routes require separate assessment and delivery arrangements. An avoided upgrade is a capital benefit, not an annual saving.
05 / Make the uncertainty smaller
You are committing capital and putting a working fleet on the line. A useful business case shows which costs could fall, how often the benefit could recur and what happens if the assumptions change.
Capital / Assess the requirement
Test whether the charging plan reduces the connection capacity required. Confirm any revised infrastructure scope and quotation before counting an avoided cost.
A project benefit, counted once.Recurring / Model, then measure
Estimate charging costs using your tariff and working pattern. A pilot can compare the plan with actual charging records and test how savings vary with use.
A repeatable opportunity, not a fixed payment.Additional / Keep it separate
Eligible responses to the grid may bring income. Show that separately from the core charging case, after participation costs and fees.
PlannedPotential upside, dependent on market access.Test the case on a harder day, too. A later return, a higher energy requirement or a different tariff can change the result. Understanding that range helps you judge the risk before expanding.
TOGL depot optimisation is In development and closed pilots are underway. These are benefits to investigate, not measured savings or guaranteed returns. Explore planned grid flexibility.
One depot or a whole portfolio
At one depot, explore how much further your existing connection and charging window could go. Across a portfolio, apply the same thinking to more sites and see where a different plan could make the next investment work.

Explore a different plan
Start with the initial proposals. Some already work; others are held back by charging costs, connection requirements or more fundamental constraints.

FAQ
An electric truck depot assessment should bring together vehicle and charger requirements, route energy needs, return and departure times, available site capacity, electricity tariffs and the whole investment. TOGL pilot conversations explore what a charging plan could change. Depot optimisation and eHGV support are in development.
A depot charging plan may defer or avoid a grid upgrade where the available supply and charging window can meet vehicle energy needs alongside other site demand. TOGL is developing this capability. A plan cannot provide missing power, and any revised infrastructure requirement needs site-specific assessment.
The TOGL depot map and charging diagrams are illustrative scenarios, not measured customer results or savings forecasts. The map uses fictional depots. Capital benefits, recurring charging savings and potential flexibility income need separate assessment; grid market participation is planned.
