How real deployments are put together

The constraints, the decisions and what changed — written for operators evaluating whether the same approach would work for them.

Highway & fuel retailComposite scenario

Cutting field dispatches in half on a 46-connector highway corridor

A corridor operator with sites spread over 600km of national highway rebuilt its fault-handling around remote triage — and stopped driving to reset chargers.

National highway corridor, North India

  • 46

    DC connectors across 17 sites

  • 600km

    Corridor length

  • ~4 hrs

    Average drive time to a site

Retail & shopping centresComposite scenario

Automating revenue share across a 12-property retail portfolio

Twelve malls, twelve different revenue-share agreements, and a finance team spending a week a month on statements nobody trusted.

Tier-1 and tier-2 cities, West India

  • 12

    Properties under one operator

  • ~1 week

    Finance time per month, before

  • 3

    Different revenue-share structures

Fleets & logisticsComposite scenario

Fitting a full depot behind an existing sanctioned load

Adding buses meant either upgrading the connection — eighteen months and substantial capex — or making the existing one go further.

Municipal depot, South India

  • 28

    Buses charging overnight

  • 1

    Sanctioned connection, unchanged

  • 4 hrs

    Departure window every morning

New CPOComposite scenario

From installed hardware to paying drivers in six days

Eight connectors, no software team, and a loan repayment schedule that started before the chargers did.

Tier-2 city, North India

  • 8

    Connectors at launch

  • 6 days

    Hardware connected to first paid session

  • 0

    Software engineers on the team

eMSPComposite scenario

Building an eMSP on roaming connections rather than capital

A fleet-card business already had the drivers. What it did not have was a charging network — and no intention of building one.

Multi-state, West and South India

  • 0

    Chargers owned

  • 6

    Roaming partners connected

  • 1

    Invoice per fleet, per month

Charger OEMComposite scenario

Shipping hardware with a platform already attached

Every buyer asked "what software runs it?" and the answer was always somebody else. That answer was costing the recurring revenue.

Manufacturing in North India, buyers nationwide

  • 2

    Product lines, AC and DC

  • 1

    Tenant provisioned per buyer

  • 100%

    Under the manufacturer’s brand

Hotels & hospitalityComposite scenario

Guest, staff and public charging on the same eight bays

Charging was installed because guests asked. Two years later nobody could say whether it was earning or losing.

Nine properties, North and West India

  • 9

    Properties

  • 3

    Audiences on the same hardware

  • 0

    Dedicated headcount

Fleets & logisticsComposite scenario

Low-power charging at the volume India actually runs on

The segment that dominates Indian electrification is three-wheelers — and almost nothing in charging software is built for it.

Four hubs, National Capital Region

  • 140

    Three-wheelers

  • 4

    Hubs

  • 2

    Shift changeovers a day

Utilities & discomsComposite scenario

Public charging under a tender, with the reporting it demands

Subsidised public charging comes with reporting obligations. They are discovered late, and reconstructing them from incomplete records is painful.

Public charging under a state tender

  • 38

    Public sites under the tender

  • Quarterly

    Reporting obligation

  • Per site

    Granularity required

Housing societiesComposite scenario

Resident charging billed to the flat, not to the sinking fund

Sixty residents with EVs, one common electricity meter, and a managing committee meeting that came round every month.

Gated community, Tier-1 city

  • 60+

    Resident EVs

  • 1

    Common connection

  • Monthly

    Billed with maintenance

Scaling CPOComposite scenario

Territory-scoped operations across 240 connectors

Individually every charger was manageable. Collectively they produced more exceptions per day than the team could chase.

Four states, North and Central India

  • 240

    Connectors

  • 4

    States

  • 5

    City managers

Parking operatorsComposite scenario

Charging in a car park where the average stay is four days

Airport parking inverts every assumption in charging: the dwell time is enormous, and that is the problem rather than the opportunity.

Long-stay car park, major airport

  • 4 days

    Average stay

  • 18

    AC bays, 2 DC

  • 24×7

    Arrivals and departures

Scaling CPOComposite scenario

Repricing 60 connectors on evidence rather than instinct

The headline rate was competitive and the sites were busy. Realisation per kWh was still well below what the tariff implied.

Two metros, South India

  • 60

    Connectors repriced

  • 3

    Time-of-day windows

  • 0

    Change to the headline rate
