EV Charging in an Apartment: What “Provision” Means

A buyer hears "EV charging provision" and pictures a charger on the wall beside their parking bay. A developer says it and may mean a conduit cast into a slab. Neither party is lying and the gap between them will be discovered somewhere around the second year of the residents' association, at which point it becomes an expensive collective problem.

The gap is entirely knowable before you book, and this is the list of questions that closes it.

Four things "provision" can mean

All four are described in marketing with the same phrase. Only the last is what most buyers hear.

Sanctioned load is the constraint everything follows from

A residential community's electrical supply is sanctioned at a particular load by the distribution licensee — in Bengaluru, BESCOM — and the transformers, cabling and switchgear are sized to that sanction. Charging is an unusually heavy and unusually concentrated addition to it, because cars charge at the same hours that lifts, pumps, lighting and every household's evening peak are already running.

If load was earmarked for charging at design stage, adding points later is a wiring job. If it was not, adding points later means applying for enhanced load, potentially upgrading the transformer and the panel, and finding the money in a corpus that was never sized for it. That single design decision, made before the first slab was poured, determines whether a community gets charging in year three or argues about it for a decade.

So the question is not "are there points?" It is "was load earmarked for charging, and how much of the total sanction is it?"

Where the cable runs, and why retrofitting a basement is expensive

Running power to a parking bay in a completed basement means core-cutting or surface-routing through a structure designed without it, working around ventilation ducts, sprinkler mains and drainage that already occupy the soffit, and satisfying the fire and safety requirements that apply to a basement full of parked vehicles.

It is also the kind of work that has to be done once, properly, for the whole level — because the second and third rounds of it, done piecemeal as individual residents buy cars, produce a basement ceiling nobody can maintain. This is why a community's charging story is really a story about whether the containment was thought about at design stage.

Metering and billing: the three models

• Back to your own flat meter. Cleanest billing — you pay for what you use, on your own bill. It needs riser capacity from your flat to the parking level, which is a design-stage decision and rarely retrofittable at scale.
• On the association's common meter, with sub-metering. Common in practice. Each point has a sub-meter, and the association recovers what each resident used through the maintenance account. It works when the sub-metering and the recovery process are set up properly and generates disputes when they are not.
• A third-party charging operator. An operator installs, owns, meters and bills for the points under an agreement with the association. It removes the capital cost and the operating burden and introduces a commercial counterparty, a tariff you do not set, and a contract that will one day need renegotiating.

Tariffs for charging are set by the state electricity regulatory commission and revised by order, so the number that matters is whichever is current when you are billed — not one quoted at a sales counter.

Who owns it, who maintains it, who is liable

Three questions that are almost never asked at booking and are the source of most of the friction later.

Ownership. Is the charger the resident's, the association's, or the operator's? A resident-owned charger on a common-area wall raises an immediate question about whether the association permitted the installation and on what terms.

Maintenance. Chargers fail. Who is called, on what response time, and out of whose budget?

Liability. Charging equipment in a basement is an electrical and a fire question. Earthing, residual-current protection, cable rating, isolation, and how the installation sits with the building's fire strategy are all engineering decisions with consequences, and the community's insurance position depends on them having been made properly.

The regulatory frame, named rather than quoted

Three sources govern this area and all three are revised, which is why they are named here rather than summarised.

• The Ministry of Power's guidelines and standards for electric vehicle charging infrastructure, which set the national frame for charging installations and are amended from time to time.
• The state's electric vehicle policy, which sets the local ambition and any facilitation attached to it.
• The state electricity regulatory commission's tariff orders and supply code, which govern connection, metering and what charging electricity costs.

Anyone quoting you a requirement from these should be able to say which document and which version. If they cannot, the right response is to go and read the current text rather than to argue.

The seven questions to put to a sales team

1. How many parking bays are provisioned for charging, and where are they? A number and a location on a drawing, not a gesture at the basement.
2. Was electrical load earmarked for charging in the sanctioned load, and how much? The single most consequential answer on this list.
3. What is physically installed today — conduit, cable, board, point? Map the answer onto the four rows in the table above.
4. How will a point be metered, and who bills me? Own meter, association sub-meter, or operator.
5. Can I have a point at my own bay, and what does the approval process look like? Ask what happens if half the community asks in the same year.
6. Who owns and maintains the equipment after handover? Developer, association, or third party — and under what agreement.
7. Which of these answers appears in the specification annexure to the agreement? The question that turns all six previous answers into something you can rely on.

A real answer is specific and bounded. "Provision is there" is not an answer to any of the seven.
