Sanctioned load is the maximum electrical demand — measured in kilowatts (kW) or kilovolt-amperes (kVA) — that your electricity distribution company (DISCOM) has approved for your connection. It is printed on your electricity bill, usually near your consumer details. An EV charger is one of the largest continuous loads most households ever add, so before installing one you need to check whether your sanctioned load has enough headroom for the charger on top of your normal evening usage. If it does not, you apply to your DISCOM for a load enhancement — usually a routine process, but one to complete before the charger goes in, not after your supply starts tripping.
What sanctioned load actually means
Think of sanctioned load as the width of the electrical pipe into your flat, not the amount of electricity flowing through it. Your monthly bill measures consumption in units (kWh). Sanctioned load is the peak demand you are permitted to draw at any one moment, and the DISCOM sizes your meter, service cable and its local network around that figure.
It is effectively a contract. In many tariff structures part of your fixed monthly charge is linked to it, and the transformer serving your building is planned around the combined sanctioned load of all connected flats — which is why adding a large new appliance touches shared infrastructure, not just your own wiring.
Where to find it on your electricity bill
Look near your consumer number and address at the top of the bill. Depending on the DISCOM it may be labelled "Sanctioned Load", "Contracted Load" or "Contract Demand", in kW or kVA. Some bills also show "Connected Load" — a different figure, covered in the questions below.
If your bill does not show it clearly, most DISCOMs let you check through their website, app or customer-care line using your consumer number. In an apartment there are usually two kinds of connections: your flat's own meter, and the society's common-area connection running lifts, pumps and passage lighting — each with its own sanctioned load. Which one matters depends on where the charger will draw power from, a question worth settling early if you are still weighing private versus shared charging in your parking area.
How much headroom does an EV charger need?
A home EV charger draws its full rated power continuously for hours — quite unlike a geyser that runs in short bursts. Home chargers are commonly rated around 3.3 kW; faster wallboxes around 7.2 kW. If you are unsure which suits your vehicle and parking, our comparison of 3.3 kW versus 7.2 kW charging for apartments walks through the trade-offs.
Here is an illustrative example — round numbers for reasoning, not a quote. Say your flat's sanctioned load is 5 kW (check your own bill). On a summer evening, an air conditioner, refrigerator, lights and a geyser might together draw 3 to 4 kW. Add a 3.3 kW charger and demand could touch 7 kW — well above the sanctioned 5 kW. But charge after midnight, when only the fridge and a fan are running, and the same charger may sit comfortably within the limit. This is why a good assessment looks at when you will charge, not just what you will install.
| Your situation (illustrative) | What it suggests | Sensible next step |
|---|---|---|
| Sanctioned load comfortably exceeds your evening peak plus the charger's rating | Headroom likely exists | Have an electrician confirm; an enhancement may not be needed |
| Headroom exists only if you charge overnight | Workable with discipline | Ask about scheduled charging or a charger with adjustable current |
| The charger's rating alone is close to your sanctioned load | Enhancement very likely needed | Apply to your DISCOM before any installation work |
| Bill is unclear, or the charger will run off the society's common supply | Key facts are missing | Get the figure from your DISCOM and open the discussion with your RWA |
How an electrician assesses your load
A licensed electrician will not simply add up appliance ratings. A proper assessment usually covers five things:
- Bill and meter details — your sanctioned load, meter capacity, and whether the connection is single-phase or three-phase.
- Realistic peak demand — a judgement of which loads actually run together, rather than a total of every nameplate (engineers call this a diversity factor).
- The physical path — the main switch and MCB ratings, the condition and size of wiring from your meter to the parking spot, and the quality of earthing, which matters as much as capacity.
- Charger-to-connection fit — higher-power wallboxes generally expect a three-phase supply, so a single-phase flat may be better served by a smaller unit.
- A recommended path — install as-is, install with overnight or reduced-current charging, or apply for a load enhancement first.
The visit usually takes under an hour and pairs well with the wider site survey in our guide to installing an EV charger in an Indian apartment. For a quick first pass, try the apartment EV readiness checklist.
Applying for a load enhancement: the general process
If the assessment shows you need more headroom, the remedy is a load-enhancement application. The broad sequence is similar across the country, though forms, charges and timelines differ — confirm specifics with your own DISCOM:
- Apply online or at the local DISCOM office, quoting your consumer number and the additional kW you need.
- Submit the documents your DISCOM asks for — commonly identity and occupancy proof; some societies also expect an RWA no-objection.
- Pay the applicable charges, which vary by DISCOM and by how much extra load you request.
- The DISCOM may inspect the premises and, where needed, upgrade your meter or service cable before approving the revised load.
Treat the enhancement as one line in a larger budget that also includes wiring, a dedicated MCB and possible civil work — the apartment charger cost calculator helps you frame the full estimate.
What happens if you skip this and overload
Exceeding your sanctioned load is not merely a paperwork problem. The immediate symptom is nuisance tripping — the main MCB cutting out mid-charge, often at night. More seriously, wiring sized for the old load can overheat when pushed hard for hours, and overheated cable in an enclosed basement is a genuine fire hazard. Some tariff structures also let the DISCOM levy penal charges when recorded demand repeatedly exceeds the sanctioned figure — ask yours how it treats this. And within a society, an incident traced to an unapproved, overloaded installation can quickly become a dispute with the RWA. Our apartment EV charging safety checklist covers the wider checks that keep an installation defensible.
Common questions
Is sanctioned load the same as connected load?
No. Connected load is the sum of the rated capacity of everything wired in your premises; sanctioned load is the maximum demand the DISCOM has approved you to draw. Bills sometimes show both, and DISCOMs use the terms slightly differently, so check how your own bill defines each.
Do I need a load enhancement for a 3.3 kW charger?
There is no universal answer. Many flats have enough headroom for a 3.3 kW charger used overnight, but it depends on your sanctioned load, your other appliances and your charging window. Treat a licensed electrician's assessment as the deciding word, not any rule of thumb.
Will enhancing my load increase my monthly bill?
It can. In many tariff structures the fixed or demand component of the bill is linked to sanctioned load, so a higher figure may raise your fixed charge even before you use a single extra unit. Ask your DISCOM what the revised fixed charge would be.
Can the charger run on the society's sanctioned load instead of mine?
Only with the society's agreement. A charger fed from the common-area supply draws on the society's connection and appears on the society's bill, so the RWA must consent and a fair recovery arrangement must exist. The society may also need to check its own headroom, exactly as a flat would.
Sanctioned load is a solvable constraint, not a roadblock — but it is one of the few parts of an EV installation you cannot judge by eye. Before buying a charger, have a licensed electrician evaluate your connection and wiring, and confirm the current requirements, charges and application steps with your own DISCOM. Their word on your specific meter outranks any general guide, including this one.
