Load Extension

Raising the sanctioned load on an existing connection — the application, the infrastructure it triggers, and getting off a penal tariff before it costs another quarter.

  1. 01 Load audit
  2. 02 Application
  3. 03 Feasibility
  4. 04 Revised estimate
  5. 05 Infrastructure
  6. 06 Revised sanction

Sanctioned load is what you agreed to draw, not what your equipment can draw. Plants grow — a compressor here, a second line there — and the sanction quietly stops matching reality. The DISCOM notices through the maximum demand recorded on your own meter, and the correction arrives as a penal tariff rather than a reminder.

A load extension is the fix, and it is worth doing deliberately rather than reactively. The first question is not how much more you need this year, but whether the number you apply for takes you across the LT ceiling — because if it does, the application stops being a load extension and becomes an HT connection, with drawings, an agreement, a substation and a statutory approval behind it.

We audit what you actually draw against what you are sanctioned for, work out the right number to apply for, file it, follow the feasibility and the revised estimate, and build whatever the sanction turns out to require — a larger transformer, an upgraded cable, or the full HT changeover.

SANCTIONED TODAY WHAT YOU ACTUALLY DRAW THE GAP THAT NEEDS SANCTIONING SANCTIONED LIMIT DRAWING ABOVE THE LIMIT = PENAL TARIFF, NOT A WARNING BIGGER TRANSFORMER CABLE / LINE UPGRADE LT MOVES TO HT

The gap between the sanction and the draw is what you are applying for — and how big you make it decides whether this stays a paperwork job or turns into a transformer, a cable upgrade, or a move to HT.

The Route

Application To Charging

Who holds it at each stage, and what has to be true before it moves on.

  1. Us

    Load audit

    Recorded maximum demand read off the meter and the bills, compared against the connected load and against what is genuinely planned. The applied figure comes out of this, not out of a guess.

  2. Us → DISCOM

    Extension application

    Filed against the existing consumer number with the revised load schedule and the reason for the increase. Existing agreement details go in with it.

  3. DISCOM

    Feasibility on the existing network

    Whether the current transformer, service cable and feeder can carry the higher load, or whether something upstream has to be uprated first.

  4. DISCOM → You

    Revised estimate & deposit

    Additional charges and additional security deposit against the higher load, plus the cost of any infrastructure the feasibility identified.

  5. Us

    Infrastructure work

    Transformer replacement or addition, cable or line upgrade, panel and protection changes — whatever the sanction requires, executed and tested.

  6. DISCOM

    Revised sanction & metering

    Supplementary agreement executed, meter or CT ratio changed where needed, and the revised sanctioned load reflected on the account.

Paperwork

What The File Has To Contain

Missing or inconsistent papers are the single commonest reason an application sits. We assemble the set before it is submitted.

  • Load extension application We prepare
  • Existing consumer number and recent bills You provide
  • Copy of the existing supply agreement You provide
  • Revised connected load schedule We prepare
  • Details of the new machinery being added You provide
  • Updated single line diagram We prepare
  • Ownership or lease proof if it has changed You provide
  • Test report for the added installation We prepare
Where It Stalls

Why Files Come Back

Applying for exactly what you need today

The next extension is a second full application and a second round of charges. The number worth applying for is the one that covers the expansion you can already see coming, weighed against the deposit and the fixed charge it carries.

Not noticing the LT ceiling until the estimate arrives

A modest-looking increase can push the connection over the ceiling and convert the whole file into an HT connection. Knowing that before you apply changes both the timeline and the budget.

Running on penal tariff while the file sits

Excess demand charges continue for every month the sanction is wrong. The cost of waiting is on the bill each cycle, which is what makes this the one liaisoning job worth starting immediately.

Transformer sized for the new load but nothing else touched

The cable, the panel, the protection settings and the earthing all sit downstream of the transformer. Uprating one and leaving the rest moves the weak point rather than removing it.
