DISCOM net metering application: the complete EPC guide

The DISCOM net metering application process is the set of steps that connect a rooftop solar plant to the grid and let it export surplus power, from portal registration through feasibility, sanction, inspection and a signed agreement. It is the compliance spine of every grid-tied rooftop job in India. The panels are the easy part — this application is what decides when a plant is actually commissioned and when your customer starts saving.

This guide is for the EPC founder-operator who runs these applications week after week across different DISCOMs. It defines net metering in plain words, walks the end-to-end process you actually run, gives you a documents checklist, explains feasibility and sanctioned load, sets honest expectations on approval time, and shows why applications stall. Read it once and the DISCOM step stops being the mysterious wait on every job.

What is net metering, in plain words?

Net metering is a billing arrangement where the surplus power your solar plant sends to the grid is set off against the power you draw from it, so you pay only for the net units. Think of the grid as a battery you share with the DISCOM. In the day, your rooftop makes more than the home uses, and the extra flows out — that is export. At night, the home draws from the grid — that is import. Net metering keeps score of both.

The device that keeps that score is a bidirectional meter. An old meter counts in one direction only. A bidirectional (net) meter counts both ways — units in and units out — on the same connection. At the end of the billing cycle, the DISCOM does the settlement: it subtracts your export from your import and bills the difference. Export more than you import and the surplus usually carries forward as banked units, per the state’s rules.

For the EPC, the practical meaning is simple. A plant is not truly “done” when the last panel is bolted down. It is done when the DISCOM has inspected it, fitted the bidirectional meter, and signed the connection agreement. Everything between the finished install and that signature is the net metering application — and running it cleanly is what stops jobs from sitting half-finished on your books.

The DISCOM net metering application, step by step

Every net metering application runs through the same eight steps, and each one has an owner and a date. The order rarely changes, even though the portal and the forms differ by DISCOM. Learn the flow once and you can run it in any state — you are just filling different boxes with the same information.

Notice the shape. The first three steps happen before installation — you apply, the DISCOM confirms the grid can take the export, and you get sanction to build. Skipping ahead and installing before sanction is a classic mistake: if feasibility comes back short, you have a plant you cannot fully connect. The last four steps are the metering and sign-off after the build, ending in the agreement that switches on net settlement.

Two of these steps often merge or swap depending on the state. Some DISCOMs inspect and fit the meter in one visit; others split them. Some issue feasibility and technical sanction as a single approval. The information you provide is the same either way, which is why treating the application as one connected government workflow — rather than a pile of separate forms — keeps every job moving.

What documents does a net metering application need?

Most DISCOMs ask for the same core set of documents, and a complete file on day one is the single biggest thing you control. Incomplete applications are the most common cause of a resubmission, and every resubmission resets the clock. Build the pack before you apply, not after a query lands.

The exact list is set by each DISCOM and changes from time to time, so the checklist above is a starting point, not gospel. One detail trips up more applications than any other: the name on the application must match the name on the electricity connection. If the property recently changed hands or the bill is in a relative’s name, sort that before you apply. For subsidised systems, keep the ALMM and DCR trail tight — the same records feed the subsidy claim later, as covered in our PM Surya Ghar guide for EPC contractors.

How do feasibility and sanctioned load work?

Feasibility is the DISCOM checking that the local grid can safely absorb the power your plant will export, and sanctioned load is the ceiling that check is measured against. This is the step that most affects system size, and getting it wrong quietly reshapes the whole quote.

Every connection has a sanctioned load — the maximum demand the DISCOM has approved for that premises. Many states cap the solar system size in relation to this sanctioned load, and to the capacity of the distribution transformer feeding the area. If your proposed system is larger than the connection can support, the DISCOM will either ask the customer to enhance their sanctioned load or trim the system size. Either way, it changes the design and the price.

The feasibility check also looks at the feeder and transformer — whether the local infrastructure can take more distributed export without hitting a limit. This is grid physics, not paperwork, and it is why two identical homes on different streets can get different answers. You cannot control the transformer, but you can size the system sensibly against the sanctioned load and flag any borderline case to the customer up front.

How long does net metering approval take?

Net metering approval commonly takes about 7 to 45 working days from a complete application to sanction — but it varies widely by state and DISCOM. Some states publish a service standard of a couple of weeks; in practice, feasibility, inspection scheduling and meter stock can stretch it. Never promise a customer a fixed date you do not control.

The honest framing to give a customer is a range with a caveat: “typically a few weeks once documents are complete, subject to the DISCOM.” The parts that eat time are rarely the form itself — they are the feasibility queue and the inspection slot, both of which sit with the DISCOM. What you can control is submitting a complete file, so the clock starts on day one and never resets on a missing document.

Why do net metering applications get rejected or delayed?

Most net metering delays come from a short list of avoidable problems, and nearly all of them are caught at the application stage. Knowing the list turns a rejection into a pre-flight check. Run through it before every submission.

The pattern is clear: the application does not fail because the process is hard. It fails because a step was missed — a document, a name, a size, a module list. Treat each of these as a checkbox on a standard pre-submission review and the rejection rate falls sharply. When you run dozens of applications a month, that discipline is the difference between a smooth pipeline and a desk full of queries.

Net metering vs gross metering vs net billing

Net metering, gross metering and net billing are three different ways a DISCOM can settle your solar export — and which one applies depends on the state and system size. The words get used loosely, so it helps to keep them straight before you promise a customer any saving.

For most residential rooftop systems, net metering is the model, and it is the one this guide covers end to end. But several states apply net billing or gross metering above a size threshold, and the thresholds change. The takeaway is simple: confirm which model applies for the specific state, DISCOM and system size before you quote the saving — because the model, not just the size, decides the customer’s return.

Does net metering vary by state?

Yes — net metering rules, size caps, settlement and the forms are set by each state regulator and DISCOM, so they genuinely differ across India. The eight-step application is broadly the same everywhere, but the limits and the fine print are not. This is why a process that works in one state can hit a wall in the next.

What varies: the maximum system size allowed under net metering, whether net billing kicks in above a threshold, how banked units are carried forward or settled at year end, the connection agreement format, and the DISCOM portal itself. What stays constant: you still register, clear feasibility, get sanction, install, apply for the meter, pass inspection and sign an agreement.

Because the numbers move, this guide deliberately keeps them general. For the current caps, settlement rules and forms in a specific state, use a dedicated state guide rather than a remembered figure. Our net-metering hub collects the state-by-state detail and is the right place to confirm the exact policy for the DISCOM handling your job — always check it before you quote or apply.

Tracking the net-meter application as a real stage

The fix for the “where is my net meter” question is to treat the application as real stages on the job — each with an owner and a follow-up date — not as paperwork done off to the side. When the DISCOM step lives on the same record as the build, it stops being the invisible thing that delays every project.

That is exactly how SuryaHub handles it. The net metering application is not a separate file; it is a set of tracked stages on the job — “applied,” “feasibility cleared,” “sanction received,” “net-meter applied,” “inspection booked,” “meter installed,” “agreement signed” — each with a date and a person responsible. Nothing waits silently in someone’s inbox, because a follow-up date makes the wait visible.

Sitting on the same record as the rest of the project, these government workflows mean an owner can see, at a glance, that job number twelve is stuck waiting on inspection and job number nine needs the agreement chased. That single view — every live job and the exact stage it is on — is the backbone of solar project management done properly, and it is where the DISCOM step finally stops being a black box.

Here is the honest part. SuryaHub is pre-revenue and building alongside two pilot EPCs, Suryantra Energy and RGESPL. We are not going to quote you an invented “X% faster approvals” number we cannot stand behind — the DISCOM sets the pace, not us. What the system does is make sure nothing waits because a person forgot: the application, inspection and agreement are tracked stages with follow-up dates, on the same record as the install. That is a real, shippable difference, and it is the one we will actually claim.

Frequently asked questions

What is the DISCOM net metering application process in India?

The DISCOM net metering application process is the set of steps that connect a rooftop solar plant to the grid and let it export surplus power. In order, it runs: register and apply on the DISCOM portal, get a feasibility check, receive technical sanction, install the system, apply for the net meter, pass a DISCOM inspection, get the bidirectional meter fitted, and sign the connection agreement. Only then is the plant commissioned.

What documents are required for a net metering application?

Most DISCOMs ask for the consumer electricity bill or connection number, proof of identity and ownership, a site or roof layout, the system rating in kW, and the datasheets for the modules and inverter. Subsidised jobs also need ALMM-listed module details and PM Surya Ghar registration. Exact documents vary by DISCOM, so always check the current checklist on the state portal before you apply.

How long does net metering approval take in India?

Net metering approval commonly takes about 7 to 45 working days, measured from a complete application to the sanction, though this varies widely by state and DISCOM. Feasibility, load sanction, inspection scheduling and meter stock all add time. Treat any timeline as targeted, not guaranteed, and always confirm the current service standard with the specific DISCOM handling the job.

What is a bidirectional meter in net metering?

A bidirectional meter is a single meter that records power flowing in both directions — the units you import from the grid and the surplus units your solar plant exports back. At the end of the billing cycle, the DISCOM nets the export against the import and bills only the difference. It replaces the old one-way meter and is fitted by the DISCOM during net-meter installation.

Why do net metering applications get rejected or delayed?

Net metering applications are most often delayed by incomplete documents, a system size above the sanctioned load, non-ALMM modules on a subsidised job, transformer or feeder capacity limits, or a mismatch between the applicant name and the electricity connection. Most of these are avoidable at the application stage. Check the DISCOM checklist and the sanctioned load before you apply, not after a rejection.

Is net metering the same in every state?

No. Net metering rules, system-size caps, the settlement method and even whether net metering or net billing applies are set by each state regulator and DISCOM, so they differ across India. The application steps are broadly similar, but the limits and forms are not. Always confirm the current policy for the specific state and DISCOM before you quote or apply, and use a state guide as your reference.
