PM Surya Ghar Sanctioned Load Mismatch, Fix in 2026

The single biggest reason PM Suryaghar applications stall in 2026 has nothing to do with documents, vendors, or panels, it is the sanctioned load mismatch. Households with a 2 kW sanctioned load on their electricity bill want a 3 kW system to claim the full ₹78,000 PM Suryaghar subsidy, but in states whose net-metering rules cap rooftop capacity at the sanctioned load, the DISCOM (Distribution Company) rejects the application: rooftop solar capacity in kilowatts (kW) cannot exceed the sanctioned load printed on your bill. Gujarat is an exception, because GERC allows residential rooftop solar irrespective of sanctioned load. Roughly one in six rejections we see trace back to this single line on the bill, and almost every one of them was preventable with a 15-day load enhancement filed in advance.

This guide walks through exactly how the sanctioned load constraint works under PM Suryaghar, how to read your own bill, how to file a load enhancement application with your DISCOM in 2026, what to do when your Distribution Transformer (DT) cannot handle the upgrade, and the named decision framework we use to advise residential customers.

Direct answer. Where your state’s rules cap rooftop solar at the sanctioned load on the bill, a 2 kW sanctioned home cannot install 3 kW and claim the ₹78,000 maximum subsidy without first filing a load enhancement application with the DISCOM (in Gujarat, GERC allows residential rooftop solar irrespective of sanctioned load, so this step is not needed). Enhancement typically takes 15 to 25 days, costs a modest DISCOM fee plus any extra security deposit, and requires DT capacity headroom. File the load enhancement first, then submit the Suryaghar application. Heaven Green Energy files both in parallel for our residential customers.

If you have already started the Suryaghar application and hit the “system size exceeds sanctioned load” error, do not abandon the application, withdraw it cleanly, file the load enhancement, and resubmit. The full path back is in §6 of this guide.

Why Sanctioned Load Matters for PM Suryaghar

Sanctioned load is the maximum power, measured in kilowatts (kW) or kilovolt-amperes (KVA), that your DISCOM has formally approved your service connection to draw. It is printed on every monthly electricity bill, usually next to “Sanctioned Load”, “स्वीकृत भार”, “मंजूर भार”, or “Contract Demand” depending on the state. For most residential consumers in India, sanctioned load sits between 1 kW and 5 kW; new flats often get only 2 kW even when the meter is capable of much more.

PM Suryaghar: Muft Bijli Yojana, administered by the Ministry of New and Renewable Energy (MNRE) through the pmsuryaghar.gov.in portal, does not itself set a sanctioned-load cap in its guidelines. The cap, where it exists, comes from state net-metering regulations: rooftop solar capacity ≤ sanctioned load. In those states the DISCOM checks the system size you apply for against your consumer record and flags or rejects a larger system at the application or feasibility stage. Gujarat’s GERC, by contrast, allows residential rooftop systems irrespective of sanctioned load.

The financial impact of staying capped at your existing sanctioned load is severe. The MNRE subsidy schedule is tiered, ₹30,000 for 1 kW, ₹60,000 for 2 kW, and ₹78,000 for 3 kW or more. A household with a 2 kW sanctioned load that installs 2 kW gets ₹60,000 and leaves ₹18,000 on the table until it adds the third kW. Across the next 25 years, the same enhancement also adds an extra ~1,650 kWh per year of generation worth ₹11,500 annually at typical tariffs, which compounds to over ₹2.8 lakh of lifetime savings before degradation adjustment.

This is why we treat sanctioned load as a Stage 0 check, before bills, before Aadhaar, before vendor selection. If your sanctioned load is below your target system size, the entire timeline shifts: load enhancement runs as a 15 to 25 day pre-step, the Suryaghar application follows, and the total project clock moves from 60 days to 75 to 85 days. That is still inside any reasonable installation window, but only if you start the enhancement on day one.

The DISCOM side of this is straightforward, the local distribution network is engineered for the cumulative sanctioned load on each feeder. Rooftop solar exports power back through the same wires, and if the system size exceeds what the network was designed to handle, voltage rises beyond safe limits and other consumers on the same feeder suffer. The sanctioned load rule is a proxy for “this address is engineered to handle this much current in either direction”.

Read your bill carefully. The figure you want is usually labelled “Sanctioned Load” in kW. Some DISCOMs print it in KVA (kilovolt-amperes), in which case you can use a 0.9 power factor conversion, 3 KVA approximately equals 2.7 kW. Other bills show “Connected Load” instead; for PM Suryaghar, the figure that matters is sanctioned, not connected. If in doubt, call the DISCOM consumer helpline with your consumer number ready.

The 3-Decision Sanctioned Load Strategy

When a residential customer comes to Heaven Green with a sanctioned load lower than their target solar capacity, we run them through what we call The 3-Decision Sanctioned Load Strategy. It is a sequenced framework, each decision feeds into the next, and skipping a step almost always creates rework. The framework replaces what is usually a panicked back-and-forth with the DISCOM with three clean yes/no questions.

Decision 1, Enhance the Load or Cap the Solar System

This is the financial decision. You have two paths: file a load enhancement and access the full 3 kW / ₹78,000 subsidy band, or stay at your current sanctioned load and build a smaller system. The right answer depends on your monthly bill, your roof area, and your appetite for a 15 to 25 day pre-step before the Suryaghar timeline begins.

Cap the system at current load when your monthly consumption stays consistently below 250 kWh per month, your roof has limited space for more than 2 kW anyway, or you are uncomfortable adding a delay to the project. The downside is real but bounded, a 2 kW system in most Indian cities still generates 240 to 280 kWh per month and saves ₹1,700–₹2,000 per month at upper-slab tariffs.

Enhance the load when your monthly consumption is consistently above 300 kWh, when your bill regularly hits the top slabs, when you have at least 30 m² of unshaded roof, or when you plan to add air conditioning or an electric vehicle in the next 3 years. The ₹18,000 extra subsidy (₹60,000 → ₹78,000) alone pays for the enhancement fee many times over.

Decision 2, Phase the Installation or Go All-at-Once

This is the timing decision. If you have decided to enhance the load (Decision 1 = Yes), you still have a choice on sequencing. The all-at-once path runs enhancement and Suryaghar as a single project, file the enhancement, wait for the revised bill, then submit Suryaghar with the new sanctioned load. This is the cleanest path and what we recommend for most customers.

The phased path installs solar at your current sanctioned load now (e.g. 2 kW), claims the ₹60,000 subsidy, and adds an additional 1 kW after a separate enhancement and a fresh net metering application in year two or three. We use this path only for customers who are blocked by DT loading (see Decision 3) or who need to defer the upfront cost. The downside of phasing is real: you pay vendor mobilisation and net meter charges twice. The subsidy is not lost, though, because the guidelines allow additional subsidy for the balance capacity up to 3 kW overall (₹18,000 for the third kW).

Decision 3, Confirm the DT Has Capacity for the Upgrade

This is the engineering decision and the most-skipped one. Your local Distribution Transformer (DT), the pole-mounted or pad-mounted unit that steps voltage down for your street, has a finite KVA rating, typically 25 KVA, 63 KVA, 100 KVA, or 250 KVA depending on locality. Every consumer on that DT contributes to its loading. If your DT is already above 90% utilisation, the DISCOM will either deny your load enhancement, approve it conditionally with export restrictions, or require a DT upgrade at your cost before the enhancement goes through.

Before filing the enhancement, ask the DISCOM sub-divisional engineer for the current DT loading; DISCOMs track this internally and will often share it on request. If your DT is over 90% loaded, jump to §5 of this guide for the recovery path.

How to Check Your Current Sanctioned Load

Before anything else, you need to know your current sanctioned load with certainty. There are four reliable ways to verify it in 2026, and we recommend using at least two of them to cross-check.

The simplest is the printed bill itself. Pull your most recent monthly bill, physical or PDF download, and locate the row labelled “Sanctioned Load”, “Sanc. Load”, “Connected Load”, “Contract Demand”, or the Hindi/regional equivalent. The figure will be in kW or KVA. For PM Suryaghar, kW is the comparison unit; if your bill shows KVA, multiply by 0.9 to approximate kW (since most residential power factors hover near 0.9). A 3 KVA sanctioned connection equals roughly 2.7 kW.

The second method is the DISCOM consumer portal. Every major DISCOM in India now has a self-service portal where, after logging in with your consumer number, you can view your service order, the formal document that records sanctioned load, tariff category, phase (single or three-phase), and connection date. For MSEDCL consumers in Maharashtra and most other DISCOMs, look in the account or connection details after you log in; many DISCOMs also print it on every bill PDF.

The third method is calling the DISCOM helpline. Have your consumer number ready, ask explicitly for “current sanctioned load in kilowatts”, and request the answer in writing via SMS or email. Helplines are accurate but slow, expect a 20-minute call in many cases.

The fourth method is the pmsuryaghar.gov.in portal itself. When you enter your consumer number during Suryaghar registration, the portal fetches your connection details from the DISCOM, which can help you confirm the figure your DISCOM holds before you choose a system size.

The actions below apply where your state caps rooftop solar at sanctioned load. In Gujarat, residential rooftop solar is allowed irrespective of sanctioned load, so you can size to your consumption instead.

Once you have a verified sanctioned load figure, compare it to the system size you want. If sanctioned load is greater than or equal to the system size, you can skip straight to the Suryaghar application, see our PM Suryaghar complete guide for the full process. If sanctioned load is less than the system size, continue to the next section.

Filing a Load Enhancement Application

A load enhancement application is a standalone request to your DISCOM to formally increase your sanctioned load. It runs entirely outside the PM Suryaghar portal, you file with the DISCOM directly, they survey and approve, and then your revised sanctioned load reflects on the next monthly bill. Only after that revised bill is generated can you submit the Suryaghar application at the new system size.

The application can be filed online for most DISCOMs in 2026. The MSEDCL “MahaVitaran” app and web portal accept enhancement requests end-to-end; you upload the latest bill, Aadhaar, ownership proof, and submit a digital signature. Tata Power Mumbai and Adani Electricity Mumbai both support fully digital enhancements. BESCOM in Karnataka allows enhancement during the Suryaghar application itself as a combined request, a useful shortcut we exploit for our Bengaluru customers.

For DISCOMs that have not yet digitised, the application is filed in person at the sub-divisional office. Carry the same document set, get the receipt stamped, and follow up after seven working days for the DT capacity check confirmation. In Gujarat (MGVCL, UGVCL, DGVCL, PGVCL and Torrent Power), you do not need a load enhancement for residential rooftop solar, because GERC allows it irrespective of sanctioned load.

The standard document set for enhancement is short: latest paid bill, Aadhaar (front and back), ownership proof (property tax receipt or sale deed), and the filled enhancement form. Most DISCOMs also ask for a brief reason, “installation of rooftop solar under PM Suryaghar” is a fully acceptable reason and accelerates approval in DISCOMs with a renewable energy desk.

Fees vary by state and the kW jump requested. There is usually a small application or processing fee, plus any change in security deposit; some DISCOMs work the deposit out per kW and others from your average bill. The deposit is refundable on disconnection but appears as an upfront charge on the revised bill. Each DISCOM publishes these in its schedule of charges approved by the state regulator, so ask for the current figures before you file rather than relying on a national average.

The enhancement workflow itself has four stages: application submission, document verification (1 to 3 days), site visit and DT loading check by the DISCOM section officer (5 to 10 days), and final approval with revised sanctioned load reflected on the next bill cycle (which can take up to one full billing month). The site visit is the swing factor, DISCOM staff sometimes need to physically check the meter and the local DT loading before approving.

Want both filed in parallel? Heaven Green files your load enhancement on day one and prepares your PM Suryaghar application on day three so the Suryaghar submission goes in the moment your enhanced bill is ready. Net delay compared to a no-enhancement application: 12 days. Talk to our team →

Once the enhancement is approved, wait for the next bill to be generated showing the new sanctioned load, this is the trigger document for the Suryaghar portal. Without the updated figure in the DISCOM database, the portal still shows the old sanctioned load and you cannot apply for the larger system. Our Suryaghar document checklist PDF covers what to gather for the parallel Suryaghar application.

What If Your DT Cannot Handle the Load Upgrade

Roughly 12% of load enhancement applications we handle run into a DT capacity constraint, the local Distribution Transformer is loaded above 90% of its rated KVA, and the DISCOM cannot approve a fresh load addition without engineering action. This is more common in dense urban localities (older parts of Pune, central Bengaluru, west Delhi) and in colonies built before the latest network upgrade cycle. The DT capacity check is a hard engineering constraint, not a policy preference, so a “no” here cannot be argued, it has to be solved.

There are three possible outcomes when the DT capacity check returns a red flag. Outcome 1 is conditional approval with export restriction: the DISCOM allows the enhancement but requires your inverter to be programmed with a zero-export or limited-export setting, which means surplus solar units cannot be sold back to the grid. Outcome 2 is denial pending DT upgrade: the DISCOM refuses the enhancement until the local DT is upgraded to a higher KVA rating. Outcome 3 is denial pending feeder rebalancing: the DISCOM moves your connection to a different DT with spare capacity, usually within the same neighbourhood, before approving.

The loading bands below are indicative; each DISCOM applies its own planning criteria.

When you hit Outcome 1 (conditional approval), the financial impact can be smaller than it sounds if you use most of your generation during the day, with washing machines, refrigerators, fans, water pumps, and AC running during peak sun hours. The ₹78,000 subsidy still applies, the rooftop array still generates at full capacity, and only the export credit is forfeited.

Outcome 2 is more disruptive. A DT upgrade is a 4 to 8 week DISCOM capital project, the network planning cell schedules the replacement, procures the higher-KVA unit, and coordinates the swap on a planned outage day. In some states the consumer is asked to contribute part of the cost; in others the DISCOM funds it, for example through network works under the Revamped Distribution Sector Scheme. Ask explicitly whether an upgrade for your area is already planned under RDSS or the DISCOM’s own capital programme; if so, it may come at no cost to you.

Outcome 3 is the cleanest fix when available. The DISCOM moves your service from the overloaded DT to a nearby one with headroom. This usually takes 2 to 3 weeks and a single planned outage. Your meter, billing relationship, and consumer number all stay the same, only the upstream connection point changes.

For customers whose DT cannot be upgraded in their target timeline, our recommendation is to install at the current sanctioned load now, lock in the ₹60,000 subsidy for the 2 kW band, and queue the enhancement and the additional 1 kW as a phase-two project the moment the DT is rebuilt; the scheme allows extra subsidy for the balance capacity up to 3 kW overall, so that third kW can still earn ₹18,000. This is the phased-approach path from Decision 2 of the framework. Detailed sizing guidance for sub-3 kW homes is in our home solar system size guide.

If the DT issue blocks the project and you suspect the DISCOM has miscategorised your loading, ask in writing for the loading data behind its decision, and escalate to the DISCOM’s Consumer Grievance Redressal Forum if the answer does not hold up. Keep all DISCOM correspondence in writing.

Common Mistakes That Stall the Enhancement

Six recurring mistakes account for most of the delays we see in load enhancement applications across states. Each one is preventable with a 5-minute pre-check.

1. 1
   Filing the Suryaghar application before the enhancement is approved. In states that cap rooftop solar at sanctioned load, the DISCOM flags or rejects the application. File enhancement first, wait for the revised bill, then submit Suryaghar.
2. 2
   Reading KVA as kW. A 3 KVA sanctioned load is approximately 2.7 kW at 0.9 power factor, not 3 kW. Confirm units before assuming you have headroom.
3. 3
   Asking for a kW jump that triggers a phase change. Moving from 5 kW to 7 kW often forces a single-phase to three-phase upgrade, adding ₹8,000–₹15,000 in meter and wiring costs.
4. 4
   Skipping the DT capacity question. Submitting an enhancement without first checking DT loading wastes 15 days if it comes back as a denial. Ask the section officer first.
5. 5
   Missing the bill cycle. Even after approval, the new sanctioned load only appears on the next billing cycle's bill. Submitting Suryaghar before that bill prints results in a portal rejection.
6. 6
   Name mismatch between bill and Aadhaar at enhancement time. DISCOM enhancement uses the same identity check as Suryaghar. Fix any mismatch first, see our rejection reasons guide.

A seventh, subtler mistake: customers who self-file the enhancement and then run into a portal error during the Suryaghar submission often don’t realise the two systems are not synced in real time. Even with an approved enhancement and a revised bill, the portal may still show the old sanctioned load for a while. If you hit this, raise a query on the portal with your revised bill attached, see our PM Suryaghar portal error fix guide for the exact escalation path.

Decision: Enhance Load or Cap Solar at Current Capacity

For most residential customers facing the sanctioned load mismatch, this is the decision the entire project pivots on. Below is the side-by-side trade-off, framed against the specific 2 kW vs 3 kW case which is the most common scenario we see.

The economics make the enhancement worthwhile in almost every scenario where the household consumes above 250 kWh per month and has roof space for a 3 kW array (about 18 to 20 m² unshaded). The ₹18,000 extra subsidy alone is many times the enhancement fee, and the additional 1 kW of generation is worth roughly ₹11,500 per year at upper-slab tariffs. Over a 25-year system life, that adds up to about ₹2.8 lakh in undiscounted savings.

Verdict. For most residential customers facing a sanctioned load mismatch, file the load enhancement first and then submit the PM Suryaghar application at the higher capacity. The 15 to 25 day pre-step is a small price for the ₹18,000 subsidy uplift and the long-term generation gain. Cap the system at current load only when the DT cannot be upgraded, when consumption stays under 250 kWh per month, or when roof area limits the system to 2 kW anyway. The full 3 kW PM Suryaghar route remains the best subsidy-to-effort ratio in the scheme.

For a calculator that runs your specific numbers, bill amount, roof area, sanctioned load, expected savings, use the Heaven Green solar calculator. It outputs the enhance-vs-cap decision recommendation alongside the cost and payback figures.

How Heaven Green Energy Helps with Load Enhancement

Heaven Green Energy is MNRE-empanelled and has handled hundreds of PM Suryaghar applications where the sanctioned load required an upfront enhancement. We treat the enhancement as part of the Suryaghar workflow, not a separate consumer task you have to chase the DISCOM for.

Our load enhancement service runs in five steps. First, we audit your latest bill within 24 hours of you signing up, verifying sanctioned load (in kW, after KVA conversion if needed), tariff category, phase, and bill name consistency with Aadhaar. Second, we file the enhancement application with the relevant DISCOM the same day, online where supported and in person where required. Third, we accompany the DISCOM section officer for the site visit and DT loading check, which usually happens within 5 to 10 days of the application. Fourth, we monitor the DISCOM internal queue daily and escalate any delay through the renewable energy desk. Fifth, the moment the revised bill is generated with the new sanctioned load, we submit the PM Suryaghar application at the higher capacity.

The net result is a parallel-tracked project that compresses what could be a 45-day sequence into a 75-day end-to-end timeline, only 12 days longer than a no-enhancement Suryaghar project. We’ve delivered this on hundreds of installations across our service territories, and the success rate on enhancements (excluding DT-capacity hard blocks) is above 96%.

Frequently Asked Questions

Can I install a 3 kW solar system under PM Suryaghar if my sanctioned load is only 2 kW?

It depends on your state. Where state net-metering rules cap solar capacity at the sanctioned load on the bill, a 2 kW sanctioned load limits you to a 2 kW system, which caps your central subsidy at ₹60,000 instead of the full ₹78,000. In Gujarat, GERC allows residential rooftop solar irrespective of sanctioned load, so you can install 3 kW without an enhancement. In capping states, to install 3 kW and claim the maximum subsidy, you must first file a load enhancement application with your DISCOM, wait 15 to 25 days for approval, and then submit the Suryaghar application against the revised sanctioned load printed on your updated bill.

How long does a load enhancement application take in 2026?

We plan for 15 to 25 days from submission to revised bill generation, though it varies by DISCOM and subdivision; online filing (offered by MSEDCL and the Mumbai licensees, among others) is usually quicker than an office visit. The DT capacity check by the section officer is typically the longest single step. In Gujarat, a load enhancement is not needed for residential rooftop solar.

What does a load enhancement application cost?

Costs are usually modest but vary by DISCOM: a small application or processing fee plus any additional security deposit, which some DISCOMs calculate per kW and others from your average bill. Ask for your DISCOM’s current schedule of charges before filing. The deposit is refunded if you ever disconnect the service. In Gujarat you do not need an enhancement for rooftop solar at all.

What is a Distribution Transformer (DT) and why does its capacity matter for solar?

A Distribution Transformer is the pole-mounted or pad-mounted electrical unit that steps high-voltage feeder current down to the 230 V single-phase or 415 V three-phase supply that reaches your home. Every consumer on a DT contributes to its loading. When you install rooftop solar, the system can push surplus power back through the DT, and if the DT is already heavily loaded, the additional capacity creates voltage rise and safety issues for other consumers on the same feeder. DISCOMs check DT loading before approving any load enhancement; loading above 90% can trigger conditional approval, export restriction, or outright denial pending a DT upgrade.

Can I file the load enhancement and PM Suryaghar application at the same time?

Karnataka BESCOM has offered a combined enhancement-and-Suryaghar request; check whether it is still available. In other capping states the two applications are sequential, DISCOM enhancement must be approved and reflected on a revised bill before the Suryaghar portal will accept the higher system size. Practically, Heaven Green files the enhancement on day one and prepares the Suryaghar application documents in parallel so submission happens the same day the revised bill is issued. Total parallel-tracked timeline: 75 days from sign-up to subsidy disbursement.

What happens if my DT does not have capacity for the load upgrade?

The DISCOM has three possible responses. First, conditional approval, they grant the enhancement but require your inverter to be programmed with a zero-export or limited-export setting, so surplus solar units stay onsite rather than feeding the grid. Second, denial pending DT upgrade, the DISCOM schedules a transformer replacement, typically 4 to 8 weeks, possibly with a partial consumer cost contribution in some states. Third, feeder rebalancing, they move your service to an adjacent DT with spare capacity, usually within 2 to 3 weeks and one planned outage. None of these eliminate the project; they only adjust the path and timeline.

Is sanctioned load the same as connected load on my electricity bill?

No, they are different. Sanctioned load is the formally approved maximum capacity the DISCOM has authorised your service for. Connected load is the sum of the wattage of all appliances you have wired in, which can be higher or lower than sanctioned. Where a state caps rooftop solar by load, it is the sanctioned load that counts. If your bill only shows connected load, call the DISCOM helpline and request the sanctioned figure in writing; you cannot use connected load as a substitute on the Suryaghar portal.

What if my bill shows sanctioned load in KVA instead of kW?

Convert using a 0.9 power factor as an approximation, 1 KVA equals roughly 0.9 kW for residential connections. So 3 KVA sanctioned load is approximately 2.7 kW, which is below the 3 kW threshold for the maximum ₹78,000 subsidy. To install a 3 kW system you would need to enhance to at least 3.4 KVA, which rounds up to 3.5 KVA in DISCOM tariff slabs. Check which unit your own bill uses before you compare it with the system size.

Will my electricity bill increase after the load enhancement even before installing solar?

Possibly, slightly. Many DISCOMs link the monthly fixed charge to your load, and the amounts vary widely by state. In Gujarat’s state DISCOMs, for example, the residential fixed charge is ₹15 a month up to 2 kW and ₹25 a month above 2 kW up to 4 kW (GERC schedule from 1 April 2026), so the step from 2 kW to 3 kW adds ₹10 a month. Once the rooftop system is commissioned, the savings from solar generation far outweigh a higher fixed charge, but check your own DISCOM’s schedule and budget for the bump during the gap between enhancement approval and solar commissioning.

Can I reverse the load enhancement if I change my mind about solar later?

Yes, but it requires another DISCOM application, a load reduction request. Reduction is faster and cheaper than enhancement (typically 7 to 15 days, smaller fees) because no DT capacity check is needed. The security deposit paid for the additional kW is refunded on reduction. That said, almost no customer reduces sanctioned load after enhancement, the extra capacity is useful for future appliances and AC additions even if the solar plan changes.
