Before your customer signs the work order, they will ask one question you need to answer with precision: "What charges will the DISCOM levy for net metering?" Get this wrong and you either over-promise a payback period or lose the sale to a competitor who quoted confidently. This guide gives you the actual state-by-state numbers for net metering charges across India in 2026, application fees, security deposits, meter costs, export tariff rates, banking charges, and wheeling charges, so your sales and operations teams are quoting from fact, not assumption.
KEY TAKEAWAY
Net metering charges vary significantly by state and DISCOM. Gujarat DISCOMs currently offer the most consumer-friendly structure, zero application fee and a fixed bidirectional meter charge of ₹3,000–₹4,500. States like Tamil Nadu and Maharashtra charge higher upfront fees but compensate with higher export tariff rates or retail-tariff-linked credits. Karnataka (BESCOM) offers one of the best export tariff structures at ₹3.56–₹4.16/unit under KERC FY 2026 orders. Understanding these differences before you quote allows you to accurately project the net metering payback period for your customer's specific state.
Why net metering charges matter to an EPC business
Net metering is not free. Every DISCOM levies some combination of one-time charges (application, meter, security deposit) and recurring charges (wheeling, banking, service charges on export). When you are scaling across multiple states, Gujarat, Maharashtra, Karnataka, Delhi, you cannot apply a single cost template. A miscalculated charge structure produces a wrong payback period in your proposal, which either kills the sale or creates a credibility problem when the first bill arrives.
For a scaling EPC owner managing projects across states, the practical implication is: your quotation tool must be state-aware on net metering charges. If you are still building proposals manually or using a generic Excel sheet, DISCOM approval timelines and charge structures will create proposal errors at volume.
Net metering vs gross metering, charges differ
Before the state-by-state breakdown, understand the charging architecture difference between net metering and gross metering. Under net metering, the consumer pays only for net consumption (import minus export in the billing period). Under gross metering, all generation is exported at a fixed feed-in tariff, and all consumption is imported at the retail tariff, two separate meters, two separate transactions.
| Parameter | Net Metering | Gross Metering |
|---|---|---|
| Export credit mechanism | Offset against import bill (unit credit) | Cash payment at fixed feed-in tariff |
| Meter type required | Single bidirectional meter | Two meters (import + export) |
| Typical meter cost to consumer | ₹3,000–₹6,000 (varies by state) | ₹4,000–₹8,000 (two meters) |
| Who typically uses it | Residential, small commercial (majority of states) | Large C&I in some states, Tamil Nadu for certain categories |
| Banking of surplus units | Allowed (monthly or annual, state-dependent) | Not applicable, settled as cash each month |
| Better for whom | Residential consumers with significant self-consumption | Large generators where feed-in tariff > retail rate |
EPC note. Most residential PM Surya Ghar applications in India go through net metering, not gross metering. The central scheme mandates net metering for all residential beneficiaries. If your state DISCOM insists on gross metering for residential, that is a compliance matter worth escalating to MNRE via the national portal.

Important. Meter charges listed above are approximate and can vary by the specific DISCOM sub-division and meter model procured. Always request the current charge schedule from the local DISCOM office or download the latest tariff order from the respective State Electricity Regulatory Commission (SERC) website before finalising a customer proposal.
Solar export tariff rates by state, the most important number
The export tariff, what the DISCOM credits per unit of solar electricity you export, is the single biggest variable in the payback period calculation. A difference of ₹1/unit in the export tariff can shift residential payback by 12–18 months. Study this table carefully before quoting.
| State / DISCOM | Export Tariff Structure | Effective Rate (FY 2026) | Banking Period | Surplus Settlement |
|---|---|---|---|---|
| Gujarat (all 4 DISCOMs) | Net billing, export unit credited at applicable retail tariff slab (2 paisa lower than import) | ~₹3.25–₹4.85/unit (slab-dependent) | Monthly, surplus carries forward for 12 months | Annual cash settlement at ₹2.25/unit (GERC order) for any remaining surplus |
| Maharashtra, MSEDCL | Net billing, export offset against import at prevailing residential LT slab rate | ₹4.50–₹6.00/unit (varies by consumption slab) | Monthly carryover; annual cash settlement | Annual cash at ₹3.50/unit (MERC order) for surplus |
| Karnataka, BESCOM | Fixed feed-in / net metering credit rate set by KERC; not linked to retail slab | ₹3.56/unit (≤10 kW) | ₹4.16/unit (10 kW–500 kW) | Monthly carryover; annual settlement at end of financial year | Surplus settlement at KERC-determined rate; not forfeited |
| Tamil Nadu, TANGEDCO | Gross metering for commercial; net metering for residential with fixed credit rate | ₹3.00/unit (residential NM credit rate, TNERC 2024) | Monthly billing offset; surplus carried to next month | Annual surplus at ₹2.50/unit cash payment |
| Delhi, BSES Rajdhani / Yamuna / TPDDL | Net metering, export credited at DERC-determined average pooled cost (APC) rate | ₹5.00–₹6.50/unit (APC rate; one of highest in India) | Monthly billing; annual settlement for surplus | Annual cash settlement at APC rate; very favourable |
| Rajasthan, JVVNL | Net billing at prevailing LT residential slab rate (similar to Gujarat model) | ₹3.50–₹5.00/unit (slab-dependent) | Monthly carryover; annual settlement | Surplus settled at RERC-approved lower rate annually |
| Uttar Pradesh, PVVNL | Net billing, export offset at UPERC-determined rate; typically retail-rate linked | ₹3.00–₹4.50/unit (slab-dependent, UPERC 2025) | Monthly carryover; annual settlement | Annual surplus at lower settlement rate; confirm with UPERC order |
| Andhra Pradesh, APEPDCL | Net billing at APERC-approved rate; residential systems under 10 kW get credit at retail rate | ₹3.25–₹4.50/unit (APERC tariff 2025) | Quarterly carryover; annual settlement | Annual surplus at APERC minimum rate |
| Telangana, TSSPDCL | Net billing at TSERC-determined rate; residential category gets credit at import slab rate | ₹2.75–₹4.00/unit (TSERC tariff 2025) | Monthly carryover; annual settlement | Annual surplus at lower settlement rate; confirm with TSERC order |
Delhi advantage. Delhi's net metering export credit, linked to the average pooled cost of power purchase, is consistently among the highest in India at ₹5–₹6.50/unit. For a residential customer in Delhi with a 5 kW system exporting 300 units/month, this translates to ₹1,500–₹1,950/month in net bill reduction compared to ₹975–₹1,455 in Gujarat. Factor this into your payback period presentation when pitching Delhi customers.
Wheeling charges and banking charges for export, the hidden cost
Many EPCs quote only the export tariff without flagging wheeling and banking charges that some states levy on the exported units. These reduce the effective return from net metering.
| State | Wheeling Charge on Export | Banking Charges | Cross-Subsidy Surcharge | Net Impact |
|---|---|---|---|---|
| Gujarat (all DISCOMs) | Nil for residential (≤10 kW) | Nil for LT/residential NM | Nil for residential NM | Most favourable, no hidden deductions |
| Maharashtra (MSEDCL) | Nil for residential LT (≤10 kW) | Nil for LT category | Nil for residential NM | Favourable for residential; C&I applies wheeling |
| Karnataka (BESCOM) | Nil for systems ≤500 kW (KERC waiver) | Nil for NM, KERC order waives banking charges under NM | Not applicable under NM framework | Clean export credit with no wheeling deduction for most systems |
| Tamil Nadu (TANGEDCO) | Wheeling charge applies for C&I gross metering; nil for residential NM | Banking charge of 2% of energy for systems above 5 kW under certain orders | CSS applicable for commercial open access; nil for small NM | Moderate, verify category before quoting |
| Delhi (all DISCOMs) | Nil for residential (DERC exemption) | Nil under NM regulations | Nil for residential NM | Excellent, high export rate + no deductions |
| Rajasthan (JVVNL) | Wheeling charge waived for systems ≤10 kW | Nil for residential NM | CSS applicable above 10 kW for commercial | Good for residential, verify for commercial/industrial |
| UP (PVVNL), AP, Telangana | State-specific; UP has wheeling charge for HT consumers; nil for LT | Some banking charges apply to annual surplus in certain categories | CSS may apply, check UPERC/APERC/TSERC latest orders | Verify current SERC tariff order before quoting |
Gujarat DISCOM comparison, DGVCL vs MGVCL vs PGVCL vs UGVCL
Gujarat is frequently the most active state for residential solar installations. All four Gujarat DISCOMs operate under the same GERC regulations but have minor operational differences in processing speed and portal experience.
| DISCOM | Area Served | Typical NM Timeline | Portal | Guide |
|---|---|---|---|---|
| DGVCL | South Gujarat, Surat, Bharuch, Navsari, Valsad, Tapi, Dang, Narmada | 30–45 days (urban); up to 55 days (rural) | consumer.dgvcl.com | DGVCL NM guide |
| MGVCL | Central Gujarat, Vadodara, Anand, Kheda, Panchmahals, Dahod | 35–55 days | mgvcl.com consumer portal | See what is net metering |
| PGVCL | Paschim (West) Gujarat, Rajkot, Junagadh, Porbandar, Jamnagar, Amreli | 30–50 days | pgvcl.com consumer portal | See what is net metering |
| UGVCL | North Gujarat, Mehsana, Patan, Gandhinagar, Sabarkantha, Banaskantha | 30–50 days | ugvcl.com consumer portal | UGVCL NM guide |
Gujarat EPC advantage. Because all four Gujarat DISCOMs operate under identical GERC regulations and charge structures, a Gujarat-focused EPC can build a single proposal template for net metering charges and simply switch the DISCOM name and portal URL. This reduces proposal preparation time significantly compared to multi-state operations where every state requires a different charge structure input.
System capacity limits for net metering by state
Not all states allow unlimited capacity under net metering. Knowing the cap upfront avoids a situation where your customer's proposed system size exceeds the net metering limit and requires a different regulatory pathway.
-
1
Gujarat (all DISCOMs): Net metering available up to system capacity equal to the consumer's sanctioned load or 1 MW (whichever is lower). Systems above 1 MW use a separate gross metering / open access route. Most residential systems are 1–10 kW and fall comfortably within limits.
-
2
Maharashtra (MSEDCL): Net metering available up to 500 kWp for LT consumers. Above 500 kWp requires a separate power purchase agreement. Residential cap: sanctioned load equivalent. Commercial cap: 500 kWp per MERC regulations.
-
3
Karnataka (BESCOM): Net metering available up to 10 MW (10,000 kW) under KERC regulations, one of the most generous limits in India. Residential sub-limit: equal to sanctioned load. This makes BESCOM territory attractive for large commercial and industrial rooftop projects.
-
4
Tamil Nadu (TANGEDCO): Net metering capped at system capacity = sanctioned load or 1 MW, whichever is lower. Commercial consumers above a threshold must use gross metering (TNERC regulations). Confirm consumer's tariff category with TANGEDCO before advising net vs gross metering.
-
5
Delhi (BSES / TPDDL): Net metering for residential up to 500 kW per connection point. For larger systems, group net metering or open access is used. DERC's regulations are well-defined and the DISCOM processing is relatively structured compared to many other states.
-
6
Rajasthan (JVVNL) and UP (PVVNL): Net metering typically capped at 1 MW. Rajasthan has a strong solar resource and JVVNL processing has improved significantly since 2023. UP's PVVNL jurisdiction covers western UP; confirm the correct DISCOM for your project location (PVVNL, MVVNL, PuVVNL, or KESCO).
Pros and cons of net metering for EPCs operating across multiple states
ADVANTAGES FOR EPC BUSINESS
- Net metering is the dominant model, one process to master across most states
- Residential systems (1–10 kW) typically face zero wheeling/banking charges, clean credit
- Central MNRE mandate for net metering under PM Surya Ghar removes ambiguity for scheme projects
- Bidirectional meter cost is a one-time charge, not a recurring burden on customer economics
- High export tariff states (Delhi, Maharashtra) enable faster payback, stronger sales pitch
- Regulatory framework is mature in Gujarat, Karnataka, Delhi, fewer DISCOM disputes
CHALLENGES FOR EPC BUSINESS
- Charges differ per state, manual proposal building leads to quoting errors at scale
- Tariff orders update annually, last year's rates may already be outdated
- Some states (Tamil Nadu, UP) have procedural complexity that slows approval
- Security deposit and meter cost recovery needs to be built into customer pricing
- Annual surplus settlement rates are often lower than in-period credits, affects payback accuracy
- C&I projects face wheeling and CSS charges in most states, reduces IRR on large installations
How QuickEstimate handles multi-state net metering charges in proposals
For a scaling EPC running projects across Gujarat, Maharashtra, and Karnataka, manually tracking state-wise net metering charges, export tariffs, and banking rules is a proposal-quality risk. Here is how QuickEstimate's proposal module addresses this:
- → State-aware payback calculation: Select the customer's state and DISCOM, and the export tariff, banking structure, and applicable charges are automatically loaded into the payback model, no manual lookup required.
- → Meter cost line item: One-time meter charge for the relevant DISCOM appears as a separate line in the cost breakdown, visible to the customer and accounted for in total project cost.
- → PM Surya Ghar integration: For empanelled PM Surya Ghar vendors, QuickEstimate flags when a system qualifies for the scheme and auto-adjusts the subsidy, net metering tariff, and payback period in a single click.
- → DISCOM approval tracker: Track the net metering application stage for every project across all active DISCOM zones. See which applications are at inspection stage, which are pending meter installation, and follow up from a single dashboard, relevant when managing DISCOM approval processes across multiple states.
- → Team visibility on pending commissionings: Your operations team sees every project awaiting net meter installation in a filtered view, so the post-installation follow-up doesn't fall through the cracks while your sales team is closing new leads.
Key regulatory sources for net metering charges in India
For official reference, here are the regulatory bodies and portals to verify current net metering charge orders for each state:
Always verify before quoting. The figures in this guide reflect publicly available tariff orders and DISCOM schedules as of mid-2026. Tariff orders are updated annually (usually April for most states). Before including any charge figure in a customer proposal, verify against the latest SERC tariff order or the DISCOM's official charge schedule:
- Gujarat: gercin.org (GERC official site, download latest tariff order)
- Maharashtra: mercindia.org.in (MERC, Maharashtra Electricity Regulatory Commission)
- Karnataka: kerc.karnataka.gov.in (KERC, Karnataka Electricity Regulatory Commission)

- Delhi: derc.gov.in (DERC, Delhi Electricity Regulatory Commission)
- National solar portal for PM Surya Ghar: pmsuryaghar.gov.in
Summary: which state is most favourable for net metering economics?
For a residential customer evaluating solar ROI, and for an EPC owner advising on payback projections, here is the practical summary:
Best export tariff: Delhi (₹5–₹6.50/unit APC-linked), highest net metering credit in India for residential consumers.
Best overall charge structure: Gujarat DISCOMs, zero application fee, low meter cost (₹3,000–₹4,500), zero wheeling/banking charges for residential. Simple, predictable, and well-regulated under GERC.
Best capacity limit for C&I: Karnataka (BESCOM), up to 10 MW under net metering, with a competitive export tariff of ₹3.56–₹4.16/unit. Ideal for large commercial rooftop projects.
Most complex for EPCs: Tamil Nadu, gross vs net metering category rules require extra diligence, and higher upfront fees reduce customer willingness. Not a reason to avoid TN, but budget extra proposal preparation time.
For EPC owners managing projects across multiple states, the operational answer is a tool that stores these parameters centrally and applies them automatically to every proposal. See how the MSEDCL process, DGVCL process, and UGVCL process work in state-specific depth.
