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 state-by-state net metering charges that regulators' and DISCOMs' own documents state (checked 31 October 2026): application fees, meter costs, export and settlement rules, banking charges and wheeling charges. Where we could not open a current official document, the table says "Not verified" instead of guessing, so your teams quote from fact, not assumption.
KEY TAKEAWAY
Net metering charges vary significantly by state and DISCOM. The application fee is Rs 1,000 to Rs 5,000 in West Bengal (by voltage) and Rs 2,500 to Rs 15,000 in Telangana (LT to HT), and surplus units are settled very differently: Telangana pays a notified rate every month, while West Bengal resets leftover net-metering units to zero at the end of the year. Gujarat's regulations were replaced on 30 October 2026, and Maharashtra's grid support charge starts once rooftop capacity reaches 5,000 MW. Understanding these differences before you quote allows you to 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, so it pays to study the state-by-state DISCOM net metering process before standardising your quoting logic. A wrong 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 | Paid by the prosumer in the regulations we opened (Telangana, West Bengal) | Paid by the prosumer; a separate generation meter or check meter is needed (West Bengal reg 9) |
| Who typically uses it | Residential, small commercial (majority of states) | Large C&I and generation-first investors, where the state allows it |
| Banking of surplus units | Allowed (monthly or annual, state-dependent) | Not applicable; generation is paid at the feed-in tariff (West Bengal pays the net amount at the end of the settlement period) |
| Better for whom | Residential consumers with significant self-consumption | Large generators where feed-in tariff > retail rate |
EPC note. The PM Surya Ghar guidelines (July 2025, clause 6(l)) say that all metering arrangements approved by the State Commission (net metering, gross metering, net billing, virtual net metering, group net metering) are covered under the scheme. If a DISCOM insists on an arrangement your State Commission's regulation does not provide for, raise it through the national portal's grievance route (clause 11) or with the DISCOM's Consumer Grievance Redressal Forum.
State-by-state: net metering application fees and one-time charges
The table below consolidates charges for the major DISCOM zones. Charges are for residential/LT consumers unless stated. Always verify with the specific sub-division office as tariff orders update annually, and see the step-by-step net metering application process for how these charges fit into the overall timeline. For West Bengal's 2025 fees in full, see the WBSEDCL net metering application guide.
| State / DISCOM | Application fee | Meter and other one-time charges | Regulatory reference |
|---|---|---|---|

Important. Where a cell says "Not verified", we could not open a current official document for it, so we show no figure. Charges also change with each regulation and tariff order. Always request the current charge schedule from the local DISCOM office or download the latest order from the 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 one of the biggest variables in the payback period calculation, so model it with your customer's own numbers. Study this table carefully before quoting, and cross-check it against solar payback period by state for the full financial picture.
| State / DISCOM | Export tariff structure | Effective rate | Banking period | Surplus settlement |
|---|---|---|---|---|
| Gujarat (all 4 DISCOMs) | Not verified for net metering under the 2026 regulations | Not verified | Not verified | Virtual net metering: residential surplus deemed purchased at Rs 2.25/kWh or the rate the Commission specifies (DRES 2026, clause 9.5.4) |
| Maharashtra, MSEDCL | Time-of-day slot banking under MERC's order of 25 Mar 2026 (Case 75 of 2025) | Not verified | Energy banked in the solar-hours slot (09:00 to 17:00) may be drawn in that slot; residential consumers exempt from slot-wise banking for rooftop net metering | Not verified |
| Karnataka, BESCOM | Not verified | Not verified | Not verified | Not verified |
| Tamil Nadu, TANGEDCO | Not verified | Not verified | Not verified | Not verified |
| Delhi, BSES Rajdhani / Yamuna / TPDDL | Group net metering: surplus adjusted against other connections in the consumer's priority list; virtual net metering: credit by the ratio in the agreement (DERC guidelines) | Not verified | Not verified | Not verified |
| Rajasthan, Uttar Pradesh, Andhra Pradesh | Not verified | Not verified | Not verified | Not verified |
| Telangana, TGSPDCL / TGNPDCL | Exports above imports settled at the lowest tariff in solar PPAs the DISCOMs signed in the preceding financial year, notified by the Commission each year | Notified yearly | Monthly | Adjusted in the next month's bill or paid to the bank account; a monthly minimum bill applies if exports exceed imports (clause 8.1.3) |
| West Bengal, WBSEDCL / CESC | Net metering: surplus carried forward. Net billing: exports valued at the feed-in tariff. Gross metering: all generation paid at the feed-in tariff | Feed-in tariff for 2025-26: Rs 4.37 (L&MV), Rs 3.89 (HV), Rs 3.73 (EHV) per kWh | Settlement period generally 1 April to 31 March | Net metering: leftover net exported energy reset to zero. Gross metering: net amount receivable paid at the end of the settlement period |
Delhi note. We could not verify Delhi's ordinary net metering export rate, so we do not quote one. What we did verify is DERC's group and virtual net metering rule: systems commissioned till 31 March 2027 are exempt from wheeling, banking, cross-subsidy surcharge and other charges for their useful life, and a rising share applies after that. Factor the commissioning date into any Delhi proposal that uses those arrangements.
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) | Virtual net metering participants: wheeling charges and losses per GERC's Green Energy Open Access Regulations, 2024 (DRES 2026, clause 10.4). Ordinary net metering: not verified | Virtual net metering: none for residential consumers; non-residential banking up to 30% of energy drawn, subject to banking charges | Virtual net metering: applies unless captive criteria are met; 25% concession if the consumer lets the DISCOM use the RE attribute | Check the 2026 text for your arrangement |
| Maharashtra (MSEDCL) | Virtual net metering: open access charges and losses exempted until installed rooftop capacity in the state reaches 5,000 MW (Second Amendment, reg 11.10(e)) | Not verified | Not verified | MERC's order of 25 Mar 2026 sets a Grid Support Charge once 5,000 MW is reached: Rs 1.40 (HT) and Rs 1.88 (LT) per unit of generation for FY26, Rs 1.42 and Rs 1.96 for FY27; installations up to 10 kW are exempt. We have not verified whether MSEDCL is billing it |
| Karnataka (BESCOM) | Not verified | Not verified | Not verified | Not verified |
| Tamil Nadu (TANGEDCO) | Not verified | Not verified | Not verified | Not verified |
| Delhi (BSES / TPDDL) | Group and virtual net metering: exempt from wheeling, banking, cross-subsidy surcharge and other charges for systems commissioned till 31 Mar 2027, for their useful life | Same exemption | Same exemption; for systems commissioned till 31 Mar 2030, 25% of the charges is levied, rising in 25% steps every third year (DERC Fifth Amendment, 2024) | Exemption shrinks with the commissioning date |
| Rajasthan, Uttar Pradesh, Andhra Pradesh, Telangana | Not verified | Not verified | Not verified | Not verified |
| West Bengal (WBSEDCL, CESC) | Not found in the net metering regulation text we read | Not found | Not found | Net metering surplus resets to zero at period end |
Gujarat DISCOM comparison, DGVCL vs MGVCL vs PGVCL vs UGVCL
All four Gujarat DISCOMs operate under the same GERC regulations. GERC's Grid Interactive Distributed Renewable Energy Sources Regulations, 2026 are listed on its site as notified on 30 October 2026 and repeal the 2016 rooftop regulations, so the charges and limits for Gujarat should be re-checked against the new text.
| DISCOM | Area Served | Time limits | Portal | Guide |
|---|---|---|---|---|
| DGVCL | South Gujarat, Surat, Bharuch, Navsari, Valsad, Tapi, Dang, Narmada | Same GERC limits for all four (see the state table above) | DISCOM's own website | DGVCL NM guide |
| MGVCL | Central Gujarat, Vadodara, Anand, Kheda, Panchmahals, Dahod | Same GERC limits | DISCOM's own website | MGVCL NM guide |
| PGVCL | Paschim (West) Gujarat, Rajkot, Junagadh, Porbandar, Jamnagar, Amreli | Same GERC limits | DISCOM's own website | PGVCL NM guide |
| UGVCL | North Gujarat, Mehsana, Patan, Gandhinagar, Sabarkantha, Banaskantha | Same GERC limits | DISCOM's own website | UGVCL NM guide |
Gujarat EPC advantage. Because all four Gujarat DISCOMs operate under the same GERC regulations, a Gujarat-focused EPC can keep a single proposal template for net metering charges and switch the DISCOM name. Multi-state operations need a different charge input for every state.
System capacity limits for net metering by state
Not all states allow unlimited capacity under net metering, and the caps below are from the regulation texts we opened. 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): Under GERC's DRES Regulations, 2026 (listed as notified 30 Oct 2026), net metering covers 1 kW to 1,000 kW (AC); gross metering 6 to 4,000 kW; group net metering 6 to 1,000 kW; virtual net metering 10 to 4,000 kW (AC). Most residential systems are 1 to 10 kW and fall well within the limits.
-
2
Maharashtra (MSEDCL): Net metering capacity is limited to 5 MW or the consumer's contract demand or sanctioned load, whichever is lower (MERC First Amendment, 2023, as set out in its Statement of Reasons of 16 Nov 2023; the earlier limit was 1 MW). We read the amended text there, not the consolidated regulation, so confirm the current consolidated text for large systems.
-
3
Karnataka (BESCOM): Not verified. KERC's site did not load when we checked, so we state no cap. BESCOM's Common SOP (file dated 17 Oct 2025) treats distributed solar applications up to 150 kW as deemed feasible and sends larger ones for feasibility review.
-
4
Tamil Nadu (TANGEDCO): Not verified: we could not open the current TNERC regulation. Confirm consumer's tariff category with TANGEDCO before advising net vs gross metering, ideally by walking through TANGEDCO's net metering procedure for the connection type in question.
-
5
Delhi (BSES / TPDDL): Ordinary net metering limits: not verified. DERC's 2019 group and virtual net metering guidelines set a 5 kW minimum, and after the 2024 amendment there is no cap on rooftop solar under either arrangement; ground-mounted capacity is limited to 5 times the participants' sanctioned load, up to 10 MW.
-
6
Telangana and West Bengal: Telangana allows net metering up to 500 kWp and generally caps capacity at 100% of sanctioned load for residential and government consumers and 80% of sanctioned load or contract demand for others (TGERC Regulation 1 of 2025). West Bengal allows 1 kW up to 500 kW or the contract demand or sanctioned load, whichever is lower (WBERC Regulations, 2025). Rajasthan, UP and Andhra Pradesh: not verified. UP's DISCOMs are PVVNL, MVVNL, PuVVNL and KESCO, so confirm the right one for your project location.
Pros and cons of net metering for EPCs operating across multiple states
ADVANTAGES FOR EPC BUSINESS
- Net metering is a familiar arrangement, so what you learn in one state carries over
- Up to 10 kW, a complete application is deemed accepted without a feasibility study under the central Rules
- PM Surya Ghar guidelines cover every metering arrangement the State Commission has approved
- Bidirectional meter cost is a one-time charge, not a recurring burden on customer economics
- Where the state publishes a notified rate or feed-in tariff, you can model payback from a documented number
- The central Rules give every state a floor: 15-day limits and compensation of at least ₹500 a day for unjustified delay
CHALLENGES FOR EPC BUSINESS
- Charges differ per state, manual proposal building leads to quoting errors at scale
- Regulations and tariff orders change (Gujarat's were replaced on 30 Oct 2026), so last year's figures may already be outdated
- Procedures differ by state, and it's worth briefing your sales team on common reasons DISCOMs reject net metering applications so avoidable errors don't stall a project
- Application fees and meter costs need to be built into customer pricing
- Surplus settlement can be well below retail or zero (West Bengal), which affects payback accuracy
- Group and virtual arrangements can attract wheeling, banking and CSS charges (see the table above), which reduces returns on large installations
How Quickest Solar CRM handles multi-state net metering charges in proposals
For a scaling EPC running projects across several states, tracking state-wise net metering charges, export rules and banking rules is a proposal-quality risk. Quickest Solar CRM does not look these up for you, so keep a dated sheet of the figures above and use the CRM to carry them into every proposal. Here is what it does cover:
- → Proposal templates: A proposal PDF with your logo, items, product photos, and terms and conditions. Put the state's current fee and settlement rule in your terms so every proposal states them the same way.
- → Price list with margin: The admin sets the price list with margin, so you can add the meter and application charge as a separate item on the proposal, visible to the customer.
- → PM Surya Ghar subsidy in the proposal: For empanelled PM Surya Ghar vendors, the subsidy is applied in the proposal. The net metering rate and payback assumptions are yours to add.
- → Lead stages for approvals: Create customisable lead stages and labels for the net metering application steps, filter leads by stage, and set follow-up reminders, relevant when managing DISCOM approval processes across multiple states.
- → Team report: The dashboard and team report show your team's leads and activity, and a filter on the "awaiting net meter" stage keeps post-installation follow-up from falling 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 come from the regulator and DISCOM documents named in the tables, checked on 31 October 2026. Regulations and tariff orders change. Before including any charge figure in a customer proposal, verify against the latest SERC order or the DISCOM's official charge schedule:
- Gujarat: gercin.org (GERC, renewable energy regulations list)
- Maharashtra: merc.gov.in (MERC, Maharashtra Electricity Regulatory Commission)
- Karnataka: kerc.karnataka.gov.in (KERC, Karnataka Electricity Regulatory Commission)
- Tamil Nadu: TNERC, Tamil Nadu Electricity Regulatory Commission (we could not open its site, so no link)
- Delhi: derc.gov.in (DERC, Delhi Electricity Regulatory Commission)
- Telangana: TGERC Regulation 1 of 2025 (copy on TGSPDCL's site)
- West Bengal: WBERC Regulations, 2025 (copy on WBSEDCL's site)
- National solar portal for PM Surya Ghar: pmsuryaghar.gov.in
Summary: what the verified documents show
We cannot name a single most favourable state, because we could not verify the tariff data for every state. Here is what the verified documents show:
Clearest published settlement rule: Telangana, which settles exports above imports every month at a notified rate (the lowest solar PPA tariff of the preceding year).
Lowest published application fee: West Bengal at ₹1,000 for LV and MV (Telangana is ₹2,500 for LT). Gujarat's fee schedule needs checking against the 2026 regulations.
Largest net metering ceiling we verified: Maharashtra at 5 MW or contract demand or sanctioned load, whichever is lower, against 1,000 kW (AC) in Gujarat's 2026 regulations and 500 kW or kWp in West Bengal and Telangana.
Watch closely: Gujarat (new regulations, 30 Oct 2026), Maharashtra (Grid Support Charge once rooftop capacity reaches 5,000 MW) and West Bengal (leftover net-metering units reset to zero).
For EPC owners managing projects across multiple states, the operational answer is a dated sheet per state that your team updates whenever a regulation changes. See how the MSEDCL process, DGVCL process, and UGVCL process work in state-specific depth.
