Net Metering (India)

Net metering in India lets rooftop solar customers offset grid imports with exports. State-wise caps, tariffs, and DISCOM application process.

Quick answer

Net metering in India is a billing arrangement in which a rooftop solar consumer exports surplus power to the DISCOM grid and is billed only for net consumption, measured by a bidirectional meter. The Electricity (Rights of Consumers) Rules, 2020 set the national framework, while each State Electricity Regulatory Commission sets local capacity limits and settlement terms.

Application Workflow

  1. Site survey by certified installer.
  2. Online application via DISCOM portal (BESCOM, MSEDCL, etc.).
  3. Technical feasibility approval (2-4 weeks).
  4. Sanction letter with capacity approval.
  5. Installation of MNRE-spec equipment (ALMM-listed modules, BIS-certified inverter).
  6. CEIG inspection for ≥10 kW systems, Heaven Designs prepares the CEIG-compliant electrical drawing package most DISCOMs ask for at this stage.
  7. Bidirectional meter installation by DISCOM.
  8. Net metering agreement signing.
  9. PTO and energization.

Common Mistakes

  1. Specifying inverter not on DISCOM’s approved list.
  2. Module not ALMM-listed.
  3. Wrong sanction load assumption (capacity cap is % of sanctioned, not max load).
  4. Missing CEIG approval for ≥10 kW.
  5. Underestimating banking/wheeling charges in commercial solar ROI models.

Best Practices

  • Verify state-specific cap, banking, and tariff before quoting.
  • Confirm inverter is on the specific DISCOM’s approved list (not just MNRE).
  • Apply for net metering before purchasing equipment.
  • Use a state-empaneled installer for documentation acceptance.

Key Takeaways

  • Net metering in India varies state by state, caps, banking, tariffs differ widely.
  • Most states cap individual systems at 100% of sanctioned load, up to 1 MW.
  • Tamil Nadu and a few states restrict net metering to small residential; gross metering for larger.
  • Required steps: DISCOM application → CEIG approval → installation → meter exchange → PTO.
  • Verify with specific DISCOM, not generic state policy, before specifying equipment or pricing the project.

Net metering rules are only one piece of getting a rooftop system permitted and energized, our state-wise breakdown of solar permit processing times in India walks through how the DISCOM application and CEIG timelines here interact with overall project scheduling.

For a plain-language explainer aimed at homeowners rather than EPCs, Heaven Green Energy’s net metering guide covers the same mechanism from the customer’s side of the bill. If you’re structuring the commercial paperwork around a system, the Solar Permit Design service page details what a complete DISCOM submission package needs beyond the net metering agreement itself.

Frequently Asked Questions

4 commonly searched questions about Net Metering (India).

Does every Indian state offer net metering?
Every state has rooftop solar metering regulations, but the details vary. Each State Electricity Regulatory Commission sets capacity caps, eligible consumer categories, and whether net metering, net billing, or gross metering applies. Designers check the current state regulation and DISCOM rules before sizing a system.
What is the difference between net metering and gross metering?
Under net metering, exported units offset imported units and the consumer pays for the net amount. Under gross metering, all solar generation is sold to the DISCOM at a fixed tariff and all consumption is billed separately at the retail rate. Settlement terms differ by state.
What is the net metering application process?
The consumer applies on the DISCOM's rooftop solar portal, receives technical feasibility approval, and installs the system through a registered vendor. The DISCOM then inspects the plant, installs the bidirectional meter, and commissions the connection. Larger systems may also need Electrical Inspector approval.
What happens to surplus net metering credits?
Most state regulations let surplus units carry forward within a billing year. At the end of the settlement period, any remaining surplus is typically paid at a tariff set by the regulator, often well below the retail rate. Rules differ by state, so check the current order.
