Net Metering in India
Net metering in India has become a key policy mechanism supporting the adoption of rooftop solar systems across residential, commercial, and industrial sectors. As India continues to expand its renewable energy capacity, net metering enables consumers to generate their own electricity while efficiently utilizing excess energy through grid interaction.
With rising electricity tariffs and increasing demand for clean energy, net metering provides a practical solution for businesses to reduce energy costs and improve sustainability. The policy allows solar system owners to export surplus electricity to the grid and receive credits, making solar investments more financially viable.
Government initiatives and regulatory frameworks across states have further strengthened net metering adoption, although policies vary based on state electricity regulations and system capacity limits.
What is Net Metering and How It Works?
- Net metering is a billing mechanism that allows solar system owners to offset their electricity consumption by exporting excess power to the grid.
- How it works:
- Solar panels generate electricity during the day
- Excess energy is exported to the grid
- A bidirectional meter records import and export units
- Consumers are billed only for net energy consumption
Net Metering vs Gross Metering
| Parameter | Net Metering | Gross Metering |
|---|---|---|
| Energy Usage | Self-consumption prioritized, excess exported | Entire energy exported to grid |
| Billing Mechanism | Consumer billed on net consumption (import minus export) | Consumer buys all electricity from grid separately |
| Savings Potential | Higher savings due to direct consumption offset | Lower savings, depends on feed-in tariff |
| Ideal Use Case | Industrial, commercial, and residential users | Utility-scale or large solar producers |
| Tariff Structure | Retail tariff offset | Fixed feed-in tariff decided by DISCOM |
| ROI | Faster payback period | Slower return on investment |
| Grid Dependency | Partial dependency | Full dependency on grid for consumption |
| Policy Availability | Widely available but state dependent | Limited and used in specific cases |
| Complexity | Moderate setup and approvals | Simpler billing but less beneficial |
| Financial Benefit | More cost-effective for businesses | Suitable for power producers, not consumers |

Net Metering Charges and Cost Structure in India - 2026
| Cost Component | Details |
|---|---|
| Application Fee | ₹500 to ₹5,000 depending on state DISCOM and system capacity |
| Net Meter Cost | ₹2,000 to ₹10,000 (some states subsidized or included in DISCOM charges) |
| Inspection Charges | ₹0 to ₹5,000 depending on DISCOM policies |
| Agreement Charges | Nominal or included in application fees |
| Grid Synchronization Cost | Usually included in installation, but may vary |
| Annual Charges | Some states impose fixed service or meter rent charges (~₹500–₹2,000/year) |
| Solar Installation Cost | ₹35–₹55 per watt (commercial scale, varies by technology and capacity) |
- Key Insights:
- Many states are reducing upfront charges to encourage rooftop solar adoption.
- Some DISCOMs now bundle net meter cost within project approval fees.
- Industrial-scale systems (100 kW – 500 kW) see economies of scale, reducing per watt cost.
- Time-of-Day (ToD) tariffs are being introduced in some states, impacting export value.
