What Is Net Metering and How Does It Work?

Net metering is a billing mechanism that allows solar power producers to export surplus electricity to the grid. When your solar system generates more power than your factory consumes (typically during peak sunshine hours), the excess flows into the grid. Your electricity meter runs backward during this period, giving you credits.

The Three Types of Solar Metering in India

Metering TypeHow It WorksPayment for ExcessBest For
Net MeteringExcess units credited 1:1 against consumptionSame rate as grid tariffSmall-medium systems (under 500 kW)
Net BillingExcess units purchased at a lower feed-in tariff₹2–4/kWh (varies by state)Medium-large systems
Gross MeteringAll generation sold to DISCOM₹2.5–4.5/kWh fixed rateSystems designed for maximum export

Net metering is the most favorable for industrial consumers because you receive full retail tariff credit (₹8–11/kWh) for every unit exported, rather than a lower feed-in tariff.

How to Apply for Net Metering: Step-by-Step Process

Step 1: Feasibility Assessment

Before applying, ensure:

Step 2: Prepare Required Documents

DocumentDetails
Application formDISCOM-specific format
ID proofCompany PAN, GST certificate
Electricity billLast 6 months of bills
Property documentsOwnership proof or lease agreement with NOC
Single line diagramElectrical layout prepared by your EPC contractor
Equipment specificationsModule and inverter datasheets (BIS certified)
Structural stability certificateFrom a licensed structural engineer
Safety compliance certificateFrom the Chief Electrical Inspector (CEI)

Step 3: Submit Application to DISCOM

Most DISCOMs now accept online applications. Your solar EPC contractor should handle this process. Key steps:

  1. Submit application with all documents
  2. DISCOM conducts a technical feasibility study (7–15 days)
  3. Receive approval letter with technical conditions
  4. Install the solar system as per approved specifications
  5. Apply for meter installation and inspection

Step 4: DISCOM Inspection and Meter Installation

Step 5: Go Live

Once the meter is installed and the agreement is signed, your solar system starts generating credits. The first adjusted bill typically arrives within 1–2 billing cycles.

Common Net Metering Challenges and Solutions

Challenge 1: DISCOM Delays

Some DISCOMs take 60–90 days instead of the mandated 30 days. Solution: Work with an experienced EPC company like Sun Wave Technologies that has established relationships with DISCOM officials and can expedite approvals.

Challenge 2: Transformer Capacity Issues

Your local distribution transformer may not have capacity for bidirectional flow. Solution: Get a transformer capacity assessment before designing your system. You may need to limit export or upgrade the transformer (cost: ₹5–15 lakhs).

Challenge 3: Annual Settlement Loss

Excess credits settled annually at the Average Power Purchase Cost (APPC), which is ₹3–4/kWh — much lower than your grid tariff of ₹9–11/kWh. Solution: Size your system to minimize annual excess. Aim for 80–90% self-consumption ratio.

Challenge 4: Policy Uncertainty

States periodically revise net metering policies. Solution: Sign a net metering agreement that locks in your terms for 25 years. Most states grandfather existing installations under the policy active at commissioning time.

Net Metering vs. Open Access Solar

For large industrial consumers (connected load above 1 MW), open access solar may be a better alternative to net metering:

FactorNet MeteringOpen Access
System locationOn-site (rooftop/ground)Off-site (anywhere in state)
Maximum capacity500 kW–1 MW (state dependent)No upper limit
Transmission chargesNone₹1–2.5/kWh
Cross-subsidy surchargeNone₹1–2/kWh
Best forFactories with adequate roof spaceLarge consumers with limited roof space
ComplexityLowHigh (regulatory approvals needed)

Frequently Asked Questions

Can I get net metering for an industrial unit in Faridabad?

Yes. Faridabad falls under DHBVN (Dakshin Haryana Bijli Vitran Nigam), which supports net metering for industrial consumers up to 500 kW. For systems between 500 kW and 1 MW, net billing applies. Sun Wave Technologies has completed numerous net metering installations in Faridabad's industrial areas including Sector 6, Sector 24, and the Faridabad-Ballabgarh industrial belt.

How much does a net meter cost?

The bidirectional net meter typically costs ₹3,000–8,000 depending on the type (single-phase vs. three-phase) and is usually provided by the DISCOM. Some DISCOMs charge a meter installation fee of ₹1,000–5,000. Your EPC contractor handles the procurement and installation.

What happens to excess solar credits at year-end?

In most states, excess credits accumulated over the year are settled at the Average Power Purchase Cost (APPC) rate, which is typically ₹3–4/kWh. This is significantly lower than the retail tariff. That's why it's important to size your system correctly to maximize self-consumption and minimize year-end excess.

Can I get net metering with a RESCO solar installation?

Yes. Both CAPEX (EPC) and RESCO (OPEX) solar installations are eligible for net metering. In RESCO projects, the developer handles the net metering application and the credits are factored into your PPA rate.

Is net metering available for three-phase industrial connections?

Yes, net metering is available for all types of electrical connections including three-phase industrial connections. In fact, most industrial net metering installations are three-phase. The bidirectional meter must match your connection type (LT or HT).

How long does the net metering approval take in Haryana?

The official timeline is 30 days from application submission. In practice, it takes 30–45 days with DHBVN and UHBVN. Sun Wave Technologies typically completes the entire process within 35–40 days by maintaining direct coordination with DISCOM engineers and ensuring all documentation is complete at the time of submission.
