Is Net Metering Available Everywhere in India? Rules and Conditions

Net metering strongly affects the economics of a grid-connected rooftop solar system. It lets a home use solar electricity during the day and receive an adjustment for surplus energy exported to the grid. However, the same rules do not apply everywhere in India.

India has a national rooftop-solar framework, but State Electricity Regulatory Commissions and electricity distribution companies, commonly called DISCOMs, determine detailed eligibility, billing, capacity limits and settlement. Here is what homeowners can usually expect, along with the main benefits and limitations.

Net-metering availability, billing and capacity conditions vary between Indian states and DISCOMs.

This overview reflects official information available in July 2026. Regulations can change, so homeowners should verify the latest order applicable to their state and electricity connection.

Is Net Metering Available Throughout India?

Net metering is supported nationally, but it is not a uniform facility with identical terms in every state and DISCOM area.

The Electricity (Rights of Consumers) Rules recognise a consumer’s right to install renewable energy and require State Commissions to regulate grid-interactive rooftop solar. A 2021 amendment created a fallback under which a Commission may allow net metering up to 500 kW or the consumer’s sanctioned load, whichever is lower, where regulations do not already specify an arrangement.

State rules may still prescribe net metering, net billing or gross metering for different consumer categories and system sizes.

For homeowners, net metering is commonly provided for residential rooftop solar, but approval is connection-specific and the financial treatment varies. An application may also be limited by sanctioned load, local network capacity, transformer conditions or DISCOM rules.

How Does Net Metering Work?

A bidirectional meter records electricity flowing in both directions:

• Import: Energy drawn from the grid, measured in kilowatt-hours or kWh.
• Export: Surplus solar energy sent to the grid, also measured in kWh.

Eligible exports are adjusted against imports according to the applicable billing rules.

For example, suppose a home imports 300 kWh and exports 180 kWh during the relevant accounting period. Its energy balance may be 120 kWh of net import.

However, fixed charges, meter charges, electricity duty or other tariff components may still remain payable.

Net Metering vs Net Billing and Gross Metering:

Under net billing, imported electricity and exported solar electricity are valued separately, often at different rates. The export rate may be lower than the retail tariff paid for imported electricity.

Under gross metering, all solar generation is exported under the approved arrangement. The consumer’s complete electricity consumption is then billed normally.

These arrangements can produce very different savings, even when the rooftop system generates the same number of units.

What Are the Usual Net-Metering Conditions?

1. An Eligible Grid-Connected Connection

The applicant generally needs an active electricity connection in the correct name and consumer category.

The solar PV system must be installed at the approved premises and connected at the authorised point of supply. Ownership, tenancy or roof-use documents may be required depending on the DISCOM procedure.

2. Capacity Within the Permitted Limit

System capacity is normally limited by the consumer’s sanctioned load or contract demand and any additional cap in the state regulation.

For example, a homeowner with a sanctioned load of 3 kW should not assume that a 5 kW net-metered system will be approved without first increasing the sanctioned load.

The 500 kW limit in the central framework is not an automatic entitlement to install a system of that size. The lower sanctioned-load limit, state regulations and network feasibility continue to matter.

3. Application and DISCOM Approval

Applications are generally submitted through the national rooftop-solar portal, a state portal or the relevant DISCOM’s process.

National consumer rules require DISCOMs to provide application, tracking, metering and commissioning procedures for rooftop-solar consumers.

Under the February 2024 central amendments:

·        Systems up to 10 kW are exempt from a technical-feasibility study.

·        For larger systems, the study should be completed within 15 days, failing which feasibility is presumed.

·        Distribution-system strengthening costs for systems up to 5 kW are to be borne by the distribution licensee.

·        The DISCOM commissioning timeline was reduced to 15 days after the required installation documents are submitted.

Homeowners should still confirm how these provisions have been incorporated into the local DISCOM workflow.

4. Compliant Metering and Protection

A grid-connected system must use appropriate equipment, including:

·        a compliant solar inverter;

·        bidirectional and generation meters where required;

·        AC and DC isolation;

·        suitable earthing;

·        surge and electrical protection; and

·        anti-islanding protection.

Installation and testing should be handled by qualified solar and electrical professionals.

CEA guidance requires a grid-tied inverter to shut down during a grid blackout. This prevents the rooftop system from unintentionally energising electricity lines while utility personnel may be working on them.

Consequently, an ordinary grid-connected solar system does not provide backup during an outage. Backup requires a properly designed hybrid or battery-based system with an approved backup arrangement.

5. Inspection and Commissioning

After installation, the consumer generally submits completion certificates and other required documents.

The DISCOM may inspect the system, test or replace the meter, execute an interconnection agreement and issue commissioning approval. Electricity should not be exported before the required approval and metering process is completed.

6. State-Specific Settlement Rules

The financial value of net metering depends heavily on the settlement provisions. Before buying, check:

·        whether export credits are adjusted monthly;

·        whether credits can be carried forward;

·        the annual or other settlement period;

·        how year-end surplus is compensated;

·        whether unused credits lapse;

·        whether time-of-day accounting applies; and

·        which fixed charges, duties and fees remain payable.

Benefits of Net Metering for Homeowners:

Net metering can improve rooftop-solar economics because daytime surplus is recorded for adjustment rather than remaining unused. This is valuable for households where occupants are away during peak solar-generation hours.

It can also reduce the need to purchase a battery solely for electricity-bill savings. The grid performs an accounting role for imported and exported energy, although it is not a physical storage system and cannot provide outage backup.

Net metering is generally most useful when the solar plant is sized close to household consumption and export-credit rules are favourable.

Actual savings depend on location, solar irradiation, system size, roof orientation, shading, equipment quality, household load pattern, electricity tariff, system losses and the applicable billing rules.

Limitations and Common Misunderstandings:

Regulatory variation is the biggest limitation. A quotation that assumes full retail-tariff credit for every exported unit may be misleading where net billing, a lower surplus-purchase rate or a limited carry-forward period applies.

Oversizing may also reduce financial returns. A large annual surplus can be worth less than electricity consumed directly inside the home.

Network constraints can delay or restrict approval where many rooftop systems already export through the same distribution transformer.

Homeowners may also encounter meter costs, application charges, documentation delays or incorrect billing after commissioning.

Most importantly, net metering does not automatically make an electricity bill zero. Night-time imports, seasonal generation differences, fixed charges and other tariff components remain relevant.

What Should Homeowners Verify Before Buying?

Ask the installer for the latest regulation or DISCOM circular applicable to your consumer number—not merely a statement that “net metering is available”.

Confirm the:

• permitted solar-system size;
• sanctioned-load requirement;
• metering arrangement;
• export-credit treatment;
• settlement period;
• expected meter and application charges; and
• approval and commissioning process.

The system should be sized using at least 12 months of electricity bills and a realistic roof assessment.

Never alter meters, wiring, isolators or protection devices yourself. Use a qualified solar installer and licensed electrical professionals for all grid-connected work.

Conclusion:

Net metering is part of India’s rooftop-solar framework, but it is not offered on identical terms everywhere. Residential consumers commonly have access subject to state regulations, DISCOM procedures, sanctioned load and local network conditions.
