Net Metering Rules Explained (MP)

Net metering is a billing mechanism that allows solar power system owners to offset their electricity costs by feeding excess solar-generated power back to the grid. In Madhya Pradesh, this system enables residential, commercial, and industrial consumers to maximize the return on their solar investments while contributing to India's renewable energy goals. Under the Madhya Pradesh Electricity Regulatory Commission (MPERC) RG-39 regulation of 2024, consumers can install solar systems up to 500 kilowatts (kW) capacity, subject to their sanctioned load or contracted demand, whichever is lower. This policy represents a significant opportunity for citizens across the state to reduce their electricity bills while supporting India's clean energy transition.

Understanding Net Metering: How It Works

The Fundamental Concept

Net metering operates on a simple principle: your solar energy consumption is netted against the power you export to the grid. During daylight hours when your rooftop solar panels produce more electricity than you consume, the excess power flows back into the grid. The utility then credits your electricity account for this exported power. Conversely, during evening, night, and cloudy periods when your solar panels cannot generate sufficient electricity, you draw power from the grid as normal. The net billing is calculated based on the balance between power imported and exported over a billing cycle.

This system requires a bidirectional meter (also called a net meter), which can measure electricity flow in both directions. Unlike conventional unidirectional meters that only record consumption, bidirectional meters track the net energy flow in real-time, providing accurate data for billing purposes.

Practical Example

Consider a household with a 5 kW solar system in Madhya Pradesh. On a typical sunny day:

• 6:00 AM to 3:00 PM: Your solar panels generate 5 units of electricity per hour, but your household consumes only 3 units. The excess 2 units flow into the grid.
• 6:00 PM to 9:00 PM: Your solar panels produce minimal power, but your household requires 3 units, which you draw from the grid.

Under net metering, the utility calculates your net consumption by subtracting exported energy from imported energy. If you exported 2 units and imported 3 units, your net consumption is 1 unit for that period. You are billed only for this 1 unit of net consumption instead of the full 3 units you drew from the grid.

Madhya Pradesh Net Metering Regulations

Regulatory Framework and Capacity Limits

The Madhya Pradesh Electricity Regulatory Commission (MPERC) issued comprehensive net metering regulations through RG-39 (2024) in March 2024. The key regulatory framework includes:

Maximum Capacity: Consumers can install solar systems up to 500 kilowatts (kW), provided that the installed capacity does not exceed your sanctioned load (for residential consumers, typically 2-10 kW) or contracted demand (for commercial and industrial consumers).

System Size Determination: Your solar system capacity must not exceed the lower of:

• Your sanctioned load, or
• Your contracted demand with the distribution company (DISCOM)

For example, if your home's sanctioned load is 5 kW, you can install a maximum 5 kW system. For a small commercial establishment with 20 kW sanctioned load, you can install up to 20 kW.

Eligibility and Consumer Categories

All categories of consumers are eligible for net metering under MPERC RG-39 (2024):

• Residential Consumers: Individual homeowners with active electricity connections from any of Madhya Pradesh's four distribution companies—MP Poorv (Eastern), MP Madhya (Central), MP Paschim (Western), or MP Dakshan (Southern) DISCOM.
• Commercial Consumers: Retail establishments, offices, hotels, restaurants, shopping centers, and other business entities with commercial electricity connections.
• Industrial Consumers: Manufacturing units, factories, and industrial facilities consuming industrial tariff power.
• Agricultural Consumers: Farmers and agricultural enterprises operating agricultural feeders or connections.

Technical and Eligibility Requirements

Before applying for net metering, ensure you meet these mandatory requirements:

1. Active DISCOM Connection: You must have an existing, active electricity connection with one of the four Madhya Pradesh distribution companies.
2. Property Ownership or Authorization: You must be the owner or authorized occupant of the premises where the solar system will be installed. Tenants typically cannot install permanent solar systems without owner consent.
3. Grid-Connected System: Net metering is exclusively available for grid-connected (on-grid) solar systems. Off-grid or hybrid systems that operate independently are not eligible for net metering benefits.
4. Technical Compliance: Your solar installation must comply with Central Electricity Authority (CEA) guidelines and DISCOM specifications, including:
   • Solar panels meeting IEC 61215 international quality standards
   • Auto-synchronizing equipment for grid synchronization
   • String inverters with anti-islanding protection mechanisms
   • Proper earthing and electrical safety measures
   • Surge protection devices and disconnect switches
5. High-Tension (HT) Connection for Larger Systems: If your system exceeds 112 kW (but remains below 500 kW), your DISCOM connection must be on a high-tension (HT) supply, typically available only to larger commercial and industrial consumers.

Billing Mechanism and Monthly Settlement

Monthly Billing Calculation

DISCOM calculates your net electricity usage every billing cycle (typically monthly) as follows:

1. Total Imports (kWh): Sum of all units of electricity purchased from the grid during the month.
2. Total Exports (kWh): Sum of all units of electricity fed into the grid from your solar system during the month.
3. Net Consumption: Total Imports minus Total Exports.

Your billing is based on this net consumption figure.

Calculation Example

Consider a typical monthly scenario:

• Total units imported from grid: 100 kWh
• Total units exported to grid: 40 kWh
• Electricity tariff rate: ₹7 per kWh
• Net consumption: 100 - 40 = 60 kWh
• Electricity bill: 60 × ₹7 = ₹420

Without net metering, you would pay 100 × ₹7 = ₹700. Net metering reduces your bill by ₹280, representing a 40% savings in this example.

Credits and Carry-Forward Mechanism

In months when your solar system generates more electricity than you consume, excess units are carried forward to the next billing cycle as credits. These credits automatically adjust your future bills. For instance:

• January: You export 50 kWh more than you import. This creates 50 kWh of credit.
• February: You normally would consume 100 kWh, but you have 50 kWh credit from January. Your bill is calculated based on 50 kWh of net consumption.

Annual Excess Credit Settlement

At the end of the billing year (typically March 31 in India), if you still have unused credits, the DISCOM settles these at the Average Power Purchase Cost (APPC) rate:

Current APPC rate in Madhya Pradesh: Approximately ₹2.14 per kWh (rates vary annually based on renewable energy auction bids).

Settlement Example:

If you have ₹300 worth of excess credits at year-end, you receive:
₹300 ÷ ₹7 (monthly tariff) = 42.86 kWh
42.86 × ₹2.14 (APPC rate) = ₹91.71 in cash settlement

Alternatively, some DISCOMs provide credits that reset to zero if not fully utilized within the billing year. Check with your local DISCOM for their specific policy.

Fixed Charges Still Apply

Even with net metering, consumers must pay certain fixed charges irrespective of units consumed:

• Bidirectional meter rental charge (typically ₹20-50 per month)
• Demand charges (applicable to HT connections)
• Minimum service charges
• Taxes and regulatory charges

These charges appear separately on your bill and cannot be offset by solar credits.

Bidirectional Metering Infrastructure

Understanding the Bidirectional Meter

A bidirectional meter (net meter) is essential equipment for net metering. Unlike conventional meters that record only consumption:

• Bidirectional meters measure power flow in both directions simultaneously
• They record units exported to the grid separately from units imported
• They provide accurate real-time data for settlement calculations
• They comply with International Electrotechnical Commission (IEC) standards

Cost and Installation: In India, bidirectional meters typically cost ₹2,750 to ₹9,500 depending on specifications and supplier. In Madhya Pradesh, the DISCOM typically bears installation costs, though some utilities may charge consumers a one-time meter installation fee of ₹500-₹1,000.

Meter Installation and Commissioning

After your net metering application is approved, DISCOM technicians will:

1. Remove your existing meter
2. Install the bidirectional meter at your premises
3. Conduct a system test to ensure proper two-way communication
4. Document the meter reading and issue commissioning confirmation
5. Begin billing under net metering from the date of commissioning

This process typically takes 2-4 weeks from approval date.

Application Process and Regulatory Approvals

Step-by-Step Application Procedure

Obtaining net metering approval involves the following process:

Step 1: Prepare Documentation

Gather the following documents:

• Electricity bill showing your connection details and consumer number
• Copy of property ownership document (deed, title, or rental agreement for tenants)
• Government-issued ID (Aadhar, PAN, or passport)
• Technical specifications and design drawings prepared by your solar installer
• Single-line diagram showing the interconnection arrangement

Step 2: Submit Application

Submit your completed application form to your DISCOM's net metering portal or office:

• MP Poorv DISCOM (Eastern Region): www.mpez.co.in
• MP Madhya DISCOM (Central Region): www.mpcz.in
• MP Paschim DISCOM (Western Region): www.wuppd.org
• MP Dakshan DISCOM (Southern Region): www.mpups.in

You will need to pay a registration fee of ₹1,000 (typically non-refundable) at the time of application.

Step 3: Technical Scrutiny

DISCOM's technical team will review your application for:

• System capacity compatibility with your sanctioned load
• Adherence to CEA and DISCOM technical guidelines
• Proper interconnection design
• Safety and grounding arrangements

This review typically takes 2-3 weeks. You may be requested to provide additional information or modify your design.

Step 4: Conditional Approval

If your application passes technical scrutiny, DISCOM issues a Conditional Approval Letter. This letter:

• Confirms your system capacity approval
• Specifies any technical modifications required
• Outlines the timeline for commissioning
• Requests you to complete solar installation and arrange for DISCOM inspection

Step 5: Site Inspection

After you complete solar system installation, schedule an inspection with DISCOM. The inspection verifies:

• Physical installation quality and safety standards
• Proper interconnection of system components
• Compliance with electrical codes and safety regulations
• Anti-islanding protection functionality
• Proper grounding and surge protection

Step 6: Execute Interconnection Agreement

After successful inspection, you must sign the Net Metering Interconnection Agreement with DISCOM. This legal document specifies:

• Terms and conditions of net metering
• Your obligations regarding system maintenance
• DISCOM's responsibilities
• Disconnection procedures and penalties
• Dispute resolution mechanisms

Step 7: Final Commissioning and Meter Installation

DISCOM installs your bidirectional meter and conducts final system testing. Once approved, your system is synchronized with the grid and net metering billing commences.

Total Timeline: This entire process typically takes 6-12 weeks from initial application to commissioning.

Alternative Net Metering Arrangements

Group Net Metering (GNM)

For consumers with multiple properties, Group Net Metering offers significant advantages:

How It Works:

• One large solar system is installed at a single location
• Generated power is distributed among multiple connected properties
• All properties are treated as a single billing unit
• Excess generation from any property can compensate consumption at another property

Capacity Limits:

• Maximum capacity: Five times the total sanctioned load of all grouped properties (up to 10 MW absolute maximum)

Advantages:

• Larger, more economical solar systems
• Better capacity utilization
• Reduced per-unit installation costs through economies of scale
• Centralized system maintenance

Example: A commercial entity with a main office building (10 kW sanctioned load) and two branch offices (5 kW each) can install a combined 100 kW system under GNM (5 × 20 kW total load).

Virtual Net Metering (VNM)

For renters and consumers without suitable rooftop space, Virtual Net Metering enables participation:

How It Works:

• A shared solar installation is built at a convenient location
• Power generated is virtually distributed among multiple consumers
• Each consumer is allocated a percentage of generation based on their agreement
• Individual billing reflects each consumer's allocated generation

Use Cases:

• Apartment complexes and condominiums
• Commercial complexes with multiple tenants
• Communities without individual rooftop space

Advantages:

• Enables solar participation without rooftop ownership
• Reduced per-consumer investment
• Scalable for large residential developments

Renewable Energy Obligations and Compliance

Renewable Purchase Obligation (RPO)

An important policy context for net metering is India's Renewable Purchase Obligation (RPO):

What is RPO?

• DISCOMs are mandated to purchase a certain percentage of electricity from renewable sources
• In Madhya Pradesh, the RPO target is approximately 17% renewable energy by 2025-26
• Your net-metered solar generation contributes toward DISCOM's RPO compliance

Your Benefit:

• Your solar generation counts toward RPO, making utilities more committed to prompt net metering approvals
• DISCOMs often prioritize renewable consumers to meet RPO targets
• Policy stability ensures long-term support for net metering

Critical Limitations and Restrictions

What Net Metering Does NOT Allow

Understanding these restrictions is crucial for realistic expectations:

1. Cannot Sell Power to Third Parties: You cannot directly sell your solar-generated electricity to another consumer or commercial entity. All power must flow through the DISCOM grid, and billing is managed solely by DISCOM. Direct power purchase agreements are a separate process and not covered under net metering.
2. Off-Grid Systems Ineligible: Systems designed to operate independently (completely off-grid) cannot avail net metering benefits. The system must remain grid-connected at all times.
3. No Capacity Oversizing: Your system capacity cannot exceed your sanctioned load. DISCOM will reject applications exceeding this limit, regardless of grid capacity.
4. Continuous Grid Connection Mandatory: Your system must remain connected to the grid. Deliberately disconnecting or attempting to disable grid connection may result in penalties and disconnection.

Other Important Restrictions

• No storage mandate removal: While you can use batteries for backup, this doesn't change your net metering eligibility
• Technology restrictions: Only solar PV systems currently qualify; other renewable sources like wind are handled separately
• Connection stability required: Frequent disconnections or system faults may result in net metering suspension

Excess Power Credit Settlement Rates

Current APPC Rates in Madhya Pradesh

For excess credits settled annually at APPC rates:

These rates fluctuate annually based on renewable energy auction outcomes. MPERC publishes updated APPC rates each fiscal year (April 1).

How to Calculate Your Annual Settlement

Example Calculation:

Assume you have a net monthly credit (after accounting for all imports/exports) of:

• January: ₹100 credit → used in February
• February: ₹150 credit → used in March
• ...continuing through March
• Total unused credit at year-end (March 31): ₹250

Settlement:

• ₹250 ÷ ₹7 per kWh (your tariff) = 35.7 kWh
• 35.7 kWh × ₹2.14 (APPC rate) = ₹76.40 in cash settlement

Technical and Safety Requirements

Mandatory Safety Standards

Your solar system must comply with these standards:

• IEC 61215: International standard for solar panel efficiency and quality
• IEC 61730: Safety requirements for photovoltaic modules
• IEEE 1547: Standard for interconnection of distributed resources
• IS 3043: Indian standard for earthing and bonding for electrical installations
• IS 7638: Protection of equipment from lightning

Grid Synchronization Requirements

• Frequency synchronization: System must maintain ±1 Hz frequency sync with grid
• Voltage compliance: System voltage must be ±10% of nominal grid voltage
• Anti-islanding: Inverter must disconnect within 2 seconds if grid fails
• Harmonics compliance: Total harmonic distortion <5%< /li>

Reputable solar installers ensure all these requirements are met during commissioning.
