Net metering is a system that allows you to generate your own electricity using solar panels and send any extra power back to the national grid. This means you can earn credits for the excess energy your solar system produces, which then lowers your electricity bills. It gives you a way to reduce costs and use clean energy without relying completely on traditional power sources.
In Pakistan, net metering is supported by government policies that encourage more people and businesses to install solar panels. When your panels create more electricity than you use, the extra goes to the grid, and you get credited for it. Later, when your system produces less power, you can use those credits to offset your energy costs.
Understanding how net metering works can help you decide if solar power is a smart choice for your home or business. This system is part of a bigger effort in Pakistan to shift towards renewable energy and reduce electricity expenses for consumers.

Understanding Net Metering
Net metering lets you manage how you use and share electricity from renewable sources like solar panels. It changes the way your electric meter works and impacts your bills. Its history shows why it became popular around the world.
Definition of Net Metering
Net metering is a billing system that credits you for the extra electricity your solar panels or renewable setup send back to the grid. When your system produces more power than you use, the surplus flows to the electric company’s network.
You earn credits for this extra energy. Later, when your panels produce less electricity, you can use these credits to lower your bills. This setup helps you save money and encourages clean energy use without needing to store power in batteries.
How Net Metering Differs from Traditional Metering
Traditional metering measures only how much electricity you consume from the grid. It does not account for any electricity you produce. Your meter runs only when you draw power, so you pay for every unit used.
With net metering, your meter runs backward when you send electricity to the grid, effectively reducing your total consumption charges. It balances the power you use with what you put back, so you pay only for the net amount.
This system can reduce your overall electricity costs and gives you some control over your energy expenses.
History and Global Adoption of Net Metering
Net metering began in the late 1970s in the United States as solar technology grew. It became a way to help homeowners and businesses save on energy costs while promoting renewable energy.
Today, many countries use net metering, including Pakistan. Pakistan started adopting net metering to support solar energy and reduce reliance on traditional power sources. It fits well with the growing renewable energy goals there and benefits people by making solar power more affordable and practical.
How Net Metering Works in Pakistan
Net metering in Pakistan lets you produce your own electricity using solar energy and send extra power back to the grid. This system helps you save on electricity bills and get credits for surplus energy. You need to meet certain rules, follow a set process, and use approved types of renewable systems.
Eligibility and Requirements
To participate in net metering, you must have a valid electricity connection, typically a three-phase connection. Your solar system size should be between 1 kW and 1 MW. Your property must be eligible under NEPRA’s rules, and the system should be connected directly to your meter.
You need to have proper wiring and meet technical standards. Your solar setup should be certified and comply with Pakistan’s electrical safety codes. A green meter, installed by the distribution company (DISCO), is mandatory to measure both consumption and exported electricity. You must be a registered consumer of a DISCO in Pakistan to apply.
Application and Approval Process
You start by submitting an application to your local DISCO. This requires details about your solar system, property, and existing electricity connection. After submission, the DISCO inspects your site and verifies your system meets all standards.
Once approved, they install a bi-directional meter or green meter. This meter tracks the electricity you consume and the excess you supply to the grid. You will receive credits for any surplus energy sent back. The entire process can take a few weeks, depending on the DISCO’s workload and your documentation.
Types of Renewable Energy Systems Allowed
Net metering in Pakistan mostly supports solar photovoltaic (PV) systems. These are the most common and practical for residential and commercial use. The system must generate clean, renewable electricity that complies with local standards.
Other types of renewable energy like wind or small hydropower are not typically included under current net metering regulations. Your solar panels must be connected to the grid safely, with approved inverters and equipment. This ensures you generate usable power and maintain grid stability.
Technical Aspects of Net Metering
Net metering involves specific technical setups that help you generate, measure, and exchange electricity with the grid efficiently. You must install the right equipment and follow safety rules to connect your renewable energy system properly. Ongoing monitoring ensures your system works well over time.
Bidirectional Metering System
The core of net metering is a bidirectional electricity meter. This meter tracks the electricity you use from the grid and the excess power your solar panels send back.
It runs both ways:
- When your panels produce more power than you need, the meter credits you for this extra energy.
- When your use exceeds production, it measures how much power you draw from the grid.
This system allows you to offset your electricity bill by the amount of clean energy you supply. The bidirectional meter must be installed by authorized technicians and approved by your electricity provider to ensure accurate readings.
Grid Connectivity and Safety Standards
Your solar or renewable energy system must meet strict grid connection and safety standards before it can feed energy into Pakistan’s electricity network. You need to use approved inverters that convert your solar energy from DC to AC compatible with the grid.
These standards protect both you and the power grid from faults or damage, such as:
- Avoiding backfeed during power outages to keep workers safe.
- Preventing voltage or frequency issues in the distribution network.
Your system must be inspected and certified by relevant authorities before activation. Connecting improperly can cause legal problems or delays in getting net metering approval.
Monitoring and Maintenance
Once your system is running, continuous monitoring is crucial. You should regularly check your meter readings and solar panel performance to ensure you are generating energy efficiently and getting correct credits.
Common methods include:
- Using online portals or apps provided by your power company.
- Inspecting panels visually for dirt, shading, or damage.
- Scheduling professional maintenance yearly to clean panels and check wiring.
Good maintenance helps prevent energy loss and extends the life of your system, saving you money on energy costs over time.
Economic and Environmental Benefits
Net metering helps you save money and supports cleaner energy. It also changes how power moves through the national grid.
Reduction in Electricity Bills
With net metering, your solar panels generate electricity you can use at home. When you produce more energy than you need, the extra power is sent to the grid.
You receive credits for this extra energy, which lowers your monthly bill. This means you pay less for electricity, especially during peak hours.
Over time, these savings can cover the cost of your solar panels. Many users in Pakistan see a clear drop in their utility bills soon after starting net metering.
Promotion of Clean Energy
Net metering encourages you to use solar power instead of traditional fuels. Solar energy produces no greenhouse gases or air pollution.
By using renewable energy, you reduce your carbon footprint. This helps lower the impact on the environment and promotes sustainable living.
Pakistan aims to increase its use of clean energy, and net metering plays a key role in this. It makes solar power more affordable and attractive.
Impact on National Grid
When you send extra energy to the grid, you help reduce demand on power plants. This can lower the risk of power outages or load shedding.
The grid also becomes more stable and efficient with distributed solar energy. This benefits not only you but your community.
However, managing energy flow requires proper infrastructure and regulations. Pakistan is working on policies to support this balance for long-term benefits.
Regulatory Framework and Policies
The net metering system in Pakistan is controlled by official rules that determine who manages it, how you get credited for extra energy, and recent changes affecting the sector. You will find clear guidelines from national authorities about how to set up and benefit from net metering.
Key Authorities and Regulations
The National Electric Power Regulatory Authority (NEPRA) is the main body overseeing net metering in Pakistan. NEPRA issued net metering regulations in September 2015, which allow you to produce your own electricity using renewable sources and sell excess power to your local Distribution Company (DISCO).
The Renewable Energy Act of 2006 also supports net metering, making it part of Pakistan’s broader commitment to clean energy. Each DISCO follows NEPRA’s rules but manages the connection and billing with you.
You must register your solar or renewable system with NEPRA and your DISCO to participate legally.
Tariff Structures and Credits
Under Pakistan’s net metering rules, when your system produces more electricity than you use, your DISCO buys the extra units. This is done through a credit system that offsets your future electricity bills.
You pay for net consumption only, which is your use minus the power you supplied to the grid.
Key points on the tariff:
- Excess electricity feeds back to the grid.
- Credits appear as units that reduce your bill.
- Different DISCOs may have slightly different procedures but follow NEPRA guidelines.
This system ensures you save money and encourages solar power production.
Recent Policy Updates
Pakistan has made recent adjustments to net metering to improve the system’s efficiency and fairness. Some changes address limits on system size and tariff rates, which can affect how much you save.
