Net metering in pakistan
Net metering, a revolutionary concept in the field of renewable energy, allows homeowners and businesses to generate their electricity using solar power and receive credits for any surplus energy sent back to the grid. This practice not only reduces electricity bills but can also potentially result in financial gains, transforming the way we interact with power utilities. Known as “Green Meter” in some circles, net metering is a growing trend in Pakistan, with over 23,000 households currently utilizing this facility.
What is Net Metering?
Net metering is a billing mechanism that uses a digital device, known as a net meter, to track the amount of surplus solar energy produced by your solar panels. When your solar system generates more electricity than you need, the excess energy is sent back to the national grid. This process results in a reduction of your electricity bill as credits are applied for the energy you provide to the grid. Conversely, when your solar panels are not generating enough power, such as at night, you can draw energy from the grid and pay for it as usual.
Example of Net Metering in Action
Consider a scenario where you own a shop with solar panels installed. If these panels produce more electricity than the shop consumes, the net meter will run backward as the surplus energy flows back to the grid. This surplus can reduce your electricity bill or even result in a payment from the power utility, WAPDA. If you use more grid electricity than you export during times when solar panels are not active, you’ll receive a bill for the net amount. However, if your surplus exceeds your usage, the credit can offset your energy costs or be paid out to you.
Net Metering Tariffs in Pakistan
The financial aspect of net metering is regulated by the National Electric Power Regulatory Authority (NEPRA). The current tariff for net metering in Pakistan is approximately Rs. 19.32 per kilowatt-hour (kWh). This rate reflects the compensation provided for the electricity sent back to the grid. It’s essential to understand that the rates vary between peak and off-peak hours.
- Peak Hours: Typically from 5 PM to 10 PM, these are periods of high electricity demand and thus higher rates.
- Off-Peak Hours: These include late-night and early-morning hours when electricity demand is lower and rates are reduced.
For instance, if a 4 kW solar system produces 500 units of electricity monthly, with 200 units exported to the grid and 50 units purchased from the grid, your bill would be calculated based on these tariffs. If your solar system generates more during off-peak hours and you buy more during peak hours, the difference could result in a credit or a debit on your bill.
Net Metering Users and Trends
As of June 2023, approximately 66% of net-metered electricity in Pakistan was contributed by domestic and small-scale users, with this percentage expected to rise by mid-2024. This growing adoption reflects a significant shift towards solar energy as a means to manage energy costs and earn from surplus power generation.
Installation and Eligibility
To benefit from net metering, certain criteria must be met. These include:
- Consumer Category: Must align with the types eligible for net metering.
- Solar PV System Capacity: Must meet the minimum requirements set by NEPRA.
- Voltage Supply Level: This should match the standards for grid connection.
The Net Metering Process
- Installation: A compliant solar system must be installed by a certified provider.
- Application: Prepare and apply as per SRO 892 (1) 2015.
- Inspection: An inspection by the Energy Department ensures compliance with technical standards.
- Agreement: Sign a three-year agreement with the distributor.
- Generation License: Obtain a license from NEPRA.
- Activation: Once approved, your net meter will be activated, enabling the crediting process.
Advantages of Net Metering
Net metering offers several benefits:
- Cost Efficiency: Reduces electricity bills by offsetting the cost with credits for surplus energy.
- Control Over Billing: Provides transparency and control over your electricity consumption and billing.
- Environmental Impact: Supports renewable energy use, reducing reliance on fossil fuels and lowering greenhouse gas emissions.
- Energy Independence: Encourages self-sufficiency in power generation, enhancing energy security.
Financial Considerations
Investing in a net metering system involves initial setup costs, including purchasing and installing solar panels and the net meter. However, the long-term savings on electricity bills and potential earnings from surplus energy can offer a significant return on investment. The cost varies depending on system size and user category, with residential systems generally being less expensive than commercial or industrial installations.
Environmental Impact
Net metering plays a crucial role in promoting environmental sustainability by:
- Reducing Greenhouse Gas Emissions: By generating clean energy from solar power, it lowers CO2 and other harmful emissions.
- Decreasing Fossil Fuel Dependency: Less reliance on non-renewable energy sources helps conserve resources and minimize environmental damage.
- Supporting National Sustainability Goals: Contributes to Pakistan’s renewable energy targets and overall environmental conservation efforts.
