How to apply for net metering connection?
Introduction
Have you ever considered the possibility of generating your own electricity and selling any surplus back to the grid? Through net metering connection, this is now a reality for many consumers in Pakistan. By installing a green meter along with a solar or wind energy system, you can feed excess energy into the national grid, reducing your electricity bills or even earning money for the energy you provide.
What is Net Metering?
Net metering is a billing mechanism that allows consumers to generate their own electricity from renewable sources, like solar or wind, and feed surplus energy back to the grid. This not only reduces reliance on traditional energy sources but also promotes environmental sustainability.
Benefits of Net Metering Connection
- Reduced Electricity Bills: Offset your costs by selling excess energy.
- Return on Investment: Recover your initial investment in solar or wind systems over time.
- Energy Independence: Reduce dependence on the national grid.
- Job Creation: Increased demand for installation and maintenance creates new jobs.
- Environmental Sustainability: Decrease reliance on fossil fuels and lower greenhouse gas emissions.
- Grid Stability: Reduced demand on the national grid can lead to improved stability.
Steps to Apply for Net Metering Connection
Applying for net metering through LESCO involves several specific steps and requirements. Here’s a detailed guide to the application process.
Step-by-Step Application Process
| Step | Description |
|---|---|
| 1. Active Connection | Ensure you have an active electricity connection with LESCO and a billing history. |
| 2. Solar System Installation | Install a renewable energy system (solar or wind) that exceeds your monthly energy consumption. A system capable of generating more than your average monthly usage is recommended. |
| 3. Prepare Application | After installation, prepare your application according to the guidelines set by NEPRA. You can consult any AEDB-registered solar company for assistance. |
| 4. Submit Application | Submit your application to LESCO, along with necessary documents (like proof of installation, technical details of the system, etc.). |
| 5. Inspection and NOC Issuance | LESCO will conduct an inspection of your premises. If everything meets the required standards, they will issue a No Objection Certificate (NOC). This certificate indicates compliance with all safety and technical regulations. |
| 6. Agreement Signing | After receiving the NOC, you will sign a net metering agreement with LESCO for a duration of three years. |
| 7. Generation License | Your application will be forwarded to the National Electric Power Regulatory Authority (NEPRA) for the issuance of a generation license. This license permits you to produce and sell electricity to the national grid. |
| 8. Connection Charges Estimate | LESCO will provide an estimate for any connection charges related to the installation of the green meter. |
| 9. Payment of Charges | Make the necessary payments as per the estimate provided. |
| 10. Installation of Green Meter | LESCO will install a three-phase green meter at your premises, officially activating your net metering service. |
Requirements for Net Metering
To qualify for net metering, your system must meet specific technical and safety requirements set by NEPRA:
- Initial Requirements:
- NOC by Electrical Inspector: Request a formal inspection from a licensed electrical team to verify compliance with safety and installation standards.
- Single Line Diagram: Provide a schematic diagram of your net metering installation.
- Technical Standards: Ensure that your inverters comply with relevant international standards (e.g., UL 1741, IEEE 1547).
- Mandatory Safety Requirements:
- Your inverter must have an anti-islanding feature to protect against grid failures.
- The interconnection disconnect switch must adhere to IEC and IEEE safety standards.
- Recommended Safety Measures:
- Implement earthing protection.
- Use surge protection devices for voltage spikes.
- Install quality circuit breakers to prevent electrical fires.
Understanding Your LESCO Net Metering Bill
Understanding how your net metering bill is calculated is crucial for managing your energy expenses effectively. Here are key terms to know:
| Term | Description |
|---|---|
| Peak Hours | Typically from 6 PM to 10 PM in summer; higher rates apply. |
| Off-Peak Hours | The remaining hours when rates are lower. |
| Import Units | Units drawn from the grid when your system cannot meet consumption. |
| Export Units | Surplus units fed back into the grid, credited to your account. |
Sample Bill Calculation
To illustrate how your bill is calculated, let’s break down the process into two scenarios: peak and off-peak usage.
Example 1: Peak Hour Bill
- Energy Consumed: 200 units during peak hours
- Rate: Rs. 25/unit
- Total Bill: 200 x 25 = Rs. 5,000
Example 2: Off-Peak Hour Bill
- Energy Generated: 600 units
- Energy Consumed: 200 units
- Energy Exported: 400 units
- Rate for Off-Peak: Rs. 14/unit
| Type | Units | Price Per Unit | Total Price |
|---|---|---|---|
| Import | 200 | 25 | 5,000 |
| Export | 400 | 14 | 5,600 |
Net Bill Calculation
- Peak Hour Bill: Rs. 5,000
- Off-Peak Credit: Rs. 5,600
- Net Bill: 5,000 – 5,600 = Rs. -600 (You receive this amount from LESCO)
Fee Structure for Net Metering
To obtain a generation license, you may be required to pay a fee based on the size of your renewable energy facility:
| Size of Facility (kW) | Fee |
|---|---|
| 0-20 | Free |
| 20-50 | Rs. 500 |
| 50-100 | Rs. 1,000 |
| 100-1,000 | Rs. 5,000 |
Conclusion
LESCO’s net metering program provides an excellent opportunity for consumers to reduce their electricity bills and promote renewable energy. By following the outlined steps and meeting the necessary requirements, you can successfully apply for a green meter and start generating your own electricity.
This not only offers financial benefits but also contributes to a sustainable future. If you have any questions or need assistance with your application, don’t hesitate to contact your local DISCO or an AEDB-registered solar company.
