Understanding your unique export identifier
An Export MPAN is a unique 21-digit reference number that identifies an electricity export supply point in the UK. It is a critical identifier for microgenerators, such as those with solar photovoltaic (PV) panels or wind turbines, who wish to sell their excess electricity back to the National Grid. Without an Export MPAN, your energy supplier cannot properly record and pay you for the electricity your system sends out.
The difference between Import and export MPANs
It is easy to confuse an Export MPAN with an Import MPAN, but they serve distinct purposes. Your property already has an Import MPAN, which identifies the point where electricity is supplied to your property from the grid. The Export MPAN, however, specifically identifies the point where electricity is supplied from your property to the grid. Even at the same address, these are separate identifiers for different energy flows.
How the SEG works for microgenerators
The Smart Export Guarantee (SEG) is a UK government-backed scheme introduced in January 2020, replacing the previous Feed-in Tariff (FiT) scheme for new installations. Under the SEG, larger energy suppliers (those with over 150,000 domestic electricity customers) are legally required to offer tariffs that pay customers for the renewable electricity they export to the grid. This means your Export MPAN is essential for participating in the SEG and receiving payments for your surplus energy. Ofgem, the UK's energy regulator, oversees the SEG to ensure suppliers meet their obligations.
Key eligibility requirements for SEG tariffs
To qualify for an SEG tariff, your microgeneration system typically needs to be certified under the Microgeneration Certification Scheme (MCS) or an equivalent scheme. This certification ensures your installation meets specific quality and safety standards. While the SEG mandates that large suppliers offer tariffs, the rates they pay can vary, so it is worth comparing options.
Connecting with your distribution network operator (DNO)
The process of obtaining an Export MPAN begins with your Distribution Network Operator (DNO) . Your DNO is responsible for the local electricity network infrastructure that connects your property to the wider grid.
Here is the step-by-step process:
- Ensure MCS certification: Your microgeneration system must first be certified under the MCS or an equivalent scheme. This is a common prerequisite for both grid connection and SEG eligibility.
- Contact your DNO: Reach out to your DNO to confirm your system's grid connection and to request an Export MPAN. They will process your application and issue the unique number.
You can find your specific DNO using the Energy Networks Association (ENA) postcode lookup tool. This tool will tell you which DNO operates in your area, allowing you to contact the correct organisation.
What to do after receiving your Export MPAN
Once your DNO has issued your Export MPAN, you are one step closer to earning from your exported electricity. This number is a crucial piece of information you will need when applying for an SEG tariff with an energy supplier. Keep it safe, along with your MCS certificate, as both will be required for your SEG application.
Choosing the right SEG supplier
With your Export MPAN in hand, the next step is to choose an energy supplier that offers an SEG tariff. While all large suppliers must offer an SEG, the rates and terms can differ. It is advisable to research and compare the various SEG tariffs available to find one that best suits your needs. Consider factors like payment rates, contract length, and how often payments are made.
The application process: documents and details
Once you have selected a supplier, you will need to complete their SEG application process. This typically involves providing your Export MPAN and a copy of your MCS certificate. The supplier will use your Export MPAN to register your export supply point and ensure that your exported electricity can be accurately measured and paid for.
Smart metering and accurate readings
For accurate payments under the SEG, having a smart meter is highly beneficial. Smart meters automatically send your export readings to your energy supplier, ensuring that you are paid precisely for the electricity you send to the grid. This eliminates the need for manual submissions and helps to avoid estimated payments.
Understanding your SEG payments
Your SEG payments will be based on the amount of electricity you export, as recorded by your meter. Suppliers typically pay per kilowatt-hour (kWh) exported. By understanding your system's generation patterns and your household's consumption, you can optimise your export to maximise your earnings. Fuse Energy provides export statements in the app, helping you keep track of your energy flows and payments.
