Quick Answer
If your Spanish electricity bill does not show credits for the solar energy you have been exporting, learn how to check your registration status and get your export tariff active. The optimal configuration depends on your actual consumption, roof orientation, battery needs, and choosing the right export tariff.
Why is your solar export compensation missing?
If you have been exporting surplus energy to the grid but your electricity bill does not show any credits (excedentes), you are not alone. This is the most common post-install issue in Spain.
Until the registration is fully finalised and your utility supplier formally activates export compensation, your exports will be ignored. Here is the exact process to check, verify, and resolve this delay.
The legalisation pipeline: from installation to bill
Understanding the administrative steps is critical to diagnosing where the block is:
- Workmanship Certificate (CIE/Boletín): Your installer must sign off the technical specifications of your system.
- Regional Registration: The installer registers this CIE with the industry department of your autonomous community (e.g., Junta de Andalucía).
- Distributor Notification: The industry department registers the system and notifies your regional grid distributor (e.g., e-distribución).
- Supplier Offer: The distributor notifies your electricity supplier (comercializadora) that a generator is active at your CUPS address. The supplier is legally required to modify your contract to include export compensation within 30 days.
This process typically takes 4 to 12 weeks. If your installer delayed submitting the initial CIE registration, the entire pipeline is frozen.
How to check if your system is registered
To verify if your system is registered, create an account on your distributor’s online portal (e.g., e-distribución in Andalusia).
Under your contract details (Mis Consumos / Expedientes), check if your CUPS is flagged as an “Autoconsumo” point. If it shows as a standard consumption point, the distributor has not received the registration paperwork yet.

What to do if registration is delayed
If you have waited more than 8 weeks, contact your installer and ask for the stamped regional industry registration receipt (justificante de presentación). If they cannot provide it, they have not submitted the paperwork.
If they have submitted it, contact your supplier and confirm that they have received the distributor notification to activate the “compensación de excedentes.”
