Hello,
Tesla has recently opened many more superchargers for all VE. While it looks like the site has been updated with the ones for other countries (like France), the information has not been updated for Spain.
Let me mention some sites that are now “widely” accessible in Spain (I might be forgotting some):
- Sant Cugat
- Tarragona
- Cambrils
- Lleida
- Girona
- Valencia (Paterna)
