Energy Law Spain – Market Entry and Comercializadora Setup
I guide German energy companies into the Spanish electricity market. From the company, through the CNMC registration, to taking part in OMIE.
Spain uses about 250 TWh a year and has a lot of renewable generation. Since the market opened in 1997 (Ley 54/1997), a foreign company can set up its own Comercializadora or buy an existing supplier.
I sit in Málaga and stay with the entry from there. In German, with tax advisors, lawyers, and people who know the CNMC.

Cross-Border DE ↔ ES
Physical deliveries from Germany to Spain run via the French grid bridge. The Spanish-French cross-border capacity (Interconexión) is auctioned daily and continuously via JAO. Pure financial balancing without physical delivery is possible through OMIP contracts and virtual PPAs. I structure the contracts across the border. That includes EEG guarantees of origin, GO certificates, and the Spanish garantías de origen.
