France-Spain exchange capacities


Average available capacity on the France-Spain border was 2,546 MW for exports and 2,190 MW for imports.

Capacity availability continues to limit exchanges 75% of the time (62% of the time for exports and 13% for imports).

Since the HVDC Baixas-Santa Llogaia line was commissioned in 2015, saturation of the interconnection has decreased, falling from 87% in 2015 to 70% in 2016 and 75% in 2017.

Improvements are still being made including the introduction of a coordinated capacity calculation in 2019 and, longer term, the Bay of Biscay project, which involves building a new underground and underwater interconnection line to double exchange capacities between France and Spain.

More information about the Bay of Biscay project can be found here.

France still a net exporter


France once again ended the year with a high export balance of 12 TWh, though this was slightly lower than in 2017, reflecting an increase in hydropower generation in the Iberian Peninsula.

France was a net importer on its border with Spain in March, when Spanish wind power generation was particularly high, and in November, when market conditions were less favourable in France.
