Scheduled export electricity exchanges were 22.8 % higher than in the previous year, while imports were 7.4 % higher.

The total volume of energy scheduled through the interconnections reached 34,623 GWh, 14.2 % higher than in 2020.

The total volume of energy scheduled through the interconnections reached 34,623 GWh, 14.2 % higher than in 2020. A total of 16,581 GWh was scheduled for export, 22.8 % more than the previous year, and a total of 18,043 GWh was scheduled for import, 7.4 % more than in 2020. As in the previous year, the net balance is again as an importer, with a value of 1,462 GWh, 55. 7 % less than the previous year.

Annual evolution of scheduled cross-border energy exchanges

In 2021, the net monthly balance of scheduled energy exchanges in the Spanish cross-border connections was as an importer in January and from March to October. In February, December and November, the net balance was as an exporter due to a higher contribution of the energy exchange export programmes to the French system and in the last two months of the year also to the Portuguese system. February was the month that registered the highest level of renewable energy production in the year. In November and December, high prices in France meant a greater contribution from export programmes to the French system, so the net balance was also as an exporter. The maximum net import balance took place in June (1,073 GWh) and the maximum export balance occurred in November (1,322 GWh).
