France was once again a net exporter to Great Britain in 2019. Its balance for the year of 11.3 TWh was lower than in 2018, notably because capacity was limited between April and June due to maintenance on the IFA interconnection with England. Capacity was reduced by as much as 1,000 MW, to about half the normal level, throughout almost all of April.

The interconnector was once again used for exports a large majority of the time. However, France was a net importer from Great Britain when temperatures were low in France and during the heatwave late in July. Over 2019 as a whole, France was a net importer for 860 one-hour periods, or about 10% of the time.
