France’s export balance with Italy remained high at 18.8 TWh, unchanged from 2018. The interconnection was mostly used for exports: there were only 247 one-hour periods with net imports (less than 3% of the time), down from 330 in 2018.

The upcoming commissioning of the new Savoy-Piedmont interconnection will help boost exchange capacities and opportunities for mutual electricity assistance between France and Italy.

Italy caps imports on days when demand is low, especially weekends in the spring and summer, as it must keep in service enough thermal power plants that can adjust their output to ensure the stability of the power system. On days when solar seems likely to cover a large share of demand, import capacity at interconnections is reduced.
