Electricity systems in Ireland and France most vulnerable to risks this year

On Ireland, the European Network of Transmission System Operators for Electricity said that along with France the electricity system faces what it calls "adequacy risks" through the winter.

The loss of nuclear capacity, mainly in France, but also in Sweden and Finland, is adding stress to the system.

The French and Irish electricity systems are the most vulnerable this winter as Europe is contending with its worst energy crisis in decades.

The continent's network will face the most stress in January and February, but France and Ireland could see issues before that, the European grid group Entsoe said in its preliminary winter outlook.
