European energy interconnections ensure stability but face challenges regarding dependency and infrastructure limits during crises.

Following a power outage in Madrid, residents expressed concern about the EU’s emergency kit, drawing parallels to lessons learned from the war in Ukraine regarding potential larger crises behind energy issues. The discussion highlighted the role of interconnected electrical grids across countries, which allow for electricity exchange and are vital for stability, efficiency, and integrating renewables in Europe. These interconnections function as support routes during emergencies, demonstrating energy solidarity. Historical examples show this cooperation, such as assistance from France and Morocco to Spain during a recent blackout. While these systems facilitate necessary support, experts caution that they operate based on immediate needs rather than pre-set reserves. The case of the Balkans showed internal dependency issues requiring coordinated responses. Following past incidents like an Italian blackout, safety protocols have been revised with new monitoring systems. The war in Ukraine has fundamentally changed priorities, making the European grid a crucial lifeline for Ukraine’s energy supply. Despite high EU dependence on imports (around 58% in 2023), experts stress that each country needs diverse local sources and reserves. Current infrastructure limitations are also an issue; for instance, Central Europe faces capacity constraints, while Spain is noted as an “energy island” with limited direct connections to the European mainland, meaning its transmission lines may be too small to handle emergency imports even if offered by neighbors.
