RGI Statement Blackout in the Iberian Peninsula

Many were quick, without any evidence, to prematurely attribute the blackout that occurred in the Iberian Peninsula on 28 April 2025 to renewable energy sources (RES). The investigation is still ongoing at both national and EU levels, and it will take time to fully assess what has happened. RGI urges a cautious and fact-based approach to public discussions, as root causes are yet to be determined.

Whatever the causes, it is of paramount importance to continue and even accelerate investment in robust electricity grids, flexibility options, to further integrate growing shares of renewable energy sources.

European TSOs have long developed and operated the world’s most interconnected electricity system, and many Member States, including Spain and Portugal, are increasingly demonstrating the feasibility of operating with high shares of renewables for extended periods. RGI acknowledges the swift and effective response by Red Eléctrica and Redes Energéticas Nacionais (REN) in restoring system operations following the blackout,which generated essential lessons that will increase system security while we transit to a fully decarbonised energy system.
