On April 2025, Spain and much of Portugal experienced a massive blackout, marking Europe's first 'system black' event in recent memory. Initial media reports suggested that renewable energy sources were to blame, but investigations by the pan-European grid operator ENTSO-E found that governance failures related to voltage management were the true culprits. Despite concerns that this incident might hinder Spain's renewable energy transition, the opposite has occurred. In 2025, Spain added 13.8 gigawatts of solar capacity, a significant increase from 12.3 gigawatts in 2024, demonstrating a solid commitment to replacing fossil fuels with sustainable alternatives. The blackout also led to regulatory changes that now allow renewable technologies to provide voltage control, a critical function previously limited to fossil fuel plants. As a result, Spain's electricity prices have remained among the lowest in Europe, with an average of €43 per MWh in March 2026, significantly lower than prices in Germany and Italy. Analysts emphasize that the ongoing energy crisis has reinforced the importance of renewable energy in stabilizing prices and protecting consumers from volatile gas markets.
