The Comisión Nacional de los Mercados y de la Competencia (CNMC) has published a report outlining recommendations to address voltage instability issues that arose after the nationwide blackout in April 2025. The agency emphasizes the need for increased coordination among network operators and improved visibility of their infrastructure to effectively manage future incidents. Amidst the systemic challenges, the CNMC indicates that existing regulatory tools should be better utilized to ensure reliable electricity supply.

In its recommendations, the CNMC explores the complexities regarding shared evacuation infrastructures utilized by multiple producers, suggesting that these systems significantly contribute to the difficulties faced during power fluctuations. The agency proposes a series of solutions aimed at enhancing the overall stability of the electricity system, focusing on collaborative measures among stakeholders involved in power distribution and network management.

Additionally, the CNMC highlights the importance of preparing for future incidents by reinforcing existing regulatory frameworks. The recommendations reflect a proactive approach to addressing both immediate concerns stemming from the blackout and long-term strategies that can prevent similar occurrences in the future, ensuring a more resilient energy framework for Spain.
