Resumen divulgativo:
Esta presentación resume la investigación llevada a cabo por un equipo dirigido por el autor a petición de Endesa e Iberdrola (las dos mayores empresas eléctricas españolas), en la que se examinan los hechos y circunstancias que provocaron el apagón en el sistema ibérico el 28 de abril de 2025. Aunque la investigación aborda todos los hechos y circunstancias que provocaron el apagón, esta presentación tiene como objetivo llamar la atención del público sobre nuevos análisis que ofrecen respuestas bien fundamentadas a cuestiones sin resolver derivadas de un estudio minucioso de los informes publicados.
