The blackout that left Spain and Portugal in the dark on April 28 was caused by multiple factors, and not by a cyberattack.
Blame is shared between Red Electrica de Espana (REE) and the big private companies.
The report presented explaining the causes of the blackout has significant omissions, with some key entities not mentioned.
The Government had to sign confidentiality contracts to be able to access the companies' data.
The government and major electric companies need to invest in improving the electrical system to prevent similar incidents.
The report also indicates the need to renew the operating regulations in the energy sector.
Conclusion: Clarity and transparency are needed in the electrical sector, especially during times of change and transformation. In addition, avoiding the repetition of incidents like the April 28th blackout is paramount.
