One year has passed since the blackout and there is still no clear culprit
A year after the great electricity blackout that left millions of people in Spain and Portugal without electricity, a clear person responsible has still not been identified. Neither the Government, nor the European experts from Entso-E nor the CNMC have been able to point to a single cause of the incident.
The various reports agree that it was a multifactorial problem, with episodes of overvoltage, oscillations in the system and disconnections of power plants. They also describe it as an unprecedented event in recent decades and recommend improving the supervision, coordination and regulation of the electrical system.
The CNMC, although it does not assign direct blame, does recognize that there were sufficient tools to have avoided the blackout. In addition, it has opened more than 50 sanctioning files against Red Eléctrica and several large energy companies, which points to possible responsibilities that could be resolved in court.
Meanwhile, the political investigative commissions have not clarified what happened either and have led to a crossroads of accusations. The blackout has also caused a change in the management of the electrical system, increasing adjustment costs, especially due to the use of gas, which is having an impact on the electricity bill.
