Ja absolut så var det flera orsaker i samband som orsakade avbrottet men rotorsaken var ett ostabilt system med otillräckligt med stabil kraft att balansera med.
Så viktigt att ha mer förbränningsbaserad elproduktion i Spaniens elsystem framöver.
While several factors played a role that day, Aagesen confirmed that the ultimate cause was a surge in voltage that the grid was unable to absorb. It triggered a cascade of disconnections of generation.
Voltage surges can be caused by multiple factors ranging from lightning strikes, faulty equipment, or grid instability. The probe pointed to grid instability earlier that morning.
REE, which is partly state-owned, did not have enough thermal power stations switched on when the voltage surge caused a chain reaction leading to the power outage, Aagesen said.
The government said on Tuesday it would propose measures to strengthen the grid and improve its ability to control voltage in the system. It would also push to further integrate the peninsula with the European grid, it said.
Pratheeksha Ramdas, Senior New Energies Analyst and Iberia power market expert at Rystad Energy said the incident highlighted the essential role thermal power plants, especially gas-fired plants continued to play.
