Thanks @lucia I look forward to some technical facts as well as executive summaries. The foreign reports are not separate investigations just translation from El Pais. Browsing the Spanish press (looking for trade press reports) there was some speculation on the contribution from some form of corruption. Is this something you have any fact on rather than the speculation?

The first press reporting is out Here's a brief synopsis from Spanish media:

The big Blackout El Apagón: 

Yes I realise I'm picking this up a week late...
... but I don't like the way in which the Spanish Minister, Sara Aagesen, has released this to the press.

 

1: There's too much 'apportioning of blame', which isn't helpful.

When a complex situation has resulted in a national outage, you need to encourage feedback from all those involved technically.
Attacking regulatory and technical mistakes by Red Eléctrica, will have the opposite effect.

Who, from a technical background, would now want to work with a Minister who's going to throw the mess all over you when something goes wrong in future?

 

2: Text-based descriptions of power surges and fluctuations are next to useless.

Any such report must be accompanied by timelines showing the relevant data.

Only when the reader sees the periodicity and level of such fluctuations is it possible to appreciate what the Grid Operator could and could not do with the tools they had available to them at the time.

 

3: Whyever does the Spanish Government think there's anything to be gained by issuing a press release in advance of the main technical report.

Any incorrect observations and opinions that have been made by the Minister, are now almost impossible to retract!

Save energy... recycle electrons!
