Aagesen singled out the role of the Spanish grid operator REE and certain energy companies she did not name which disconnected their plants “inappropriately… to protect their installations.”

She also pointed to “insufficient voltage control capacity” on the system that day, due in part to a programming flaw, stressing that Spain’s grid is theoretically robust enough to handle such situations.

Due to these misjudgments “we reached a point of no return with an uncontrollable chain reaction” that could only have been managed if steps had been taken beforehand to absorb the overvoltage problems, she added.

I thought this was already known, because of all their solar

That is just right-wing disinformation:

The right-wing opposition has questioned the Socialist-led coalition government’s phase-out of nuclear energy and reliance on renewables, saying they made Spain more vulnerable to blackouts.

But the government says there is no evidence to suggest “an excess of renewables or the lack of nuclear power plants” caused the crisis.

Human error not “faulty renewables”

Ah yes, solar power, known for causing programming flaws

Yeah right. All the solar cells just hacking into the repo, manupulating stuff

Considering just recently a bunch of chinese PV converters have been found to contain extra parts not in the schematics and can be made to create overvoltage remotely, without leaving evidence, I wouldn’t dismiss the possibility outright.

I mean, it wouldn’t have caused the failed voltage regulation itself, but it is realistically possible the initial cause of overvoltage was a hack.

Hard to rule out any possibility if we are just guessing and not requiring proof.

No, the overvoltage. The grid did not manage to handle the issue due to a programming flaw.

Right, also they were all vaxxed against the rona!!! /s

I just hope they demand economical reparations to those un-named energy companies, accordingly to the damage inflicted and not only a few million euros.

Who could have thought that private grid operators would prioritize their installations over anything else.
