A major power outage that paralyzed the Iberian Peninsula in April was caused by "overvoltage" on the grid that triggered "a chain reaction," according to a government report released Tuesday.

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.

      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”
