MADRID - Spanish grid operator Redeia blamed power plants for the massive blackout that affected the Iberian peninsula in April, as it disputed a government report that said its failure to calculate the correct energy mix was a key factor.
REE-owner Redeia’s own investigation discovered anomalies in the disconnection of power plants on April 28
A combined-cycle plant that was supposed to provide stability to the system disconnected in the first seconds of the blackout when it should not have, while there was also an anomalous growth in demand from the transport network, she said.
“Based on our calculation, there was enough voltage control capabilities planned” by Redeia, she said. “Had conventional power plants done their job in controlling the voltage there would have been no blackout.”
Aelec, which represents Spain’s main electricity companies including Iberdrola and Endesa, said in a statement on June 17 it agreed that voltage control was the main cause of the outage, but said that, as system operator, Redeia was ultimately responsible for controlling voltage.
The government’s report released on June 17
But Ms Sanchez said the system was in “absolutely normal conditions” at noon just before the blackout and that adding another gas plant to the system to absorb additional voltage would have made no difference.
Redeia, which is partly state-owned, will release its own full report on the causes of the outage, its chairperson, Ms Beatriz Corredor, told the same news briefing.
Ms Corredor said she had absolute faith in Redeia’s calculations and that the operator had complied with all procedures and rules. REUTERS
