Spain Says Power Grid Management Mistakes Caused April Blackout.

The article focuses on the causes of a nationwide blackout in Spain that occurred in April, which left over 50 million people without electricity. The Spanish government attributed the outage to planning mistakes by the grid operator, Red Electrica, and insufficient backup power from thermal plants during peak hours. Environmental Transition Minister Sara Aagesen explained that the grid's inability to manage voltage surges was due to the operator's decision not to replace a non-operational thermal plant and the failure of several generation plants to meet their power supply obligations. The government also noted unusual frequency changes in the European grid prior to the blackout but dismissed claims that excessive renewable energy generation was to blame.
