Boy, did this not age well
That's a good achievement but energy grids have varying degrees of robustness. So a number of days later the grid went down, Spain and Portugal blackouts were making global headlines. The cause - TLRD version it seems like a cascade shut down all the interconnected power networks. From [1]

The Portuguese prime minister, Luís Montenegro, said that the issue originated in Spain. Portugal’s REN said a “rare atmospheric phenomenon” had caused a severe imbalance in temperatures that led to the widespread shutdowns.
REN said: “Due to extreme temperature variations in the interior or Spain, there were anomalous oscillations in the very high voltage lines (400 kV), a phenomenon known as ‘induced atmospheric vibration’. These oscillations caused synchronisation failures between the electrical systems, leading to successive disturbances across the interconnected European network.”
