Nobody expects the Spanish interruption

This week Iberian Peninsula had a massive power outage that darkened large parts of Spain and Portugal, affected Andorra, France and according to some, Netherlands and Belgium. I have not yet seen the proximal cause for the outage published, though speculations have run from Russian hackers to atmospheric phenomena. What is increasingly clear is that the Western European power grid has become extremely vulnerable to disturbances and even the slightest wobble can collapse the interconnect.

European power grid is at 50 Hz and already 0.5 Hz out of sync causes massive troubles – the power grid can choose to shut down or experience massive damage when the system goes off even that slightly. In Spain, the power grid began to experience fluctuations blamed at some point on ‘induced atmospheric oscillations’ (a mistranslation?) or anomalous heating. However, the power grid had lost large fraction of its buffering capacity as the power production has moved from traditional big power stations with big turbines that maintain inertia against minor fluctuations to renewable energy which uses inverters. In other words, the power grid had become more fragile. Spain had just six days earlier boasted about having produced 100% of its daily energy by renewables. Spain is not alone with its fragile grid, the EU wide race to Net Zero has weakened grids over the Western continent. Individual countries have relied on power production of their neighbors to subsidize their climate programs, and when the neighboring countries transform from help to drain, whole Western Europe is in trouble,

Snake

Unrelated to European problems, Japanese Tokaido Shinkansen line had about an hour and half train stoppage due to a power outage caused by a snake that had slithered into power line. Or maybe the snake was a tool of a global conspiracy against power grids. The article did not know the fate of the snake.
