alojapan.com/1262466/snake-hal Snake halts Japan’s bullet trains after getting tangled in power lines #BulletTrain #Japan #JapanNews #KyodoNews #news #Osaka #PowerOutage #PunctualService #TokaidoShinkansen Japan’s high-speed bullet train services were halted on its busiest line connecting Tokyo and Osaka after a snake became tangled in the overhead wires, causing a power outage. The incident occurred between Gifu-Hashima and Maibara station around 5.25pm on Wednesday, 30 A…

The headline here said:
"Spain, Portugal turn power back on, seek answers after one of Europe's worst outages"
(CBC news, "world" section)
They had a sub-7 hour outage.
I guess their electric grid is a lot better than the North American ones, that occasionally suffer multi-day outages.
Eg, ice storms, electromagnetic storms, excessive demand events (those last in Texas).
So kudos to Spain for quick recovery.

So, how did we, as a family, cope with the #blackout in Granada?

We bought fresh tomatoes and bread with some spare cash, and fished some canned tuna out from the back of the cupboard.

We played board games, and, with the little one, made an old cathode-ray TV out of a cardboard Bauli colomba box, so we could hear some (unicorn!) news. Then we went to bed and read in the dying light until our eyes flickered shut.

LESSON FROM THE POWER OUTAGE

What we learned from the power outage of yesterday in Spain and Portugal is that without hydroelectric and fossil-fuel power stations you can't restart the grid, while nuclear power stations take a long time to restart.

#PowerOutage
But a couple decades ago, I lived outside the city limits on a rural power cooperative with above ground infrastructure and we encountered multiple hour outages every few years. Being also on well water and having a disabled child, our contingencies were: 5 gallon filled water container and a small generator (for some lights, gas furnace fan and ignition and refrigerator).
With our climate crisis and possible deathly heat waves, air conditioning contingency may prove critical. 2/2

#PowerOutage
Reading about the Spain/Portugal widespread and lengthy power outage got me thinking again about contingencies. I live in a city with a large medical center and multiple tech industries, and robust electric power infrastructure. I cannot recall a power outage lasting more than a few minutes in multiple decades. So our contingencies are just battery backups for computer, Wi-Fi, and TV so a 5 minute outage does not even disrupt anything we're doing. 1/x

This very interesting article basically says it was likely to be either human error or a system fault that caused the Iberian apagón or grid shutdown.
Not an excess of wind or solar, not a cyber attack, not a weather abnormality.
However, because of the uneven and rapid expansion of solar and wind, the system relies on quick corrections to rebalance frequency & voltage. Seems likely there was a system fault to do with the rebalancing mechanism.

After 14 hours without electricity in most of Spain, we are now back online in #Granada. Lots of panic here in the city. Some decided to make the most of it and party, some decided to prepare for the worst and look after their closest. Some worried about work and deadlines. Some played cards and admired the stars. Among other things, I helped an elderly neighbour break back into her apartment with an old London Transport Oyster card.

Lots of questions remain ...
