“induced atmospheric vibration” on 400KV lines is the current theory

-> Power outage -> Wild guess that Russia has been doing it, 0 proof or even hint -> "This is a war of agression, we should respond" Are you suggesting to attack Russia, based on absolute thin air?

> thin air

Except for the mountain of evil, violent, underhanded and illegal stuff Russia keeps getting caught doing, and has so far escaped scot-free due to Western cowardice?

Sounds like an incredibly expensive solution to a problem that could be tackled more efficiently at a larger scale.

Didn't we used to pump steam around for heating and now homes have individual furnaces? If the cost for this were about the cost of a furnace I don't see why this wouldn't be viable. I bought a generator for just this situation.

In Polish cities there are attempts to move in exact opposite way (close individual furnaces) due to rampant pollution during winter (1000% of PM 2.5 norm level of pollution happening occasionally, over 400% PM2.5 norm lasting for weeks etc)

Call me crazy but I'd love to see full power outage at least once in my life

I used to live in an area that regularly had power outages during thunderstorms. I was also once in London during a power cut that took out most of the city centre. It was a strange experience, but not as weird as walking through empty streets in the time of covid.

Maybe just my perception, but power outages seem to be getting rarer with time, though when they do happen they seem to be far larger.

Europe still has many megawatts of solar with inverters that disconnect when detecting any grid disruption. This is the absolute worst thing to do when there is a shortage of power - you immediately make the shortage worse and more grid disconnects. The real fix is a grid with second by second pricing based on system frequency, and every individual user allowed to set a daily 'spend cap' of euros/dollars, letting the…

This is the exact kind of techbro nonsense that I’ve come to expect from this website. No empathy for your fellow humans and dressed with a side of “computers and code plus finance”.

I thank the heavens that the people who run the electricity system do not share your opinions.

I saw it on twitter and had to go to BBC to make sure this isn't some joke or hoax. 2025 and we have National level power cuts? I know it may be rare but I think some day we really need to move or mandate every single flat / home / apartment / living places to have a 12 - 24 hours backup battery included. Something that has 10K+ Cycles, durable and non-flammable. Not only does it make sure our modern lives without su…

Something that stores enough energy to bake cookies will always somehow be flammable.

Gravity storage of water. Not flammable, but could definitely bake cookies.

I'm going with AGI awakening in some lab today.

A few months ago I was hit by a blackout literally the second I was about to start delivering a company-wide talk on AI. Everything went out - Internet, mobile networks, street lighting, the lot.

We're a remote business so it seemed like I'd just rudely dropped off the call, but as everything was down I couldn't let people know what'd happened.

Apparently it was caused by botched maintenance work affecting 30,000 houses, but the timing was so perfect I can't help thinking it was because our AGI overlords really didn't want me to deliver that talk for some reason.

A fire in the south-west of France, which damaged a high-voltage power line has also been identified as a possible cause: https://www.euronews.com/my-europe/2025/04/28/spain-portugal...

Surely there is more than 0 redundancy so that one power line failure would never result in this level of catastrophe.

Redundant systems have failures in one path quite often that you never know anything about. We get headlines when the failures correlate in the same timeslot.

> Is a grid built on renewables and batteries somehow more resilient? So this is a complicated subject in itself, and a full answer won't fit inside this textbox. Some bullet points: - Grid stability is maintained by batteries, but not literally. The "batteries" in question are typically rotating generators, i.e. turbines, wind, literally anything where you have an electrical coupling to a lot of physical inertia. Th…

For wind turbines, solar, and batteries, the frequency stability is doable through controlling frequency from inverters. Some wind turbines are also internally a hybrid design that can dynamically adjust the frequency difference angle both for minimal losses in production, but also to provide frequency shifting and even artificial demand (i.e. essentially using wind power as brake)

The inertia provided by synchronous generators was in essence a natural benefit to the grid that we never appreciated previously. But now with more renewables it’s now something we have to consider and design for. Running a grid on 100% non synchronous requires a bit more effort!
