one to watch with interest

There is live coverage on the BBC, its quite a story.

Reports suggest that there was a huge dip in demand followed by a cascading failure.

I've long worried about internet enabled devices such as: air conditioners, heat pumps, battery inverters, resistive heaters, washing machines, or other such devices being "hacked" to turn on or off in unison and bringing down the grid. To early to say if this is a deliberate act, it demonstrates what would happen.

About 12GW seems to have been disconnected.

Black-start re-synchronisations required?

Not to downplay the severity and impact of this but I've long had fallback for events like this here in Scotland and at home in Turkey.

We are so wired in these, days to not have a fallback is an oversight I wouldn't ever repeat.

One heck of a sudden loss of load

Portugal are claiming the powercuts were caused by Induced atmospheric vibrations in Spain's 400kV distribution network due to excessive temperature variations.

Ditto!

UPS on the WiFi router and CCTV cameras. A number of USB battery packs and lights. I also have a camping stove and gas bottles handy.

My inverter has UPS output and I have a plan to run a length of conduit down the outside of the wall behind our bed and to the TV. I could even put the A2A on it. However outages are rare where I live, and it is hard to justify spending time and money on something that might never be needed.

Same as you UPS on the Wi-Fi, and usb lights and batteries.
Don’t have battery up and running yet, but have an old inverter generator so all good for 1800watts of emergency power…

Hope it doesn’t affect too many hospitals etc for too long and and they have back ups in place

Quote ..........REN said: “Due to extreme temperature variations in the interior of 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.”
Is this really a thing ?? never heard of it before........................
