Cascade failure maybe? Sudden loss causes other plants to try to pick up slack, overloading one of them, which puts even more pressure on the rest until they all fail?
It’s Cuba. They’ve been hamstringed by the US embargo for a very long time. I’m amazed they’re doing as well as they are. My understanding is that, with the exception of medicine and food, basically anything that touches American soil or American hands (literally or metaphorically) is illegal to officially export to Cuba regardless of the country it’s being sold in.
So for an example, any steel made in the US, manufactured for US companies, made using iron from the US, etc, may not be officially sold to Cuba. That doesn’t mean a Mexican company can’t buy the steel and resell it to Cuba; but it means Cuba potentially has to pay multiple tariffs and pay to have it bounced from the US to at least one other country before it can go to Cuba.
Furthermore, my understanding is that foreign companies with a US presence don’t tend to do business with Cuba because the US will put pressure on them to stop doing business with Cuba.
The embargo needs to end. Cuba could have been the US’ strange, goofy cousin with weird ideas about government and economy; because it seems like the Cuban government is making a legitimate attempt at a socialistic system. However, US capitalists ruined everything (iirc the embargo didn’t start with the cold war, it started because Cuba overthrew the banana republic previously ruling them, which pissed off fruit companies. Said companies then cried to Uncle Sam because their slaves revolted and the US said, “you gotta pay them back for all the fruit they lost, plus interest”.)
For a historical analogue check out what happened in Italy on 28. September 2003. One international line in Switzerland sparked to a tree, and got shut down, that caused a cascade where the other lines to France were overheating and getting shut down a few minutes after, and Italy didn’t manage to shed enough load in time to keep up their frequency internally, then everything shut off when it drooped low enough. Took them 18 hours afterwards to get the whole grid back online.
Electric grids are really tough to get back online from what I’ve read. Rolling blackouts help keep things online, but if the whole thing goes down at once it’s tricky to get all the generators on the same timing for their 60/50 Hz transmission lines.
The blackout’s proximate cause was a software bug in the alarm system at the control room of FirstEnergy, which rendered operators unaware of the need to redistribute load after overloaded transmission lines drooped into foliage. What should have been a manageable local blackout cascaded into the collapse of much of the Northeast regional electricity distribution system.
Not a plant but another example of something that should have been small causing massive outages. From what I know talking to people who’ve worked for the province’s grid operator, it’s a massive job to keep everything going.
That’s how power works, you miss your requirements by even a little and you can get cascading failures if you haven’t engineered things well and your guys aren’t sharp.
Power engineering is not something casual, it’s brutal and if you aren’t on your toes then your toes will leave black sooty marks where they were.
We spend insane amounts of money keeping things going, Cuba probably cut corners and couldn’t do upgrades due to sanctions/embargoes.
I don’t get it. How does the failure of one single power plant cripple an island that large?
Here’s Practical Engineering explaining how it almost happened in Texas. he also goes into why starting from a black start is so hard

I’m amazed they don’t have redundancies in case of things like this. I guess not.

That could never happen here.
I would have hoped things had improved in the last 20 years. Apparently they haven’t, at least in Cuba.
I’d be more amazed if they where able to build that capacity behind an American blockade
It’s an embargo, not a blockade. Plenty of other countries trade with Cuba. In fact, Canadians go to Cuban resorts on the regular.

If you keep proactive with rolling blackouts you have a chance, but if you are slacking even a bit all the spinning plates fall at once.
