Cuba's grid goes offline with blackout after a major power plant fails

Current outage and grid infrastructure

• Commenters note updates that power is being restored in parts of Cuba; airports reportedly operated normally.
• Grid infrastructure is described as old and poorly maintained, with long lead times (≈18+ months) to add new capacity.
• Some expect the situation to remain bad for a long time and foresee potential political consequences, though the likelihood of regime change is debated.

Solar power and alternative energy

• Several ask why a sunny island like Cuba hasn’t gone big on rooftop or utility-scale solar.
• Explanations given: weak investment framework, semi-communist system hostile to foreign capital, poor grid readiness for distributed generation, and lack of financing.
• One thread discusses PV efficiency losses at higher temperatures and the economics of solar parks, with mild disagreement on how limiting heat really is.
• Others point to hurricanes, lack of money, and unpaid debts to Chinese suppliers as barriers.
• Ideas such as Chinese power barges, US nuclear carriers, or large battery farms (e.g., Megapacks) are raised, mostly as thought experiments rather than realistic options.

Sanctions, trade, and external actors

• A major thread debates the impact of decades-long US sanctions, described by some as “economic warfare” opposed by most countries at the UN.
• Others argue Cuba can and does trade with many countries (EU, Canada, China, Venezuela), so sanctions alone cannot explain the crisis.
• Counterpoint: US law threatens secondary sanctions, which can chill third-country trade; some jurisdictions respond with “blocking statutes.”
• Extracts from reporting on China–Cuba relations highlight: shrinking trade, unpaid Cuban debts, minimal Chinese investment compared to the rest of Latin America, and Chinese frustration at Havana’s refusal to adopt market reforms.

Economic model, collapse, and tourism

• Multiple commenters argue Cuba’s centrally planned, Soviet-style economy is fundamentally inefficient and a bigger problem than the embargo.
• Others stress that sanctions crippled key earners like tourism (especially US visitors) and exacerbated an already fragile system.
• Tourism and sugar are seen as Cuba’s main foreign-exchange sources, with tourism badly hit post‑COVID and by US policy reversals.
• Comparisons are made to Haiti, the Dominican Republic, and ex-communist Poland to discuss what small economies “can offer” and how alliances or market reforms can change outcomes.

Geopolitics and ideology

• Some suggest the US should seize the moment to provide infrastructure aid and normalize relations; others insist it’s not in US strategic interest to help a Russian-aligned regime.
• Historical grievances (Cuban Missile Crisis, expropriated US assets, Cuban exile politics in Florida) are invoked to explain why sanctions persist.
• Ideological debate is sharp: some blame “communism” or hardline socialism for predictable shortages and blackouts; others counter that sanctions are designed precisely to ensure such failure and then be cited as proof.
