According to the Liberty Times, Cuba's grid collapsed nationwide as major plants tripped in succession, cutting power to roughly ten million people.

Cuba has suffered rolling outages for years amid decrepit thermal plants and chronic fuel scarcity, with repeated national blackouts.

The outage halts refrigeration, medical services and communications at once; in the heat, lost cooling and food storage deepen hardship.

Authorities began restarting plants and phasing power back, but aging equipment and scarce parts and fuel make the pace hard to guarantee.

Analysts add that the entwined economic and energy crises are intensifying emigration pressure.

The Caribbean's energy woes show how fragile infrastructure in small states can cascade when climate and economic shocks hit.
