Cuba's electrical grid collapsed again on Sunday, the fourth such failure in 48 hours as a looming hurricane threatened to wreak further havoc on the island's decrepit infrastructure. Cuba earlier on Sunday had said it was making headway restoring service after multiple false starts,

Cuba's power grid has ground to a halt for a second time in as many days, leaving 10 million on the island without power and the Caribbean island in a growing sense of crisis.

Cuba's national grid collapsed on Friday, leaving the entire population of 10 million people without electricity and underscoring the precarious state of the Communist-run country's infrastructure and economy.

WHY DID THE GRID COLLAPSE? Cuba's electrical grid and oil-fired power plants are obsolete and crumbling, constructed decades ago and scarcely maintained. And because Cuba produces very little fossil fuel of its own - with limited refining capacity - it depends almost entirely on imports to assure adequate generation.

Cuba’s electrical grid went down Friday after one of the island’s major power plants failed, a day after a massive blackout swept across the Caribbean island and with no official estimate for when service will be restored.

As electricity was being restored in parts of Cuba following an island-wide blackout, a total collapse of the electrical grid occurred once again.
