The crisis, and the fix

It varies by region and day, but the consistent range reported through spring/early summer 2026 is grim — most areas are getting only a few hours of power in a 24–36 hour window, not the other way around.

As of April 5, 2026, Cuba's grid was generating roughly 1,278 MW against peak demand of about 3,000 MW — a deficit of over 1,700 MW, and millions of Cubans are going without electricity for 18 or more hours per day. In some areas, power cuts have lasted up to 20–22 hours a day. One account from mid-May described family members getting maybe two hours of electricity within a 36-hour timeframe. Havana itself has seen individual outages stretch to 24 consecutive hours. So the honest way to frame it: on a 'normal' bad day right now, most Cubans are getting somewhere between 2 and 6 hours of power a day, and on the worst days — total grid collapses, which have happened multiple times this year — it's zero for 24–36+ hours straight. There isn't a stable 'average' because the grid keeps oscillating between rolling blackouts and total collapses.

Net effect on the average Cuban — this cascades through nearly every basic system:

• Water — Nearly one million Cubans depend on tanker trucks for drinking water, because 84% of pumping equipment requires electricity, so when the grid goes down, so does the water supply.
• Healthcare — Five million residents live with chronic illness, thousands of cancer patients need continuous treatment, and over 32,000 pregnant women rely on functioning hospitals — with women reportedly giving birth in completely dark facilities.
• Food — Refrigeration failures spoil perishable food in a country already dealing with shortages, so people are cooking communal meals outdoors with wood and charcoal, pooling whatever they have left.
• Daily life / economy — Trash collection has stalled (garbage has piled up across Havana and other cities due to fuel shortages for trucks), schools and universities have closed, public transport has been limited, and tourism — a major economic pillar — has collapsed, with foreign arrivals down roughly 58% by mid-June as airlines suspended routes over jet fuel shortages.
• Unrest — This has pushed people into the streets. Protests have broken out in Havana neighborhoods like Lawton, with reports of aggressive police repression against demonstrators.
