What’s Going On with Cuba’s Blackouts — And What Travellers Should Know About the Cuba Blackout:
Recently, Cuba has experienced several nationwide blackouts—with the grid collapsing in multiple incidents over the past months. (Reuters) These are serious disruptions, but they aren’t a reason to cancel your trip. With good preparation and knowing what to expect, you can still enjoy a smooth, safe, memorable vacation. Here’s a breakdown of what’s behind the outages, what the current situation looks like, and useful tips for travellers.
This information is crucial for understanding the current Cuba blackout situation.
What Caused the Blackouts
The causes are complex and reflect long-standing challenges. Key contributing factors include:
- Aging infrastructure: Many of Cuba’s thermo-electric power plants and electricity transmission lines are old and haven’t always had full maintenance or upgrades. (Wikipedia)
- Fuel shortages: Cuba relies heavily on imported fuel to run its power plants. Delays or reductions in fuel shipments (from allies like Venezuela, Russia, Mexico) strain the system. (Reuters)
- High demand and overloading: Peak usage, especially with more air-conditioning, adds pressure. In many parts of the country, daily blackouts (rolling or scheduled) were already common before full grid collapses. (Al Jazeera)
- Single major failures triggering chain reactions: For example, malfunctions or failures at large power plants or substations (e.g. CTE Guiteras; a substation in Havana) have precipitated the full grid shutdowns. (Reuters)
So while the blackouts are real and inconvenient, they’re the result of infrastructure and supply problems—not a sudden breakdown of basic safety or security.
What’s the Situation Like Now
Here’s what travellers should be aware of, based on latest reports:
- The blackout of 10 September 2025 was the fourth nationwide collapse of the grid in under a year. (Reuters)
- Restoration of power is underway in most areas, often first targeting Havana and major populated or critical zones. (Reuters)
- Essential services — hospitals, water pumping stations, airports — are generally maintained via backup systems and generators. (Reuters)
What Travellers Should Expect — And How to Prepare
Knowing what to expect can make the difference. Travellers often report that, despite the outages, hotels, tourist facilities, and amenities are still functional. Here’s how to manage expectations, what to pack, and what to check before you travel.
What to Expect at Your Destination
- Hotels, resorts, and well-established tourist restaurants usually have generators and backup power systems. These are in place to allow uninterrupted service: lights, air-conditioning, refrigeration, elevators, and often Wi-Fi. So while local neighborhoods may suffer, your accommodation likely won’t be plunged into darkness. (Past reports explicitly noted that some hotels remained lit when surrounding areas did not. ) (Reuters)
- Services like safe drinking water, food preparation, and hotel amenities are generally maintained in tourist zones. Food in hotels and restaurants is preserved thanks to generators. You may notice slight delays or fluctuations, but your basic needs should be covered.
- Internet/mobile service may be more patchy outside tourist zones or during severe outages. Be ready for reduced connectivity in remote areas.
Packing & Preparations
Here are things you can do ahead of and during your trip to stay comfortable and safe:
| What to Bring | Why It Helps |
| Portable power bank / solar charger | To charge phones, tablets when electricity is not reliable. |
| Flashlight or headlamp (small LED) | Fast and easy light source for evenings or power dips. |
| Extra batteries / rechargeable items | For devices that rely on them ( e.g. camera, portable fan). |
| Snacks and bottled water | Just in case local shops are delayed; being prepared reduces stress when you are staying out of a resort. |
| Light clothing, especially for evenings | Without AC, interiors may be warmer. |
| Copies of hotel address/contact and print-outs of bookings | If internet is out, having printed backups helps. |
Things to Do Before & During Travel
- Check with your hotel: Before booking or shortly before arriving, ask what their backup power situation is. A good hotel will openly let you know if they have generators/backups and how many hours of outage they can handle.
- Travel insurance: Make sure your insurance covers disruptions. It may include compensation or help if your plans (transport, tours) are affected.
- Flexible plans: Have a few backup ideas for things to do indoors (museums, spas, reading, etc.) for days when the outside temperature might be uncomfortable.
- Keep essentials with you: Especially medications, chargers, cash (since electronic payments may have temporary disruptions).
- Stay informed: Monitor local news (hotel staff can be very helpful), follow the advice of local authorities, and allow extra time for transport or excursions in case of delays.
Should It Affect Your Travel Plans?
Short answer: no, not necessarily. For most travelers, especially those staying at established tourist hotels or resorts, the impact should be minimal. These places are designed to cope with these challenges, and staff are used to them. The essential services are kept running, and many facilities still offer a high level of comfort.
If you are planning to travel more off the beaten path, or to very remote or rural areas, then the risk is greater of facing more frequent or longer outages. But with awareness and preparation, these can be managed without turning them into a crisis.
Final Thoughts
Cuba’s recent blackouts are a real issue—rooted in infrastructure challenges, fuel supply, and an aging power system. But they are not a sign that tourism has to suffer. Hotels, restaurants, resorts, and other tourist-focused facilities are among the places that are best prepared for power outages. If you come with the right expectations and a little extra backup, your trip can go very smoothly.
So pack your power bank, choose a hotel with backup systems, build a flexible itinerary — and get ready to enjoy the vibrant culture, beautiful landscapes, friendly people, and rhythm of Cuba. A few extra precautions will help ensure your visit is memorable for all the right reasons.
