Cuba faces blackouts amid oil squeeze

Cuba’s power crisis is not one bad day on the grid. It’s a fuel problem, a machinery problem, and a financing problem stacked on top of each other. That’s why the blackouts keep coming back even when one plant returns or one shipment gets through. In early May, officials were still forecasting giant gaps between available electricity and peak demand, which meant outages across the island were basically baked in. ### Why are the blackouts so bad right now? Because Cuba is trying to run an old, fragile power system without enough fuel. On May 3, the state utility forecast just 1,760 megawatts of available generation for the evening peak, against demand of 3,200 megawatts. That left a deficit of 1,440 megawatts and an expected service impact of 1,470 megawatts — in plain English, huge chunks of the country losing power at once.

Cuba’s thermal units are old and maintenance-heavy, and officials have spent the past year trying to bring some of them back while also reviving distributed generation. The government says it recovered more than 1,000 MW of distributed generation in 2025, repaired key thermoelectric units, and raised renewables’ share of the mix from 3% to 10% in a year. That helps, but it still doesn’t solve the basic fuel squeeze. (granma.cu) ### Where did the fuel squeeze come from? Havana says the turning point came at the end of January, when U.S. measures sharply constrained oil deliveries to the island. Cuba’s energy minister said the last ship before a later Russian delivery entered on December 8, and that after January 29 the country’s ability to buy fuel was choked off by tariff pressure and the U.S. military presence in the Caribbean. U.N. experts and U.N. officials have also tied the worsening humanitarian situation to Washington’s moves to block oil supplies. (granma.cu) ### Why does one fuel shortage wreck so much? Because electricity in Cuba is the bottleneck for almost everything else. The U.N. says the energy shock has paralyzed essential services, worsened since late March, and left about 1 million people dependent on water trucking that is itself constrained by diesel shortages. Health care has been hit too — with more than 96,000 pending surgeries, including 11,000 for children. When the grid fails, this is not just about lights going out. (granma.cu) It’s water, transport, refrigeration, clinics, and communications. ### So what is Cuba doing in the short term? The immediate move is triage. Fuel gets steered toward essential services, and the state tries to protect the most critical sites first. That’s where the China-donated solar systems come in. Cuba’s utility is installing 5,000 small photovoltaic systems, including 2,671 earmarked for vital municipal centers like polyclinics, maternity homes, nursing homes, funeral homes, bank branches, radio stations, and telecom facilities. (news.un.org) These systems are not meant to power whole towns — they’re more like backup lungs for the places the state cannot let go dark. ### Will solar parks fix the grid soon? Not soon enough to end today’s outages. Small solar backups can keep emergency rooms, vaccines, and communications running during cuts, but they do not replace the missing bulk generation needed for the national grid. The broader government strategy is to add storage, expand gas use, and keep pushing renewables so Cuba depends less on imported fuel over time. That’s a real structural shift — but it’s a medium-term answer to an immediate crisis. (en.granma.cu) ### Why does this matter beyond Cuba? Because the blackout story is really a stress test of how sanctions, fuel logistics, and aging infrastructure collide. Cuba is showing what happens when an import-dependent grid loses its cushion. The political fight is over blame, but the practical reality is simpler: when fuel stops, everything downstream starts to fail. (granma.cu) ### Bottom line Cuba’s blackouts are no longer a temporary disruption. They are the visible symptom of an energy system operating without enough fuel, with too little redundancy, and under rising humanitarian strain. Solar can protect the edges. It cannot yet carry the center. (granma.cu) (usnews.com)
