Cuba's power grid collapse leaves millions without electricity amid ongoing fuel shortages

On September 18, 2026, Cuba's electrical grid collapsed, leaving millions without power. The Ministry of Energy and Mines reported that the failure was due to issues in high-voltage transmission lines and fuel shortages caused by a U.S. energy blockade. By evening, only a small percentage of users in Havana had their power restored, while residents continued to endure long outages, affecting daily life and essential services.
