Why is Cuba having so many power cuts in 2026?: US EO 14380 imposed secondary sanctions on fuel suppliers, cutting imports. The grid generates less than half of peak demand, causing 12+ hour blackouts.Source: UNE / US Treasury
What is EO 14380 and how does it affect Cuba?: EO 14380, signed 29 January 2026, declared a national emergency over Cuba and authorised secondary tariffs on any country selling fuel to Cuba.Source: White House / UN Special Rapporteurs
How many Cuban prisoners were released in the 2026 talks?: The Cuban government stated more than 2,000 prisoners freed by 3 April 2026, though monitors confirmed no political prisoners were included.Source: Díaz-Canel / OCDH
Is Russia still supplying oil to Cuba in 2026?: Yes. A Russian tanker docked in Havana on 31 March 2026 with roughly 730,000 barrels; a second vessel was being loaded.Source: Russian Energy Ministry
Is Cuba's electricity situation improving in April 2026?: Partially. The grid deficit fell from 1,732 MW on 15 April to a forecast 1,365-1,395 MW by 26 April after the Camilo Cienfuegos refinery restarted. However, improvements are concentrated in Havana; eastern provinces absorbed 24-hour daily outages over the same period.Source: Cuba Dispatch
Did Cuba release any political prisoners in its 2026 amnesties?: No. Amnesty International, OCDH, and Prisoners Defenders all verified that neither the 51-prisoner pardon (13 March) nor the 2,010-prisoner pardon (2 April) included any prisoners of conscience. Cuba's penal code explicitly excludes 'crimes against authority' — the category used to prosecute dissidents — from pardons.Source: Amnesty International / OCDH
What is OFAC General Licence 134B and why does Cuba benefit?: GL 134B, issued 18 April 2026, extends cover for Russian crude transactions loaded before 17 April through 16 May. It covers the Sovcomflot tanker Universal bound for Matanzas, allowing Cuba to continue receiving Russian oil under a temporary OFAC window.Source: OFAC
What happened at the US-Cuba Havana talks in April 2026?: A US State Department aircraft made the first US government landing in Havana since 2016 on 10 April 2026. Under-director Garcia del Toro confirmed the talks publicly on 21 April as 'respectful and professional'. A two-week dissident-release deadline set during the talks lapsed on 24 April with zero releases.Source: Cuba Dispatch
How does Cuba's central grid prioritise electricity during blackouts?: Cuba's grid dispatches centrally from large thermal plants and protects the capital's load profile when fuel is rationed. Eastern provinces — Holguín, Granma, Santiago de Cuba — absorb the deficit first, sustaining 24-hour outages while Havana runs blackout-free.Source: Cuba Dispatch
Why did Cuba's national grid fragment on 14 May 2026?: The Antonio Guiteras thermoelectric plant suffered a boiler-leak failure at 04:58, its ninth 2026 outage, triggering the SEN to split east of Ciego de Ávila at 06:09. Granma, Santiago de Cuba and Guantánamo ran on local microsystems for several hours.Source: Granma / UNE
How much fuel does Cuba consume each day?: Cuba consumes 90,000 to 110,000 Barrels Per Day against domestic production of 40,000 Barrels Per Day, leaving a 50,000-70,000 barrel daily import requirement now squeezed by the loss of Venezuelan supply since November 2025.Source: Vicente de la O Levy, Mesa Redonda 13 May 2026
What is Executive Order 14404 on Cuba?: EO 14404 was signed by President Trump on 1 May 2026 and numbered formally that week. It authorises personal SDN designations against Cuban officials and their adult relatives; the first designee was Ania Guillermina Lastres Morera on 7 May 2026. It operates in parallel with EO 14380's secondary-tariff fuel architecture.Source: Federal Register
Did Marco Rubio meet the Pope about Cuba?: Yes. Secretary of State Marco Rubio held a 45-minute audience with Pope Leo XIV at the Holy See on 9 May 2026, covering Cuba and Venezuela. The meeting produced a US proposal to route humanitarian aid to Cuba through the Catholic Church rather than through GAESA or state channels.Source: Vatican / State Department
When did Venezuelan oil supply to Cuba actually stop?: Cuban Energy Minister Vicente de la O Levy confirmed on 13 May 2026 that Venezuelan crude shipments to Cuba had stopped in November 2025, four months before the 18 March 2026 PDVSA carve-out previously framed as the proximate cause.Source: Vicente de la O Levy, Mesa Redonda

Background

Cuba is a one-party socialist state under the Communist Party, governed since 2019 by President Miguel Díaz-Canel. Its economy is heavily statised, dominated by GAESA (the military conglomerate) which controls roughly 60% of hard-currency revenue, and has been under a US embargo since 1962. With a population of approximately 11.1 million, the island consumes roughly 90,000 to 110,000 barrels of fuel per day against domestic production of 40,000 Barrels Per Day, leaving it structurally dependent on Russian and Venezuelan crude. The UN Resident Coordinator assessed in April 2026 that approximately 2 million Cubans across 8 provinces require humanitarian assistance.

By mid-May 2026 two parallel US Cuba sanctions architectures operate. Executive Order 14380 (29 January 2026) imposes secondary tariffs on third-country fuel suppliers. Executive Order 14404 (1 May 2026) authorises personal designations against named officials and adult relatives, with Ania Guillermina Lastres Morera added to the SDN list on 7 May as the first individual under the [Cuba-EO] tag. Cuba General License 1, published 7 May, is a savings clause aligning EO 14404 with the pre-existing Cuban Assets Control Regulations and grants no fuel-delivery authority. OFAC's General Licence 134B (Russia programme wind-down) expired 16 May with no Cuba-specific successor, leaving the Sovcomflot Universal's 270,000 barrels of diesel outside any authorisation envelope.

The energy crisis remains the operative domestic frame. On 14 May 2026 at 06:09 the Sistema Eléctrico Nacional (SEN) fragmented east of Ciego de Ávila, leaving Granma, Santiago de Cuba and Guantánamo on local microsystems for several hours after the Antonio Guiteras thermoelectric plant suffered its ninth 2026 failure. Bloomberg satellite analysis confirmed Cuban nighttime light fell by up to 50% across the island. Cuban Energy Minister Vicente de la O Levy told Mesa Redonda on 13 May that Venezuelan crude supply has been interrupted since November 2025, four months earlier than the previously framed 18 March 2026 carve-out, and described the situation as 'out of fuel'. Diplomatically, Secretary Marco Rubio's 9 May Vatican audience with Pope Leo XIV revived a humanitarian channel that runs alongside the bilateral track opened 10 April and the Treasury personal-designations track.
