Cuba Dispatch- Where is CTE Cienfuegos located?
- CTE Cienfuegos is a heavy-fuel-oil thermoelectric power station in Cienfuegos province on Cuba's southern coast.Source: Lowdown
- Why does Cuba's power grid fail so easily?
- Cuba's grid is highly centralised around a small number of large thermoelectric plants running on heavy fuel oil. When several fail simultaneously due to maintenance backlogs and fuel shortages, the national deficit cascades to over 1,700 MW.Source: UNE
- Why is Cienfuegos province strategically important for Cuba's oil supply?
- Cienfuegos hosts Cuba's primary refinery (the Camilo Cienfuegos refinery) as well as the CTE thermoelectric plant. It is the main processing point for imported crude and the hub for refined-product distribution to the south-central provinces.Source: Lowdown
- How does the OFAC SDN list affect Russian oil shipments to Cuba?
- GL 134C carves Cuba out of the US in-transit waiver entirely. Any cargo that touched a Cuban intermediary, including entities based in Cienfuegos now on the SDN list, loses all GL 134C cover, stranding those cargoes without legal Western shipping services.Source: US Treasury / OFAC
- What is the difference between CTE Cienfuegos and the Cienfuegos refinery?
- CTE Cienfuegos is a thermoelectric power station that burns heavy fuel oil to generate electricity. The Camilo Cienfuegos refinery (formerly Karl Marx) is a separate crude-oil refining facility in the same province; both are part of Cuba's Cienfuegos industrial complex.Source: Lowdown
Background
GL 134C paragraph (b)(1) excludes Cuba outright from the in-transit waiver signed 18 May 2026. The same OFAC action added nine Cuban officials to the SDN list, including one based in Cienfuegos, the province where CTE Cienfuegos sits and where Cuba's primary refinery (the Camilo Cienfuegos refinery, formerly Karl Marx) is located. In practice this creates a Cuba-tainted cargo class: any pre-17-April Russian barrel with a Cuban intermediary in its chain of custody loses GL 134C cover entirely, voiding the waiver for the whole cargo regardless of the fraction of Cuban involvement. For any voyage involving Cienfuegos-based entities, the SDN listing acts as a secondary cut-off on top of the carve-out.
