Timeline for Camilo Cienfuegos refinery
Resumed operations on 17 April after roughly four months offline, routing Kolodkin crude to the grid
Cuba Dispatch: Refinery restart cuts grid deficit to 1,395 MW- What is the Camilo Cienfuegos refinery and why does it matter for Cuba's power cuts?
- The Cienfuegos refinery is Cuba's largest oil processing facility with a design capacity of 65,000 bpd. When it shuts down, fuel for electricity generators disappears, causing island-wide blackouts. It restarted in April 2026 on Russian crude, cutting the grid deficit from 1,732 to 1,395 MW.Source: event
- Where does Cuba get oil for its refinery?
- As of 2026, the Cienfuegos refinery runs on Russian crude delivered by Sovcomflot tankers using OFAC General Licence 134B sanctions cover. Cuba's own production is negligible; Venezuelan deliveries have become unreliable.Source: event
- What is the Camilo Cienfuegos refinery and why does it matter?
- The Camilo Cienfuegos refinery is Cuba's largest petroleum processing facility, with a design capacity of approximately 65,000 Barrels Per Day, operated by CUPET in Cienfuegos province. It is the primary source of refined fuel for Cuba's electricity generators; prolonged outages directly translate into grid deficits and nationwide blackouts.Source: entity background
- Why did the Cienfuegos refinery restart in April 2026?
- The refinery restarted on 17 April 2026 after roughly four months offline, when Russian crude delivered by the Sovcomflot tanker Anatoly Kolodkin arrived under OFAC General Licence 134B. Cuba's Energy Minister Vicente de la O Levy announced the restart cut the National Grid deficit from 1,732 MW to 1,395 MW within days.Source: event 2845
- How long did the April 2026 Cienfuegos refinery restart last?
- The April restart was partial and short-lived. Energy Minister de la O Levy warned publicly that the fuel from a single ship would last only until end of April. By 4 May 2026, Díaz-Canel admitted the Russian crude was 'already running out' and Cuba had 'no certainty about the arrival of another shipment,' while the Universal tanker was drifting 1,000 nautical miles away.Source: event 3081
- Who built the Camilo Cienfuegos refinery?
- The refinery was originally built with Soviet assistance in the 1980s and was partially modernised with Venezuelan investment in the 2000s under the ALBA energy cooperation framework. It is operated by CUPET, Cuba's state oil company.Source: entity background
- How does Cuba's refinery affect its power grid?
- The Cienfuegos refinery is the primary domestic source of refined fuel for Cuba's thermal power stations. Each time it shuts down, fuel for generators runs out within weeks and grid deficits expand. The April 2026 restart reduced the deficit by 337 MW; when the crude ran out and the Antonio Guiteras plant also failed in May, the deficit returned toward 1,680 MW.Source: entity background
Background
The Camilo Cienfuegos refinery is Cuba's largest petroleum processing facility, located in the Cienfuegos province on the island's southern coast. It has a design capacity of approximately 65,000 Barrels Per Day but has operated well below that level for years due to maintenance backlogs, feedstock shortages, and equipment deterioration. The refinery was originally built with Soviet assistance in the 1980s and was partially modernised with Venezuelan investment in the 2000s under the ALBA energy cooperation framework. It is operated by CUPET (Cuba Petroleum), the state oil company. The facility is the primary source of refined fuel for Cuba's electricity generators, road transport, and industrial base; prolonged outages directly translate into grid deficits and blackouts across the island.
In April 2026, the refinery restarted after receiving Russian crude delivered by the Sovcomflot tanker Universal under OFAC General Licence 134B. Cuba's Energy Minister Vicente de la O Levy announced that the restart cut the National Grid deficit from 1,732 MW to 1,395 MW within days. The refinery's operational status has become the single most watched indicator of Cuba's energy trajectory: each restart or shutdown determines whether the island's fragile grid can hold or collapses into 20-hour blackouts. The April restart was partial; the refinery was not operating at full capacity.
