OilMayabequeCubaSteamAnnounced
Termoeléctrica de Santa Cruz power station is a 495 MW oil power station in Mayabeque, Cuba. It is operated by Unión Eléctrica de Cuba [100%]. Based on its capacity (estimated), it can supply roughly 372k homes (estimated). It ranks #4 of 22 Cuba power plants by installed capacity. In context, oil supplies about 82.3% of Cuba's electricity; the national grid averages 643 gCO₂/kWh (4.0% low-carbon) (2024).

Known, modelled and calculated values are kept separate. Missing fields are shown as unavailable.
The public capacity above is the current source-record value. A 2026 tracker candidate lists 295 MW for Termoeléctrica de Santa Cruz power stati, but it is not used as the public primary value until scope is verified (unit vs operating vs installed/project total).
The capacity and fuel fields on this page are source-record values from the upstream open dataset. They are useful for identification and ranking, but they have not been upgraded to a 2026 registry/GEM-location verified value.

At 495 MW, Termoeléctrica de Santa Cruz power station is well above the median oil plant in Cuba (370 MW). Technically it is described as Steam. Its current lifecycle status is “Announced” — so it is not yet, or no longer, generating at full output. Oil-fired plants burn heavy fuel oil or diesel, usually as peaking or backup capacity on islands and grids without gas pipelines; high fuel cost keeps their utilisation low.

This oil plant burns oil or diesel to drive turbines or reciprocating engines. It sits in a tropical savanna climate (Köppen Aw) — Northern Hemisphere, latitude 23.0°N — which shapes how much energy it can produce and how its output varies through the year.
Climate zone & typical temperatures: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid).
For a plant’s outdoor hardware — heat-recovery steam generators (HRSG), expansion joints, valves, flanges and their insulation — the local climate sets how fast unprotected steel and coatings degrade. This site sits in an aggressive, high-corrosion environment (estimated ISO 9223 class C5 — Very high), with marine salt corrosion the leading environmental stress.
Higher environmental severity is exactly where protective removable insulation pays back most: a sheltered micro-climate slows corrosion, UV and thermal-cycling damage and extends outdoor hardware service life. This is an indicative site-climate context — not a condition assessment of any specific plant or operator.
Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.
The #3 largest oil power plant of 16 in Cuba by capacity.
Cuba has 16 oil power plants in this dataset, together about 5,165 MW of capacity.
