EG Mariel power station is a 147.4 MW oil power station in Artemisa, Cuba. It is operated by Unión Eléctrica de Cuba [100%]. Based on its capacity (estimated), it can supply roughly 111k homes (estimated). It ranks #17 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).

At 147.4 MW, EG Mariel power station is below the median oil plant in Cuba (370 MW). Technically it is described as Engine. Its current lifecycle status is “Mothballed” — 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 #14 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.
