In context: how this plant compares

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.

Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.
