In context: how this plant compares

At 51 MW, Stewart & Stevenson is well above the median oil plant in Guatemala (44 MW). Technically it is described as OCGT. 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.
