Oslomej power station — North Macedonia

Oslomej power station is a 254.5 MW coal power station in North Macedonia, North Macedonia. It is operated by Elektrani na Severna Makedonija AD [100%]. Based on its capacity (estimated), it can supply roughly 318k homes (estimated). It ranks #4 of 6 North Macedonia power plants by installed capacity. Commissioned in 1980, it is around 46 years old — long-established.

Capacity provenance

The public capacity above is the current source-record value. A 2026 tracker candidate lists 125 MW for Oslomej power station, but it is not used as the public primary value until scope is verified (unit vs operating vs installed/project total).

Data provenance

capacity: GEM · 2026 · L100000101867; fuel: GEM GCPT

In context: how this plant compares

Technically it is described as subcritical. Coal plants burn pulverised coal to raise high-pressure steam for a turbine; they run as baseload but are the most carbon-intensive mainstream source and the first targeted for retirement or efficiency retrofits.

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

Local climate & thermal context

This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a temperate oceanic climate (Köppen Cfb) — Northern Hemisphere, latitude 41.6°N — which shapes how much energy it can produce and how its output varies through the year.

Monthly mean temperature

Heating degree-days here run 38% above the median power plant in this dataset — a proxy for how much extra energy heated equipment must replace through its surfaces in winter.

Climate heat-demand index: 73/100 — this site sits in the top third of the power plants we cover by heating degree-days.

Climate normals: WorldClim 2.1 (1970–2000 monthly normals, 10 arc-min, CC BY 4.0); zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid). Degree-days & heat-demand index computed by PowerAtlas — a modelled heat-demand proxy, not a measured site figure.

Site climate & environmental severity

This site sits in a moderately corrosive environment (estimated ISO 9223 class C3 — Medium), with humidity / wetness the leading environmental stress.

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.
