Oroszlány power station is a 250 MW coal power station in Komarom-Esztergom, Hungary. It is operated by MVM Vertesi Eromu Zrt. Based on its capacity (estimated), it can supply roughly 313k homes (estimated). It ranks #13 of 37 Hungary power plants by installed capacity. Commissioned in 1962, it is around 64 years old — an older, legacy facility. In context, coal supplies about 3.4% of Hungary's electricity; the national grid averages 163 gCO₂/kWh (75.3% low-carbon) (2025).

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 130 MW for Oroszlány power station, but it is not used as the public primary value until scope is verified (unit vs operating vs installed/project total).
Capacity claim grade: B_SCOPE_PARENT_COMPLEX - recommended action: build_parent_complex_model - confidence: not_comparable_without_scope. This follows a claim-based data model: value + scope + source + confidence, rather than silently overwriting records.
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 250 MW, Oroszlány power station is below the median coal plant in Hungary (400 MW). Technically it is described as subcritical. Its current lifecycle status is “mothballed” — so it is not yet, or no longer, generating at full output. 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.

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 47.5°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 24% 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: 64/100 — this site sits in the mid 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.
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 a mild atmospheric environment (estimated ISO 9223 class C2 — Low), with humidity / wetness 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.
