Mintia-Deva power station is a 1,075 MW coal power station in Hunedoara, Romania. It is operated by SC Complex Energetic Hunedoara. Based on reported annual generation of 777 GWh, it can supply roughly 222k homes. It ranks #5 of 97 Romania power plants by installed capacity. In context, coal supplies about 13.4% of Romania's electricity; the national grid averages 251 gCO₂/kWh (67.5% low-carbon) (2025).

At 1,075 MW, Mintia-Deva power station is well above the median coal plant in Romania (262 MW). Technically it is described as Siemens Energy: SGT5-9000HL, Siemens Energy: SST5-5000; subcritical. Its current lifecycle status is “construction” — 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 warm-summer humid continental climate (Köppen Dfb) — Northern Hemisphere, latitude 45.9°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 25% 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.
The #3 largest coal power plant of 20 in Romania by capacity.
Romania has 20 coal power plants in this dataset, together about 9,517 MW of capacity.
