Brestanica (TEB) is a 337 MW gas power station in Krsko, Slovenia. It is operated by Termoelektrarna Brestanica doo [100%]. Based on reported annual generation of 10 GWh, it can supply roughly 2.7k homes. It ranks #3 of 10 Slovenia power plants by installed capacity. Commissioned in 1975, it is around 51 years old — an older, legacy facility. Its annual emissions of 3,929 t CO₂/yr (EU ETS) are equivalent to about 916 cars driven for a year. In context, gas supplies about 6.4% of Slovenia's electricity; the national grid averages 183 gCO₂/kWh (78.9% 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 337 MW for Brestanica (TEB) 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: A1_APPLY_CANDIDATE_LOW_DELTA - recommended action: candidate_primary_after_spot_check - confidence: medium_high_after_sample. This follows a claim-based data model: value + scope + source + confidence, rather than silently overwriting records.
The capacity and/or fuel fields on this page include a source-backed provenance label from GEM, an official registry, Wikidata, OSM, or a cross-source match.

Technically it is described as OCGT. Gas plants burn natural gas either in open-cycle turbines for fast peaking, or in combined-cycle units that recover exhaust heat in an HRSG to reach roughly 55–62% efficiency — the cleanest-burning fossil option.

This gas plant burns natural gas in a turbine — often in a combined-cycle setup — to generate electricity. It sits in a temperate oceanic climate (Köppen Cfb) — Northern Hemisphere, latitude 46.0°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 21% 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: 62/100 — this site sits in the mid third of the power plants we cover by heating degree-days.
A gas turbine here also runs ~0% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).
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.
