Heilbronn power station is a 1,066 MW coal power station in Baden-Wuerttemberg, Germany. It is operated by Energie Baden-Württemberg. Based on reported annual generation of 2,389 GWh, it can supply roughly 683k homes. It ranks #38 of 1,442 Germany power plants by installed capacity. Commissioned in 1977, it is around 49 years old — long-established. Its annual emissions of 425,288 t CO₂/yr (EU ETS verified (EUTL 2023)) are equivalent to about 99k cars driven for a year. In context, coal supplies about 20.6% of Germany's electricity; the national grid averages 330 gCO₂/kWh (59.1% low-carbon) (2025).

The public capacity above is the current source-record value. A 2026 tracker candidate lists 1,066 MW for Heilbronn 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: A2_GENERAL_REVIEW - recommended action: manual_source_check - confidence: medium_low. 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.

At 1,066 MW, Heilbronn power station is well above the median coal plant in Germany (296 MW). Technically it is described as GE Power: 9HA.01, GE Power: STF-D650; 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.

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 49.2°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 #19 largest coal power plant of 124 in Germany by capacity.
