Marbach power station

Oil power plant in Baden-Württemberg, Germany. Approximate location 48.92808, 9.23109.

OilBaden-WürttembergGermanyCCGT · HRSGCO₂ measured

Marbach power station is a 695 MW oil power station in Baden-Württemberg, Germany. It is operated by EnBW Energie Baden-Württemberg AG [100%]. Based on its capacity (estimated), it can supply roughly 522k homes (estimated). It ranks #69 of 1,442 Germany power plants by installed capacity. Commissioned in 1970, it is around 56 years old — an older, legacy facility. Its annual emissions of 46,906 t CO₂/yr (EU ETS verified (EUTL 2023)) are equivalent to about 11k cars driven for a year. In context, oil supplies about 3.8% of Germany's electricity; the national grid averages 330 gCO₂/kWh (59.1% low-carbon) (2025).

In context: how this plant compares

At 695 MW, Marbach power station is well above the median oil plant in Germany (88 MW). Technically it is described as CCGT; combined-cycle with a heat-recovery steam generator (HRSG). Oil-fired plants burn heavy fuel oil or diesel, usually as peaking or backup capacity on islands and grids without gas pipelines; high fuel cost keeps their utilisation low.

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

46,906 t CO₂/yr — in everyday terms

This facility's annual emissions are roughly equivalent to:

11kpassenger cars driven for a year
6.1khomes' yearly energy use
782ktree seedlings grown 10 years to absorb it

Equivalencies via US EPA Greenhouse Gas Equivalencies; emissions per EU ETS verified (EUTL 2023) (measured for US EPA/EU ETS, modelled for Climate TRACE).

Climate zone & how it works

This oil plant burns oil or diesel to drive turbines or reciprocating engines. It sits in a temperate oceanic climate (Köppen Cfb) — Northern Hemisphere, latitude 48.9°N — which shapes how much energy it can produce and how its output varies through the year.

Site climate & environmental severity

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.
