HKW 1 Werk Offstein

Gas power plant in Rheinland-Pfalz, Germany. Approximate location 49.5991, 8.221.

GasRheinland-PfalzGermanyCO₂ modelled

HKW 1 Werk Offstein is a 30 MW gas power plant in Rheinland-Pfalz, Germany. It is operated by Südzucker AG Mannheim/Ochsenfurt. Based on its capacity (estimated), it can supply roughly 34k homes (estimated). It ranks #449 of 1,442 Germany power plants by installed capacity. Commissioned in 1992, it is around 34 years old — long-established. Its modelled annual emissions are 29,784 t CO₂/yr (Climate TRACE), equivalent to about 6.9k cars driven for a year. In context, gas supplies about 16.5% of Germany's electricity; the national grid averages 330 gCO₂/kWh (59.1% low-carbon) (2025).

Data provenance

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.

In context: how this plant compares

At 30 MW, HKW 1 Werk Offstein is below the median gas plant in Germany (53 MW). 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.

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

~29,784 t CO₂/yr (modelled) — in everyday terms

This facility's annual emissions are roughly equivalent to:

6.9kpassenger cars driven for a year
3.9khomes' yearly energy use
496ktree seedlings grown 10 years to absorb it

Local climate & thermal context

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 49.6°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 18% 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: 59/100 — 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.

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.
