Horsens power station is a 34 MW gas power plant in Midtjylland, Denmark. It is operated by Ørsted A/S [100%]. Based on its capacity (estimated), it can supply roughly 38k homes (estimated). It ranks #31 of 57 Denmark power plants by installed capacity. Commissioned in 1991, it is around 35 years old — long-established. Its annual emissions of 49,677 t CO₂/yr (EU ETS verified (EUTL 2023)) are equivalent to about 12k cars driven for a year. In context, gas supplies about 2.4% of Denmark's electricity; the national grid averages 114 gCO₂/kWh (91.2% low-carbon) (2025).

In context: how this plant compares

At 34 MW, Horsens power station is below the median gas plant in Denmark (55 MW). Technically it is described as CCGT; combined-cycle with a heat-recovery steam generator (HRSG); GE Power: LM250PE. 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.

49,677 t CO₂/yr — in everyday terms

This facility's annual emissions are roughly equivalent to:

12kpassenger cars driven for a year
6.5khomes' yearly energy use
828ktree 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 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 55.9°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 moderately corrosive environment (estimated ISO 9223 class C3 — Medium), 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.
