Sliven power station is a 60 MW coal power plant in Sliven, Bulgaria. It is operated by Toplofikacia Sliven EAD [100%]. Based on its capacity (estimated), it can supply roughly 75k homes (estimated). It ranks #32 of 55 Bulgaria power plants by installed capacity. Commissioned in 1969, it is around 57 years old — an older, legacy facility. Its annual emissions of 75,617 t CO₂/yr (EU ETS verified (EUTL 2023)) are equivalent to about 18k cars driven for a year. In context, coal supplies about 22.5% of Bulgaria's electricity; the national grid averages 276 gCO₂/kWh (71.9% low-carbon) (2025).

In context: how this plant compares
At 60 MW, Sliven power station is below the median coal plant in Bulgaria (180 MW). 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.

Climate zone & how it works
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 42.7°N — which shapes how much energy it can produce and how its output varies through the year.
Climate zone & typical temperatures: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid).
Site climate & environmental severity
This site sits in a moderately corrosive environment (estimated ISO 9223 class C3 — Medium), with humidity / wetness the leading environmental stress.
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.
