Sliven power station

Coal power plant in Sliven, Bulgaria. Approximate location 42.654762, 26.325853.

CoalSlivenBulgariaCO₂ measured

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).

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 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.

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

75,617 t CO₂/yr — in everyday terms

This facility's annual emissions are roughly equivalent to:

18kpassenger cars driven for a year
9.9khomes' yearly energy use
1.3 milliontree 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 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.

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.
