Republika power station is a 105 MW coal power station in Pernik, Bulgaria. It is operated by Toplofikacia Pernik Ead. Based on its capacity (estimated), it can supply roughly 131,400 homes (estimated). It ranks #20 of 43 Bulgaria power plants by installed capacity. Commissioned in 1951, it is around 75 years old — an older, legacy facility. In context, coal supplies about 22.5% of Bulgaria's electricity; the national grid averages 276 gCO₂/kWh (71.9% low-carbon) (2025).

This facility's annual emissions are roughly equivalent to:
Estimated, not measured: from installed capacity at a typical 50% load factor × a typical coal emission factor (~1000 g CO₂/kWh, IPCC AR5 / US EIA). Actual emissions depend on plant efficiency and running hours.Equivalencies via US EPA Greenhouse Gas Equivalencies.

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 42.6°N — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
Heating degree-days here run 39% 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: 74/100 — this site sits in the top third of the power plants we cover by heating degree-days.
In colder climates, uninsulated hot equipment (boilers, turbines, valves, steam lines) loses proportionally more heat to ambient air — exactly the loss Inzonex modular insulation is designed to cut.

The #11 largest coal power plant of 11 in Bulgaria by capacity.
Bulgaria has 11 coal power plants in this dataset, together about 4,859 MW of capacity.
