Coal-Fired Plants in Slovenia

Sostanj
Location: Slovenia
Operator: Termoelektrarna Sostanj po
Configuration: 2 X 30 MW (ret), 1 X 75 MW, 1 X 275 MW, 1 X 345 MW, 1 X 600 MW CHP
Operation: 1956-2015
Fuel: lignite
Boiler supplier: Sulzer, Deutsche Babcock, Alstom
T/G supplier: Escher Wyss, Oerlikon, Siemens, Alstom
EPC: Siemens, Alstom, Primorje
Quick facts: Sostanj is the largest thermal power plant in Slovenia and produces electricity and heat using fuel from the Velenje lignite coal mine. Extensive back-end pollution control equipment was added in 2000 and Units 4&5 were updated with 45-MW topping gas turbines. In Aug 2008, Alstom secured the equipment supply and EPC contract for a 600-MW USC unit for the plant. Sostanj-6 was synchronized in Oct 2014 and brought to full load for the first time the following month. The project was very controversial, in part due to the fact that costs doubled to over €1.4bn. Large loans were secured from the EIB (€550mn) and the EBRD (€100mn).

Te-Tol Ljubljana
Location: Slovenia
Operator: Termoelektrarna Toplarna doo
Configuration: 1 X 42 MW, 1 X 32 MW, 1 X 50 MW CHP
Operation: 1967-1983
Fuel: coal, wood
Boiler supplier: ??
T/G supplier: Westinghouse, Jugo, Koncar
Quick facts: Te-Tol is jointly owned by the Slovenian government (64.57%) and the City of Ljubljana (35.43%). Coal burn is about 500,000 tpy with average output of 390,000 MWh of electricity and 140,000 tpy of process steam, about 90% of the city's district heating requirement.  The plant has been extensively modernized with baghouses added on Units 1&2, boiler modifications on all three units to reduce emissions and improve efficiency, addition of a heat-storage tank, and a new 110kV switchyard. IN 2010, Unit-3 began burning wood chips.

Trbovlje-4
Location: Slovenia
Operator: Termoelektrarna Trbovlje doo
Configuration: 1 X 125 MW
Operation: 1966
Fuel: lignite
Boiler supplier: Rafako
T/G supplier: Zamech, Dolmel
Quick facts: This modestly-sized coal-fired unit has the tallest power plant stack in Europe at 360m. The new chimney replaced the original 80m stack, which was unable to evacuate emissions from the narrow valley under certain temperature conditions. The second stack was poured in 210 days and tapers from a bottom diameter of 27.5m to 7.7m at the top. In total, 11,866m of concrete, 1,079t of reinforcing steel, and 950t of refractory were required for construction. The stack contractor was Karrena GmbH. The steam unit was modernized in 1999. The site also hosts two 32-MW combustion turbines.
