The Trbovlje Power Station () was a lignite-fired power station on the bank of the Sava River near Trbovlje, Slovenia. The plant was operated by Termoelektrarna Trbovlje d.o.o. It was used as a reserve unit for the Slovenian electric system.
The Trbovlje Chimney () of the power station, built in 1976, is the tallest flue-gas stack in Europe. The high flue-gas stack was poured in 210 days, and required of concrete and 1,079 tons of reinforcing steel. A high chimney was required for the site to ensure that emissions were removed from the deep, narrow valley under all weather conditions.
In November 2014 it was announced that the power station would be shut down; the station was closed in 2016 after several years dormant.
In 2020, the climbers Janja Garnbret and Domen Škofic climbed an artificial climbing route created up the 360-metre chimney for the film 360 Ascent.
