Termoelektrarna Toplarna Ljubljana is a thermal power plant in Ljubljana, that consists of three units with generation capacities of 42 MW, 32 MW, and 50 MW. Operating since 1966, the thermal plant produces both heat and electricity using brown coal and wood biomass for the surrounding area.

The plant is unique because it was colorfully painted in the 1990s, making it stand out from all other structures in the area.

Back then, a closed gallery around the chimney was added. The gallery looks like an observation deck from the outside and may even be accessible by elevator, but tourists can't gain entry. The gallery houses equipment for exhaust monitoring.

In 2014, the plant will stop burning most coal and switch over to natural gas.
