[3] The Trbovlje Chimney (Trboveljski dimnik) of the power station, built in 1976, is the tallest flue-gas stack in Europe.

A high chimney was required for the site to ensure that emissions were removed from the deep, narrow valley under all weather conditions.

On that day, the new coal-fired thermal power plant along the Sava River started operating, after the first thermal power plant at Vode in Trbovlje ceased to operate due to insufficient capacity, lack of sufficient water, proximity to residential settlements and other circumstances.

For these experiments, a large wooden tub with built-in water resistors was prepared outside the power plant along the north wall.

In the first, a large thermal power plant for coal at the time, but small for today's conditions, it was produced with three steam-powered generators with a piston.

The enlarged and modernized Trbovlje power plant began operating, albeit not at full capacity, in early 1939.

One of these forms was the prevention and slowing down of construction and assembly works during the expansion of the Trbovlje power plant in the years 1942 to 1944, about which we state the data in the second place.

As early as January 1943, one blade of the low-pressure part of the Siemens turbine broke off when it was idling in the presence of the installer and assembly engineer of the supplier company.

During the revision of the turbine by a Siemens installer, the rotor blades were intentionally damaged due to improper use of the crane otherwise electrified in a domestic power plant.

With such and similar actions of domestic workers, the production of electricity, which was still needed by the German war industry in particular, was disabled for a certain period of time.

He emphasized the necessity and justification of the construction, with special regard to the large reserves of low-calorie coal lying in the area of the Zasavje districts.

The strongest argument for the construction of a new thermal power plant was in the large coal reserves, especially in the Trbovlje area.

After a lengthy determination of the causes, the authorized experts found that the suppliers of TPP Morava equipment did not dimension the boiler for the Trbovlje thermal power plant in relation to the delivered sample shipments of coal to Poland, and above all did not take into account the ash melting point.
