The Jena thermal power station is located in Winzerla in the south of Jena . It was built in 1969 after the Council of Ministers of the GDR had decided in 1965 that because of the expansion of Zeiss -Werke and the associated increase of the population, especially by the newly established district Neulobeda , a private power station to be built in Jena. The foundation stone was laid on April 17, 1968. When it was completed, it consisted of a thermal power station, a transformer station and an 8-storey multi-purpose building. The investment volume was 200 million marks.
The Jena thermal power station was operated with heavy heating oil after it was commissioned in 1972 . During the global oil crisis, it was partially converted from 1979 onwards to the local energy source lignite ; the oil boilers were only used when there was a high demand for heat (outside temperature below −5 ° C) and as a reserve. The power plant received a dedusting system for exhaust gas cleaning , but no flue gas desulphurisation . Around 800,000 tons of carbon dioxide and 18,000 tons of sulfur dioxide were emitted each year . The coal combustion required the construction of the second large chimney (225 meters) in order not to directly pollute the city and the Saale valley with the pollutants of lignite. While in the oil firing a simple siding from the railway Göschwitz had sufficient ago, an extensive was for the transport of the lignite railway siding with sidings, Auftauhalle and unloading facilities for all common types of open freight cars built. The ashes were transported by rail from a loading facility on Lobedaer Strasse to the Wismut mining region near Gera to serve as backfill material . The operation took place with steam storage locomotives , only alternatively with a diesel locomotive of the DR class V 60 .
After the political change in the GDR, the gas supply was switched from town gas to the more energy-rich natural gas , and the costly coal burning could be stopped. The last coal train reached the power plant on June 20, 1994. After the coal supply had been used up, the power plant was partially shut down and officially put back into operation on September 16, 1996 after two years of conversion to natural gas and trial operation. Since then, as the largest steam power plant in Thuringia, it has been one of the most modern combined cycle power plants in Germany. The electric power is 197 mega watts and the district heating capacity 225 MW. In 2011 there was another renovation with heat storage, summer boiler and more efficient operation. From 2019 to 2021, six gas engines with 10 megawatts each and a heat storage system with 600 megawatt hours of capacity are to be added; the gas turbines then only have to be operated in winter. The investment pays off thanks to a district heating purchase agreement that runs until 2037. In this expansion stage, 150,000 tons of carbon dioxide are emitted per year.
The power plant is now operated by Thüringer Energie AG, and the district heating produced is supplied to Stadtwerke Energie Jena-Pößneck . About half of all Jena apartments are supplied with heating and hot water by the power plant. The power plant including the extracted district heating power has an efficiency of 70 percent. The grid connection takes place at the 110 kV high voltage level in the power grid of the distribution network operator TEN Thüringer Energienetze .
The cityscape was shaped by the two chimneys for several decades. The 225-meter-high coal-burning chimney, which has not been needed since 1994, was the tallest structure in Thuringia until spring 2019. On June 28, 2018, preparations for the demolition began, which finally started on April 11, 2019 and lasted around 4 months. Similar to the demolition of the chimneys in Gera, a spider excavator was used to work from top to bottom, and the resulting rubble fell inside. In the medium term, the 185-meter-high neighboring chimney should also disappear. After the chimneys in Erfurt-Ost and Gera have been demolished, this "smaller" chimney will be the second tallest structure in Thuringia after the Bleßberg transmitter . After that, the Jentower would be the tallest structure in the Free State.
