The Fenne power plant in Völklingen in Saarland consists of several systems, namely the Völklingen model power plant (MKV), the Völklingen thermal power station (HKV), the thermal power station (Fenne I), a gas engine system and a gas turbine . The district heating output is approx. 600 megawatts , making it one of the largest German district heating network systems. The operator and owner is Steag Power Saar GmbH.
Fenne I.
The Fenne location has been used as a power plant location since 1924. A 60 megawatt power plant was built in 1923 and commissioned in 1924. The energy obtained was used for coal extraction. The Second World War prevented further expansion . A new machine set was not installed until 1960. In 1972 two new steam boilers were installed.
The machine house and the boiler house are under monument protection .
Fenne II and III
The construction of Fenne II began in 1954. It was a block-type power plant that produced two times 72.5 MW of electrical output. It was put into operation in 1962 and was the first to serve the public. The Fenne III block was put into operation in 1967 and only needed a boiler and a turbine. In total it delivered 163 MW. It was shut down and demolished in 1996. Fenne II and III were replaced by the thermal power station. Another block, Fenne IV, was planned for 1972, but this was not implemented for environmental reasons.
Fenne model power plant
The model power plant was put into operation on August 26, 1982 and has an electrical output of 179 MW. It was planned and built as a prototype for other power plants. Special technical features are the cooling tower , which discharges completely wet-cleaned flue gases, optimized burners that do not require a catalyst , and the combination of a gas turbine with a fluidized bed furnace . Because it is disposed of via the cooling tower, it is also referred to as a “chimney-free power plant”. In 1991 it won the international power plant award from the US American trade journal Power International . The model power plant supplies district heating to Saarbrücken and Völklingen.
Fenne thermal power station
The cogeneration plant is the youngest power plant in the group and was put into operation on November 30, 1989 with an electrical output of 211 MW. It is mainly fed by coal, but can also be fed by mine gas methane and coke gas. It replaced Fenne II and III. In 2002 and 2003, the power plant was expanded to include eight mine gas-fired gas engines, and in 2004 a further six gas engines were retrofitted. This means that the world's largest mine gas-powered engine system with an output of 42 MW has been installed there. The combined heat and power plant supplies 200 MW of electricity and 185 MW of district heating.
