The geothermal heating plant in Unterschleißheim is an environmental project in the city Unterschleißheim (pioneer project of using geothermal Energy in the region of munich).
GTU ist the city-owned company which was found in the Year 2000 and is responsible for planning, building and operation of geothermal plants for the supply of heat (responsible for the operation is a external system operator).
The geothermal heating plant is in operation since 2003. GTU uses geothermal water with around 80 °C from a depth of around 2000 m for the purpose of heating parts of Unterschleißheim.
Today the geothermal heating plant provides heat for 294 residential buildings with about 4.300 flats as wells as 15 industrial buildings and 16 municipal buildings.
The installed capacity of the geothermal doublet system is around 7 MW. With that geothermal doublet system base load energy can be supplied. To supply peak load energy there are three gas and oil fired boilers installed with a thermal capacity between 9.9 MW and 6.5 MW.
The heat is distributed by a district heating system and about 65 to 70 percent of the heat is supplied by the hot geothermal water. GTU wants to install a heating pump to raise this renewable share.
Within the MALEG-Project GTU will provide space in the bulding of the heating plant where the demonstrator can be situated and can be connected to the geothermal pipeline to use the geothermal water for the demonstrator experiments. Furthermore, GTU provides hydrochemical and operational data for the project partners.
