Ulm– City in a Climate Alliance
FUG is THE heat supplier in Ulm:
ca. 45 % of the entire heat demand of the city is being produced by FUG.
The best energy is the one that is not being used.
The remaining energy should be used as efficiently and climate-friendly as possible.
Independence from imported energies.
Heat supply 4,2 %
Electricity supply 9,3 %
Germany 2020 (declared intentions)
Heat and electricity supply 20 % each
50% share of renewable energies, incl. Energy from the MHKW Donautal
Outlook FUG from 2011
80% share of renewable energies

FUG is open to concepts from private investores:
Since1996 FUG buys surplus heat from saw dust from a big wood manufacturing plant.
Since 1997 FUG buys surplus heat from a waste incineration plant
Since 2006 surplus heat from a private biogas plant with a capacity of 500 kW is being fed into the network Wiblingen eingespeist .
In 2 month, a 1,7 km preinsulated pipe (under construction) will connect a a biogas plant in Gögglingen that is twice that size.
A further biogas plant is in the authorisation process.

Almost complete independence from imported energies
Decentral electricity production
BioHeating Plant I+IIca. 160 Mio. KWh
CHPca. 20 Mio. KWh
M Heating Plantca. 60 Mio. KWh
Biogas Anlagen ca. 15 Mio. kWh
Total:ca. 255 Mio. KWh
This correspondes to 39% of the entire electricity demand in Ulm
Quo Vadis FUG ?
The best energy is the one not being used
Reservation of construction areas exclusively for passive houses
Identification of refurbishment areas, going hand in hand with refurbishment of existing building stock
Optimisation of district heating grid– conversion from steam
Independence from imported energies
Operation of planst with Biomass, Waste and (remaining) coal
Use of surplus heat
Supply remaining heat as efficient and environmentally and climate friendly as possible
Almost100% CHP, Modernisation of production parc
