Abstract

Turkey is one of the few countries that has almost all possible applications of geothermal energy. Geothermal district heating has a
relatively short history (since 1987) compared to other direct utilization but plays important economic, social and environmental roles
in some towns. There are 18 geothermal district heating systems (GDHS), mainly in the Aegean region with resource temperatures
between 57–145C. Current heating capacities of those systems are in the range of 570 to 37500 Residence Equivalent (RE, 1 RE=
100 m2 heated area). This paper evaluates each GDHS on their technical characteristics, then gives details about three GDHS and
compares the economics of district heating applications based on alternative fuel prices.
