SWSG – Feasibility of solar assisted district heating networks in the canton of St.Gallen

Solar assisted district heating is widely used in countries as Austria, Germany and Sweden and is booming in Denmark. Heat production costs below 0.05 CHF/kWh where recently reached. With this feasibility study district heating networks of the canton of St. Gallen are analyzed in terms of the feasibility and the cost-benefit ratio of an integration of large solar thermal collector field. A further goal is to make contact between collector manufacturers and network operators as well as to initiate the realization of several large collector fields.

SWSG is supported by the canton of St.Gallen and the Swiss Federal Office of Energy (SFOE).
