Switzerland’s uptake of shallow geothermal continues unabated and is not constrained by its natural potential. This sector has enjoyed annual compound growth rates of about 12% per annum for the last 12 years (Figure 1), with a total number of some 80’000 ground source heat pumps systems deployed in Switzerland by the end of 2012 (reference 1). Similarly, the theoretical potential for direct use geothermal and geothermal for power generation is considered to be very large.
2012 saw the maturation and execution of two deep geothermal projects, in Schlattingen (Canton Thurgau) in the north of the country and preparations for a combined heat and power project in the city of St. Gallen (Canton St Gallen) located in the east of the country. The combined heat and power project of the City Utility of St Gallen obtained a CHF 24.1 million geothermal guarantee in case the subsurface development fails to deliver the projected reserves.
