Case study Vicenza
Description Vicenza, 100 000 people, has a large geothermal water reservoir at 68°C around 2 km depth. Heat pumps are implemented to obtain optimum useful heat energy. This DH reduces energy consumption by up to 60%, i.e. 3885 MWh/year.

Production of heating and/or cooling Total heat production in 2013 was 44,6 GWh, produced by:
5,38% (2,4 GWh) geothermal heat (the geothermal exploitation began in mid-2013)
– 27,05% (12,1 GWh) cogeneration
– 67,57% (30,2 GWh) boiler
Others uses
(drinking water, cascade uses…)

geothermal well
the well was already existing
Cost of the MWh sold Prices of the DH service are established by AIM Servizi a Rete, according to a principle of equating of final thermal energy price to the natural gas. Prices of heat sold are also calculated in a different way for residential and for industry and tertiary.
Innovation if any Multi source system
