| Member state | ITALY |
| 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. |
| Region>City>location | Veneto > Vicenza |
| Installed capacity ( MWth) |
36,7 MWth |
| Installed geothermal capacity | 700 kWth |
| DH length (m) |
19.148 m |
| Inhabitants connected | 211 |
| Operating Temperature of the DH | Water temperature of DH network in delivery pipes: 85 °C – 65 °C |
| Temperature of the geothermal ressource (production – injection) |
68°C |
| Geothermal flow rate |
100 m3/h |
| 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…) |
no |
| Investement for 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 |
