The city of Dobbiaco (3,283 inhabitants, 2010) is located 1.256 m above sea level, in the Pusteria Valley in the northern Italian region of Trentino Alto-Adige. It was awarded by the Italian Environment League the title of “Renewable Town” both in 2009 and 2011, and also included in the Res Champions League of 2011.
In terms of electricity production, exceptional results have been obtained thanks to solar PV panels with an installed capacity of 1,590 kW and a 1,783 kW mini-hydro power plant whose production capacity exceeds the electric needs of the families of Dobbiaco.
There are also 1.350 square meters of solar thermal collectors installed as well as a district heating network connected to two installations. One is an 18 MW thermal biomass plant and the other one is a 132 kW biogas facility. Together they can easily produce more energy than the heating needs of Dobbiaco. The biomass district heating plant opened in 1995 and it is able to also satisfy the heat demand of the neighboring town of San Candido. The biomass used in this plant is composed of locally sourced wood chips derived from pruning residues, bark residues, wood waste from sawmill and various factories. Thanks to this combination of technologies Dobbiaco produces more electricity and thermal energy than that consumed by households.
