Optimised control strategy for solar district heating in Italy

In March 2017, Linea Reti e Impianti, the public utility based in this city of 45,000, started buying heat produced by a 192 m² solar thermal installation. The system is owned by Sporting Lodi, a public-private partnership that operates the local sports centre, which includes a swimming pool (see photo). Marco Calderoni, a researcher working at the Politecnico di Milano, and his colleagues have recently suggested using a new approach to reduce the supply temperature in the solar circuit to increase performance. This article is based on a presentation given by Calderoni during the 5th International Solar District Heating Conference in Graz in April.

Italy: Solar District Heating Shows Few Installations but Good Prospects

Submitted by Baerbel Epp on November 11, 2017
Ambiente ItaliaSubstantial solar resources and a generous incentive scheme called Conto Termico 2.0: Perfect conditions, it seems, for the widespread use of solar district heating. But barriers such as a low gas price and the concentration of district heating in a small part of Italy have so far limited deployment to a few installed systems. The map shows the three existing SDH plants in Varese, Sansicario and Lodi (red circles). A fourth with a gross area of about 600 m² is expected to come online in 2020 to feed heat into Turin’s district network operated by the Iren Group utility (yellow cirle).
