Project: Modernisation of the district heating system (2010-2014)
The Lodi district heating system has been operating since 2004: although it was originally studied to supply heat to a new district, it was then redesigned to cover the heat demand of the south-west part of the city. Even though recently built, the system operators quickly recognised the need to adapt to the constantly changing energy landscape through increased efficiency as well as integration of renewable energy sources.
The modernisation programme was implemented in several steps (mainly from 2011 to 2013) with the common aim of increasing both efficiency and sustainability, including:
An agreement with a group of local entrepreneurs to recover the heat from their biomass CHP located in a farm 2 km from Lodi
Construction of a thermal storage system
Demand Side Management of substations, through remote control system, continuously changing according to the season the settings of substations
