Location
Description
The city of Brescia in northern Italy is part of the PITAGORAS project, which aims to develop highly replicable, cost-effective and high energy-efficient large-scale energy generation systems that will allow the sustainable urban planning of very-low-energy city districts. The project’s concept for waste heat recovery system is demonstrated in a real-scale pilot plant.
Demo Site Expected Impact
During the winter period, the pilot plant produces district heat (10 MWh), which is delivered via the local district heating network. During the summer season, the pilot plant uses the waste heat to produce around 1.8 MWel of electricity through an Organic Rankine Cycle. The set temperature of heat into the district heating network is 107 °C.
Compared to reference systems, this amounts to a reduction of 39 057 MWh/yr of primary energy demand and a reduction of 7220 tonnes of CO2/yr thanks to the low primary energy (0 kWh of primary energy for every kWh of final energy) and the CO2 factor (0 g CO2/kWh).

Buildings and energy
The implemented solutions include:
Energy systems integration
- District heating and cooling
- Polygeneration
- Waste heat recovery
- Waste-to-energy
The investment cost for the intervention was a total of EUR 12 million, with EUR 2.5 million as funding from the European Union. The revenues are EUR 400 000 for the electricity fed into the grid and EUR 500 000 for the delivered heating energy, resulting in a return on investment of 12 years.
