Brescia: Existing high temperature district heating network

The A2A pilot project involves part of the Brescia district heating network in a low building density area consisting mainly of terraced houses and some apartment blocks.
The existing network is heated by a waste-to-energy plant (~50% coverage), residual heat from industry and CHP, and peak-load gas boilers. The A2A network in Brescia started operating in the ‘70s, and currently operates at temperature levels of 120/60°C.

Nurnberg region: New rural district heating network

A new network in the Nurnberg region (Germany) will supply heat to a less dense area of new buildings, heated by residual heat of a biogas plant and biogas CHPs. Solution package 2 will be demonstrated at this demo site to reduce temperatures and so open up the possibility to integrate a renewable energy source at a later stage.
