Network Optimisation – Digitalisation

  • A supervision ICT platform for detection and diagnosis of faults in DH substations
  • Visualisation tools for expert and non-expert users
  • Smart DH network controller to balance supply and demand and minimise return temperature (i.e. STORM controller)

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.


The TEMPO project develops technical innovations that enables district heating networks to operate at lower temperatures. By decreasing the temperature, it reduces heat losses and allows a higher share of renewable and excess heat to be used as heat sources.


The TEMPO project consortium gathers eleven partners in six European countries. It includes research companies, industrial companies, district heating operators, a university, and an industry association.

Low temperature district heating

Today’s district heating systems are made mainly for fossil fuels that easily generates high temperatures. To create tomorrow’s district heating systems, adapted to a sustainable energy system, we need to use non-fossil heat supply such as renewable and excess heat that are generally characterised by lower temperatures.
