The city of Pau has entrusted Pau Béarn Pyrénées Energies Services, a subsidiary of Engie Solutions and Banque des Territoires, with the design, development and operation of a district heating network comprising 174 substations in a grid spanning the city of Pau. Eventually, 75% of this heating network will be supplied by waste and wood.
Key figures of the project:
- 45 km of network
- 200 buildings connected
- 76% of heating needs met through local and renewable energy
- 24,000 metric ton reduction in CO2 per year
- €60M investment with financial support from Ademe, the Regional Council of Nouvelle-Aquitaine and the European Union with the European Regional Development Fund
Why Distech Controls technology?
For this type of installation, Distech Controls offers a comprehensive substation package that is fully integrated into and compatible with the COFELY VISION management system — a Big Data monitoring application for optimizing maintenance.
The Distech Controls solution has a major advantage: local communication between the digital tool (tablet) used by the maintenance technician and the ECLYPSE controllers, all through a connected Wi-Fi antenna. This means consistent information that can be accessed quickly!
The connected ECLYPSE controller for HVAC equipment (ECY-303) was a deciding factor for the installer: a compact multi-protocol controller with integrated BACnet/IP, Modbus/IP and Modbus RS485, all connected through a 4G modem and secure VPN loop.
