Greater Paris: Clemessy designs and builds the monitoring and control equipment for the Thermal Smart Grid of the Plateau de Saclay


In charge of developing the Plateau de Saclay as an international research and innovation centre, the Paris Saclay Local Planning and Development Agency (EPAPS) has signed a Design, Building, Operation and Maintenance (DBOM) contract with the IDEX - EGIS consortium for a period of seven years. These two companies have undertaken to create an urban heating and cooling network on two joint development zones (ZAC) and have chosen Clemessy to design and build the monitoring and control equipment for the Thermal Smart Grid which will control all the installations implemented on the two ZACs.

Each ZAC therefore has two geothermal boreholes (i.e. a doublet) made in the Albian groundwater table (approximately 30°C). The new thermal network proposed by the consortium will be fully incorporated into the future Paris Saclay Smart Energy Programme (led by the EPAPS).

The monitoring & control system which Clemessy has to design and build must allow all the [...]
