CERN to heat homes in Ferney-Voltaire
ENHANCING THE REGION'S ENERGIES 🌍
SEMOP "Pays de Gex Énergies" is a company responsible for designing and operating a smart grid* in Ferney-Voltaire, in the Ferney Geneva Innovation ZAC.
SEMOP plans to implement an innovative network that will harness waste heat from the world's largest particle accelerator, CERN's Large Hadron Collider (LHC), to provide more than 65% renewable energy to more than 20,000 Ferneys. This initiative will help remove the equivalent of 5,000 tonnes of CO2 from the atmosphere annually.
The pooling of the efforts of two local public companies guarantees the viability of the operation: the Société d'Économie Mixte à Opération Unique (SEMOP) "Pays de Gex Energies" deploys and operates the medium and high temperature network in the municipality of Ferney-Voltaire, while the Société Publique Locale (SPL) Territoire d'Innovation is in charge of the low-temperature network and geothermal probes.

REUSING THE WASTE ENERGY PRODUCED BY CERN 🔥
As a flagship project in terms of ecological transition, this thermal smart grid*, which also includes an electricity component thanks to the development of collective self-consumption of electricity, is a powerful driver for the energy transition of the Pays de Gex, while promoting social equity by offering, in the long term, energy at a lower price than that currently charged in Ferney-Voltaire.
The first objective of this project is to take advantage of the proximity of CERN's shafts to heat existing and future neighbourhoods, by creating district heating networks. The Ferney-Voltaire smart thermal grid is powered by six different energy sources:
✔ Heat recovered from the world's most powerful particle accelerator, CERN's Large Hadron Collider (LHC).
✔ The anergy loop thanks to geothermal energy.
✔ Heat recovered from the future datacenter located in the ZAC Ferney Genève Innovation.
✔ The solar panels installed on the ZAC.
✔ Electricity to power heat pumps.
✔ Natural gas as a back-up and backup source.
This network will provide heating and cooling to residential and business buildings. Each year, it will save the equivalent of 5,000 tonnes of CO2 emissions, using energy recovered from CERN's equipment on our territory. In addition, the buildings' self-consumption of electricity, a gas boiler room and predictive management will complete the system.
💡 To find out more about this ecological initiative, we invite you to listen to Patrice Dunand, the president of Pays de Gex agglo, at the microphone of RadioFrance.
*Smart grids are energy networks that, using state-of-the-art technologies, adjust energy flows between suppliers and consumers. By collecting information on the state of the grid, smart grids help to save energy, among other things.
