Sanofi: the Sisteron plant – pilot energy optimisation site

The Sanofi Group plant in Sisteron manufactures active ingredients for medicines used in various therapeutic fields. This site is in operation 24 hours a day and needs energy continuously all year round. How can the production of refrigeration for industrial purposes – which is essential for the plant’s production purposes – be rendered more reliable, while at the same time optimising resources and reducing energy spending and the environmental impact? The Sanofi Group tasked ENGIE Solution with taking up these major energy challenges for its plant in Sisteron. A high-stakes challenge that was successfully embraced with the help of a single global multi-technical maintenance contract and the application of ENGIE Solutions’ industrial expertise.

Key figures

4 500 tonnes of CO2 emissions avoided every year

15% reduction in energy consumption

2,4 MW refrigeration capacity

1^st facility incorporating high-capacity CO2 refrigerant fluid in the pharmaceutical industry

Towards a greener, less energy-guzzling form of innovative production

To successfully deliver this project, ENGIE Solutions developed a turnkey solution for Sanofi, that involved gauging the site's requirements, building a new facility and providing maintenance and ensuring guaranteed performance for the Sisteron site.
The new production/distribution system implemented at the site is an innovation in the world of chemistry/pharmaceuticals: refrigeration is produced using CO2, in a way that is significantly less polluting and which requires less energy than the refrigerant gases used previously.
