In the economic climate that followed the oil shocks, Sidec (Société Industrielle pour le Développement de l’Énergie Charbon) was established at the initiative of the public authorities. Founded by the Charbonnages de France Group, its aim was to help industrial companies reduce the share of hydrocarbons in their energy production by enabling them to benefit from installations optimised in terms of efficiency and environmental performance.
As a result, the first cogeneration plants were developed across around thirty industrial sites (food processing, chemicals, automotive manufacturing, tyres and paper), producing both electricity and heat for use in the production processes of these various industries.
