The interwar period
The First World War strongly weakened SME. Because of a lack of reserves, harsh restriction plans and financial contributions to the war effort, SME could not avoid being taken over by its supplier-competitor EELM in September 1922.
It is in terms of gas production and distribution that the interwar period brought the most changes: in 1935, the Government asked SBM to stop its gas activity.
Street lighting became electric and CIG (Compagnie Industrielle du Gaz) created its new subsidiary: SMG (Société Monégasque du Gaz). On December 23rd, 1936, a 30 year concession was given to SMG by the Prince of Monaco Louis II.
Monaco's whole energy production was then ensured by subsidiaries of French companies.
