Cegelec was officially formed in 1989, and as of 2014 the company employs around 22,000 people and operates in 30 countries, with major activity in France, Brazil, Indonesia, the Middle East and Africa.
In 1989 CGE and General Electric Company formed the joint operation GEC-Alstom, and CGEE-Alstom was renamed Cegelec.
On 20 July 2001 Alstom Contracting was subject to a Leveraged Management Buyout supported by Caisse des dépôts et consignations and Charterhouse Capital Partners, and was renamed Cegelec.
After the acquisition, the administration and direction of each company were controlled by Vinci Energies, yet each sub-company maintained their original specializations.
Some of such contracts include management of the electrification of the 18 km long tram line in Rabat, Morocco, in 2008, which officials commissioned to connect the inner and outer bounds of the capital city.
This contract lasted 18 months and resulted in the refinery raising its efficiency and meeting modern safety standards.
List of countries in which Cegelec has been involved in Africa:[21] Beginning in the early 2000s, the Middle East's oil and gas supply entered the world economy, increasing regional GDP by 32% for local involved countries, who then employed offshore companies to assist the management of the new supply.
