Who is Plenitude ?
Plenitude is an Italian energy supplier, part of the international Eni group. In October 2024, Eni rebranded as Plenitude. The company operates in 15 countries and serves about 10 million customers across Europe, including nearly 1 million in France, making it the fourth-largest energy supplier in the French market.
Plenitude’s origins date back to 1926 with the foundation of AGIP in Italy. Eni, established in 1953, initially aimed to ensure Italy’s energy supply during its post-war economic development. Plenitude was introduced to the French energy market notably through Altergaz, acquired by Eni in 2012.
The company’s activities are focused on the production and sale of electricity and gas, with increasing emphasis on renewable energies. Plenitude develops and operates solar parks in France and other regions, and has projects in agrivoltaics. It also deploys photovoltaic solutions and manages a European network of 20,000 electric vehicle charging stations.
In 2025, Plenitude employed more than 380 people in France and counted around 1 million French customers. The main shareholder is Eni, alongside Ares Management and Energy Infrastructure Partners. Plenitude is not publicly listed and was not state-owned as of 2026.
