Italian energy giant Eni has sold a 20% stake in its retail and renewables arm, Plenitude, to U.S. alternative investment firm Ares Management Corp. for approximately €2 billion ($2.3 billion).
The deal is part of Eni’s long-term strategy to form strategic partnerships to scale its clean energy businesses. It follows a previous 10% sale to Swiss investment fund Energy Infrastructure Partners.
“Plenitude is an established leader in energy transition, with a differentiated business model and an outstanding track record,” said Stefano Questa, co-head of European Alternative Credit at Ares.

The transaction gives Plenitude an equity value of €10 billion, which rises above €12 billion when including debt. The company operates in more than 15 countries, integrating over 4 GW of renewable energy generation with retail power and gas services. Plenitude also manages 21,500 EV charging points and serves more than 10 million customers.
