From Aldro to Plenitude

The company's roots in Spain go back to Aldro Energía, founded in Santander in 2014. In 2021, the global energy leader Eni acquired the business as part of its transition toward sustainable energy.

Rebranded as Plenitude, the company now integrates retail energy sales with renewable generation and EV charging solutions across Europe, serving over 10 million customers globally.

In 2026, Plenitude remains headquartered in Santander, maintaining strong local ties while benefiting from the massive scale and financial stability of the Eni group.
