Open Energy

We offer new forms of electricity supply and management to our clients, who are the main actors of the new energy model. Our solutions are based on clean technologies


Opengy stands for “open energy”, open, transparent, and accessible energy.

We want to actively participate in the energy transition process in which the electricity sector is immersed. After operating in the same way for more than a century, a profound and rapid change is taking place. We are moving from a centralised, closed, oligopolistic and fossil-based system towards a decentralised, open, clean, and digital one. This is possible thanks to the emergence of new technologies (such as solar photovoltaic or batteries), new actors (such as Opengy), new solutions (such as self-consumption) and new services (such as PPAs).

Our goal is to help our clients make this transition in an optimal way and benefit from the change of the energy model.

We collaborate with Blacksalt, an Asset Management firm focused on the renewable energy sector, mainly solar PV technology, that fosters economic growth, social impact, environmental sustainability, and long-term value generation.

Opengy is part of the Enertis Group.
