About us

About us

The raising awareness of dwindling natural resources combined with a growing world population and an increasing need in energy is now shared. Political class, corporates and general public agree on the need for alternative energy solutions.

Altergie is resoluted to accelerate the energy transition to more sustainable supply modes by implementing alternative energy solutions.

Our philosophy is to use solar energy as a vector of sustainable development in local communities.

Altergie core business is to develop and operate sun power facilities in France mostly at utility scale

Our corporate background & evolution

Our activities started in 2009 in the French overseas departments and territories with a pool of private investors. In 2015, after the commissioning of three sun power facilities in Belvezet (Gard) accounting for more than 20 MWc, shareholders divested their interests due to a growing concentration in the sun power sector. Part of the company’s assets both in operating and development phases are retained by the founding chairman another part is sold out.

Altergie Développement is now a fully independent and private firm owned and controlled by its president.
