Founded in 2005, Alterna sells both electricity and gas to customers across France.
About Alterna
Created in 2005 by the fusion of local distribution companies (in French: entreprises locales de distribution - ELD) Gaz Electricité de Grenoble and Sorégies, Alterna is one of the latest energy suppliers to appear on the market. Alterna offers are available throughout the French territory, with the exception of the service areas of Gaz Electricité de Grenoble, Sorégies, and of local distribution companies.
Alterna is a group of twenty local distribution companies that have pooled their resources in order to offer service across France. This allows Alterna to rely on a network of locally established suppliers, despite its small size. Currently counting close to 360,000 customers, Alterna seeks to find new local distribution companies to expand its network and ultimately acquire 5-10% of the residential French electricity market. Alterna also offers gas supply thanks to a partnership with Eni.

Our Thoughts on Alterna's Offers
Whether for regular or for green electricity, our thoughts on Alterna are the same: Alterna does not offer the cheapest rates on the market. Likewise, their rates for natural gas, while more competitive, are not the cheapest to be found.
