Created in 2005 by the fusion of local distribution companies (entreprises locales de distribution - ELD) Gaz Electricité de Grenoble and Sorégies, Alterna is an alternative energy supplier operating throughout the French territory.
About Alterna
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.

Alterna gas offer
Alterna offers a single natural gas offer: Idéa Gaz. Its price can be revised once a year and the terms of payment and customer service are the same as for electricity.
However, it is difficult to compare Alterna's gas prices
with those of other market offers because the supplier has defined its price according to the municipalities and not according to the tariff zones. To know the price applied at your home requires a detailed quotation from Alterna.
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.
