Engie's Regulated Tariffs

As the historic natural gas supplier, Engie is the only supplier to offer regulated rates for natural gas, which are still offered under the name GDF Suez. Regulated tariffs are fixed by public authorities, and change every month.

Engie's Regulated Rates

Good to Know!Gas in France is measured in kWh.

Engie's regulated tariffs change slightly depending on your region (zone tarifaire). There are 6 tarif regions in France (Paris is Zone 2). The price differences reflect the difference in transportation costs to that particular region.

While most residential gas customers in France purchase the regulated tariff from GDF Suez/Engie, many alternate suppliers offer reduced rates that are based off the regulated tariff, and guarantee savings.

A response to Direct Energie's 100% Online electricity plan, Happ-e proposes a 7% la 1ère année seulement% discount on the pre-tax EDF regulated tariff for electricity. This discount is guaranteed for two years, making it one of the cheapest electricity offers on the market. If you are comfortable with 100% online customer service and only need to worry about paying an electricity bill (i.e. you don't use natural gas as well), Happ-e is definitely worth considering.

Fixed Prices

The Engie Gaz Fixe plans feature fixed prices for 1 to 3 years on the price for electricity and gas (before taxes). Note that the price of gas doesn't include taxes, which could change over the year. Fixed price plans can be cancelled at any time without penalty. Plans are usually automatically renewed once they reach their expiration date, but customers are notified at least one month in advance. To help its customers make additional savings, Engie offers an energy conservation service, called Cap EcoConso.

Engie also offers a fixed price plan in which the prices can be reduced once a year if the regulated tariffs drop (Gaz Ajust, Duo Ajust).

Green Energy Plans

As of 2018, all of Engie's electricity plans are green plans and feature fixed prices on the per kWh price of electricity and/or gas. Green electricity is sourced from hydroelectric plants that Engie owns in France.

Other Types of Plans Offered by Engie

Customers that have smart meters (known as Linky meters) can sign up for a peak/off-peak plan that features a 30% discount on electricity on evenings and weekends (Elec Weekend). This is a two-year plan, but it can be cancelled at any moment. Prices otherwise follow the regulated tariffs.

About Engie

Engie (formerly GDF Suez, formerly Gaz de France) was formed in 2008 by the merger of Gaz de France and Suez, and its origins date back to the 19th century with the creation of the Universal Suez Canal Company. Gaz de France was created in 1946, when the French government nationalized the assets of private gas and power companies in France. The company was privatized in 2006 in preparation for its merger with Suez in 2008. When it was formed, GDF Suez became the second-largest utlity in the world. As of December 2014 the French government held one-third of GDF-Suez.

In April, 2015, GDF Suez rebranded as Engie, in recognition of its goal of becoming a leader in the energy transition.

How to Open an Engie Account

If you are moving to a home with natural gas service, you will need to open an account for gas supply in your name. For this you have two options: you can choose to open an account with Engie for the GDF Suez regulated tariffs, or you can compare gas offers and choose a plan with an alternate supplier.

Regardless of which supplier you choose, the process for opening a natural gas account is the same:

  • You need to have the following information in order to open an energy account with Engie
  • Your contact information: name, e-mail address, phone number
  • The address of your new accommodation. Don't forget the floor and apartment number if it is a flat (e.g. third floor, door on the left)
  • The name of the previous occupant
  • Your banking information (RIB) (IBAN and BIC, if you choose automatic payment)

How to Cancel a Plan With Engie

Whether you have signed up for the GDF regulated tariffs or for a competitive energy plan with Engie, you can cancel your plan at any moment. Energy suppliers in France are not allowed to charge early cancellation fees for energy plans, so changing suppliers comes with very little risk. If you decide to switch to another energy supplier, your new supplier will take care of notifying Engie and ending your plan on your behalf.

If you need to close your Engie account because you are moving, you can cancel over the phone, online (through your online Engie account), or by post. If cancelling via post, we recommend sending a letter by recommended post (lettre recommandée avec avis de reception), as this will enable you to know when Engie has received your notice.

Save time by sending your cancellation letter online with Selectra's cancellation service (in French). Generate a free letter template in minutes, and let Selectra take care of cancelling your Engie contract for you.

When cancelling your plan with Engie, don't forget to include the following:

  • Your full name
  • Your account number
  • The final date for service (your moving out date)
  • Your contact information, including email address and a forwarding address if possible
