Retail electricity market

Electricity is supplied to end consumers through the retail market.

A market open to competition

Since the French electricity and natural gas markets were fully opened up to competition on 1 July 2007, consumers have been free to choose their energy supplier.
As a result of deregulation, suppliers other than the incumbent operator, who are known as “alternative” suppliers, entered the retail electricity market, and consumers are now able to choose between two types of offers:

  • market products, with prices set freely by the suppliers;
  • regulated sale tariffs, set by the government and proposed by the incumbent operators (EDF and the 162 local distribution companies)

Consumers whose subscribed capacity is less than or equal to 36 kVa may cancel their contracts and switch to a new product or supplier at any time, at no additional cost and with no interruption in their supply.
Since 1 January 2018, households whose annual taxable income per head is less than €7,700 may be eligible for an energy voucher, which can be used to pay an energy bill, care home charge or to cover the costs of home energy renovation. The energy voucher is the replacement for the previous “social rates” applied to electricity and gas bills. For more information, visit the government website about it.

The market as of 30 June 2018

As of 30 June 2018, 78% of residential and non-residential sites were paying the regulated tariff, with 22% paying market rates (20% with alternative suppliers). Some 36% of electricity used was supplied at the regulated tariff, with 64% supplied at market rates (33% with alternative suppliers).
The non-residential market is much more open (36% of sites pay market rates) than the residential sector (where just 19% of homes pay market rates).

Retail electricity price components  

The retail price (net of tax) of an electricity product, whether at the regulated tariff or the market price, includes:

  • Fixed costs which are identical for all suppliers, such as network access (the price of which is set by CRE);
  • Variable costs which vary between suppliers: electricity generation or supply cost, commercial costs, margin or return taken by the supplier. By optimising these costs, suppliers are able to offer lower prices.

The retail electricity price also includes two contributions and two taxes, which apply in the same way to the bills paid by consumers at the regulated tariff or at market rates:

  • The transmission tariff contribution (“contribution tarifaire d’acheminement” or CTA). This levy finances specific pension entitlements of employees working in regulated sectors covered by the IEG (electricity and gas industries) regime. It is 27.04% of the fixed component of the transmission tariff applied by the electricity transmission system operators.
  • The electricity public service contribution (“contribution au service public de l’électricité” or CSPE). This contribution has been fixed at €22.5/MWh since 1 January 2016, and is paid by all electricity consumers (although the amount paid is capped for large electricity consumers). It finances the costs of electricity provision as a public service;
  • Taxes on end electricity consumption (“taxes sur la consommation finale d’électricité” or TCFE). These taxes, which are determined by French municipalities and administrative départements, are paid by all electricity consumers whose maximum subscribed capacity is less than or equal to 250 kVA. They cover:
    • The municipal tax on end electricity consumption (TCCFE).
    • The département tax on end electricity consumption (TDCFE);
  • VAT, at a rate of:
    • 5.5% on the subscription and CTA, and 20% on the proportional component (including the CSPE and TCFE) for subscribed capacity less than or equal to 36 kVA;
    • 20% on the entire bill, for subscribed capacity greater than 36 kVA.

Fixed or variable market prices

Both the incumbent and alternative suppliers offer products at market prices.
Consumers may choose:

  • Fixed-price offers. The price net of tax remains fixed during the contract period, but taxes and other levies may change. There are various types of fixed-price offers, depending on which billing items remain fixed during the contract period;
  • Variable-price offers. The price changes in line with changes in regulated sale tariffs or other wholesale market indices specified in the contract.

“Green” electricity refers to electricity generated from renewable sources (hydro-electric, wind, solar, geothermal, etc.) or by CHP. Green offers allow consumers to obtain renewable electricity from a certified source.

Regulated sale tariffs


Regulated sale tariffs are governed by Articles L.337-4 to L.337-9 and R. 337-18 et seq. of the French Energy Code. They are available from the incumbent operators: EDF and the 162 local distribution companies.
Since 1 January 2016, in metropolitan France, only consumers who have subscribed capacity lower than or equal to 36 kVA are eligible for regulated tariffs.

How regulated sale tariffs are calculated

Regulated tariffs are established by adding the price of regulated access to incumbent nuclear electricity (known by the acronym “ARENH”), the cost of the electricity supply complement which includes the capacity guarantee, transmission costs and marketing costs, as well as a normal rate of return on investment. This method aims to ensure that these tariffs can be “challenged” by alternative suppliers, i.e. they are able to offer consumers market products at prices equal to or lower than the regulated sale tariff.

Changes to regulated sale tariffs

Since 8 December 2015, CRE has sent the Ministers for Economy and Energy proposals for regulated electricity sale tariffs, along with reasoned arguments. The government then has three months in which to contest the proposals.

How the retail markets work: shared procedures

In practice, the retail markets in electricity and gas work according to rules established by working groups set up by CRE in 2005. These WGs include all of the stakeholders concerned: consumer representatives, suppliers, system operators and the government. Under the aegis of CRE, they have defined common operating procedures for professionals in the industry.
The operating rules (or procedures) between suppliers and system operators in respect of professional or residential clients are laid down in the “customer reference base”, which has been in force since the electricity and natural gas markets were opened up to competition. The reference base is the result of work by two consultation bodies: the Electricity Working Group (GTE) and the Gas Working Group (GTG).
