What is the public transmission system access tariff (TURPE)?
The main principles
The financial resources required for system operators to carry out their public service missions are obtained mainly through the public transmission system access tariff (TURPE).
The TURPE includes two tariffs:
-
sites connected to the public distribution system pay the TURPE HV-A-LV,
-
sites connected to the public transmission system (including distribution system operators) pay the TURPE HV-B.
The TURPE, its principles and methods are set by decision of the energy regulator, the CRE, following a consultation process involving system operators and all users.
Its objective is to guarantee good coverage of the costs incurred by electricity system operators, provided these costs correspond to those of an efficient system operator.
The tariff is based on four main principles:
1. Postage stamp principle:
Pricing is independent of the distance travelled by the power between the site where it was generated and the site where it was consumed.
2. Tariff equalisation principle:
The same tariffs for system access applies equally across the territory
3. Non-discrimination principle:
The tariff reflects the costs incurred by each category of users regardless of their final use of electricity
4. Principle of hourly/seasonal adjustments:
The cost of the energy part varies according to the seasons, days and hours of use of the Public Transmission System.
In practice, TURPE HV-B is now RTE’s main financial resource, accounting for 80 % of its revenue.
It covers expenditure related to investments financed by RTE and operating costs related to all of its tasks of operating the public electricity transmission system and the power system.
Period of application of the tariff
The general rules for the application of the tariff, its structure and its level are fixed by the CRE for a period of 4 years. However, an adjustment of the level is made every year on the 1st of August. Within a tariff period, this annual adjustment is likely to modify the tariff coefficients, upward or downward, in a limited way, i.e.: the amounts charged to customers for each type of use.
The TURPE HV-B is set up to ensure RTE a forecast authorised revenue trajectory covering all of its expenses over this period. TURPE 7 HV-B applies from 1 August 2025 for a period of 4 years and will be updated annually on 1 August of each year.
Entry into force of TURPE 7
Further to the CRE deliberation no. 2025-77 of 13 March 2025, a new tariff for the use of public electricity transmission systems, TURPE 7 HV-B, will be in effect for a period of 4 years from 1 August 2025.
The most significant changes to TURPE 7 as of 1 August 2025 are as follows:
- Evolution in the pricing of reactive energy generated by DSOs connected to the grid
The reactive energy pricing for distributors is changing:
- The high voltage overshoot pricing coefficients have been increased to make this pricing more representative of the costs incurred on the public transport system;
- Change in the high voltage zone pricing to more effectively target delivery point substations which most contribute to high voltage stress and to incentivize the activation of existing levers.
The pricing of absorbed reactive energy (low voltage) remains unchanged.
- Overriding of exceedances for HV-A capacitor operations.
The charge for HV-A capacitors exceedance will be partially overridden depending on the voltage zone and the type of operation.
- Renewal of the TURPE 6 tariff structure
The method applied for the TURPE 6 tariff is renewed, with improvements made in terms of the consideration of injection points of the grid, in order to render it more robust to evolutions in the system.
The tariff grids have little change in their structure between TURPE 6 and TURPE 7.
There will be further developments to TURPE 7 after August 1, 2025:
- Introduction of a transitional optional tariff component for generation-consumption sites
TURPE 7 introduces a new optional tariff for storage units with the aim of both:
- enabling the deployment of flexibilities offered by users with a symmetrical consumption and generation capacity for the benefit of the system
- and allowing a better reflection of the costs generated by these users.
This component will be applicable from 1 August 2026.
- Change in the setting of peak and off-peak hours
The off-peak hours of all customers connected to the electricity transmission system will be seasonally adjusted, with a generalised setting of off-peak hours on summer afternoons from 1 January 2027.
- New schedule for the Nouvelle-Aquitaine and Occitanie regions
Due to the strong expansion of photovoltaic generation in these two regions, the setting of peak and off-peak hours will differ from the rest of the territory, from 1 January 2027
I am an RTE customer and wish to learn more about TURPE and the tariff currently in effect
The current tariff schedule (as of 1 August 2025) is defined by the 13 March 2025 CRE deliberation. The tariff coefficients applicable as of 1 August 2025 are detailed in the tariff lists available to you in the Library - Understanding the bill.
To learn more, RTE has published the information elements concerning the public transmission system access tariff (TURPE 7 currently in force – examples based on the tariff in force from 1 August 2025):
The TURPE allows the invoice for the transmission system access contract (CART) to be established for RTE customers. For more information:
Digital services available to RTE customers
- to guide customers in their choice of subscriptions, a tariff optimisation Consultation service (optimised Tariff Version and Subscribed Powers) calculated on the basis of past consumptions is available in My Services – CART Management category.
- to track potential reactive energy overruns, a reactive energy overrun notification service is available, in My Services – Notifications category, replacing the Tan Phi overrun notification service.
- In addition, the Subscribed Power Overruns Notification service, accessible to sites with IP-based metering, helps control their subscribed power overruns. Find this service in the My Services tab – Notifications category
As the service is private, you need an account on the RTE’s Service Portal linked to a customer company, (request access from the Service Portal administrator of the company).
