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.

RTE informs its customers of the main changes in the tariff. To learn more about TURPE 7, its main principles and developments, you can visit the page Understanding the public transmission system access tariff (TURPE) where you will find:

• explanatory notes on TURPE 7 for Consumers/Generators and Distributors;
• TURPE 7 tariff lists

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 1 August 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 1, 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.
