The methodology for determining the total manual frequency restoration reserve need (approximately 1000 MW of mFRR) is given in the Load-Frequency Control Block operational agreement. For a given day, the manual frequency restoration reserve volume to be contracted is the remaining volume to be covered for the day after deducting the volume of manual frequency restoration reserve allocated at the periodic tender (50% of the total requirement of 1,000 MW for 2026), plus any additional manual frequency restoration reserve volumes cancelled by the market participants in the periodic tender following a change of the initial commitments. For a given day, the complementary reserve need is the remaining need to be covered for the day after deducting the volume of complementary reserve allocated at the periodic tender (50% of the total requirement of 500 MW for 2026), plus any additional complementary reserve volumes cancelled by the market participants in the periodic tender following a change of the initial commitments.
The aFRR dimensioning method is described in the RTE Load-Frequency Control Block operational agreement.
The RTE’s need of FCR is established in accordance with the provisions of the ‘Joint Proposal for FCR Dimensioning Rules developed by all continental European TSOs in accordance with Article 153(2) of the SOGL Regulation’. The RTE’s need is fixed for one year and reviewed annually.
How to use the ‘Product type’ filter below:
- FCR and aFRR have the product type ‘STD’,
- mFRR and complementary reserve have the product type ‘SPE0’.
To ensure a balance between supply and demand, RTE contracts power reserve availabilities from reserve providers and balancing service providers.
- Frequency Containment Reserve and Automated Frequency Restoration Reserve are procured respectively through a European day-ahead tender (FCR Cooperation) and a national day-ahead tender. Reserve providers are granted a remuneration according the conditions laid down in the Frequency Ancillary Terms and Conditions. The published price is the marginal price calculated for the quarter hourly interval.
- Tertiary reserve is procured through a tender from balancing service providers. It aims at ensuring a minimum volume of tertiary reserve (upward potential) available in less than 13 min (about 1,000 MW) and a volume of tertiary reserve available in less than 30 min (about 500 MW). From 2026, periodic calls for tenders (AOP) will replace annual calls for tenders. For 2026, tenders will be quarterly (the first AOP tender covers the period from 1 January to 31 March 2026, with the AOP closing on November 22, 2025). A daily tender complement the periodic tender, by contracting reserves in D-1 for day D. Balancing service providers are granted a capacity remuneration, calculated on the procured volume and the marginal price of the corresponding tenders. The published price is the marginal price calculated for the quarter hourly interval since January 1, 2025.
How to use the ‘Product type’ filter below:
- FCR and aFRR have the product type ‘STD’,
- mFRR and complementary reserve have the product type ‘SPE0’.
Margins represent a volume of capacity available for RTE to be used to cope with generation or consumption contingency consequences. They are thus one of the essential components of system control under safe operating
RTE proposes on this web page to display the available upward and downward margins, required margins (risk 1%) as well as France’s forecasted imbalance.
Margins are calculated from D-1 and updated throughout the day, based on the best hypothesis at our disposal.
The volume of "mFRR" and "specific RR" corresponds to the aggregation of specific balancing energy bids submitted on the balancing mechanism.
The volume of “RR standard" and “RR standard restricted" corresponds respectively to the aggregated volume of RR standard bids shared on the TERRE platform and the aggregated volume of unavailable RR standard bids.
The information message (known as an alert message in the MA-RE Terms and Conditions) is sent as of D-1 when the usable volume of capacity available on the balancing mechanism taking into account the forecast imbalance is less than the required margin. The aim of this message is to inform BRPs of potential imbalance at peak demand so that they may take the required actions and balancing service providers, so that they may submit additional offers to RTE.
The message of potential need for activation of additional balancing bids (known as downgraded mode in the MA-RE Terms and Conditions) is transmitted based on the same criterion as the previous information message. This message aims to inform balancing service providers, as close as possible to the operational window, of the potential activation of their additional bids and to inform balance responsible parties of a potential impact on the imbalance settlement price of the activation of more expensive bids.
