The certified capacities registry, a public document, listing all certified capacities connected to the transmission or distribution systems. RTE describes all characteristics of the capacities, the amount of power certified, and the capacities projected availability (updated);
- NCC initial : NCC as brought to the attention of RTE in the first certification request of an EDC for a given delivery year. It corresponds to the volume of guaranties initially allocated to the capacity operator.
- NCC : Last NC for which a contract was signed with RTE (Certification request or a rebalancing request). It corresponds to the volume of guarantees currently allocated to the capacity operator.
- NCC evolved : Best estimation of NCE as brought to the attention of RTE by the capacity operator. It can differ from the NCC when the operator has made a declaration of changes to the certification parameters, without rebalancing request. Capacity operators whose evolved NCC of an EDC is more than 100 MW away from the NCC are required to declare their evolved NCC.
To this volume, must be added the capacity guarantees corresponding to the contribution of interconnections (these capacities were until 2018 taken into account implicitly via the safety factor) which are already certified (this is the case for all interconnections in 2019, 2020 and 2021)
For the years 2022 and 2023, on November 5, 2020, the interconnections are not yet certified but the contributions of the interconnections, which correspond to the cap for certified interconnection capacities, are published in the rules of the capacity mechanism (Article §B.1.5).
