[CWE Flow-Based Market Coupling] Announcement on RTE’s go-live for 70% fulfillment tools in line with CEP
Dear Market Parties,
Since 01.01.2020, in the context of CWE (Central West Europe) Capacity Calculation process, a parallel run relative to the implementation of the minimum 70% capacity requirement stemming from the Clean Energy Package has taken place. This parallel run has been used for local testing of processes and tools. For RTE, one key element is the capacity validation tool that would assess the availability of remedial actions with a view to delivering the 70% minimum capacity for French critical network elements, while ensuring operational security.
With this message RTE intends to inform you about the successful development and stabilization of its CWE validation tool. Nevertheless, the public health measures in force since the end of October in France (lockdown), did not allow RTE’s network operators to benefit from a proper transition and a complete training on the final version of such new processes and tool. Training sessions were held in degraded mode and several individual sessions had to be rescheduled to properly ensure the transfer of knowledge
The target of advanced hands-on technical training per operator in terms of Business Days, in order to ensure a robust go-live of the CEP 70% threshold tool while ensuring operational security, will be reached at the beginning of February 2021. Consequently, the technical solution that would enable RTE to ensure the levels prescribed in Article 16(8) of Regulation (EU) 2019/943 in CWE Capacity Calculation, shall be applied starting from a Delivery Day within the following go-live window: 3rd February to 17th February 2021. A dedicated communication on the exact date will be published at least one week before the deadline.
RTE’s approach for applying the 70% minimum capacity requirement is based on a static value of minRAM Factor * in order to provide more visibility and stability to external stakeholders. The minRAM Factor applied to the French CNECs from the GoLive to the end of the first quarter of 2021 is enclosed in the Excel file.
The values have been determined, based on the monitoring of the available margin for cross-zonal exchanges (MACZT) in line with the ACER recommendation. The average MNCC monitored in the first quarter 2020 has been deduced from the 70% requirement for each CNEC in order to obtain the minRAM Factor. In addition the minRAM Factor has been capped to 70%. Should newly CNECs are introduced in the first quarter 2021 (e.g. never been monitored during the first quarter of 2020), the minRAM Factor value on those CNECs will be set to 70%.
RTE is fully engaged into delivering high levels of capacity available for cross-border trade within all its frontiers. Indeed, the French CNECs currently limit cross-border exchanges within the CWE region in a low percentage of timestamps. We are convinced that the delivery of the aforementioned tool could enable market participants to capture even more value from the French network from February onwards.
We trust to have informed you sufficiently.
Best regards,
RTE
* : The CEP 70% capacity threshold applies on the Margin Available for Cross-Zonal Trade (MACZT) as defined in ACER Recommendation N°01-2019. This MACZT has a different definition than the Remaining Available Margin (RAM) as historically used in CWE.
MACZT = MCCC (e.g. RAM) + MNCC, with MNCC the share of capacity of a CNEC used for cross-zonal trade on bidding-zone borders outside the considered coordination area. Therefore reaching CEP 70% threshold implies taking into consideration the MNCC.
