Monthly publication of the increase/decrease value of CWE Intraday Available Transfer Capacity

Update: starting on the 4th of September, the increase or decrease value of the initial ID ATCs will be published on daily basis.

Dear Market Participants,

Since Business Day 30th of March 2016 the Central West Europe intraday ATC Capacity Calculation process (CWE ID ATC CC) after Flow-Based Market Coupling (FBMC) is in operation. During this process, CWE TSOs reassess the initial ID ATCs, which are left over from the day ahead market coupling. Up to now, the initial ID ATCs were being published on the JAO website (http://www.jao.eu/main).

In order to further enhance transparency levels and better enable market participants to draw up their own statistics on the ID process results, CWE TSOs have set up a new process to also publish the increase or decrease value of the initial ID ATCs. This will be done for the following CWE borders: Belgium-France, Germany-France, Belgium-Netherlands and Germany-Netherlands.

The increase/decrease values will be published once a month on the JAO website, on the second day of the month for the previous month. In addition, the increase/decrease values since go-live will be published retroactively. The first publication that is available on the 2nd of June 2017 will therefore include all increase/decrease values since the 30th of March 2016 until the 31st of May 2017.

Relevant information on the CWE ID ATC after FBMC process is available at JAO at http://www.jao.eu/marketdata/implicitallocation.

Best regards,

CWE Transmission System Operators
