Article 163 Exchange of FCR within a synchronous area

All TSOs involved in the exchange of FCR within F1the GB synchronous area shall comply with the requirements set out in paragraphs 2 to 9. The exchange of FCR implies a transfer of a FCR obligation from the reserve receiving TSO to the reserve connecting TSO for the corresponding reserve capacity on FCR.

All TSOs involved in the exchange of FCR within F2the GB synchronous area shall respect the limits and requirements for the exchange of FCR within the synchronous area specified in the Table of Annex VI.

In case of exchange of FCR, the reserve connecting TSO and reserve receiving TSO shall notify it in accordance with Article 150.

Any reserve connecting TSO, reserve receiving TSO or affected TSO involved in the exchange of FCR may refuse the exchange of FCR where it would result in power flows that violate the operational security limits when activating the reserve capacity on FCR subject to the exchange of FCR.

Each affected TSO shall verify that its reliability margin, established in accordance with Article 22 of Regulation (EU) 2015/1222, is sufficient to accommodate the power flows resulting from the activation of the reserve capacity on FCR subject to the exchange of FCR.

All TSOs of a LFC area shall adjust the parameters of their FRCE calculation to account for the exchange of FCR.

The reserve connecting TSO shall be responsible for the requirements referred to in Articles 154 and 156 as regards the reserve capacity on FCR subject to the exchange of FCR.

The FCR providing unit or group shall be responsible towards its reserve connecting TSO for FCR activation.

The concerned TSOs shall ensure that exchange of FCR does not prevent any TSO from fulfilling the reserve requirements in Article 156.
