CHAPTER 1

All TSOs involved in the exchange of FCR within a 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 a 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. A TSO shall not share FCR with other TSOs of its synchronous area to fulfil its FCR obligation and to reduce the total amount of FCR of the synchronous area in accordance with Article 153. All TSOs of a synchronous area shall define in the synchronous area operational agreement the roles and responsibilities of the reserve connecting TSO, the reserve receiving TSO and the affected TSO for the exchange of FRR and/or RR. Where an exchange of FRR/RR takes place, the reserve connecting TSO and reserve receiving TSO shall notify that exchange pursuant to the notification requirements in Article 150. The reserve connecting and reserve receiving TSOs participating in the exchange of FRR/RR shall specify in a FRR or RR exchange agreement their roles and responsibilities, including: the responsibility of the reserve instructing TSO for the reserve capacity on FRR and RR subject to the exchange of FRR/RR; the amount of the reserve capacity on FRR and RR subject to the exchange of FRR/RR; the implementation of the cross-border FRR/RR activation process in accordance with Articles 147 and 148; FRR/RR technical minimum requirements related to the cross-border FRR/RR activation process where the reserve connecting TSO is not the reserve instructing TSO; the implementation of the FRR/RR prequalification for the reserve capacity on FRR and RR subject to exchange in accordance with Articles 159 and 162; the responsibility to monitor the fulfilment of the FRR/RR technical requirements and FRR/RR availability requirements for the reserve capacity on FRR and RR subject to exchange in accordance with Articles 158(5) and 161(5); and procedures to ensure that the exchange of FRR/RR does not lead to power flows which violate the operational security limits. Any reserve connecting TSO, reserve receiving TSO or affected TSO involved in the exchange of FRR or RR may refuse the exchange referred to in paragraph 2 where it would result in power flows that violate the operational security limits when activating the reserve capacity on FRR and RR subject to the exchange of FRR or RR. The concerned TSOs shall ensure that exchange of FRR/RR does not prevent any TSO from complying with the reserve requirements established in the FRR or RR dimensioning rules in Articles 157 and 160. All TSOs of a LFC block shall specify in the LFC block operational agreement the roles and responsibilities of the reserve connecting TSO, the reserve receiving TSO and the affected TSO for the exchange of FRR and/or RR with TSOs of other LFC blocks. All TSOs of a synchronous area shall specify in the synchronous area operational agreement the roles and responsibilities of the control capability providing TSO, the control capability receiving TSO and the affected TSO for sharing FRR/RR. Where FRR/RR sharing takes place, the control capability providing TSO and control capability receiving TSO shall notify that sharing pursuant to the notification requirements in Article 150. The control capability receiving TSO and the control capability providing TSO participating in the sharing of FRR/RR shall specify in a FRR or RR sharing agreement their roles and responsibilities, including: the amount of reserve capacity on FRR and RR subject to the sharing of FRR/RR; the implementation of the cross-border FRR/RR activation process in accordance with Articles 147 and 148; procedures to ensure that the activation of the reserve capacity on FRR and RR subject to the sharing of FRR/RR does not lead to power flows that violate the operational security limits. Any control capability providing TSO, control capability receiving TSO or affected TSO involved in the sharing of FRR/RR may refuse sharing of FRR/RR where it would result in power flows that violate the operational security limits when activating the reserve capacity on FRR and RR subject to the sharing of FRR/RR. In case of sharing of FRR/RR, the control capability providing TSO shall make available to the control capability receiving TSO a share of its own reserve capacity on FRR and RR required to comply with its reserve requirements for FRR and/or RR resulting from the FRR/RR dimensioning rules in Articles 157 and 160. The control capability providing TSO can be either: the reserve instructing TSO for the reserve capacity on FRR and RR subject to the sharing of FRR/RR; or the TSO having access to its reserve capacity on FRR and RR subject to the sharing of FRR/RR through an implemented cross-border FRR/RR activation process as part of an FRR/RR exchange agreement. Each control capability receiving TSO shall be responsible for coping with incidents and imbalances in case the reserve capacity on FRR and RR subject to the sharing of FRR/RR are unavailable due to: restrictions to provide frequency restoration or adjust the control program related to operational security; and partial or full usage of the reserve capacity on FRR and RR by the control capability providing TSO. All TSOs of a LFC block shall specify in the LFC block operational agreement their roles and responsibilities of the control capability providing TSO, the control capability receiving TSO and the affected TSO for the sharing of FRR and RR with TSOs of other LFC blocks. All TSOs in a synchronous area consisting of more than one LFC block involved in the exchange of FRR within the synchronous area shall comply with the requirements and limits for the exchange of FRR set out in the Table of Annex VII. Each TSO of a LFC block shall have the right to share FRR with other LFC blocks of its synchronous area within the limits set by the FRR dimensioning rules in Article 157(1) and in accordance with Article 166. All TSOs in a synchronous area consisting of more than one LFC block involved in the exchange of RR within the synchronous area shall comply with the requirements and limits for the exchange of RR set out in the Table of Annex VIII. Each TSO of a LFC block shall have the right to share RR with other LFC blocks of the same synchronous area within the limits set by the RR dimensioning rules in Article 160(4) and (5) and in accordance with Article 166.
