1.Each TSO shall ensure the availability of at least its FCR obligations agreed between all TSOs of [F1the GB synchronous area in accordance with Articles 153 and 163].
2.All TSOs of [F2the GB synchronous area] shall determine, at least on an annual basis, the size of the K-factor of the synchronous area, taking into account at least the following factors:
(a)the reserve capacity on FCR divided by the maximum steady-state frequency deviation;
(b)the auto-control of generation;
(c)the self-regulation of load, taking into account the contribution in accordance with Articles 27 and 28 of Regulation (EU) 2016/1388;
F3(d). . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
(e)the LFSM and FSM activation in accordance with Articles 13 and 15 of Regulation (EU) 2016/631.
F43.. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
4.An FCR provider shall guarantee the continuous availability of FCR, with the exception of a forced outage of a FCR providing unit, during the period of time in which it is obliged to provide FCR.
5.Each FCR provider shall inform its reserve connecting TSO, as soon as possible, about any changes in the actual availability of its FCR providing unit and/or its FCR providing group, in whole or in part, relevant for the results of prequalification.
6.Each TSO shall ensure, or shall require its FCR providers to ensure that the loss of a FCR providing unit does not endanger the operational security by:
F5(a). . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
(b)excluding the FCR provided by the unit defining the reference incident of the synchronous area from the dimensioning process for [F6the GB synchronous area]; and
(c)replacing the FCR which is made unavailable due to a forced outage or the unavailability of an FCR providing unit or FCR providing group as soon as technically possible and in accordance with the conditions that shall be defined by the reserve connecting TSO.
7.An FCR providing unit or FCR providing group with an energy reservoir that does not limit its capability to provide FCR shall activate its FCR for as long as the frequency deviation persists. For the GB [F7synchronous area], a FCR providing unit or FCR providing group with an energy reservoir that does not limit its capability to provide FCR shall activate its FCR until it activates its FRR or for the period specified in the synchronous area operational agreement.
8.A FCR providing unit or FCR providing group with an energy reservoir that limits its capability to provide FCR shall activate its FCR for as long as the frequency deviation persists, unless its energy reservoir is exhausted in either the positive or negative direction. For the GB [F8synchronous area], a FCR providing unit or FCR providing group with an energy reservoir that limits its capability to provide FCR shall activate its FCR until it activates its FRR or for the period specified in the synchronous area operational agreement.

12.The FCR provider shall specify the limitations of the energy reservoir of its FCR providing units or FCR providing groups in the prequalification process in accordance with Article 155.
[F1013.A FCR provider using FCR providing units or FCR providing group with an energy reservoir that limits their capability to provide FCR shall ensure the recovery of the energy reservoirs in the positive or negative directions for the GB synchronous area, using the methods specified in the synchronous area operational agreement.]
