Article 141 U.K. Process responsibility structure

1. When specifying the process responsibility structure, all TSOs of [F1 the GB synchronous area] shall take into account at least the following criteria:

(a) the size and the total inertia, including synthetic inertia, of the synchronous area;

(b) the grid structure and/or network topology; and

(c) the load, generation and HVDC behaviour.

2. By 4 months after entry into force of this Regulation, all TSOs of [F2 the GB synchronous area] shall jointly develop a common proposal regarding the determination of the LFC blocks, which shall comply with the following requirements:

(a) a monitoring area corresponds to or is part of only one LFC area;

(b) a LFC area corresponds to or is part of only one LFC block;

(c) a LFC block corresponds to or is part of only one synchronous area; and

(d) each network element is part of only one monitoring area, only one LFC area and only one LFC block.

3. All TSOs of each monitoring area shall continuously calculate and monitor the real-time active power interchange of the monitoring area.

4. All TSOs of each LFC area shall:

(a) continuously monitor the FRCE of the LFC area;

(b) implement and operate a FRP for the LFC area;

(c) endeavour to fulfil the FRCE target parameters of the LFC area as defined in Article 128; and

(d) have the right to implement one or several of the processes referred to in Article 140(2).

5. All TSOs of each LFC block shall:

(a) endeavour to fulfil the FRCE target parameters of the LFC block as defined in Article 128; and

(b) comply with the FRR dimensioning rules in accordance with Article 157 and the RR dimensioning rules in accordance with Article 160.

6. All TSOs of [F3 the GB synchronous area] shall:

(a) implement and operate a FCP for the synchronous area;

(b) comply with FCR dimensioning rules in accordance with Article 153; and

(c) endeavour to fulfil the frequency quality target parameters in accordance with Article 127.

7. All TSOs of each monitoring area shall specify in the monitoring area operational agreement the allocation of responsibilities between TSOs in the monitoring area for the implementation of the obligation set out in paragraph 3.

8. All TSOs of each LFC area shall specify in the LFC area operational agreement the allocation of responsibilities between TSOs in the LFC area for the implementation of the obligations set out in paragraph 4.

9. All TSOs of each LFC block shall specify in the LFC block operational agreement the allocation of responsibilities between TSOs in the LFC block for the implementation of the obligations set out paragraph 5.

10. All TSOs of [F4 the GB synchronous area] shall specify in the synchronous area operational agreement the allocation of responsibilities between TSOs in the synchronous area for the implementation of the obligations set out in paragraph 6.
