Article 22 U.K. Categories of remedial actions

1. Each TSO shall use the following categories of remedial actions:

(a) modify the duration of a planned outage or return to service transmission system elements to achieve the operational availability of those transmission system elements;

(b) actively impact power flows by means of:

(i)

tap changes of the power transformers;

(ii)

tap changes of the phase-shifting transformers;

(iii)

modifying topologies;

(c) control voltage and manage reactive power by means of:

(i)

tap changes of the power transformers;

(ii)

switching of the capacitors and reactors;

(iii)

switching of the power-electronics-based devices used for voltage and reactive power management;

(iv)

instructing transmission-connected DSOs and significant grid users to block automatic voltage and reactive power control of transformers or to activate on their facilities the remedial actions set out in points (i) to (iii) if voltage deterioration jeopardises operational security or threatens to lead to a voltage collapse in a transmission system;

(v)

requesting the change of reactive power output or voltage setpoint of the transmission-connected synchronous power generating modules;

(vi)

requesting the change of reactive power output of the converters of transmission-connected non-synchronous power generating modules;

(d) re-calculate day-ahead and intraday cross-zonal capacities F1 ...;

(e) redispatch transmission or distribution-connected system users within the TSO's control area F2 ...;

(f) countertrade between two or more bidding zones;

(g) adjust active power flows through HVDC systems;

(h) activate frequency deviation management procedures;

(i) curtail, pursuant to [F3 Article 16(2) of Regulation (EU) 2019/943 as that provision applied in EU law immediately before IP completion day], the already allocated cross-zonal capacity in an emergency situation where using that capacity endangers operational security, all TSOs at a given interconnector agree to such adjustment, and re-dispatching or countertrading is not possible; and

(j) where applicable, include the normal or alert state, manually controlled load-shedding.

2. Where necessary and justified in order to maintain operational security, each TSO may prepare and activate additional remedial actions. The TSO shall report and justify those instances to the F4 ... regulatory authority and, where applicable, the [F5 Secretary of State], at least once every year, after the activation of the additional remedial actions. The relevant reports and justifications shall also be published. F6 ...
