must run for security of supply, when available: MP1, MP2, MP3, TYC, TB3,
B10, and either K1 or K2.

manage operating hours on these units (system conditions depending).
- K1/K2 to be dispatched
at min gen where possible to manage operating hours on these units (system
conditions depending).
- (Addition of K1 and K2
to Run Hour Preservation group): To ensure that the equivalent operating
hours on K1 and K2 are effectively managed to minimize risks for margins
across winter 2021/22.
