When does the contingency reserve restoration period begin for a Balancing Authority or Reserve Sharing Group?

The contingency reserve restoration period for a Balancing Authority or Reserve Sharing Group indeed begins at the end of the Disturbance Recovery Period. This is a crucial phase where the system has already addressed the immediate impacts of a disturbance, and normal operations are being regained. The Disturbance Recovery Period is defined as the time frame in which the system recovers from a disturbance, ensuring that the reserves and operational stability are restored to their pre-disturbance levels.

Once this recovery is complete, the focus shifts to the contingency reserve restoration period. During this time, the Balancing Authority or Reserve Sharing Group is responsible for replenishing any reserves that may have been utilized to maintain system reliability. This ensures that the system is prepared for future contingencies and maintains its reliability standards.

Understanding when the contingency reserve restoration period begins is essential for effective operational planning and response in the electric power sector, as it helps coordinate efforts to ensure long-term stability of the grid.
