What is the default contingency reserve restoration period according to BAL-002?

The default contingency reserve restoration period as specified in BAL-002 is set to 90 minutes. This timeframe is crucial as it reflects the operational requirements for maintaining the reliability of the bulk power system. In the context of balancing supply and demand, the restoration of contingency reserves must be achieved within this specified period to ensure stability and minimize the risk of disruptions.

The 90-minute duration is intended to provide sufficient time for resources to respond and for the system operator to restore the system to its desired operating levels after a contingency event, such as a sudden loss of generation or a transmission line. This aligns with the broader goals of reliability coordination, focusing on not only maintaining balance immediately following a contingency but also ensuring that reserves are adequately replenished within the set timeframe. This understanding is vital for reliability coordinators and operators who are tasked with implementing these regulations in real-time operations.
