How much advance notice should emergency assistance for a capacity deficiency be scheduled by the BA?

The correct response emphasizes the importance of proactive planning in the context of capacity deficiencies within the bulk power system. When a Balancing Authority (BA) identifies a potential capacity deficiency, providing assistance with as much advance notice as possible helps ensure that all involved entities can adequately prepare and respond effectively. Early notification facilitates better coordination among different authorities, which is crucial for maintaining reliability in the electric grid.

This approach aligns with best practices in operational reliability, ensuring that all parties have sufficient time to mobilize resources, arrange for additional generation or load reductions, and take other necessary actions to mitigate the deficiency. By prioritizing advance notice, the BA not only aids in immediate responsiveness but also promotes long-term reliability and stability of the grid.

In contrast, options suggesting minimal notification or waiting until a deficiency arises undermine the reliability strategy necessary for effective grid management. Immediate responses, without preparation, can lead to inefficiencies and greater risk of service disruptions.
