If a BA performed a 5% voltage reduction but has not shed firm load, in what level of Emergency Event Actions (EEA) is this BA categorized?

When a balancing authority (BA) implements a 5% voltage reduction without shedding firm load, it is categorized as an Emergency Event Actions (EEA) Level 2 scenario. This classification indicates a significant response to manage system conditions while maintaining operational integrity without resorting to more drastic measures like shedding load, which would be escalated actions associated with higher EEA levels.

EEA Level 2 reflects a proactive approach where voltage reduction is utilized as a means to stabilize the grid and prevent further deterioration of system conditions. Since the BA has maintained firm load, it demonstrates a commitment to providing reliable service while managing the operational constraints facing the system. This action is primarily focused on avoiding load shedding or more severe measures while still addressing voltage stability concerns. In contrast, higher EEA levels would involve more critical actions, such as shedding load, which are not applicable in this scenario, reinforcing why Level 2 is the appropriate classification.
