Scpe/Applicability Crdinatin during Bulk Electric System (BES) Emergencies r during cnditins r events that culd result in Adverse Impact n the BES. As defined in the NERC Glssary, a BES Emergency is any abnrmal system cnditin that requires autmatic r immediate manual actin t prevent r limit the failure f transmissin facilities r generatin supply that culd adversely affect the reliability f the BES. In additin, the NERC Glssary defines Adverse Impact as the impact f an event that results in frequency-related instability; unplanned tripping f lad r generatin; r uncntrlled separatin r cascading utages, that affects a widespread area f the Intercnnectin. 3. Detail 3.1. Capacity and Energy Emergencies Each Balancing Authrity (BA) shall develp, maintain, and implement an RC-reviewed Operating Plan t mitigate Capacity and Energy Emergencies within its Balancing Authrity Area 1. During a BA Capacity r Energy Emergency, the RC peratr will declare an Energy Emergency Alert (EEA) fr the affected entity. This may be at the request f the BA, r when deemed necessary in the judgment f the RC peratr. There are three levels f EEAs and an additinal terminatin level 2. It is nt necessary t prgress thrugh the levels sequentially, and the RC peratr shuld use gd judgment in declaring the level best defined by the criteria. Public appeals fr cnservatin r demand respnse prgrams under cntractual agreements during nrmal peratins d nt qualify as EEA triggering events. Fllwing the activatin f Cntingency Reserves, a BA r Reserve Sharing Grup (RSG) must recver Cntingency Reserves within 60 minutes fllwing an event requiring activatin. If there is an additinal event that takes place during this recvery perid, the 60-minute recvery perid 1 EOP R2 2 Attachment 1-EOP B. 2
