On Nov. 2, 2023, the California ISO issued an Exceptional Dispatch Capacity Procurement Mechanism (CPM) designation to address a non-system reliability need to SYCAMR_2_UNIT 3. The quantity of the designation was 70 megawatts (MW). The Exceptional Dispatch was issued to address a potential thermal overload in the Southern California Edison Local Area for the next contingency event. The ISO observed post-contingency thermal overloads on a 230 kV transformer for the loss of another 230 kV transformer in the Southern California Edison area. In order to relieve the overload, the ISO exceptionally dispatched the specified quantity from this unit to maintain reliability.
The ISO has designated the capacity identified below effective Nov. 2, 2023 for a non-system reliability need. The CPM term is for 60 days under the tariff, subject to adjustment and the payment provisions set forth in the CPM tariff provisions.
