Rate Schedule PACI-T5 and PACI-T5 REV
An equitable rate, based on the WAPA-SN COTP transmission formula rate, to charge for surplus PACI transmission used for non-Statutory Service. This is a new rate schedule and applies to any entity purchasing surplus PACI transmission posted on OASIS.
Rate Schedule PACI DLAP-T6
An equitable rate, based on the WAPA-SN’s cost for wheeling power through the California Independent System Operator balancing authority area, to charge for surplus PACI transmission used for non-Statutory Service. This is a new rate schedule and applies to any entity purchasing surplus PACI transmission posted on OASIS.
WAPA-SN is conducting a formal rate process for PACI PTP transmission service to be completed within a year. In the meantime, rates for short-term sales are needed to charge cost-based and equitable rates, and allow time to conduct a formal public process.
