The CAISO understands that the CPUC may provide, on a quarterly basis, updated obligations/credits for their jurisdictional LSEs due to load migration or other factors. Where the CPUC provides such updates, the CAISO will incorporate the updated obligations/credits into the LSEs’ monthly RA requirements as soon as feasible. The CAISO will only use the updated requirements for the month-ahead RA process; updated requirements will not be used to change existing annual CPM cost allocations. If the updated CPUC allocation relates to local RA obligations and the updated allocation does not fully allocate the total sum of each CPUC Load Serving Entity’s proportionate share calculated under Section 40.3.2(a), then the ISO will allocate to CPUC load serving entities the difference using the default allocation provisions under section 40.3.2(c) of the tariff.
