Seven-day advanced outage submittal

California ISO Tariff Section 9.3.3 gives the ISO the authority to reject outages submitted in less than 72 hours but does not address rejecting outages submitted less than 7 days and greater than 72 hours. The ISO will propose tariff revisions that clarify when a transmission outage request must be submitted and provide criteria for accepting or rejecting outages that are submitted less than 7 days in advance of the outage start date. Submitting outage requests in advance will allow the ISO to complete needed analysis and provide approvals in time to comply with Western Electricity Coordinating Council (WECC) reporting requirements.
