  • 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.
    • Outcome
      This amendment requires participating transmission owners to submit a request for a planned transmission maintenance outage or a change to an approved maintenance outage at least seven days in advance of the start date for the outage. The timeline for submitting the required advance notice is calculated by excluding the day the request is submitted and the day the outage is scheduled to commence. — Effective: Aug. 6, 2012; FERC approval: July 25, 2012 (ER12-1972); Board of Governors approval: Feb. 16, 2012
