Showing the 12 largest of 44 CAISO transmission records at or above 500 MW.
The last 3 row(s) are published path limits, not equipment outages: the 3 largest of 24 in today's report.
Neither figure is the size of what is out of service. "MW OTC in effect" is the transfer capability CAISO publishes for the interface with the outage applied; "MW path limit" is a limit the owner published on the path. Each is the highest value that record carries over tomorrow's intervals, and the rows are ranked by it, so the largest number is the least constrained interface, not the biggest outage.

Baseline: hourly DA-RT for NP15, SP15 against two windows -- the 30 days before 2026-11-14, and the same date in earlier years give or take 45 days, which follows the season rather than the calendar. Each z is robust (median and MAD), and this letter only says outlier at |z| of 3 or more; the percentile is where the hour sat inside its own 30 days. These are spread numbers, not price levels -- the table above has the day-ahead and real-time legs hour by hour. Malin is not in the price history. Seasonal comps reach back before EDAM went live on 2026-05-01.
