Looked like no blackouts were needed yet.[0] > California ISO power grid peak demand hit 52,061 MW, a new all-time record. Still holding in EEA3 - no load shed.

Anecdata: I personally know 2 people in South Bay that lost power 2 hours ago.

  Ours has been out for about 5 hours now. Also South Bay. :-(

We had rolling outages in the Bay Area in Alameda at least. They did two circuits at a time instead of one too. https://twitter.com/alamedamunipwr/status/1567321973033943041?s=21&t=VQDudBnoVVVk3mV4Wjyfew https://twitter.com/alamedamunipwr/status/156732197303394304...

  Unless the official CalISO twitter account is lying, this could be a local issue for specific substations etc. With the weather there could be transformers overheating and failing, for example. In a large state, power goes out _somewhere_ quite often. The bag of tricks CalISO has to lower demand at peak is fascinating - for example, there are large consumers with significant generation resources (like emergency generators) that sign in to turn the generators on and get off the grid for a couple of hours. This produces drops in demand without blackouts per-se. Distributed power generation is generally more resilient.

    Seems to have been directed by CAISO for both Palo Alto and Alameda: https://twitter.com/nukebarbarian/status/1567358316174622720 https://twitter.com/nukebarbarian/status/1567358316174622720

      Thanks. Interesting, indeed. Maybe they're using different terminology; otherwise it's not clear how both Caiso and these local utilities can be truthful at the same time.

There may be no rolling blackouts needed, but at least part of that is because of the involuntary ones. There's a lot of red (>5000 people) and orange (1000-5000 people) in the current map [1] [1] https://pgealerts.alerts.pge.com/outagecenter/ https://pgealerts.alerts.pge.com/outagecenter/
