> California ISO power grid peak demand hit 52,061 MW, a new all-time record. Still holding in EEA3 - no load shed. Conservation is making a difference. ow.ly/brMu50KBKHT
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]
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.
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.
