Running solely off solar power, from Southern CA:

Why wasn't there any 24 hour or 48 hour forecasts issued? This was clearly foreseeable by yesterday at the latest. Does it have anything to do with FERC's formula for setting price caps, this under- prediction and under-stating the seriousness of California's grid conditions?

From the above notice:

"A 'Stage 3 Emergency Notice' and 'Notice of Load Interruptions' will be issued by the CAISO when the load interruptions have actually begun or are imminent."

Don't know what happened to 1.5% trigger.
