About 4am this morning I thought about posting something, but
thought the power companies would mysteriously find some extra
power at the last minute again.

The rest of us were hoping, too...

No rolling blackouts are currently planned, but 15,000 Megawatts
is currently off-line (1/3 of normal capacity). If there are rolling
blackouts, most likely would occur between 4pm and 8pm. CAL-ISO
declared a "Stage 3" emgergency, but called for a reduction of 0MW
(that's a zero) of interruptiable load. So I'm guessing the purpose
of declaring the stage 3 was to activate some other programs, such as
shutting down the water pumps between northern and southern california
again. Something which apparently is only done during a State 3 emergency.

They've just announced the first set of rolling blackouts (assuming nothing
gets fixed in the immediate future), starting at 1600 PST (local time),
covering the Redwood city area. At least, in theory.

Diablo Canyon nuclear power plant is operating at 20% capacity due
to high surf conditions. (

Reportedly problems with kelp in the intakes. Never a fun situation...
