I haven't seen Sean post about this yet, so figured I would.
California's been getting hit with a nasty storm since yesterday that's
taken out some more major power plants; the CAISO declared a Stage 3
(rolling blackouts all around) power emergency just before 9 AM PST today.
See http://www.caiso.com/SystemStatus.html for pretty graphs.
Have you test-run your backup generators and transfer switches lately? }:>

More particularly, for those who negotiated lower power rates in
exchange for a promise to remove themselves from the grid in the event
of such, does ANYONE at your NOC know how to do this without blowing
your UPS?

We are now running on emergency power. Calls to PG&E about outages are get a
recording that rolling blackouts are in progress.

PG&E started with "block 3" (look on your power bill for what block number
you are) -- assuming 1 hour per blackout, and they go through the block
numbers in sequence, you have an idea of when you'll get hit. Anyone have
an idea of how many PG&E blocks there are?
