The outage blocks are announced as soon as they are placed by the
utility, so thieves know that very quickly. That is of limited value
in that the information of who is in which block is NOT public
information. And the "blocks" are not contiguous areas but fairly
small areas scattered all over the utility's service area (and over
other utility's areas which get their power fed through the utility.

the idea behind this is that the crooks will only know that block 'x'
is off, but not what physical locations are in block 'x'. Reality is
that the local news panning over San Francisco after sunset from
Mt. Sutro makes the area without power quite obvious.

A mailing list per block seems a good idea. That way customers could
subscribe to the list(s) in which they have equipment. The problem is
that PG&E has been shutting down PORTIONS of a block. The next
shutdown will be "within block 14". So a notification that block 14 is
going down would only mean that your power MIGHT be going out. :-(
