If anybody finds a good reference to official specifications, please let me 

Palo Alto has it's own power distribution system.  Years ago, somebody told 
me that they (or a friend) had called the Palo Alto power dept trying to get 
info on how accurate the line frequency was.  After he finally got through to 
the right person, the answer was "We are not tariffed for that."

Here is PG&E's blurb describing what they provide:

Page 7 says:
  PG&E will exercise reasonable diligence and care to regulate and maintain 
  frequency within reasonable limits but does not guarantee same.

These are my opinions, not necessarily my employer's.  I hate spam.
