They are not on a different grid at all. Most of California, and definitely the entire Bay Area is part of the same grid managed by CAISO:

Palo Alto has its own municipal utility. There is a huge difference. A municipal utility is only responsible for retail electric sales and distribution infrastructure in a specific area. That includes local substations and power lines, which are the likely source of your electricity reliability problems.
Palo Alto doesn't manage supply and demand in real time, maintaining 60Hz AC, or run the wholesale electricity markets. CAISO does those, along with transmission and regional interconnects, all of which are functions of the electric grid. The meanings of words matter when discussing these things.

Thank you for the pleasant feedback.
