The other angle that people may not realize is that SF has voted in nine separate elections to not establish a municipal utility. The people of SF demonstrably do not want to take over PG&E, given numerous opportunities.
SMUD has cheap power because 100 years ago the people of Sacramento invested a lot of money to establish that utility. What the vocal minority of SF public power people want is magical: cheaper rates without all that bothersome investment.

But PG&E has charged significantly more for power the last few years. Most people easily hit 50c/kwh on their bills.
Compare to Santa Clara, which has their own well run utility, and charges less than half PG&E rates.
