Even if SF lost the hydro plant outright (which seems unlikely) there's still plenty of margin for SF residents to come out on top. SVP in Santa Clara doesn't own much generation, yet its rates are 60% lower.[0]

Then there's the state-wide need to increase transmission capacity because of the switch to renewables, the future politics of which are kinda unpredictable. It's hard to imagine SF getting singled out and left out in the cold, considering the state already has many large municipal utilities getting better deals for their residents.
