In the bay area, Santa Clara has city owned power, and residents pay something like a third of what the rest of the bay area does per kilowatt hour.

Part of the inspiration for why SF is trying to kick out PGE and have municipal power.

SVP delivers over 90% of their energy to commercial customers, making it a bit of a special case. However it does prove the hypothesis that large-scale consumers tend to lower, not raise, the local retail price for energy.

As for SF, there is no real sense in which they are trying to kick out PG&E. While there is and always has been a vocal group of SF residents who want a free pony, when it comes down to paying the bills SF has voted in 12 separate elections to not establish a municipal utility. They have a demonstrated history of failure to invest in their own utilities stretching back 100 years.
