State Sen. Scott Wiener has introduced a bill that could make it easier for San Francisco to break away from PG&E, but questions remain about cost, timing, and potential ripple effects. The bill would lower the bar for cities to switch to a public provider and enforce tighter CPUC timelines. It aims to reduce excessive court filings and shorten the process for valuing PG&Es's assets. However, if San Francisco exits the system, wildfire mitigation costs would be spread across a smaller base, increasing rates for remaining customers. Despite this, critics argue that public power comes with trade-offs, which could lead to increased costs and better management.
