I was actually going to disagree on first glance but I absolutely agree with this.

Transmission has no business edge, you will gain the best economies of scale by having the city (or larger regional) manage it.

Free-market works on the generation side because as prices change, producers can decide to build out more capacity or innovate to gain an edge. I don’t think a single monopoly construct, like the PG&Es of the world, have incentive to innovate and properly serve the market.
