No municipals, even the biggest like LA's, tackles anything near the scale of even our smallest IOU. Most critics of the IOUs ignore the sheer scale and geographic challenges of running a service area larger than some states across many different types of terrain. Running retail distribution and metering isn't that hard when other people run the grid for you. PG&E, SCE, and SDG&E have lots of issues to be sure, but to compare them to SMUD or Modesto is far from apples to apples.
