PS The largest and 3rd largest holders of US equity are those CA public sector union pension funds. They have far deeper pockets than PG&E by at least 10x.
Which set things up so the money PG&E makes is a linear function in the money PG&E wastes. -- the regulations set a fixed profit margin, so to make more money PG&E need simply waste more money and pass the cost onto the public which is exactly what they are doing.
