Every time we have a serious ice storm or tornado that takes down power lines our rates go up. They are to cheap to put them underground where they belong.

it?

Each building gets a trench? I guess and that will link to a bigger trench then bigger until the whole grid is underground?

Will those trenches cause any inconvenience to anyone, traffic patterns?

they just would not see it "immediately" which is what they want. Utilities should be a public thing not a private one.

the ones that go from substations out to facilities and individual customers. But it's not so easy (or cost effective) for the high voltage (385kV and up) Transmission lines that one sees going through the countryside on those big towers. There are problems with physics in trying to put them in the ground in a cost effective (affordable) manner. (Corona effects and induced currents in ground.)

High Voltage Direct Current (HVDC) transmission lines can handle underground installation a bit better, but they have their own problems and are not so common.

Here's a pretty good layman's level article on the issue with the distribution lines:

There are lots of others out there if you are really interested.

My last bill was $200. I can sure afford to pay PG&E $1,000/month.

They still need their bonuses

regulated by the California Public Utilities Commission. It serves the northern part of California. PG&E is one of four regulated, investor-owned utilities (IOU)s in California; the other three are PacifiCorp's Pacific Power, Southern California Edison and Sempra Energy's San Diego Gas & Electric.

I guess I would call it a monopoly, but it's rates are controlled by the PUC.
