Absolutely they can be buried. They must be insulated, but that's not particularly expensive. There are thermal limits, as you mentioned, but that simply requires appropriate engineering.

It costs $1 million per mile (roughly) to bury transmission lines. PG&E has about 18,000 miles of transmission lines. That's about $18 billion to bury the lines. Sounds like a lot, but...

...the estimate price of these multi-day blackouts is on the order of $1 billion per blackout. Given multiple blackouts per year, and we're talking just a few years to pay back the price of burying the transmission lines. https://www.sfchronicle.com/business/article/A-cool-billion-...

But that's not the cost to PG&E. PG&E (or the state) would have to find a way to get some of that somewhat hidden opportunity cost.

The state already does that through regular, economy-wide taxes. (Maybe this is why it's a bad idea to grant a monopoly to a for-profit company like PG&E that doesn't take into account the externalities of power outages... Then again, Texas' very deregulated but non-monopoly ERCOT seems to do pretty well. So either state-owned OR deregulated may be optimums compared to PG&E...)

$1m/mile is off by like a factor if 10. PG&E thinks it costs $3-5m/mile to bury _distribution_ lines: http://www.pgecurrents.com/2017/10/31/facts-about-undergroun...

Good argument for burying PG&E, then, and starting over.
