PG&E told a federal judge that a sweeping plan to dramatically alter the landscape, cutting trees and inspecting the entire electrical system to ensure the company's lines do not spark deadly California wildfires this year would be exorbitant, ahead of a hearing Wednesday. For perspective, the $75-$150 billion cited by PG&E dwarfs the cost of President Trump's border wall proposal, which has been estimated to cost between $22 billion and $70 billion.

PG&E cites the following numbers:

• $75-$150 billion in costs to do the work

• 100 million or more trees to be removed

• 650,000 full-time employees to handle the workload

• A potential $30 billion is the liability PG&E said it faces after the 2017 and 2018 wildfires, as it considers bankruptcy.

If it did have to comply, PG&E says it would pass the cost to customers, with an exponential rate hike as follows:

• Five times increase in typical electrical bills, for one year, at the low end of estimates

U.S. District Judge William Alsup is overseeing the company's probationary measures following its conviction on charges related to the deadly 2010 San Bruno gas pipeline explosion.
