(Bloomberg) -- Some of the most widely discussed ways to prevent the massive fires and blackouts that plague California may also be the most expensive, according to BloombergNEF.
For instance, burying all 81,000 miles (130,000 kilometers) of PG&E Corp.’s electrical distribution lines so they won’t spark blazes during windstorms could cost more than $240 billion, a BNEF study found. That’s based on a PG&E estimate that moving existing lines underground costs $3 million per mile.
A state takeover of the troubled utility would also likely have a hefty price. The book value of PG&E’s electricity assets -- the amount they’d cost if new -- is $62 billion, according to the BNEF study. The state would almost certainly negotiate a lower price to account for depreciation, but it would also have to assume PG&E’s liabilities. Plus, a takeover wouldn’t necessarily prevent fires.
“If regulators are willing to allocate enough time and money, most proposals will reduce wildfire risk. None will eradicate risk,” BNEF analyst Helen Kou wrote in the report.
The findings underscore the immense challenges California faces as it pushes to end deadly wildfires and the sweeping, deliberate blackouts intended to prevent them. PG&E, the state’s largest utility, filed for Chapter 11 last January facing $30 billion in liabilities from the blazes, which have erupted with increasing frequency as climate change fuels hot, dry weather.
