Wildfires pose potential crisis -- and opportunity -- for PG&E

Wildfires create worst crisis for PG&E since San Bruno gas disaster | The Sacramento Bee: California’s wildfires have left Pacific Gas and Electric Co. confronting its most serious financial crisis since the 2010 San Bruno gas explosion, a disaster that threatened the company with bankruptcy and ultimately cost the utility $1.6 billion in fines and other costs. Two state agencies, Cal Fire and the California Public Utilities Commission, have launched investigations into whether Northern California’s largest utility could be at least partly responsible for the fires that ignited Oct. 8, killing at least 41 people and destroying roughly 5,700 homes and businesses. So far, neither Cal Fire nor the CPUC has cited evidence that PG&E contributed to any the ignitions. But the stock price of parent company PG&E Corp. has plunged over the last week amid investor jitters that the utility could be held responsible. PG&E shares closed Monday at $53.43, a drop of $4.34. Since Friday the company’s stock market value has fallen by more than $5 billion.

The threat of wildfires sparked by electric power transmission lines in PG&E's Northern California service territory will continue into the future after the recent deadly wildfires that ravaged California’s wine country, killing more than 40 people and destroying several thousand homes and businesses. Some predict the hazard will worsen due to climate change and continued residential development near fire prone wildland areas.

Out of crisis, goes the adage, opportunity often follows. For PG&E, that opportunity is to vastly reduce the chance of its power lines starting destructive wildfires and subjecting the company and its shareholders to significant legal liability. How so? By placing its last mile distribution lines serving customer premises in buried underground conduit instead of suspended overhead on wooden poles close to combustible flora and other materials. 

There’s an additional bonus on top of the reduced maintenance and storm outage costs associated with above ground transmission poles and infrastructure. PG&E recently filed an application with California utility regulators to serve as a wholesale telecommunications provider using its fiber optic infrastructure. Conduit for underground electrical power cables could also house fiber for telecommunications and bring it close to residential, business and institutional PG&E customers. PG&E could lease that fiber to internet service providers, providing an additional revenue stream to help offset the cost of undergrounding its premise electrical service lines.

And that's not all. In placing electric power lines in underground conduit, electric utilities can apply shielding to protect the grid from damaging electromagnetic flux from X-class solar flares or EMP weapons detonating at high altitude.

Awesome write up. It would be great if PG&E could adopt Rule 20D in their undergrounding program like SDG&E had done in 2012. Rule 20 is facilitated by CPUC and Rule 20D focuses primarily working with fire agencies (CALFIRE) to determine fire caution zones that require undergrounding of overhead utilities to prevent wildfires. PG&E does not have the rule adopted, but after this fire, major reform could and should occur in utility infrastructure.
Perhaps CASF funding criteria could be adjusted as a unique case for those areas affected by fire and incentivize telecoms providers to utilize cooperation with other organizations to expand footprint, protect infrastructure, and lower costs.

Lots of potential here.

This solves two problems at once since those areas of Northern CA with the highest wildfire risk also tend to have the most deficient telecommunications infrastructure.
