The intentional blackouts that have left millions of Californians without electricity this week have been branded “public safety power shut-offs” because they were intended to stop downed utility lines from sparking the kind of devastating wildfires that level communities and kill people. On the face of it, that sounds reasonable: After all, more than 2,000 fires—including the state’s deadliest and most destructive—have been sparked by electrical lines or equipment since 2014.
But the troubling fact is that despite the shut-offs, fires around California may still be igniting as a result of downed lines. At least four fires this month may have been started by electrical equipment that was not shut off despite the dangerous weather conditions.
So what’s going on here? At this point, Californians can legitimately wonder whether the blackouts are being employed in a sane or sensible manner. Are we experiencing fewer fires than we would without them—or are they ineffective because they’re badly thought out or poorly implemented?
We always knew that the preventive power shutdowns would come with certain costs. And when the final toll of October’s outages are tallied, the human, financial and environmental costs are likely to be staggering—thousands of refrigerators filled with spoiled food and medicine, lost paychecks from shuttered businesses, people hurt in accidents caused by the lack of traffic lights and untold amounts of greenhouse gases spewed into the atmosphere by diesel and gasoline power generators.
On top of that, there were serious problems with the implementation from the start. The websites of PG&E and Edison were unable to handle the volume of people trying to find out whether they’d be affected. State and local emergency providers weren’t given adequate notice of the shutdowns. There was little explanation why power was cut to some communities and not others.
If, in return for all that chaos and cost, the utilities were successfully preventing power lines from starting deadly fires, then it would be worth it. After all, San Diego Gas & Electric has used targeted blackouts during high-fire risk conditions successfully for a decade. But are we in fact safer?
If Californians are going to have to endure a decade of planned power outages until the electrical grid is reformed and hardened enough to cope with the new realities of climate change, then we deserve as much reassurance as is reasonably possible that the dark days are making us all safer.
