If your garage door opener was installed prior to July of 2019, it probably does not have a backup battery. That means during a PG&E shutoff or wildfire evacuation, you cannot open your door electronically. You'd have to pull the manual release in the dark with the kids in the car. California law SB-969 now requires backup batteries on all new openers.
It's worth retrofitting before the fire season. An easy way to test if you have a backup battery is simply go up, disconnect your motor, and click the remote. See if it runs. If you're unsure whether or not your garage door opener have a backup battery, simply disconnect it from the power and run it. If it runs, you're good to go.
If it doesn't, it's worth investing in a backup battery operated garage door opener.
