Tesla’s Powerwall can ironically create problems if you’re all-in on the company’s ecosystem. What happens if there’s a power outage and the battery pack has to juggle the needs of both your home and your EV? You might rest a little easier from now on. Teslerati reports that Tesla has released a Powerwall update that will coordinate with the company’s cars to prioritize charging during power outages. Charging will slow down if there’s a high load in your household during the outage, and will even stop entirely if the Powerwall dips below an “energy threshold.”

The feature is currently available to North American owners who drive a Model 3 or Model Y. You’ll have to be patient if you live elsewhere or drive one of Tesla’s higher-end EVs. If you do qualify, though, this could ensure that you aren’t left in the dark simply because your car was a little too thirsty during a bad storm.

If you feel like you need the company’s help, input the code “POWERRELIEF19” into the Lyft app. You can access the part of the app where you add promo codes by tapping the three lines icon located at the top left of the interface, and then tapping on the “Promos” section. Lyft says the code is valid for two rides up to $15 each. The company is also working with United Way and 211 to provide free evacuations to individuals with specific needs.

The outreach is part of Lyft’s Wheels For All initiative, which has seen the company offer similar help during natural disasters like Hurricane Dorian.

Why cut the power?

It’s become evident that overhead power lines are to blame for some of California’s worst wildfires. Sparks from those power lines have ignited some of the largest and most deadly fires in recent history, including the Camp Fire in Paradise, California.

As the state enters peak wildfire season, officials are keeping a close eye on local weather conditions. With low humidity and high winds forecasted, the National Weather Service has issued red-flag fire danger warnings in parts of the state. Taking a proactive approach, PG&E has decided to cut power in order to minimize fire risks.

When, where and for how long?

As of this morning, more than 500,000 PG&E customers are without power. The outages will roll out throughout the day, and they’re expected to impact 34 counties. A full list can be found on the PG&E website.

The company says the outages could last several days, possibly extending until next Tuesday. The utility plans to begin restoring power beginning Thursday, but technicians will have to carefully inspect the lines and repair damage before power is restored. That process can’t begin until the winds have died down, and it could take several days.

What does this mean for Californians?

According to The New York Times, the primary mass transit systems in the San Francisco Bay Area — BART and Caltrain — plan to remain open. Some schools in San Jose and Oakland have closed, and the University of California, Berkeley, canceled classes today. Police officers have been called in to direct traffic, and shoppers are wiping shelves clean of batteries, water and other supplies.

Tesla issued warnings to its EV customers to charge their batteries fully ahead of the outages, and its PowerWall home battery packs are running Storm Watch to store excess power before the lines go down.

PG&E has set up 30 facilities with the essentials: bottled water and outlets to charge electronic devices.

What does PG&E have to say?

“The safety of our customers and the communities we serve is our most important responsibility, which is why PG&E has decided to turn power off to customers during this widespread, severe wind event. We understand the effects this event will have on our customers and appreciate the public’s patience as we do what is necessary to keep our communities safe and reduce the risk of wildfire,” said Michael Lewis, PG&E’s senior vice president of Electric Operations.

Is this the new norm?

PG&E has come under intense scrutiny for its role in past wildfires. The company filed bankruptcy in January due to tens of billions of dollars in wildfire liabilities. Its $30 billion recovery plan includes proactively removing trees, brush and debris around electrical wires and increased use of “grid de-energization” — that is, outages like this one.

So, in short, yes, planned “Public Safety Power Shutoffs” will likely become a more common occurrence for Californians. For that reason, some are calling for electric utilities to bury power lines, but that would be a massive, costly and lengthy process.

If you own a GM vehicle that is a 2006 model or newer, it’s likely it has OnStar hardware installed. Car owners who no longer pay for OnStar can still access the service for free during the hurricane. Advisors will be available to assist 24/7.

GM isn’t the only automaker providing natural disaster support. Tesla is helping those impacted by Hurricane Dorian by offering free Supercharging, enabling Powerwall’s “storm watch” feature and enabling more range on some vehicles. Electrek noted that owners of a Powerwall — Tesla’s lithium ion battery — who were in Dorian’s path noticed that storm watch mode had been activated. The special emergency mode automatically charges the Powerwall at full capacity so it can provide backup power.

The Category 3 hurricane is expected to get close to Florida’s east coast by Tuesday evening and last through Wednesday. And local government and emergency services appear to be taking it seriously. “Hurricane Dorian is the strongest storm to ever threaten the state of Florida on the east coast,” said Jared Moskowitz, director of Florida’s Division of Emergency Management. “No matter what path this storm takes, our state will be impacted.”
