California Utilities Are Turning Off Your Power

Protect your home from utility-mandated blackouts with home solar + battery storage.2

Update October 29, 2019: PG&E Begins Shutting Power Off for Next Offshore Wind Event Impacting Approximately 597,000 Customers.

This is the third Public Safety Power Shutoff in less than a month. - PG&E

Update October 8, 2019: PG&E Will Proactively Turn Off Power for Safety to Nearly 800,000 Customers Across Northern and Central California.

“Given the prolonged period during which the wind event will unfold, and the large number of power line miles that will need to be inspected before restoration, customers are being asked to prepare for an extended outage.” - PG&E

Update October 11, 2019: SCE Turns of Power For Over 21,000 Customers

"Power will be restored once conditions improve and SCE crews have completed patrolling each circuit to ensure it can safely be re-energized." - SCE


Wildfires are more destructive and deadlier than in the past, and the threat of wildfires is more prevalent throughout the state and calendar year. In an effort to prevent wildfires, Pacific Gas and Electric Company (PG&E), Southern California Edison, and San Diego Gas & Electric (SDG&E), may shut off your electricity during extreme weather and wildfire conditions. Power will remain out for as long as extreme and dangerous weather conditions pose a potential fire risk.2

California has endured the most power outages of any state. Between 2008 and 2017, California residents endured 4,297 power outages, or roughly 477 outages per year. This is more than double the amount of power outages endured by Texas residents, the number two state for power outages.3

  • Pacific Gas and Electric

    Public Safety Power Shutoffs began in 2018 after PG&E faced certain liability for 12 wildfires.4 In 2018, PG&E proactively turned off power to 60,000 customers.5 Between June - October 2019, PG&E customers experienced at least five PSPS outages affecting approximately 842,200 customers.6

  • San Diego Gas & Electric

    In November 2018, SDG&E shut off power to nearly 10,000 customers due to high winds, and nearly 20,000 more customers lost power. The power outages lasted up to five days.7

  • Southern California Edison

    In October 2019, SCE shut of power to over 20,000 customers.8 The red flag warning was extended from two to three days9 leaving some homes without power for longer than expected.

Be Prepared for Blackouts. Maximize your solar system with a battery

✓ Power Your Essentials in a Blackout - During a grid outage, your solar system can only produce and store energy during the day if you have a battery.

✓ Maximize Your Economic Benefit - With a time of use (TOU) rate plan, your battery automatically manages your energy flow to help protect you from peak rates and maximize your net metering credits.10

✓ Take Advantage of Incentives - You may be eligible for federal and state incentives that may cover up to 56% of the retail battery cost.11

✓ Hassle-Free Operation - System components are covered, reducing or eliminating out-of-pocket expenses during the term of your agreement. We’ll coordinate any repairs and maintenance.12

Why Pay Incredibly High Utility Rates For So Many Blackouts?

California residents experienced a 19% increase in utility rates from 2012-2017. On average, the cost of electricity in California is 18.24 ¢/kWh.1 Why pay so much money to your utility when you may not get reliable electricity service? There are alternatives.

Increase Your Energy Independence with Home Solar + Battery Storage

Control your energy costs and be less susceptible to rising utility costs and peak utility rates with a home solar + battery storage system.11


Protect Yourself from TOU Peak Rates with a Battery.

When electric grid pricing is at its peak, your home can be powered with the energy stored in the battery, sending excess energy to the grid so you maximize your solar benefit. This helps protect you from high utility rates to maximize the economic return from your system.10

2. The amount of power available from the battery during a power outage is limited, depending on the loads connected, customer usage and battery configuration (i.e. batteries in certain areas may be set up to provide you with the best economic benefit, which may affect the amount of back-up power available). Solar systems and/or batteries may require repairs after weather events and such repairs may be delayed due to forces outside of our control. No assurances can be given that the solar system or the battery will always work. You should never rely upon either of these to power life support or other medical devices.

10. Customers with time of use (TOU) utility plans may have their battery configured to provide the best economic benefit based on the utility information provided and in accordance with local state laws. The amount of back-up power under this configuration may be affected.
11. You may be eligible for a federal Investment Tax Credit (ITC) with the purchase of a solar battery. To receive the full federal tax credit, you must have federal income tax liability at least equal to the value of the tax credit. Additional tax credits may also be available for homeowners in certain states and territories. Customers in the State of California may participate in the self-generation incentive program (SGIP Program). Sunnova makes no guarantees regarding customer eligibility for tax benefits. Sunnova does not provide tax advice. Contact your personal tax advisor for eligibility.
12. Individual savings will vary based on your utility rate, your energy consumption habits, the solar system equipment installed on your property, your tax incentives eligibility, weather and other factors. In some states Sunnova’s products are not designed to offer savings. Customers located in states or territories other than CA, CT, MA, RI, NY and NJ are likely to perceive savings substantially lower than 20%, if any. Individual savings estimates are based on your solar energy production, your solar kWh rate, potential tax incentives, your utility kWh rate at the time of purchase, and projected increases in the utility rate (based on historical data and national averages). Estimates do not take into consideration other changes in utility rates. Such changes could affect your overall estimated savings. Sunnova does not guarantee savings.
