How GM Energy and the GMC Sierra EV Denali can help in a blackout
2024-12-12
With a GM Energy PowerBank system and a GMC Sierra EV Denali, you can stay safe and comfortable through a power outage.
Nobody enjoys a power outage. When the lights go out, the worries begin. How long before the food in the fridge goes bad, or the phone battery dies? And a power outage is often more than just an inconvenience. A lack of heating or air conditioning for an extended period can be dangerous in extreme climates.
But with a GM Energy PowerBank, you’ll have battery backup to provide power to your home. And with a vehicle like the GMC Sierra EV Denali in your driveway, you can provide power to your home’s essentials for days if needed.
At a media event showcasing the GMC Sierra EV Denali electric pickup truck, GM demonstrated the full capability of the GM Energy Home System, which includes components to enable energy transfer between a customer’s compatible EV, such as the Sierra EV Denali, and a properly equipped home.
The system includes the all-new , a stationary battery that can be installed in your garage. When power is available from the grid, the PowerBank automatically charges up. You can use this stored energy whenever it’s needed.
During a power outage, the PowerBank can energize your home’s essentials. You can also use the stored energy during periods of peak demand, helping to offset the cost of higher electricity rates. In homes equipped with solar panels, the PowerBank can store solar energy to power your home and help to supplement the charge from your electric vehicle.
The GM Energy PowerBank is available in two capacities, 10.7 kWh or 17.7 kWh. Two large fully charged PowerBanks, providing 35.4 kWh, can power the average American home for up to 20 hours1.
And PowerBank gets even more powerful when it’s combined with a GM electric vehicle equipped for vehicle-to-home (V2H) bidirectional charging.
Take the 2025 GMC Sierra EV Denali. On the road, this is a powerful all-electric pickup truck, packing up to 760 horsepower and 785 lb-ft of torque2. When equipped with the optional Max Range battery, the Sierra EV Denali provides 460 miles of GM-estimated range3.
V2H bidirectional charging is standard on the Sierra EV Denali, just one of many GM electric vehicles to offer this capability. A fully-charged Sierra EV Denali with the Max Range battery can provide power to a typical American home for up to 21 days with reduced daily energy usage4, providing peace of mind during inclement weather or utility outages.
The GM Energy Home System is modular, enabling custom-tailored solutions for EV charging, backup home power, and solar energy storage. The products are accessible through current GM mobile brand apps, allowing customers to seamlessly manage the transfer of stored energy between applicable and connected GM Energy assets, for a fully integrated and convenient experience.

1The GM Energy Storage Bundle shown requires a fully charged and properly equipped PowerBank, and proper grid interconnection. The U.S. Energy Information Administration (EIA) estimates average daily home energy appliance usage to be 30 kWh. Weather conditions, life of the battery, PowerBank usage and other external factors may impact the duration of time. Power supply may be interrupted: not recommended for medical devices.

3On a full charge. GM-estimated when equipped with the available Max Range battery. On a full charge based on development testing and/or analytical projection consistent with SAE J1634 revision 2017 – MCT. Actual range may vary based on several factors, including ambient temperature, terrain, battery age and condition, loading, and how you use and maintain your vehicle.
4Based on 2024 Sierra EV Denali Edition 1. See GMC.com/electric/sierra-ev/denali-edition-1 for details. The GM Energy PowerShift Charger and GM Energy V2H Enablement Kit shown requires a fully charged and properly equipped Sierra EV Denali having bidirectional charging capabilities, a properly equipped home, and proper grid interconnection. Power supply from the vehicle may be interrupted but will provide partial power to your home for up to 21 days collectively. Length of time may vary depending on energy usage. 21-day power supply represents energy usage of 5.3 kWh per day, which requires limiting the use of devices within the home. The U.S. Energy Information Administration (EIA) estimates average daily home energy usage to be 30 kWh. Weather conditions, life of the battery, vehicle variation and usage and other external factors may impact the duration of time. It is not recommended that the following devices be powered with the GM Energy PowerShift Charger and V2H Enablement Kit: Medical Devices
