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? For many, a power outage is more than just an inconvenience—it can pose serious risks, particularly in extreme climates where heating or cooling is essential for safety.
Fortunately, GM Energy offers a solution that can alleviate these concerns. With the GM Energy PowerBank and a vehicle like the GMC Sierra EV Denali, homeowners can maintain power for their essential needs during a blackout, offering both convenience and peace of mind.
At a recent media event, GM showcased the GMC Sierra EV Denali electric pickup truck and the GM Energy Home System, highlighting their innovative energy solutions. The system includes various components that enable energy transfer between a compatible EV, such as the Sierra EV Denali, and a properly equipped home. This technology allows homeowners to use stored energy from their vehicles or stationary batteries during power outages or periods of high electricity demand.
The GM Energy PowerBank
A central part of this system is the GM Energy PowerBank, a stationary battery designed for residential use. Installed in a garage or other convenient location, the PowerBank charges automatically when power is available from the grid. During a blackout, it can provide energy to power essential home appliances and systems. Additionally, the PowerBank can help homeowners save on electricity costs by supplying stored energy during peak demand periods when utility rates are higher.
For those with solar panels, the PowerBank can store surplus solar energy. This stored energy can then power the home during cloudy days or at night, supplementing the charge of an electric vehicle. This integration with renewable energy sources makes the PowerBank a versatile tool for sustainable living.
The PowerBank comes in two capacities: 10.7 kWh and 17.7 kWh. For greater energy needs, two large PowerBanks can be combined, providing a total of 35.4 kWh of storage. With this setup, the average American home can be powered for up to 20 hours, ensuring that critical systems and appliances remain operational during extended outages.
The Power of Bidirectional Charging
The capabilities of the GM Energy Home System are further amplified when paired with a GM electric vehicle equipped for vehicle-to-home (V2H) bidirectional charging. The 2025 GMC Sierra EV Denali is a prime example of this technology. Known for its performance on the road, the Sierra EV Denali delivers up to 760 horsepower and 785 lb-ft of torque. With the optional Max Range battery, it boasts an impressive GM-estimated range of 460 miles on a full charge.
Beyond its road capabilities, the Sierra EV Denali shines as an energy resource during blackouts. Thanks to V2H bidirectional charging, the truck can transfer power from its battery to a home. A fully charged Sierra EV Denali with the Max Range battery can power a typical American home for up to 21 days, assuming reduced daily energy usage. This capability provides a reliable backup power source during inclement weather or utility outages, ensuring homeowners can weather extended disruptions without significant lifestyle changes.
Modular and Customizable Energy Solutions
The GM Energy Home System is designed with flexibility in mind. Its modular nature allows homeowners to tailor the system to their specific needs, whether that involves EV charging, backup home power, or solar energy storage. The system’s components are accessible and manageable through GM’s mobile apps, providing a seamless and integrated user experience. These apps allow customers to monitor energy transfer between connected GM Energy assets and manage their stored energy efficiently.
Accessible Information and Support
To help customers explore and understand these innovative solutions, GM provides multiple resources. The GM Energy website (gmenergy.gm.com) offers detailed information about the system and its components. Additionally, GM Energy Live allows users to chat with product specialists in real time and explore solutions through an immersive digital experience. This level of support ensures that potential buyers can make informed decisions and maximize the benefits of their GM Energy products.
Peace of Mind During Power Outages
Power outages no longer have to mean uncertainty and inconvenience. With the GM Energy PowerBank and a vehicle like the GMC Sierra EV Denali, homeowners can rest assured that they’ll have reliable backup power for their essential needs. Whether it’s keeping the lights on, preserving food, or maintaining a comfortable indoor temperature, these solutions provide the energy security that modern households demand. In a world where reliable energy is more important than ever, GM Energy offers a glimpse into a future where power outages are a challenge easily overcome.
