General Motors is expanding the role of electric vehicles beyond transportation, unveiling how Cadillac’s lineup of EVs can now serve as backup power sources for homes during outages. Through the GM Energy Home System, Cadillac models equipped with bidirectional charging can store and supply electricity to homes, offering a new level of resilience amid rising power disruptions across the U.S.
The technology was showcased last week during a demonstration in Calabasas, California, where real estate professionals were briefed on how EVs like the LYRIQ and ESCALADE IQ can work seamlessly with home energy systems designed by GM Energy.
At the core of the setup is a combination of home backup power, solar integration, and dedicated home battery storage. The GM Energy PowerBank, a stationary home battery, can supply nearly a full day of electricity based on average household consumption, while compatible Cadillac EVs can send power back to a properly equipped home during grid failures.
“All six electric vehicles in Cadillac’s portfolio are engineered for GM Energy’s bidirectional charging technology,” the company noted, highlighting models such as the LYRIQ, ESCALADE IQ, VISTIQ, CELESTIQ and OPTIQ.
Cadillac’s strengthening EV lineup has fueled its emergence as the top luxury EV brand in Q3, with the ESCALADE IQ recently earning MotorTrend’s 2026 SUV of the Year honor. The brand has also surpassed 50,000 LYRIQ sales, marking 13 consecutive quarters of year-over-year growth.
The rising demand for home resilience appears to align with broader housing trends. Zillow’s 2025 report cited growing interest in solar panels and whole-home battery systems among homebuyers—features increasingly relevant amid natural disasters and grid instability.
GM said homebuilders can benefit by preparing new constructions for smart energy systems, noting that installation during the building phase is both more efficient and cost-effective. The company is also collaborating with utilities such as PG&E to explore new incentive-driven energy programs.
As bidirectional EV charging and smart home energy systems become more commonplace, GM believes resilient, renewable-ready homes will become a defining feature of the next generation of housing.
