Driven by state incentives seeking to offset rising residential electricity costs, American homeowners have adopted home batteries in record-breaking numbers as early as 2026. This trend could also unlock more flexible energy supplies for power grid operators and even AI data centers.
New home battery installations reached a record 673 megawatts of energy storage in the first quarter of 2026, according to the U.S. Energy Information Administration. The trend was driven by states with high electricity prices that have implemented policies to encourage home battery installation, Bloomberg News reports.
This residential battery trend is a natural next step for states that have already successfully promoted rooftop solar adoption among homeowners, given how batteries enable homeowners to use stored solar energy at night. California and Hawaii account for the majority of new residential battery storage, while Texas and Arizona have also seen significantly higher numbers of installations.
California encourages homeowners with solar panels to install batteries by offering better prices for residential electricity exported to the grid after sunset, Bloomberg reports. Hawaii offers a one-time payment of $400 for each kilowatt of battery storage installed by homeowners.
However, record-breaking home battery installations have coincided with a slowdown in residential installations of solar panels — the Trump administration and the Republican-driven One Big Beautiful bill have eliminated the 30 percent federal solar tax credit for homeowners. Still, U.S. electricity generation from solar power continues to grow and even overtook coal-fired generation in April.
The battery installation spree also coincides with rising electricity costs for US residential customers. The latest data from the Energy Information Administration shows the nationwide average of residential electricity costs in April 2026 is set to increase by more than 7 percent compared to electricity costs in April 2025. So homeowners with smart home battery-management systems can benefit from storing energy when electricity prices are lowest and draining them during peak demand periods.
