SUMMARYUS homeowners installed a record 673 megawatts of home battery storage in the first quarter of 2026, driven by state incentives and rising electricity bills. California and Hawaii accounted for most of the growth, with Texas and Arizona also seeing sharp increases. The expansion could give grid operators and AI data centers a more flexible electricity supply.
US homeowners have embraced home batteries in record-breaking numbers in early 2026, spurred on by state incentives while seeking to offset rising residential electricity costs. The trend could even unlock a more flexible energy supply 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 US Energy Information Administration. That trend was driven by states with high electricity prices that have implemented policies to incentivize home battery installation, Bloomberg News reported.
This residential battery trend stands out as a natural next step for states that have already successfully boosted rooftop solar adoption among homeowners, given how batteries enable homeowners to use stored solar energy at night. California and Hawaii accounted for the majority of new residential battery storage, while Texas and Arizona also saw significantly higher numbers of installations.
