US home battery installations hit record high on rising electricity costs

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.
