Investment Tax Credit (ITC)
The Investment Tax Credit provides a federal incentive for commercial and large-scale battery storage projects, including standalone systems with a minimum capacity of 5 kWh. As updated by the Inflation Reduction Act and preserved under the One Big Beautiful Bill, battery storage projects are not subject to the accelerated construction-start deadlines that now apply to solar and wind. Instead, they remain eligible for the full 30% ITC if construction begins before 2033, with phase-downs beginning in 2034 and elimination after 2035. However, domestic content requirements and foreign entity sourcing restrictions still apply starting December 31, 2025
