Sen. Martin Heinrich, D-New Mexico, Sen. Susan Collins, R-Maine, and 10 other senators have introduced legislation to amend the existing investment tax credit (ITC) law for solar energy to include the deployment of energy storage. The Energy Storage Tax Incentive and Deployment Act of 2021 (S. 627) would add storage to ITC-eligible resources. An identical bill (H.R. 1684) was introduced in the House of Representatives by Rep. Michael Doyle, D-Pennsylvania, Earl Blumenauer, D-Oregon, and Vern Buchanan, R-Florida. The legislation would apply to property placed in service or expenditures paid or incurred after Dec. 31, 2020.
