Congress is considering an investment tax credit (ITC) for standalone energy storage systems, which could significantly accelerate energy storage deployment across the U.S. While negotiations are ongoing, there is significant support for a storage ITC that would apply to projects beginning construction in 2022.

An investment tax credit (ITC) reduces an entity’s tax liability by a specified percentage of the ITC-eligible investment. When offered as a direct, immediate payment (“direct-pay” option), as is currently proposed for the storage ITC, it is also available to tax-exempt entities. The federal ITC for solar energy, introduced in 2006, was a major catalyst for the tremendous growth of solar in the U.S.
Currently, energy storage is only eligible for a federal ITC when it is paired with solar. A “standalone storage ITC” (or simply a “storage ITC”) would make investments in standalone storage systems ITC-eligible and likely stimulate additional investment in energy storage projects. Analyst firm Wood Mackenzie predicts that a 30% storage ITC would increase U.S.-wide energy storage deployments by 20% or more.
More investment in energy storage increases the benefits storage can provide to energy users and the grid. Energy storage is enabling hospitals and critical facilities to function despite power outages; schools and businesses to save on their electricity bills; and electric utilities to add more intermittent renewable energy onto their systems. A storage ITC would also create jobs and strengthen America’s energy storage industry.
A storage ITC would improve project economics across the board. Projects that are already economically attractive would become more so, while other projects would become viable in both new and existing markets. Wood Mackenzie estimates that a 30% storage ITC would improve project internal rates of return (IRRs) by roughly 5%.
Existing energy storage markets in California, Hawaii, Massachusetts, and New York would likely expand, while storage deployments in emerging markets would likely accelerate nationwide.
Support for a storage ITC, always popular among both political parties, is now stronger than ever. A storage ITC has been included in draft legislation in both houses of Congress, and the White House has consistently voiced its support. It is being discussed as a 30% incentive with a direct-pay option for energy storage projects commencing construction on or after January 1, 2022. If passed, it is expected to be available for at least four years (through 2025) but possibly up to 10 (through 2031).
The expected path forward for a storage ITC is via the “budget reconciliation” process. (The bipartisan infrastructure bill, passed by the Senate on August 10, includes only “hard” infrastructure projects such as roads, bridges, and water facilities.) Budget reconciliation allows matters affecting federal spending and revenue to pass the Senate with 51 votes rather than 60.
The Senate passed a budget resolution on August 11, which the House will take up the week of August 23. Budget reconciliation will begin in the Senate once both chambers have approved the resolution. Senate Democrats’ “reconciliation plan,” which is widely expected to include a standalone storage ITC, has yet to be drafted; committees are expected to submit reconciliation legislation by September 15. Timing for passage of the reconciliation package is late Q3 to early Q4.
A storage ITC would make both standalone storage and solar plus storage projects more appealing, and would be incremental to some state incentives as well as the 10-30% utility bill savings that energy storage systems typically provide. The ITC would also enable organizations to get more value from efforts to avoid power outages, reduce GHG emissions, and demonstrate sustainability and ESG leadership.

A storage ITC would create a tremendous opportunity to retrofit existing solar systems with energy storage and offer a new value proposition to customers you already know well. It would also provide critical support to the energy storage industry and significantly expand partnership opportunities for solar developers and storage providers for years to come.
