Exploring Battery Energy Storage Systems (BESS) under the Inflation Reduction Act 

Battery energy storage systems (BESS) have received significant advancement in the United States due to the implementation of the Inflation Reduction Act (IRA), opening new opportunities for their development. This groundbreaking legislation introduces unprecedented economic benefits for standalone storage systems by making them eligible for a 30% investment tax credit (ITC), with the potential to increase to 70% through additional incentives. Historically, federal tax credits were only available for storage systems that were paired with renewable energy generation, such as solar power. However, the IRA has extended the eligibility of tax credits to standalone storage systems, which is anticipated to unleash a remarkable surge in storage investments. This landmark development holds immense potential, opening new avenues for investment and accelerating the transition towards a sustainable and reliable energy grid. 

Enhanced Investment Opportunities 

The IRA provides the investing environment with much needed certainty by extending the duration of ITCs. The increases and expansions of ITCs given through the IRA are now guaranteed through 2032 rather than being subject to temporary renewals. This more extensive timetable gives investors and developers the chance to strategically plan and maximize their returns. Additionally, the definition of project costs eligible for the tax credit has been expanded to include interconnection, microgrid controllers, and a broader range of components commonly used in clean energy systems. This can increase tax credit eligibility and accelerate project development. 


Leveraging Incentives 

Energy storage projects must adhere to labor standards in order to fully benefit from the tax incentives provided under the IRA. These criteria make sure that registered apprenticeship standards are followed and that prevailing salaries are paid. If a project satisfies these requirements, it may be further enhanced by three additional incentives: domestic content, energy communities, and low-medium income (LMI) initiatives. 

The domestic content incentive incentivizes the utilization of equipment and materials produced domestically, aligning with the broader national objective of promoting local manufacturing. The energy communities incentive offers benefits for projects located in areas associated with fossil fuel activities, brownfield sites, or regions that have previously experienced direct employment or tax revenue from such activities. BESS projects can also be integrated with wind or solar installations in low-income communities or on tribal land to receive extra incentives, fostering inclusivity and supporting the clean energy transition in underserved areas. This means institutional investor clients can benefit from investing in projects that promote local manufacturing, support energy communities and foster inclusivity in clean energy initiatives.

Simplified Processes and Flexible Options  

The IRA maintains the existing structure of the ITC for energy storage, including a five-year period for modified accelerated cost recovery system, which accelerates depreciation in the early years of asset life. Notably, the law introduces the transferability of certain tax credits, allowing for more streamlined investment structures. This increases flexibility for investors and enables developers to monetize tax credits more efficiently, even without significant tax liabilities.

Looking Ahead 

Energy storage deployment will considerably boost grid stability and carbon reduction as it continues to grow. The industry is anticipating further guidance on some specific details for BESS, which will provide a clearer understanding of the requirements and opportunities under the new legislation. 


The IRA presents a transformative opportunity for battery energy storage systems in the United States. The expanded tax credits, combined with a longer-term guarantee, create an environment conducive to increased investment and deployment of energy storage projects. By leveraging these incentives, stakeholders can drive the clean energy transition, enhance grid reliability, and contribute to a sustainable, carbon-free future. The IRA paves the way for the energy storage industry to play a vital role in achieving ambitious renewable energy goals.
