The Investment Tax Credit (ITC) and Production Tax Credit (PTC) are two of the most used incentives driving the growth of renewable energy in the United States. As the energy sector continues to evolve, what dual-use property has become is increasingly relevant for project developers and investors seeking to maximize their tax benefits. This article explores dual-use property in the context of the ITC and PTC, examining recent regulatory changes and their effect on the renewable energy industry.
Understanding Dual Use Property
Dual-use property refers to equipment or facilities that serve multiple purposes, including those that qualify as renewable energy generators and those that do not qualify. In the context of renewable energy tax credits, dual-use property typically involves systems that derive energy from both qualifying sources (solar, wind, or geothermal) and non-qualifying sources (natural gas, coal-fired).
ITC Perspective
The Investment Tax Credit, codified in Section 48 of the Internal Revenue Code, provides a tax credit for investments in certain types of energy property. Historically, the ITC has had strict rules regarding dual-use property, which have recently been updated to reflect changes in technology and industry practices.
Under the previous regulations, a property was only eligible for the ITC if at least 75% of its total energy input came from qualifying sources as measured in the annual testing period. This rule, known as the "75% cliff," posed challenges for many renewable energy projects, particularly those integrating energy storage or utilizing hybrid systems. Recent regulations, issued in November 2023, have significantly relaxed this requirement. The new rules reduce the threshold from 75% to 50%.
This change means that dual-use property can now qualify for the ITC if its use of energy from non-qualifying sources does not exceed 50% of its total energy input during an annual measuring period.
Furthermore, the proposed regulations allow for more flexibility in calculating qualifying energy inputs. Taxpayers can now aggregate energy inputs from multiple qualifying sources when determining whether the 50% threshold is met. This change is particularly beneficial for complex renewable energy systems that may incorporate multiple technologies. For dual-use property that meets the 50% threshold, the ITC-eligible basis is prorated based on the percentage of qualifying energy use. For example, if a system derives 75% of its energy from qualifying sources, 75% of its eligible basis would qualify for the ITC.
PTC Perspective
The Production Tax Credit, outlined in Section 45 of the Internal Revenue Code, provides a per-kilowatt-hour tax credit for electricity generated from qualifying renewable sources. The PTC has traditionally been less concerned with dual-use property issues, as it is based on actual electricity production rather than capital investment.
However, the concept of dual-use property becomes relevant for PTC-eligible facilities that are co-located with ITC-eligible energy storage or other equipment. The proposed regulations provide clarification on this issue, confirming that a PTC can be claimed on the electricity output from a qualified facility eligible for the PTC while an ITC can be claimed on co-located energy storage technology.
This clarification is particularly significant for the growing number of hybrid renewable energy projects that combine generation facilities (e.g., wind or solar farms) with energy storage systems. It allows project developers to optimize their tax credit strategy by claiming the PTC on generation and the ITC on storage, even when these components share certain equipment or infrastructure.
Project Development and Financing
The updated rules on dual-use property have several important implications for renewable energy project development and financing:
-
Increased Flexibility in Project Design
Greater flexibility for project developers to design systems that incorporate multiple energy sources or technologies. This can lead to more efficient and resilient energy systems that better meet the needs of the grid and end-users.
-
Enhanced Viability of Hybrid Projects
Hybrid projects that combine multiple renewable energy technologies or integrate energy storage are becoming increasingly common. The new rules make it easier to claim tax credits on these complex systems.
-
Simplified Compliance for Energy Storage
The clarification regarding co-located PTC and ITC facilities is particularly beneficial for projects incorporating energy storage. It eliminates previous concerns about grid-charging limitations on ITC-eligible storage systems.
-
Improved Economics for Certain Projects
The ability to claim tax credits on a larger portion of dual-use property can improve the overall economics of renewable energy projects. This may make some previously marginal projects more attractive.
-
Potential for New Technology Integration
The integration of emerging technologies or innovative system designs that were previously challenging to accommodate within the tax credit framework may now be reasonable to use.
While the updated rules on dual-use property generally provide more opportunities for renewable energy projects, they also introduce some new considerations:
-
Project owners must carefully measure and document the energy inputs from qualifying and non-qualifying sources to ensure compliance with the 50% threshold. This may require monitoring systems and rigorous record-keeping practices.
-
The ITC is subject to recapture if the use of non-qualifying energy sources exceeds the 50% threshold during the five-year recapture period. Project operators must be vigilant to maintain compliance and avoid potential tax consequences.
-
The rules regarding separate ownership of components within an energy property add complexity to project structuring. Careful consideration must be given to ownership arrangements to ensure tax credit eligibility.
-
Project developers and investors should consider how the dual-use property rules interact with other aspects of the ITC, such as the prevailing wage and apprenticeship requirements, domestic content bonus, and energy community bonus.
Future Outlook
As the renewable energy sector evolves, rules surrounding dual-use property will continue to be refined. Areas that may see further development include:
-
Emerging Technologies
As new renewable energy technologies emerge, there may be a need for additional guidance on how they fit within the dual-use property framework.
-
Measurement Methodologies
The IRS may provide more detailed guidance on acceptable methodologies for measuring and documenting energy inputs from various sources.
-
Grid Modernization Efforts
As the electrical grid becomes more complex and interactive, the concept of dual-use property may need to evolve to accommodate new operations.
-
Legislative Changes
Future legislation, such as potential extensions or modifications to the ITC and PTC, could further impact the treatment of dual-use property.
Project developers, investors, and other stakeholders in the renewable energy sector should closely monitor developments and consider how the new dual-use property rules may impact their project planning and investment strategies. As with any complex tax matter, it's advisable to consult with qualified tax professionals to ensure compliance.
The updated rules on dual-use property represent a significant evolution in the renewable energy tax credit landscape. These changes have the potential to accelerate the deployment of advanced renewable energy systems and support the transition to a cleaner, more resilient energy infrastructure. As the renewable energy industry changes market conditions and policy frameworks, the concept of dual-use property will likely remain an important consideration in the pursuit of a sustainable energy future.
