Qualified Expenses for Commercial Energy Storage Systems
In the United States, commercial energy storage systems can qualify for tax credits under Section 48 of the Internal Revenue Code. These credits are part of the broader energy storage incentives aimed at encouraging the development and integration of various energy storage technologies.
Eligible Expenses
Section 48 Investment Tax Credit (ITC):
- Base Credit: The base value of the tax credit is 6% of the project’s qualifying energy costs.
- Enhanced Credit: For projects meeting specific requirements like prevailing wage and apprenticeship standards (PWA), the credit can increase to 30% of the project costs. Additional bonus adders can further boost the credit to up to 50% of the project’s cost.
Eligible Projects:
- Energy storage systems, including but not limited to batteries, are eligible for these credits. This includes both standalone energy storage projects and those integrated with other renewable energy systems.
- For larger projects (over 1 MW), the enhanced credit applies if PWA standards are met.
Qualification Criteria
- Prevailing Wage and Apprenticeship Requirements (PWA): To qualify for the enhanced 30% ITC, projects must adhere to specific PWA standards. This involves ensuring workers are paid prevailing wages and that a certain percentage of apprentices are involved in the construction process.
- Placed in Service Date: The project must be placed in service according to IRS definitions, which means the equipment must be ready for its intended use, regardless of when it actually starts operating at full capacity.
Bonus Adders
Additional credits may be available for energy storage projects that provide specific benefits, such as:
- Capacity Services: Compensation for the capacity to supply power during peak demand.
- Ancillary Services: Provision of services like frequency regulation.
- Congestion Relief: Helping manage power flow to prevent grid congestion.
These bonus adders can significantly increase the project’s overall viability by enhancing the total tax credit value.
