Policy Update: What the Latest ITC Adders Mean for Your Project

Domestic content, energy community, and low-income adders can push the Investment Tax Credit well above the base rate. Knowing which your project qualifies for can swing returns by double digits.

The base credit and the adders

The Investment Tax Credit (ITC) remains the single most important driver of solar and storage project economics. Beyond the base credit, a series of "adders" can stack to materially increase the value of a qualifying project.

Domestic content adder. Using qualifying U.S.-manufactured equipment can add 10 percentage points.
Energy community adder. Projects sited in former fossil-fuel communities or brownfields can add another 10 points.
Low-income adder. Projects serving low-income communities or housing can qualify for additional credit allocations.

Why it matters

Stacking adders can lift an effective credit well above the base level, dramatically improving payback and IRR. Our Faith Community project in metro Atlanta, for example, targets a 40% ITC through domestic content qualification.

Plan early

Eligibility hinges on documentation and procurement decisions made early in development. Engaging tax and engineering teams before equipment selection ensures you capture every credit your project is entitled to.
