ARRAY Reaches 100% Domestic Content Milestone

Get in touch with an ARRAY representative to learn more

ARRAY Technologies announced that we will supply trackers for a 200 megawatt (MWac) solar project that meets 100% of the domestic content Assigned Cost Percentage (ACP) under the U.S. Treasury Department’s latest guidance (Notice 2025-08) issued in January 2025. The domestic content trackers will be supplied to the Emerald Green Solar project in Indiana, which is being developed by ENGIE North America (ENGIE).

Engie is thrilled that domestically produced solar trackers will be deployed at our Emerald Green Solar project in Howard County, Indiana. The ability to work with a U.S. manufacturer of qualified domestic content components for this 200 MWac project supports ENGIE’s commitment to delivering local economic benefits in the states and communities where we operate as well as in the wider American economy. The fact that the steel used in ENGIE’s largest energy project in Indiana will include torque tube and steel rolled locally in the state and installed by some of the more than 250 construction workers that will build the project really reflects the local nature of renewable energy production in the U.S.

Emerald Green Project

Kicking off this announcement is the Emerald Green Project. This project represents ARRAY’s first full-site deployment of its 100% domestic content tracker solution, which enables developers to qualify for the maximum 28.7% Assigned Cost Percentage (ACP)—including the additional 9.4% production ACP available exclusively to projects using trackers with only domestic content manufactured product components.

The project, located just outside Indianapolis, Indiana, will be built entirely with ARRAY’s domestic content tracker systems. To validate full compliance with federal guidelines, ARRAY partnered with a third-party tax and advisory firm to analyze its manufacturing processes and supply chain.
