US Finalizes 45X Tax Credits to Boost Clean Energy Manufacturing

The US Department of the Treasury and Internal Revenue Service has finalized rules for the 45X advanced manufacturing tax credit, an initiative under the Inflation Reduction Act of 2022. The credit is designed to spur investment in domestic manufacturing for components used in wind, solar, and battery systems, reducing reliance on imports and strengthening the US clean energy supply chain.

Key Highlights of the 45X Tax Credit

• Incentives for Components:

- Solar cells: 4¢/W

- Solar modules: 7¢/W

- Photovoltaic wafers: $12/m²

- Wind turbine blades: 2¢/blade

- Battery cells: $35/kWh

• Mineral Production Tax Credit: US producers of critical minerals like aluminum, cobalt, graphite, lithium, and nickel can claim 10% of production costs.

Phased Expiry of Credits

The credits will begin phasing out after 2030:

• 75% of the original value for components sold in 2030.
• 50% for 2031.
• Expiring completely after 2033.

Impact on the Renewable Sector

The 45X credit is expected to bolster the US solar industry, which has long relied on imported photovoltaic cells and modules, primarily from China and Southeast Asia. These imports are subject to tariffs and trade investigations, creating additional hurdles for developers.

US-based companies such as First Solar, Enel, and Qcells have already announced plans to establish manufacturing facilities in the US, citing the credits as a critical driver.

A Step Towards Energy Independence

Energy Secretary Jennifer Granholm highlighted the broader implications of the credits:

"These final rules will help strengthen energy dominance while reducing emissions and leveling the playing field for US companies."

With solar and wind energy demand continuing to grow, the 45X tax credit represents a significant step in building a robust, domestic clean energy manufacturing ecosystem, ensuring the US remains competitive in the global energy transition.
