In March 2025, the U.S. implemented sweeping tariffs under the International Emergency Economic Powers Act, marking the first time such powers were invoked to levy duties on imports. Steel and aluminum tariffs surged to 25%, complemented by a new 10% global baseline tariff on a broad range of energy equipment, including critical generator components like alternators, engines, and control panels. This policy shift threatens to increase production lead times and raise material costs for generator manufacturers, with particular impact on energy projects reliant on large volumes of steel and aluminum infrastructure.

At the same time, the administration imposed a 20% tariff on Chinese imports and a 25% levy on goods from Canada and Mexico lacking USMCA compliance, creating a complex patchwork of duty rates that vary by product classification and origin. Battery Junction reports that these adjustments could add as much as 10%–20% to component costs and force many suppliers to redefine supply chains or relocate manufacturing footprints to mitigate the higher import burdens.

Wood Mackenzie’s analysis of power sector capital projects indicates that these tariff measures may elevate equipment costs by 6% to 11%, depending on technology and origin, with energy storage systems-often reliant on Chinese imports-seeing potential cost hikes exceeding 50% under aggressive trade-war scenarios. As a result, generator OEMs and project developers must adopt more flexible contracting strategies and consider domestic sourcing partnerships to absorb tariff-related risks and maintain competitive pricing structures.
