How do tariffs directly impact energy storage project costs?

Tariffs apply to battery cells, modules, balance-of-system components, and critical minerals used in energy storage systems. Tariff increases flow directly into project capex; a 15-25% tariff on imported battery components can add hundreds of thousands of dollars to megawatt-scale projects. Projects with fixed-price contracts bear tariff risk if costs exceed contract thresholds.

What should procurement teams do now to prepare for 2026 tariff changes?

Conduct tariff scenario planning immediately. Map supplier geographies and tariff exposures by component. Establish baseline costs with current tariff assumptions and model 10-25% upside scenarios. Accelerate procurement of long-lead items (battery cells, power electronics) before tariff changes take effect. Diversify supplier locations to balance tariff exposure across jurisdictions.

Which energy storage supply chain components face the highest tariff risk?

Battery cells and modules typically face the steepest tariffs, especially if sourced from non-FTA jurisdictions. Critical minerals (lithium, cobalt, nickel) face trade restrictions or tariffs. Power electronics and inverters may also be tariffed. Domestic content or FTA-compliant sourcing can reduce exposure, but availability and pricing may limit options.

How can companies mitigate tariff risk in energy storage procurement?

Options include: (1) securing FTA-compliant supplier quotations to lock in lower tariff rates; (2) negotiating tariff adjustment clauses in long-term contracts; (3) qualifying domestic suppliers where viable; (4) implementing strategic inventory buys ahead of known tariff changes; (5) evaluating alternative battery chemistries or technologies with different tariff profiles.

What is the timeline for tariff decisions affecting 2026 energy storage projects?

Morgan Lewis outlines a 2026 outlook, suggesting tariff policy decisions will likely be finalized or announced in 2025. Supply chain teams should monitor trade policy announcements, tariff reviews, and regulatory guidance through 2025 to finalize procurement strategy by Q3 2025 for 2026 project execution.

The signal

Morgan Lewis has published forward-looking analysis on tariff and trade policy risks that will materially impact energy storage projects entering 2026. The outlook highlights structural uncertainty in tariff regimes affecting battery components, critical minerals, and integrated energy storage systems—key inputs to renewable energy deployment and grid modernization initiatives across North America. For supply chain professionals, this analysis signals the need for immediate procurement strategy recalibration.

Energy storage projects operate on tight margin assumptions; tariff volatility directly threatens project economics, timelines, and sourcing flexibility. Companies sourcing batteries, inverters, and balance-of-system components must model tariff scenarios, evaluate geographic diversification of suppliers, and accelerate long-lead-item procurement timelines ahead of any 2026 tariff changes. The broader implication is that energy infrastructure buildout—critical to decarbonization and grid stability—faces policy-driven cost inflation and supply chain fragmentation.

Procurement teams should engage tariff counsel early, establish tariff-inclusive cost baselines, and build contractual flexibility for tariff pass-through or supplier qualification pivots. Failure to anticipate tariff impacts could delay project timelines, erode margins, or force unplanned sourcing changes mid-project.
