Do you worry that increased AI energy consumption will drive up electricity costs for your household?

U.S. energy storage prices are expected to decline between 15% and 30% by 2030, despite current supply chain bottlenecks and trade barriers. The forecast arrives as AI infrastructure development triggers a significant increase in demand for lithium-ion battery backup systems.

Why it matters

Domestic battery storage costs remain elevated compared to global prices due to trade constraints and manufacturing shifts. Stabilizing the cost of these systems is critical to supporting the rapid growth of AI data centers across the United States.

Global lithium-ion battery shipments reached 230 GWh in Q2 2026, with CATL capturing over 25% of that volume. Meanwhile, U.S. imports for AI data center battery units totaled 5,529 metric tons between January and July 2026.

The players

CATL

CATL is a major Chinese battery manufacturer that accounted for over 25% of global shipment volumes in the second quarter of 2026.

LGES

LGES is a battery producer currently managing 33 GWh of capacity expansion across three of its factory sites.

Samsung SDI

Samsung SDI is a technology firm that operates an LFP cathode production line located in Indiana.

The details

Manufacturers are currently retooling production lines from standard prismatic cells to larger formats to optimize costs and meet Section 45X tax credit requirements. Although global lithium prices have stabilized near $20 per kilogram, approximately 11% of planned 2026 U.S. battery production capacity faces potential delays into 2027.

Global lithium-ion battery shipments reached 230 GWh during Q2 2026.
Imports for AI backup systems surged between January and July 2026.
China will eliminate its remaining battery value-added tax rebate on January 1, 2027.
Domestic energy storage prices are projected to decline through 2030.

Roadmap

The transition to domestic battery production is heavily anchored by compliance with Section 45X of the Inflation Reduction Act. This policy forces manufacturers to balance the need for cheaper, globally sourced battery formats against the requirement for localized production to capture tax credits.

Lower battery storage costs will eventually translate into more affordable implementation of backup power systems for critical infrastructure and private sector technology projects. Drivers and consumers should expect these price adjustments to influence the long-term cost of electric vehicle charging infrastructure.

The takeaway

The maturation of the domestic battery market depends on reconciling trade policy with large-scale production requirements. Readers and industry stakeholders should monitor the scheduled 2027 change in Chinese tax rebates as a primary indicator of future import pricing trends.
