Do you worry that increased AI energy consumption will drive up electricity costs for your household?
Energy storage costs in the United States are expected to fall by 15% to 30% by 2030, even as current supply chain bottlenecks inflate domestic prices. This forecast arrives amid a massive surge in demand for lithium-ion battery backup systems powering AI data centers.
Why it matters
Rising demand for battery infrastructure has tightened supply, but global market shifts like stabilized lithium prices and new trade policies are set to drive down costs. These price adjustments will ultimately influence the long-term affordability of home energy storage and electric vehicle power systems.
Global shipments reached 230 GWh in Q2 2026, while U.S. imports for AI battery backup units surged 131% year-over-year. Currently, 11% of projected 2026 U.S. battery production capacity faces potential delays into 2027.
The players
CATL
A dominant global battery manufacturer holding over 25% of the total shipment market share.
LGES
A major battery developer currently expanding production capacity with 33 GWh across three new factories.
The details
Battery manufacturers are currently transitioning production from standard prismatic cells to larger, more cost-efficient formats to scale capacity. Concurrently, producers are anchoring domestic facilities in the U.S. to comply with tax credit requirements under Section 45X, which is expected to help offset import-related price pressures. As China moves to end its value-added tax rebate on battery exports, global market pricing for lithium-ion materials is stabilizing.
Timeline
Q2 2026: Global lithium-ion shipments hit 230 GWh.
January to July 2026: Imports for AI data center battery backup systems surged.
January 1, 2027: China eliminates its remaining value-added tax battery rebate.
2030: The projected deadline for U.S. energy storage price declines of 15% to 30%.
The Home Front
The transition to domestic production is a direct response to the federal incentives established under the Section 45X tax credit. These policies aim to insulate the U.S. market from the volatility of global trade barriers and fluctuating import costs.
Homeowners planning to invest in battery backup systems for solar installations or emergency power should track how these macro-level supply shifts influence local installer quotes. Keep an eye on the 2027 shift in international trade policy, as it may influence the long-term price trends for battery technology.
The takeaway
While domestic battery costs are currently elevated due to supply bottlenecks, the long-term outlook suggests significant savings for home storage by 2030. Homeowners considering high-capacity battery systems should monitor market stabilization as domestic manufacturing capacity continues to scale.
