Tesla signs a $4.3 billion battery supply deal with LG
Tesla has formalized a landmark $4.3 billion agreement with LG Energy Solution to procure U.S.-made lithium iron phosphate (LFP) batteries for its energy storage systems, signaling a key reduction in reliance on Chinese suppliers.
The batteries will be produced at LG’s Michigan facility and supplied from 2027 to 2030. The move underscores Tesla’s pivot toward domestic sourcing to mitigate tariff risks and support its expanding energy storage operations.

The agreement runs for three years with optional extensions
This supply agreement officially spans from August 2027 through July 2030, with provisions allowing for an extension of up to seven additional years, provided that both parties agree. This structure provides Tesla with the flexibility to scale its supply as demand evolves, ensuring a modulated and secure battery source for its growing energy business.
The arrangement introduces resilience into Tesla’s sourcing strategy while ensuring long-term continuity.

U.S.-made LFP cells help Tesla sidestep China tariffs
Amid rising import duties on Chinese lithium iron phosphate cells, Tesla is shifting to U.S.-made LFP batteries to protect its energy storage business. CFO Vaibhav Taneja previously noted that tariffs had an “outsized” impact on that division.
By tapping LG’s Michigan facility, Tesla is shielding this vital line of business from future tariff shocks, aligning operations with domestic trade policy while ensuring smoother cost management.

LG’s Michigan plant gives U.S. battery supply a head start
LG Energy Solution began ramping lithium iron phosphate production at its Michigan facility by May 2025. With few competitors offering mass-scale U.S. LFP capacity, this gives Tesla timely access to reliable domestic supply.
The Michigan plant’s early readiness positions LG as a strategic partner, allowing Tesla to gain traction in energy storage deployment without tariff-related delays from overseas sourcing.

The deal buffers Tesla against energy-storage demand swings
Industry analysis suggests this multi-year deal acts as a strategic hedge for Tesla against volatile energy storage demand. Securing a dedicated battery supply ensures that even if the power grid or AI-related demand fluctuates, Tesla won’t face supply disruptions.
This foresight enables stable capacity planning across Megapack and Powerwall production lines and ensures operational continuity if demand shifts or tariff conditions change.

Batteries are designated for energy storage, not electric vehicles
The contract specifies LFP cells will be used exclusively in Tesla’s energy storage products, such as Megapack and Powerwall, not in its vehicle lines.
This allocation boosts Tesla’s grid and renewable energy infrastructure strategy, offering insulation from vehicle business disruptions while expanding its reputation as a comprehensive clean energy solutions provider.

Tesla prioritizes energy-storage growth while maintaining EV leadership
Despite the emphasis on energy storage, Tesla’s core EV operations remain integral to its business model. The LG deal helps scale energy infrastructure, but Tesla continues to invest in automotive R&D, new model programs, and gigafactory expansion.
Analysts emphasize that energy storage isn’t replacing EVs, it’s bolstering Tesla’s long-term resilience across both markets and positioning the company for diversified growth.

Bloomberg and Reuters simultaneously broke the LG-Tesla story
The $4.3 billion battery supply deal with LG was initially reported by Bloomberg on July 29, 2025, followed by Reuters on July 30. LG’s regulatory filings confirmed the contract but withheld customer identity; subsequent reporting quickly linked Tesla as the purchaser.
Together, both media outlets verified the agreement and publicized the details, offering transparent coverage of a major U.S.–South Korea energy industry development.

LG’s U.S. LFP output offers a clear strategic advantage
Analysts highlight LG’s Michigan output as a first mover in U.S. LFP production. The plant is set to reach 30 GWh annual capacity by the end of 2026, something no other supplier has achieved domestically.
For Tesla, partnering with LG grants exclusive access to reliable, scalable, tariff-safe supply, differentiating the automaker’s domestic energy sourcing from competitors still dependent on imports.

LFP chemistry supports affordability and grid durability
Lithium iron phosphate batteries are valued for their enhanced durability, safety, and cost-effectiveness over alternatives. While they offer lower energy density, their longevity and reliability make them ideal for stationary and grid-scale storage.
This aligns with Tesla’s goal to deploy dependable, affordable energy storage systems, facilitating both renewable integration and infrastructure resilience.

Tesla exploring in-house LFP cell production in Nevada amid ramp uncertainty
Tesla is exploring LFP cell production in Nevada, repurposing equipment and planning a modest pilot facility. However, reliable sources indicate timelines are still tentative, and commercial-scale production is not confirmed. The Nevada effort appears designed to supplement, not replace, the LG contract, providing potential flexibility in future battery sourcing.
Industry observers note that Tesla’s in-house LFP capabilities remain an experimental hedge at this stage.

The deal represents nearly 25% of LG’s annual revenue
Industry analysts estimate that Tesla’s $4.3 billion agreement with LG Energy Solution amounts to roughly one-quarter of LG’s projected annual battery sales, based on the company’s 2024 revenue figures.
This percentage underscores the deal’s substantial impact on LG’s financial outlook and influence in the U.S. clean energy supply chain, while also highlighting Tesla’s scale in securing long-term, high-volume battery partnerships.

Tesla’s energy division becomes a critical growth segment
Tesla’s energy generation and storage division recorded over $2.8 billion in Q2 2025 revenue, contributing more than 10% of total company sales. This marks a significant shift, as the segment’s growth rate is outpacing the automotive business.
With increased demand for Megapack installations and Powerwall units, Tesla is positioning its energy division as a key revenue pillar amid potential slowdowns in global EV demand.
