TLDR
- A $4.3 billion LFP battery manufacturing facility will be built in Lansing, Michigan through a partnership between Tesla and LG Energy Solution.
- The facility is scheduled to commence operations in 2027.
- Lithium iron phosphate (LFP) prismatic battery cells from this plant will supply Tesla’s Megapack 3 energy storage products.
- The U.S. Department of the Interior announced the agreement during the Indo-Pacific Energy Security Summit.
- While LG Energy Solution shares rose 4% following the announcement, Tesla stock declined 0.4% in pre-market activity.
A significant supply partnership between Tesla (TSLA) and South Korea-based LG Energy Solution will result in a $4.3 billion lithium iron phosphate (LFP) battery production plant in Lansing, Michigan. On Monday, the U.S. Department of the Interior made the announcement official during events connected to the Indo-Pacific Energy Security Summit.
The Michigan facility is projected to start manufacturing operations in 2027. These battery cells will supply Tesla’s Megapack 3 energy storage units, which the company produces at its Houston manufacturing site.
According to the Interior Department, the plant aims to establish a “robust domestic battery supply chain.” This objective aligns with Tesla’s strategic initiative to minimize dependence on battery manufacturers based in China.
Throughout its history, Tesla has obtained batteries from multiple sources including Panasonic, China’s CATL, and through in-house manufacturing. Chinese companies have traditionally dominated LFP chemistry production, making this agreement a significant move toward establishing domestic manufacturing capabilities.
Among the limited number of companies manufacturing LFP batteries within U.S. borders, LG Energy Solution stands out. This positioning provides a competitive edge as automotive and energy storage producers seek alternatives to Chinese supply networks amid continued tariff concerns.
Compared to cobalt-containing batteries, LFP technology offers enhanced safety profiles and extended lifespan. The lower production costs associated with LFP chemistry could enable Tesla to maintain competitive pricing for its energy storage lineup.
Reuters initially disclosed in July 2025 that LG Energy Solution secured a $4.3 billion agreement to deliver LFP batteries worldwide across a three-year period. The initial report left the customer identity and application details—whether automotive or stationary storage—undisclosed.
LG Energy Solution Stock Jumps on Confirmation
Shares of LG Energy Solution climbed 4% on Tuesday following official confirmation of the partnership. Meanwhile, Tesla stock experienced a 0.4% decline before U.S. markets opened.
The subdued response from Tesla shareholders could be attributed to ongoing challenges facing the company. Tesla shares have dropped 19% during the last three months, pressured by concerns about weakening sales momentum, declining profitability, and compressed margins.
While the S&P 500 decreased 1.7% during the same timeframe, Tesla’s downturn has been more pronounced. Index futures showed a 0.4% decline on Tuesday amid market uncertainty linked to oil price fluctuations.
Production Timeline and Location
The Lansing, Michigan location will accommodate the LFP prismatic battery cell manufacturing operation, with initial production anticipated in 2027. Output from this facility will support Tesla’s Megapack 3 assembly operations in Houston.
This arrangement enables Tesla to decrease its reliance on Chinese battery imports during a period when tariffs have increased costs and created supply chain unpredictability.
LG Energy Solution publicly acknowledged the broader $4.3 billion supply agreement last year, and Monday’s disclosure formally connects that contract to Tesla and specifies the Michigan manufacturing location.
