US Government Confirms Tesla and LG Energy Solution’s $4.3 Billion Battery Deal

WASHINGTON, March 16 (Reuters) – ⁠The ⁠U.S. government on Monday ⁠said electric vehicle maker Tesla and South ​Korea’s LG Energy Solution had signed a supply agreement ‌to build a $4.3 billion ‌lithium iron phosphate (LFP) prismatic battery cell manufacturing facility ⁠in ⁠Lansing, Michigan, with an expected production launch in 2027.

“American-made ​cells will power Tesla’s Megapack 3 energy storage systems produced in Houston, creating a robust domestic battery supply chain,” ​the U.S. Department of the Interior said in a statement ⁠on ⁠Monday.

The agreement was part ⁠of ​a broader statement on deals highlighted by President Donald Trump’s ​administration from ⁠the Indo-Pacific Energy Security Summit.

A source told Reuters in July that LG Energy Solution had signed a $4.3 billion deal to supply Tesla with energy storage system ⁠batteries as the U.S. company looked to reduce its reliance ⁠on Chinese imports due to tariffs.

At the time, the South Korean company said it had signed a $4.3 billion contract to supply LFP batteries over three years globally, without identifying the customer or saying if they would be used in vehicles or energy-storage systems.

LG Energy Solution is one of ⁠the few producers of LFP batteries in the U.S. The LFP battery chemistry has long been dominated by Chinese rivals that have little presence in ​the U.S. market.
