General Motors Company's (GM.US) Tennessee Battery Plant Strategic Turnaround: Breaking Through the Slowdown of Electric Vehicles and Betting on the Energy Storage Blue Ocean.
General Motors (GM.US) and LG Energy Solutions' joint venture, Ultium Cells LLC, will start production of energy storage batteries at its Tennessee factory next month.
General Motors Company (GM.US) and LG Energy's joint venture, Ultium Cells LLC, will start production of energy storage batteries at their Tennessee plant next month. This move aims to reactivate a factory that was idled due to General Motors Company scaling back its electric vehicle plans, and tap into the rapidly growing stationary energy storage market.
Tom Gallagher, Vice President of Operations at Ultium, said in an interview that the company will rehire around 700 workers who were temporarily laid off at the Spring Hill factory in Tennessee in January, to begin producing lithium iron phosphate batteries. These batteries will be supplied to LG, who will sell them to grid and data center customers. The factory, which started production in 2024, previously produced ternary lithium batteries for Cadillac Lyriq, Vistiq, and Honda Acura ZDX SUVs, with a workforce of up to 1350 employees when fully operational.
Gallagher stated, "We are able to quickly pivot our production capacity to new business opportunities, which sets us apart from other joint ventures." He revealed that the cost of retooling the factory was "tens of millions of dollars," and the laid-off workers are expected to return to work by the end of April.
General Motors Company and many of its peers are trying to stem the billions of dollars in losses in the electric vehicle sector by shifting joint venture factories from automotive batteries to energy storage batteries, or completely divesting from the related business. Despite US President Trump easing regulations and canceling key electric vehicle tax credits, weakening the already slowing US electric vehicle market, market forecasts show that demand for American Electric Power Company, Inc. will grow by 12% by 2030, with data centers accounting for over one-third of the increase.
Strategic Turnaround
For LG, the transformation of the Tennessee plant is a key part of its overall strategic turnaround. While LG still plans to produce automotive batteries for General Motors Company, adding production lines increases flexibility to ensure operations can continue even during periods of low demand for electric vehicles.
The South Korean battery manufacturer is transforming four other electric vehicle battery factories in North America, including two in Michigan, a joint venture factory with Honda in Ohio, and a joint venture factory with Stellantis in Windsor, Canada, all shifting to produce lithium iron phosphate batteries for stationary energy systems.
Another Ultium joint venture factory with General Motors in Ohio will continue to produce electric vehicle batteries for GM; a new factory in Arizona will also start producing electric vehicle batteries this year.
Bob Lee, President of LG Energy North America, stated that the cost of retrofitting factories to produce lithium iron phosphate batteries is typically 10% to 20% of the initial investment, as only partial equipment adjustments are needed.
UBS Group AG analyst Tim Bush pointed out that the US market is a crucial source of growth for LG, unlike Europe, where regulatory barriers are in place. Bush said, "This is a big bright spot in terms of revenue and profit growth." UBS Group AG stated that LG and its energy system customers may benefit from federal subsidies covering about 60% of energy system costs, including the 45X battery production tax credit and the 48e investment tax credit preserved in President Trump's budget proposal.
Power Hungry
Tristan Doherty, Chief Product Officer of LG's stationary energy systems integration division, Vertech, stated that even with the slowdown in the AI-driven data center construction boom, there is enough power demand in North America to absorb LG's existing production capacity.
Doherty, in an interview at LG's Windsor plant, said, "Being able to transform these facilities in less than a year means we can quickly respond and actually achieve the capacity. We will supply domestically produced cells to most markets in the US."
UBS Group AG predicts that Korean manufacturers' combined market share in the US utility-scale market could increase from less than 10% in 2025 to over 50% by 2027.
For General Motors Company, the shift towards energy storage systems is only temporary. General Motors Company spokesperson Stu Fowle stated that the value of converting the factory to produce energy storage cells is to bring back furloughed workers and maintain the factory's capacity to produce automotive batteries.
In the future, General Motors Company plans to use rich manganese lithium batteries produced by LG. Both companies are betting that rich manganese lithium batteries can compete on cost with lithium iron phosphate batteries and provide superior performance. General Motors Company has not yet specified a US production location, but the Spring Hill factory has the capability to produce rich manganese lithium batteries.
