In a significant development for South Carolina’s electric vehicle (EV) industry, Japanese battery manufacturer AESC has announced a pause in the expansion of its Florence-based EV battery plant. The decision stems from prevailing market uncertainties, including potential changes to federal EV tax credits and tariff policies. Originally, AESC planned a $1.5 billion investment to construct a second facility adjacent to its initial plant, aiming to create over 1,000 additional jobs. However, the company has now halted these expansion plans, citing the need for a more stable policy environment.
State Withdraws $111 Million in Bonds Following Project Delay
In response to AESC’s decision, the South Carolina Fiscal Accountability Authority has rescinded $111 million in bonds that were allocated to support the expansion. These funds were intended for infrastructure improvements, site preparation, and the development of a training center. Governor Henry McMaster described the withdrawal as a responsible move, emphasizing the importance of prudent financial management in light of the project’s indefinite timeline.

Initial Facility Remains on Track for 2026 Completion
Despite the pause in expansion, construction of AESC’s initial facility in Florence continues as planned. The $1.6 billion plant is expected to commence operations in 2026, employing approximately 1,620 workers. This facility will produce advanced lithium-ion battery cells for BMW’s Spartanburg assembly plant, contributing significantly to the region’s economic growth and the broader EV market.
Community Leaders Focus on Infrastructure Amid Expansion Delay
Local officials view the expansion delay as an opportunity to address existing infrastructure and housing challenges in Florence County. Efforts are underway to improve transportation networks and develop residential areas to support future industrial growth. The community remains optimistic that, once market conditions stabilize, AESC will resume its expansion plans, further solidifying Florence’s role in the EV industry.
