Proterra Congratulates LG Energy Solution on Announcement of Arizona Battery Manufacturing Complex

The two companies previously announced a long-term supply agreement for cylindrical cells manufactured at a LG Energy Solution U.S. facility

The Manufacturing Complex is expected to include dedicated battery cell capacity for Proterra-manufactured, USMCA-compliant commercial EV battery systems

BURLINGAME, Calif., March 24, 2023 (GLOBE NEWSWIRE) -- Proterra Inc (NASDAQ: PTRA), a leading innovator in commercial vehicle electrification technology, today congratulated LG Energy Solution on its announcement that it will construct a battery manufacturing complex in Queen Creek, Arizona.

Proterra and LG Energy Solution previously announced a long-term supply agreement to provide Proterra with cylindrical cells produced at an LG Energy Solution battery cell manufacturing plant in the United States. Today’s announcement by LG Energy Solution regarding the future Queen Creek, Arizona complex represents a major step forward to secure Proterra access to multiple gigawatt hours of dedicated U.S.-manufactured battery cell capacity on an annual basis.

“As an American technology leader, Proterra is proud to be part of LG Energy Solution’s decision to bring battery cell manufacturing to the United States,” said Gareth Joyce, Proterra CEO. “Today’s announcement helps to further the United States’ commitment to develop domestic production of EV batteries as well as Proterra’s mission to power a better, more sustainable world.”

LG Energy Solution stated that it aims to start mass production of cylindrical cells at the Arizona facility in 2025, which are expected to be eligible for tax credits under the Inflation Reduction Act. With the introduction of cylindrical cells manufactured in the United States, Proterra plans to build battery systems that meet content requirements under the United States-Mexico-Canada Agreement (USMCA).

Since 2016, Proterra and LG Energy Solution engineering teams have been collaborating to maximize cell performance to meet the stringent requirements of commercial vehicle markets. The cylindrical cells to be manufactured at the new Queen Creek, Arizona battery manufacturing complex will feature a new, high nickel NCMA chemistry ideal for commercial vehicles and industrial applications.

Designed and manufactured in the United States, Proterra’s battery systems have been proven through more than 35 million service miles driven in commercial vehicle applications and selected by leading commercial vehicle manufacturers to electrify delivery vehicles, construction equipment, school buses, coach buses, and more.
