Hyundai's second battery factory in Georgia is up and running.

At full capacity, it can produce enough packs for hundreds of thousands of EVs annually.

However, rocky demand for EVs means it's unclear when production will scale up.

The lights are officially on at Hyundai Motor Group and SK On's $5 billion battery facility in Bartow County, Georgia.

It's among the state's largest economic development projects, aiming to further onshore battery production for Hyundai and Kia and build out a full ecosystem of EV manufacturing that could pay off for years to come if EV demand truly takes off.
