The new plant in Nikola, Arizona, officially broke ground.

According tomedia reports, this is an important day for Nikola.

The ceremony is expected to kick-start a huge construction project that will put a 1m-square-foot factory into operation over the next three years.

The new plant in Nikola, Arizona, officially broke ground.

Nikola said the first phase of construction would be completed by the end of 2021 and the final construction of the second phase would be completed within the next 12-18 months.

The plant will eventually be able to produce 35,000 semi-trailer trucks a year and deploy both The Nikola Two and Tre on north American and European roads. Two is a fuel cell and an electric semi-trailer truck, while Tre is more focused on the flat-headed style needed in the European market. Nikola also said it plans to start production of Tre in Germany in partnership with Italian truck maker Iveco. But the production will eventually be transferred to the new plant in Arizona.

There are now companies that have ordered Nikola’s semi-trailer. Most notably, Budweiser brewer Anheuser-Busch ordered 800. The company shipped a batch of beer to the corporate center in St. Louis, Missouri, through Nikola Two last year.
