SPARKS, NV—Tesla Inc. plans to invest more than $3.6 billion at its 5.4-million-square-foot gigafactory here. The automaker will build two new facilities at the sight, which is located just east of Reno.

One factory will mass-produce 4680-type cylindrical battery cells. Tesla claims the plant will have a capacity to produce enough batteries for 1.5 million light-duty vehicles annually. The company also plans to build a new plant to assemble its Semi truck.

According to Tesla, the Class 8 truck is capable of traveling up to 500 miles per charge, accelerating from 0 to 60 mph in 20 seconds and recharging up to 70 percent of its range in 30 minutes. It features a unique design, including a centrally located driver’s seat that is flanked by two display screens.

A fleet of 15 trucks owned by PepsiCo’s Frito-Lay Inc. subsidiary are currently operating in northern California. The company’s 500,000-square-foot production facility in Modesto is a showcase for sustainable manufacturing, warehousing and distribution technologies.

Each electric truck is equipped with a 1,000-kiolwatt battery pack. The Frito-Lay facility features four Tesla 750-kilowatt-hour charging stations that provide the semis with up to 400 miles of range after one hour of charging. In addition, the factory operates a fleet of six Peterbilt 220EV electric box trucks that are used for last-mile delivery applications.
