Gigafactory

Gigafactory is a neologism introduced by electric vehicle manufacturer Tesla in 2013 to refer to the company's first major manufacturing facility outside of the original Tesla Fremont Factory in California. At the time the facility was going to be called "Gigafactory" and no location had been chosen. The completed facility is now called Gigafactory Nevada (or Gigafactory 1) because Tesla has now constructed several other large facilities in multiple countries.

For the first gigafactory, Tesla partnered with Panasonic to produce battery cells at the same facility where the vehicles would be manufactured, creating economies of scale and improving control of the battery supply chain. By locating two major manufacturing facilities within the same structure, Gigafactory Nevada notably became the second-largest building in the world (by volume) once construction was complete.

More recent Tesla factories such as Gigafactory Berlin produce battery cells, battery packs, electric drivetrains, and other components which are incorporated into finished electric vehicle assemblies at the same facility using advanced robotics.{{cite web | url=https://www.youtube.com/watch?v=7-4yOx1CnXE | title=Flying Through Giga Berlin | website=YouTube }} This level of vertical integration allows Tesla to produce vehicles more quickly and reduce its exposure to supply chain problems.{{cite web | url=https://electrek.co/2022/05/26/tesla-moves-expand-gigafactory-berlin/ | title=Tesla moves to expand Gigafactory Berlin on new 250-acre land | date=26 May 2022 }} Conversely Gigafactory New York produces photovoltaic cells and Tesla Supercharger assemblies but does not produce batteries or vehicles, broadening usage of the term.

The term "gigafactory" has also been adopted by other companies which are involved in the manufacture of electric vehicles and other clean tech products. Established automobile manufacturers such as Jaguar Land Rover and Volkswagen now use the term to refer to their own electric vehicle factories. Newer companies such as Stellantis have also embraced the term{{cite web | url=https://www.stellantis.com/en/news/press-releases/2023/may/stellantis-electrification-transition-in-full-swing-with-first-acc-battery-gigafactory-inaugurated-in-france | title=Stellantis Electrification Transition in Full Swing with First ACC Battery Gigafactory Inaugurated in France }} by referring to four new "gigafactories" in France which will produce lithium-ion batteries for electric vehicles.
