The $5 billion factory, Tesla’s first in Europe, is central to Musk’s ambitions to pass European market leader Volkswagen.
The plant is set to produce over 500,000 battery-electric vehicles a year, while its battery plant will generate over 50 gigawatt hours a year.
Musk originally wanted to start production on last summer, but the approval process was delayed because Tesla added a battery factory to the application for the car assembly, adding to delays caused by environmental objections.
