Tesla Expands Berlin Battery Push With Fresh $250-Million Investment
Tesla is stepping up its investment plans in Germany, committing almost $250 million more towards battery cell production at its Grunheide factory near Berlin. The latest investment will more than double the site’s planned production capacity annually, while also creating over 1,500 battery-related jobs.
“The ramp-up of battery cell production will also be accompanied by a significant increase in labour demand,” the US electric vehicle maker said in a statement, estimating its staffing needs in battery cell production at more than 1,500 employees. The company added that recruitment for those roles has already begun, with battery cell production expected to start in the first half of 2027.
Tesla currently employs almost 11,000 people at Gruenheide, which remains the company’s only gigafactory in Europe.
From 8 GWh To 18 GWh
With the fresh investment, Tesla plans to increase annual production capacity from a previously planned 8 gigawatt hours (GWh) to 18 GWh.
Back in December 2025, the company announced investments to the tune of 1 billion euros ($1.2 billion) for the Gruenheide site, located south-east of Berlin, as it works towards bringing battery cell and vehicle production under one roof from next year.
Tesla’s broader strategy centres around large-scale vertical integration in Europe.
The company had outlined its long-term vision in December, stating, “From battery cells to electric vehicles, everything is expected to be produced at a single location starting in 2027.”
If the 18 GWh target is achieved, the Grunheide facility could produce enough battery cells for about 250,000 to 350,000 vehicles annually, depending on pack size. That would significantly exceed the factory’s current vehicle output.
A Factory In Recovery Mode
The latest expansion also comes at a crucial time for Giga Berlin, which has been working through a difficult period following a sharp slowdown in European demand.
Earlier this year, the factory was reportedly operating at only 40% capacity after Tesla’s European sales dropped 28% in 2025, while registrations in Germany fell 48% in the same year.
During the downturn, news reports stated that Tesla had cut around 1,700 jobs at the plant.
But demand for the refreshed Model Y appears to have improved the outlook. In April, Tesla announced plans to hire 1,000 additional workers, increase production by 20%, and convert around 500 temporary workers into permanent employees.
